Description

Technical Field

[0001] This application relates to the field of molecular detection technology, specifically to a molecular diagnostic device and a card delivery holder for the molecular diagnostic device. Background Technology

[0002] Molecular diagnostic equipment utilizes molecular diagnostic technology. Molecular diagnostic technology refers to diagnostic techniques that use nucleic acids or proteins as biomarkers for clinical testing, providing information and decision-making basis for disease prediction, diagnosis, prevention, treatment, and prognosis.

[0003] When molecular diagnostic equipment tests the test cards, the test cards need to be transported to the testing station for testing, so a test card transport device is required. Summary of the Invention

[0004] One aspect of this application provides a test card delivery holder for a molecular diagnostic device, comprising:

[0005] A pressure plate is provided with a first slide rail assembly, allowing the pressure plate to slide in the sliding direction of the first slide rail assembly; and

[0006] A baggage check-in component for holding the inspection card, the baggage check-in component comprising:

[0007] A sliding frame, having an abutting force with the pressing plate in the sliding direction, so that the sliding frame slides together with the pressing plate in the sliding direction under the action of the abutting force; and

[0008] A card holder, connected to the sliding frame, is used to place the detection card so that the detection card is located on the side of the pressure plate away from the sliding frame in the sliding direction. The pressure plate is configured to move toward the detection card when the sliding frame is subjected to force to overcome the abutting force and can move to a position to abut the detection card.

[0009] On the other hand, this application also provides a test card delivery holder for a molecular diagnostic device, comprising:

[0010] The pressure plate is equipped with a first slide rail assembly; and

[0011] A baggage check-in component for holding the inspection card, the baggage check-in component comprising:

[0012] A sliding frame is provided with a second slide rail assembly, the sliding direction of the second slide rail assembly being consistent with the sliding direction of the first slide rail assembly; and

[0013] The card holder is slidably connected to the sliding frame to slide to the position where the detection card is installed. The detection card is located on the side of the pressure plate away from the sliding frame in the sliding direction of the second slide rail assembly. The pressure plate is configured to move toward the detection card and can move to a position where it abuts against the detection card.

[0014] On the other hand, this application also provides a molecular diagnostic device, comprising:

[0015] The frame is a type of frame structure.

[0016] A pressure plate, slidably connected to the frame, is slidable relative to the frame in the sliding direction; and

[0017] A baggage check-in component for holding the inspection card, the baggage check-in component comprising:

[0018] A sliding frame, slidably connected to the frame for sliding relative to the frame in the sliding direction, the sliding frame having an abutting force with the pressure plate in the sliding direction, so that the sliding frame, under the action of the abutting force, slides together with the pressure plate relative to the frame in the sliding direction; and

[0019] The card holder is slidably connected to the sliding frame. The card holder is used to place the detection card so that the detection card is located on the side of the pressure plate away from the sliding frame in the sliding direction. The pressure plate is configured to move toward the detection card when the sliding frame is subjected to force to overcome the abutting force and can move to a position to abut the detection card.

[0020] The test card transporter in this application uses a pressure plate to drive the transport component to transport the test card. The pressure plate and transport component move together through a contact force. Furthermore, when the pressure plate overcomes the contact force, the transport component and pressure plate can be prevented from moving together, reducing internal damage to the molecular diagnostic equipment. For example, when the transport component, driven by the pressure plate, transports the test card to the test card holder, the interaction between the transport component and the test card holder caused by continued movement of the pressure plate during contact is minimized.

[0563] The slot 1111 can mate with the card delivery seat 20, allowing the card delivery seat 20 to extend into or slide within the slot 1111. In some embodiments, the extending direction of the slot 1111 is consistent with the sliding direction of the card delivery seat 20 relative to the frame 10, such as the frame body 11. In some embodiments, the slot 1111 can be omitted if the top plate 111 does not need to provide space for the card delivery seat 20.

One end of the reinforcing plate 113 can be connected to the lower part of one support leg 112, and the other end can be connected to the lower part of another support leg 112 to achieve relative stability between the two support legs 112, thereby enhancing the stability of the support legs 112. The connection method between the reinforcing plate 113 and one support leg 112 can be screwed, plugged in, snap-fitted, welded, or glued, etc., which will not be elaborated further. Understandably, to achieve the stability of the support legs 112, the reinforcement plate 113 is not limited to being connected to the lower part of one support leg 112; one end of the reinforcing plate 113 can also be connected and fixed to the top or middle of the support leg 112, or other parts.

[0585] The drive assembly 121 can be indirectly connected to the lead screw assembly 122 via a conveyor belt, or directly connected to the lead screw assembly 122 for transmission via the lead screw assembly 122. The lead screw assembly 122 is connected to the card delivery seat 20. Driven by the drive assembly 121, the lead screw assembly 122 can push the card delivery seat 20 to slide on the frame body 11, for example, the first guide rail 1126, thereby achieving the effect of the card delivery seat 20 carrying the card.

[0586] Please refer to the following: Figure 3 and Figure 4 , Figure 4 for Figure 3 Exploded view of drive assembly 121. Drive assembly 121 may include a mounting bracket 1211 mounted on the rack body 11, for example, at mounting hole 1112, a first drive member 1212 mounted on the mounting bracket 1211, and a synchronization assembly 1213 mounted on the mounting bracket 1211. The first drive member 1212 is electrically connected to the control circuit board 40 to move under the control of the control circuit board 40.

[0587] Synchronization component 1213 is connected to the first drive component 1212 and is used for transmission under the drive of the first drive component 1212. Synchronization component 1213 can be indirectly connected to lead screw assembly 122 via a conveyor belt, or it can be directly connected to lead screw assembly 122 to drive transmission via lead screw assembly 122.

[0588] Mounting bracket 1211 may include a mounting plate 1214 on one side for mounting the first drive member 1212 and a clamping plate 1215 on the other side of the mounting plate 1214 for fastening to the mounting plate 1214.

[0589] The mounting plate 1214 may be made of rigid materials such as plastic or metal. The mounting plate 1214 may have a plate-like structure, or other shapes, which will not be elaborated further. The mounting plate 1214 may be placed within the mounting hole 1112. In some embodiments, the mounting plate 1214 may also be placed outside the mounting hole 1112. In one embodiment, the mounting plate 1214 may be integrally formed with the top plate 111. In one embodiment, the mounting plate 1214 may be omitted, and the top plate 111 may omit the mounting hole 1112 to replace the mounting plate 1214.

[0590] The clamping plate 1215 may include a clamping plate body 1215a disposed opposite to the mounting plate 1214 and a spacer 1215b disposed between the clamping plate body 1215a and the mounting plate 1214. The clamping plate body 1215a may be located on the side of the mounting plate 1214 away from the first driving member 1212. The spacer 1215b is used to control the gap between the clamping plate body 1215a and the mounting plate 1214.

[0591] The clamping plate body 1215a can be made of rigid materials such as plastic or metal. The clamping plate body 1215a can be plate-shaped, or other shapes, which will not be elaborated here. The clamping plate body 1215a can be placed outside the mounting hole 1112 and located above the top plate 111.

[0592] In some embodiments, when the mounting plate 1214 is positioned outside the mounting hole 1112, for example, above or below the top plate 111, the clamping plate body 1215a may be placed within the mounting hole 1112. In one embodiment, the mounting plate 1214 may be integral with the top plate 111. In one embodiment, the clamping plate body 1215a may be omitted, and the top plate 111 may omit the mounting hole 1112 in place of the clamping plate body 1215a.

[0593] The spacer 1215b is connected and fixed to the clamping plate body 1215a and the mounting plate 1214 respectively, so as to form a space for installing the synchronization component 1213 in the gap between the clamping plate body 1215a and the mounting plate 1214.

[0594] In one embodiment, the spacer 1215b may be a spacer plate. The spacer 1215b, for example, a spacer plate, can be connected and fixed to the mounting plate 1214 and the clamping plate body 1215a respectively by means of screwing, plugging, snapping, bonding, welding, etc.

[0595] In one embodiment, the spacer 1215b may also be a bolt, screw, or other similar structure.

[0596] In one embodiment, the spacer 1215b may be integrally formed with the clamping plate body 1215a. In another embodiment, the spacer 1215b may also be integrally formed with the mounting plate 1214. In one embodiment, the spacer 1215b, the mounting plate 1214, and the clamping plate body 1215a are integrally formed.

[0597] When the mounting bracket 1211 is installed on the top plate 111, the clamping plate body 1215a is located on the side of the top plate 111 away from the support leg 112. The spacer 1215b is connected and fixed to the top plate 111 at the mounting hole 1112 by means of screwing, plugging, snapping, welding, or bonding. Simultaneously, when the mounting plate 1214 is located within the mounting hole 1112, the spacer 1215b extends into the mounting hole 1112 and is connected and fixed to the mounting plate 1214 by means of screwing, plugging, snapping, welding, or bonding, so that the first driving member 1212 is located at the bottom of the top plate 111, achieving a reasonable spatial arrangement of the molecular diagnostic equipment 100. When the mounting plate 1214 and the clamping plate 1215 are located at the top of the top plate 111, the spacer 1215b is connected and fixed to the mounting plate 1214 by means of screwing, plugging, snapping, welding, or bonding. Mounting plate 1214 is connected and fixed to top plate 111 by means of screwing, plugging, snap-fitting, welding, or bonding. When mounting plate 1214 is located at the bottom of top plate 111 and clamping plate 1215 is located at the top of top plate 111, spacer 1215b can pass through mounting hole 1112 and be connected and fixed to mounting plate 1214 by means of screwing, plugging, snap-fitting, welding, or bonding.

[0598] The first driving member 1212 is installed on the side of the mounting plate 1214 away from the clamping plate body 1215a. The first driving member 1212 and the mounting plate 1214 can be connected and fixed by means of screwing, plugging, snapping, welding, bonding, etc. In some embodiments, the first driving member 1212 can also be installed on the side of the mounting plate 1214 closer to the clamping plate body 1215a.

[0599] The first driving element 1212 can be a motor. The output shaft of the motor can pass through the mounting plate 1214 and extend between the mounting plate 1214 and the clamping plate body 1215a. In one embodiment, the output shaft of the motor can also pass through the clamping plate body 1215a, or it can be rotatably connected to the clamping plate body 1215a without passing through it. In one embodiment, the first driving element 1212 can also be other power sources that can drive the synchronous component 1213 to move, which will not be described in detail.

[0600] The synchronization component 1213 may include a first gear 1216 mounted on the output shaft of the first drive member 1212, and a first transmission gear set 1217 and a second transmission gear set 1218 respectively meshing with the first gear 1216.

[0601] The first gear 1216 rotates when the first drive member 1212 is activated. The first transmission gear set 1217 and the second transmission gear set 1218 are rotatably connected to the mounting bracket 1211. The first transmission gear set 1217 and the second transmission gear set 1218 can rotate synchronously when the first gear 1216 rotates, with one rotating clockwise and the other counterclockwise.

[0602] The rotating shaft of the first transmission gear set 1217 is arranged parallel to the output shaft of the first driving component 1212, such as a motor. The rotating shaft of the first transmission gear set 1217 is rotatably connected to the mounting plate 1214 and the clamping plate body 1215a, respectively.

[0603] The first transmission gear set 1217 may include a second gear 1217a and a first rotating wheel 1217b arranged coaxially. The second gear 1217a may mesh with the first gear 1216. The first rotating wheel 1217b may be connected to the lead screw assembly 122 via a conveyor belt or directly to the lead screw assembly 122 for transmission via the lead screw assembly 122.

[0604] The rotating shaft of the second transmission gear set 1218 is arranged parallel to the output shaft of the first driving component 1212, such as a motor. The rotating shaft of the second transmission gear set 1218 is rotatably connected to the mounting plate 1214 and the clamping plate body 1215a, respectively.

[0605] The second transmission gear set 1218 may include a third gear 1218a and a second rotating wheel 1218b coaxially arranged. The third gear 1218a may mesh with the first gear 1216. The second rotating wheel 1218b may be connected to the lead screw assembly 122 via a conveyor belt or directly to the lead screw assembly 122 for transmission via the lead screw assembly 122.

[0606] Understandably, the terms "first gear," "second gear," "third gear," and "gear" can be interchanged in some embodiments. For example, in one embodiment, the "first gear" in other embodiments is referred to as the "second gear," and correspondingly, the "second gear" in other embodiments is referred to as the "first gear."

[0607] It is understood that the synchronization component 1213 is not limited to the embodiments mentioned above, and it can also be other types of synchronization components. In addition, when the synchronization component 1213 includes gears and transmission gear sets, it may also include other structures, and the number of gears and the structure and number of transmission gear sets can be set according to the actual situation.

[0608] Please see Figure 5 , Figure 5 for Figure 3 The diagram shows the connection relationship between the main frame 11 and the lead screw assembly 122. The lead screw assembly 122 may include two lead screws, such as a first lead screw 1221 and a second lead screw 1222. In some embodiments, the number of lead screws may also be one of 1, 3, 4, 5, 6...

[0609] In some embodiments, in order to achieve stable movement of the detection card delivery seat 20, the number of lead screws may be at least two.

[0610] Two lead screws, such as a first lead screw 1221 and a second lead screw 1222, are respectively disposed on both sides in a direction perpendicular to the extension direction of the strip hole 1111. The first lead screw 1221 can be connected to the first transmission gear set 1217, such as the first rotating wheel 1217b, via a conveyor belt or directly, and the rotation of the first transmission gear set 1217, such as the first rotating wheel 1217b, realizes the rotation of the first lead screw 1221. The second lead screw 1222 can be connected to the second transmission gear set 1218, such as the second rotating wheel 1218b, via a conveyor belt or directly, and the rotation of the second transmission gear set 1218, such as the second rotating wheel 1218b, realizes the rotation of the second lead screw 1222.

[0611] Each lead screw, such as the second lead screw 1222, may include a bearing 1223 mounted on the frame body 11, such as the connecting part 1113, a lead screw body 1224 rotatably connected to the bearing 1223 and rotatably connected to the frame body 11, such as the reinforcing plate 113, and a third wheel 1225 mounted on the end of the lead screw body 1224.

[0612] The bearing 1223 is sleeved around the lead screw body 1224 for rotatable connection. The lead screw body 1224 may be a rod-shaped structure with external threads on its surface. The extension direction of the lead screw body 1224 may be consistent with the extension direction of the first guide rail 1126; however, in some embodiments, the extension direction of the lead screw body 1224 may not be consistent with the extension direction of the first guide rail 1126. The lead screw body 1224 may be threadedly connected to the detection card conveyor 20. The third rotating wheel 1225 and the second rotating wheel 1218b are located on the same side of the frame body 11, for example, on the top plate 111, or on the top of the top plate 111.

[0613] In one embodiment, the shaft of the third rotating wheel 1225 is parallel to the shaft of the second rotating wheel 1218b. In another embodiment, the bearing 1223 may be omitted, and the lead screw body 1224 may be disposed in the connecting part 1113, for example, in the through hole, and directly rotatably connected to the top plate 111.

[0614] Understandably, the terms "first wheel," "second wheel," "third wheel," and "wheel" can be used interchangeably in some embodiments. For example, in one embodiment, the "first wheel" in other embodiments is referred to as the "second wheel," and correspondingly, the "second wheel" in other embodiments is referred to as the "first wheel."

[0615] In one embodiment, in the first lead screw 1221, the lead screw body 1224 is rotatably connected to a reinforcing plate 113, such as a first reinforcing plate 1131. In the second lead screw 1222, the lead screw body 1224 is rotatably connected to a reinforcing plate 113, such as a third reinforcing plate 1133. The third wheel 1225 of the first lead screw 1221 can be connected to the first wheel 1217b of the first transmission gear set 1217 via a conveyor belt. The third wheel 1225 of the second lead screw 1222 can be connected to the second wheel 1218b of the second transmission gear set 1218 via a conveyor belt.

[0616] Understandably, the lead screw assembly 122 and the first guide rail 1126 are designed to enable the card delivery seat 20 to slide on the frame 10, thereby facilitating the transport of the card. Therefore, if the number of lead screws in the lead screw assembly 122 is sufficient to allow the card delivery seat 20 to slide stably and normally on the frame 10, the first guide rail 1126 may not be necessary on the molecular diagnostic equipment 100.

[0617] Please refer to it again. Figure 3 The frame 10, for example, has a circuit mounting plate 13 on the outer side of the frame body 11 for mounting the control circuit board 40. The circuit mounting plate 13 is located on the same side as the support leg 112 on the top plate 111. The circuit mounting plate 13 is located on the same side as the second support leg 1122 and the third support leg 1123.

[0618] Please refer to the following: Figure 3 , Figure 6 and Figure 7 , Figure 6 and Figure 7 They are respectively Figure 3 The circuit mounting plate 13 is shown in perspective from different angles. The circuit mounting plate 13 can be made of rigid materials such as plastic or metal. The circuit mounting plate 13 may include a mounting plate body 131. The mounting plate body 131 has a plate-like structure and can be located on the same side of the second leg 1122 and the third leg 1123. In some embodiments, the mounting plate body 131 can also be directly fixed to the second leg 1122 and the third leg 1123. The side of the mounting plate body 131 away from the leg 112 is used to mount the control circuit board 40. Through holes 1311 can be formed on the mounting plate body 131 so that circuit traces pass through the through holes 1311 from inside the frame body 11 and are electrically connected to the control circuit board 40. In one embodiment, the mounting plate body 131 can also be connected and fixed to a reinforcing plate 113, such as the second reinforcing plate 1132. A connecting post 1312 is provided on the side of the mounting plate body 131 away from the leg 112 for mounting the control circuit board 40, preventing the control circuit board 40 from directly contacting the mounting plate body 131. The connecting post 1312 can be used to install the control circuit board 40 through screwing, plugging, soldering, or other methods. The mounting plate body 131 can isolate the control circuit board 40 from the rack body 11, preventing factors such as temperature inside the rack body 11 from interfering with the control circuit board 40. Of course, in some embodiments, when isolating the control circuit board 40 is not required, the mounting plate body 131 can be omitted, and the connecting post 1312 can be directly set on the rack 10, such as the rack body 11. In one embodiment, the mounting plate body 131 can be an integral structure with the rack body 11.

[0619] The mounting plate body 131 may have a first surrounding plate 132 near the edge of the support leg 112, such as the third support leg 1123. The first surrounding plate 132 can be bent from the edge of the mounting plate body 131 toward the third support leg 1123 to cover the gap between the mounting plate body 131 and the third support leg 1123, thus providing isolation at the third support leg 1123. In one embodiment, the first surrounding plate 132 may be fixed to the third support leg 1123 by means of screwing, snap-fitting, plugging, welding, or bonding. In some embodiments, the first surrounding plate 132 may be omitted.

[0620] A second surrounding plate 133 may be provided on the edge of the mounting plate body 131 near the top plate 111. The second surrounding plate 133 may be bent from the edge of the mounting plate body 131 toward the third support leg 1123. The second surrounding plate 133 may be connected and fixed to the top plate 111. In one embodiment, the second surrounding plate 133 may be fixed to the top plate 111 by means of screwing, snap-fitting, plugging, welding, or bonding. In some embodiments, the second surrounding plate 133 may be provided with an opening 1331 to make way for components mounted on the top plate 111. In some embodiments, the second surrounding plate 133 may be omitted.

[0621] A third enclosure 134 may be provided on the edge of the mounting plate body 131 near the support leg 112, such as the second support leg 1122. The third enclosure 134 can be bent from the edge of the mounting plate body 131 toward the second support leg 1122 to cover the gap between the mounting plate body 131 and the second support leg 1122, thus providing isolation at the second support leg 1122. In one embodiment, the third enclosure 134 may be fixed to the second support leg 1122 by means of screwing, snap-fitting, plugging, welding, or bonding. In some embodiments, the third enclosure 134 may be omitted.

[0622] Understandably, the terms "first enclosure", "second enclosure", "third enclosure", and "enclosure" can be interchanged in some embodiments. For example, in one embodiment, the "first enclosure" in other embodiments is referred to as the "second enclosure", and correspondingly, the "second enclosure" in other embodiments is referred to as the "first enclosure".

[0623] Please refer to it again. Figure 3 The rack 10, for example, the rack body 11, is equipped with a barcode scanner 14 electrically connected to the control circuit board 40. The barcode scanner 14 can scan information markings on the test card, such as QR codes or barcodes, and transmit the images to the control circuit board 40. The control circuit board 40 recognizes the images and obtains relevant information about the test card. The barcode scanner 14 can be positioned on the sliding path of the test card delivery seat 20 relative to the rack 10, so that when the test card is placed on the test card delivery seat 20, the information markings on the test card are scanned by the barcode scanner 14.

[0624] In one embodiment, the barcode scanner 14 may be disposed on the path along which the card delivery seat 20 slides within the barcode hole 1111. For example, the barcode scanner 14 may be disposed on the reinforcing plate 113, such as the fourth reinforcing plate 1134. The barcode hole 1111 extends away from the mounting hole 1112, that is, the barcode hole 1111 extends towards the fourth reinforcing plate 1134. In one embodiment, the extension of the barcode hole 1111 away from the mounting hole 1112 may extend above the fourth reinforcing plate 1134.

[0625] In one embodiment, the barcode scanner 14 is mounted on a reinforcing plate 113, such as a fourth reinforcing plate 1134. The card delivery seat 20 slides along the extension direction of the stripe hole 1111 and slides above the barcode scanner 14. At this time, when a card is placed on the card delivery seat 20, the barcode scanner 14 immediately scans the information markings on the card.

[0626] Understandably, the barcode scanner 14 can also be located in other positions on the rack 10, such as inside the rack 10. Additionally, in some embodiments, when the molecular diagnostic device 100 has a housing, the isolation door in the above embodiments will be located on the fourth reinforcing plate 1134 of the housing and positioned opposite the barcode scanner 14. This allows the test card to slide relative to the rack 10 to the isolation door, placing the test card on the test card transport seat 20, and the barcode scanner 14 to automatically scan the information markings on the test card. In one embodiment, the barcode scanner 14 can also be located on the housing.

[0627] Please refer to it again. Figure 5 The frame 10, for example, the top plate 111, is equipped with a first limit switch 15 electrically connected to the control circuit board 40. The first limit switch 15 is located below the top plate 111. The first limit switch 15 is located on the travel distance of the card delivery seat 20 relative to the frame 10, so that when the card delivery seat 20 slides, it triggers the first limit switch 15, causing the first limit switch 15 to generate a control signal and transmit it to the control circuit board 40. The control circuit board 40 then controls the operation of the card delivery seat 20 according to the control signal and stops the card delivery seat 20, so that the card delivery seat 20 stops at a predetermined position, thereby limiting the movement of the card delivery seat 20.

[0628] In one embodiment, the first limit switch 15 is used to limit the position of the detection card delivery seat 20 when it slides along the extension direction of the strip hole 1111.

[0629] In one embodiment, the first limit switch 15 is located on the top plate 111 near the strip hole 1111. Specifically, the first limit switch 15 may be located at the end of the strip hole 1111 away from the mounting hole 1112. Of course, the first limit switch 15 may also be located at other positions on the frame 10, or it may be located on the housing if the molecular diagnostic device 100 is equipped with a housing.

[0630] In some embodiments, the first limit switch 15 may be an optocoupler limit switch, specifically a slotted optocoupler. A groove is provided between the limiting light-emitting part and the limiting light-receiving part of the slotted optocoupler. When the portion of the card delivery seat 20 is placed within the groove, the card delivery seat 20 blocks the light transmission between the limiting light-emitting part and the limiting light-receiving part. The slotted optocoupler then generates a control signal and transmits it to the control circuit board 40, so that the card delivery seat 20 stops operating under the control of the control circuit board 40, thereby causing the card delivery seat 20 to remain at a predetermined position.

[0631] Please see Figure 8 , Figure 8 for Figure 3 A partial structural diagram of the frame 10. For example, the frame body 11 may be equipped with a second limit switch 16 electrically connected to the control circuit board 40 to limit the movement of the card delivery seat 20. The second limit switch 16 may be located on the travel distance of the card delivery seat 20 sliding on the first guide rail 1126 to limit the position of the card delivery seat 20 when it slides on the first guide rail 1126.

[0632] The second limit switch 16 is triggered when the card delivery seat 20 slides on the first guide rail 1126, generating a control signal and transmitting it to the control circuit board 40. The control circuit board 40 controls the operation of the card delivery seat 20 according to the control signal and stops the card delivery seat 20 so that the card delivery seat 20 stays at a predetermined position, thereby limiting the operation of the card delivery seat 20.

[0633] Please refer to the following: Figure 8 and Figure 9 , Figure 9 for Figure 8 A schematic diagram of the structure of the second limit switch 16 is shown. The second limit switch 16 may include a mounting housing 161 mounted on a support leg 112, such as a third support leg 1123, and a first sub-limit switch 162 and a second sub-limit switch 163 disposed on the mounting housing 161. Both the first sub-limit switch 162 and the second sub-limit switch 163 are located within the sliding stroke of the detection card delivery seat 20 on the first guide rail 1126, allowing the detection card delivery seat 20 to slide within the stroke between the first sub-limit switch 162 and the second sub-limit switch 163. Both the first sub-limit switch 162 and the second sub-limit switch 163 are electrically connected to the control circuit board 40.

[0634] Understandably, the terms "first limit switch," "second limit switch," "sub-limit switch," "first sub-limit switch," "second sub-limit switch," and "limit switch" can be interchanged in some embodiments. For example, in one embodiment, the "first limit switch" in other embodiments is referred to as the "second limit switch," and correspondingly, the "second limit switch" in other embodiments is referred to as the "first limit switch."

[0635] The mounting housing 161 is made of rigid materials such as plastic or metal. The mounting housing 161 is shell-shaped. The mounting housing 161 can be installed on the frame body 11, such as the third leg 1123. The mounting housing 161 can be fixed to the frame body 11, such as the third leg 1123, by means of screwing, snap-fitting, plugging, welding, or bonding.

[0636] The mounting housing 161 can be located on the side of the third leg 1123 near the circuit mounting plate 13. Of course, the mounting housing 161 can also be installed in other positions on the rack 10, which will not be described in detail here.

[0637] The first sub-limit switch 162 and the second sub-limit switch 163 can be located on the same side of the mounting housing 161. Specifically, the first sub-limit switch 162 and the second sub-limit switch 163 can be located on the side of the mounting housing 161 away from the circuit mounting plate 13.

[0638] The first sub-limit switch 162 can be triggered to generate a signal and transmit it to the control circuit board 40 when the card delivery seat 20 slides towards the card detection seat 30. The control circuit board 40 can then control the operation of the card delivery seat 20 according to the control signal and stop the card delivery seat 20 so that the card delivery seat 20 stays at a predetermined position, thereby limiting the position of the card delivery seat 20 when it slides towards the card detection seat 30.

[0639] The second sub-limit switch 163 can be triggered to generate a signal and transmit it to the control circuit board 40 when the detection card conveyor 20 slides away from the detection card detection seat 30 (i.e., slides towards the top plate 111). The control circuit board 40 can then control the operation of the detection card conveyor 20 according to the control signal and stop the operation of the detection card conveyor 20 so that the detection card conveyor 20 stays at a predetermined position. This achieves position limitation of the detection card conveyor 20 when it slides towards the top plate 111, reducing mutual damage caused by contact between the detection card conveyor 20 and the top plate 111.

[0640] In one embodiment, the first sub-limit switch 162 and the second sub-limit switch 163 can both be optocoupler limit switches. When the portion of the detection card delivery seat 20 is placed in the groove, the detection card delivery seat 20 blocks the light transmission between the limiting light-emitting part and the limiting light-receiving part. The slot-shaped optocoupler then generates a control signal and transmits it to the control circuit board 40 so that the first driving device 12, such as the driving assembly 121, stops operating under the control of the control circuit board 40, thereby causing the detection card delivery seat 20 to stop at a predetermined position.

[0641] Understandably, the first sub-limit switch 162 and the second sub-limit switch 163 can also be limit switches, proximity switches, or other limit devices. The first sub-limit switch 162 and the second sub-limit switch 163 can also be sensors with limit functions.

[0642] In one embodiment, the mounting housing 161 can be omitted, and the first sub-limit switch 162 and the second sub-limit switch 163 can be directly disposed at other locations on the frame 10. Of course, if the molecular diagnostic device 100 is equipped with a housing, the mounting housing 161 can also be disposed on the housing. Furthermore, the mounting housing 161 can be omitted, and the first sub-limit switch 162 and the second sub-limit switch 163 can be directly disposed on the housing.

[0643] Detection card delivery seat 20

[0644] Please see Figure 2 The test card transport base 20 may include a pressure plate 50 and a transport assembly 60 mounted on the frame 10, such as the first guide rail 1126. The transport assembly 60 is used to hold the test card. The pressure plate 50 is connected to the first drive device 12, and slides on the first guide rail 1126 under the action of the first drive device 12, thereby driving the transport assembly 60 to slide on the first guide rail 1126. The transport assembly 60 can transport the test card and place it onto the test card testing base 30.

[0645] 50 pressure plate

[0646] Please see Figure 10 , Figure 10 For this application Figure 2An exploded view of the pressure plate 50. The pressure plate 50 may include a first housing 51 mounted on a frame 10, such as a lead screw body 1224; an electromagnetic component 52 disposed on the side of the first housing 51 facing the detection card detection seat 30; a clamping component 53 for fixing the detection card on the transport assembly 60; a heating assembly 54 disposed on the first housing 51; a first circuit board 55 mounted on the first housing 51 and electrically connected to the electromagnetic component 52 and the heating assembly 54 respectively; a locking component 56 mounted on the first housing 51 for fixing the clamping component 53; a second housing 57 covering the side of the first housing 51 away from the electromagnetic component 52; and a first slide rail assembly 58 disposed on the first housing 51 and mounted on the frame 10, such as a first guide rail 1126. The first housing 51 and the second housing 57 are fastened together to form the pressure plate body. The first circuit board 55 may be electrically connected to a control circuit board 40. The electromagnetic component 52 may generate a magnetic force under the control of the control circuit board 40 to attract the clamping component 53 onto the first housing 51. The electromagnetic component 52 can eliminate magnetic force under the control of the control circuit board 40 to avoid attracting the clamping component 53. The heating component 54 can heat the detection card under the control of the control circuit board 40. The first slide rail assembly 58 can slide on the frame 10, for example, the first guide rail 1126. The first housing 51 is connected to the frame 10, for example, the lead screw body 1224, so as to slide in the extension direction of the first guide rail 1126 under the rotation of the lead screw body 1224.

[0647] Please see Figure 11 and Figure 12 , Figure 11 and Figure 12 They are respectively Figure 10 Schematic diagrams of the first housing 51 from different perspectives. The first housing 51 can be made of rigid materials such as plastic or metal. The first housing 51 can be plate-shaped, or it can be other shapes, which will not be elaborated further. The first housing 51 may include a housing body 511. A receiving groove 512 is provided in the middle of the housing body 511 facing the second housing 57 to receive the first circuit board 55 and the locking member 56. The cross-section of the receiving groove 512 can be circular or other shapes.

[0648] The housing body 511 may be provided with snap-fit ​​holes 513 around the receiving groove 512 for mounting the heating assembly 54. The snap-fit ​​holes 513 may be evenly distributed circumferentially around the receiving groove 512. The number of snap-fit ​​holes 513 may be one or more. In some embodiments, the number of snap-fit ​​holes 513 may also be one of 2, 3, 4, 5, 6... In one embodiment, the number of snap-fit ​​holes 513 may specifically be 6. In one embodiment, the shape of the snap-fit ​​hole 513 is a segment of an annular structure.

[0649] The housing body 511 is provided with a notch 514 to allow space for the transport assembly 60. The notch 514 extends inward from the edge of the housing body 511 near the fourth reinforcing plate 1134. The notch 514 may be positioned opposite to the slot 1111, and the extending direction of the notch 514 may be consistent with the extending direction of the slot 1111, so that the transport assembly 60 can slide within both the slot 1111 and the notch 514 simultaneously. In one embodiment, the notch 514 is located between two adjacent snap-fit ​​holes 513.

[0650] The housing body 511 is located within the receiving groove 512 and is bent towards the second housing 57 at the edge of the notch 514 to form a sidewall 5111, thereby isolating the notch 514 and the receiving groove 512. In one embodiment, the surface of the sidewall 5111 near the second housing 57 is flush with the surface of the housing body 511 near the second housing 57. In one embodiment, the sidewall 5111 can be used to support the second housing 57.

[0651] The housing body 511 has insertion holes, such as a first insertion hole 5112 and a second insertion hole 5113, provided within the receiving groove 512, so as to install a locking member 56 at the insertion holes. In one embodiment, the insertion holes, such as the first insertion hole 5112 and the second insertion hole 5113, may be omitted.

[0652] The housing body 511 has a limiting post 5114 within the receiving groove 512 to limit the installation position of the first circuit board 55. For example, the limiting post 5114 surrounds the notch 514 to cooperate with the housing body 511 to form a space for installing the first circuit board 55, thereby limiting the installation position of the first circuit board 55. In one embodiment, the limiting post 5114 has a connecting hole 5114a so that circuit traces pass through the connecting hole 5114a from the side of the housing body 511 near the electromagnetic component 52 and extend into the receiving groove 512 to electrically connect with the first circuit board 55.

[0653] In one embodiment, the limiting post 5114 can also be used to abut against the second housing 57 to support the second housing 57. In one embodiment, the limiting post 5114 can also be omitted. In one embodiment, the connecting hole 5114a can be directly provided at other locations on the housing body 511 instead of being provided on the limiting post 5114.

[0654] The housing body 511 has a connecting post 5115 within the receiving groove 512 for mounting the first circuit board 55, thus preventing the first circuit board 55 from directly contacting the housing body 511. In one embodiment, the connecting post 5115 can be used to connect and fix the first circuit board 55 by means of screwing, plugging, snapping, bonding, welding, etc. In another embodiment, the connecting post 5115 can be omitted, and the first circuit board 55 is directly fixed within the receiving groove 512.

[0655] The housing body 511 has an edge 5116 formed by bending the edge of the snap-fit ​​hole 513 away from the second housing 57 into the snap-fit ​​hole 513 to snap-fit ​​the heating component 54 and prevent the heating component 54 from slipping off the housing body 511 from the side near the electromagnetic component 52. A communication port 5117 is provided between the snap-fit ​​hole 513 and the receiving groove 512 so that the circuit traces connected to the heating component 54 can pass through the communication port 5117 and be electrically connected to the first circuit board 55.

[0656] The housing body 511 has a first threaded portion 515 near the lead screw assembly 122, for example, the first lead screw 1221. The housing body 511 also has a second threaded portion 516 near the lead screw assembly 122, for example, the second lead screw 1222. The threaded portions, such as the first threaded portion 515 and the second threaded portion 516, may include a connecting lug 5151 extending from the housing body 511 and a threaded member 5152 mounted on the connecting lug 5151. The threaded member 5152 can be sleeved onto the lead screw assembly 122, for example, the lead screw body 1224. The threaded member 5152 has an internal thread that mates with the external thread of the lead screw body 1224, so that the housing body 511 can move in the extending direction of the lead screw assembly 122, for example, the lead screw body 1224, when the lead screw assembly 122 rotates.

[0657] The housing body 511 is provided with a positioning hole 517 for positioning the detection card.

[0658] A recessed groove 518 is provided in the middle of the surface of the housing body 511 away from the second housing 57 to accommodate the electromagnetic component 52, the clamping component 53, and the heating assembly 54. In one embodiment, the recessed groove 518 has a circular cross-section, but other shapes are also possible. The recessed groove 518 and the receiving groove 512 are arranged back-to-back with respect to the housing body 511 so that the recessed groove 518 communicates with the notch 514. Insertion holes, such as the first insertion hole 5112 and the second insertion hole 5113, are located within the recessed groove 518. The connecting hole 5114a on the limiting post 5114 is located within the recessed groove 518, and the snap-fit ​​hole 513 is located around the perimeter of the recessed groove 518. In one embodiment, the recessed groove 518 may be omitted.

[0659] In one embodiment, the housing body 511 has a plurality of receiving slots evenly distributed around its inner circumference in the relief groove 518 for mounting the electromagnetic component 52. The number of receiving slots can be multiple, specifically one of 2, 3, 4, 5, 6, etc. In one embodiment, the number of receiving slots can be two, for example, a first receiving slot 5118 and a second receiving slot 5119.

[0660] Please refer to it again. Figure 10The electromagnetic component 52 can be energized to generate a magnetic force, thereby attracting and fixing the clamping component 53. The electromagnetic component 52 may include a first electromagnet 521 and a second electromagnet 522, which are respectively electrically connected to the first circuit board 55. The first electromagnet 521 can be installed in the first receiving groove 5118. The second electromagnet 522 can be installed in the second receiving groove 5119. Specifically, the first electromagnet 521 and the second electromagnet 522 can be fixed to the housing body 511 by means of screwing, snap-fitting, plugging, welding, or bonding. In one embodiment, the circuit traces electrically connected to the first electromagnet 521 and the second electromagnet 522 pass through the connecting hole 5114a and are electrically connected to the first circuit board 55. In one embodiment, the electromagnetic component 52 may be omitted.

[0661] Please see Figure 13 , Figure 13 For this application Figure 10 A schematic diagram of the structure of the clamping member 53. The number of clamping members 53 can be one or more. In one embodiment, the number of clamping members 53 can be two, namely a first clamping member 531 and a second clamping member 532. A gap 533 is provided between the two clamping members 53. The gap 533 is positioned opposite to the slotted hole 1111 to allow space for the transport assembly 60, enabling the transport assembly 60 to move simultaneously within both the gap 533 and the slotted hole 1111.

[0662] Each clamping element 53 may be made of a rigid material such as metal, specifically a metal such as iron that can be attracted by an electromagnet under magnetic force. Of course, in some embodiments, each clamping element 53 may also be made of a rigid material such as plastic or metal so as to engage with the locking element 56.

[0663] Each clamping member 53 may be plate-shaped, generally circular or annular, or of other shapes, which will not be elaborated further. For example, the first clamping member 531 may include a clamping member body 5311. The clamping member body 5311 may be provided with a clearance portion 5312 to allow space for the detection card, thereby increasing the contact area between the clamping member body 5311 and the detection card, and thus limiting the movement of the detection card. In one embodiment, the clearance portion 5312 may be a perforation or a notch.

[0664] The first clamping member 531 has a clamping member body 5311 with a sub-yielding portion 5313 at its edge facing the second clamping member 532. The second clamping member 532 also has a clamping member body 5311 with a sub-yielding portion 5313 at its edge facing the first clamping member 531. The sub-yielding portions 5313 of the first clamping member 531 and the second clamping member 532 are disposed opposite to each other and can form a yielding portion to allow the detection card to be repositioned, thereby increasing the contact area between the clamping member body 5311 and the detection card, and thus limiting the detection card. In one embodiment, the sub-yielding portion 5313 may be a notch.

[0665] In one embodiment, the clearance portions in the above embodiments can be evenly distributed circumferentially to properly fix and limit the detection card. It is understood that the number of clearance portions can be the same as the number of card receiving holes 513 or the number of detection cards.

[0666] The clamping body 5311 is provided with a first locking part 5314 for detachable connection with the transport component 60.

[0667] In one embodiment, the first clamping member 531 and the second clamping member 532 may be an integral structure, with a gap 533 provided only at the position opposite to the strip hole 1111. The gap 533 extends inward from the edge of the clamping member 53. In another embodiment, the gap 533 may be omitted, and the clamping member 53 may be part of the transport assembly 60.

[0668] When the electromagnetic component 52 attracts the clamping component 53, one of the electromagnets in the electromagnetic component 52, such as the first electromagnet 521, can attract the surface of the first clamping component 531, such as the clamping component body 5311, while the other electromagnet, such as the second electromagnet 522, can attract the surface of the second clamping component 532, such as the clamping component body 5311.

[0669] In one embodiment, the clamping member 53 can also be locked and fixed with the locking member 56. For example, the portion of the clamping member body 5311 between two adjacent clearance portions can be clamped and fixed by the locking member 56. Of course, a corresponding connecting structure, such as a connecting column or a lifting lug, can also be provided on the clamping member body 5311 to be clamped and fixed by the locking member 56.

[0670] Please refer to it again. Figure 10 The heating assembly 54 may include a first heating element 541 installed on the side of the first housing 51, such as the housing body 511, near the second housing 57, and a second heating element 542 installed on the side of the first housing 51, such as the housing body 511, away from the second housing 57. The first heating element 541 and the second heating element 542 cooperate to heat the detection card when it comes into contact with the detection card or in a suitable scenario or position.

[0671] Understandably, the terms "first heating element," "second heating element," and "heating element" can be interchanged in some embodiments. For example, in one embodiment, the "first heating element" in other embodiments is referred to as the "second heating element," and correspondingly, the "second heating element" in other embodiments is referred to as the "first heating element."

[0672] Please see Figure 14 and Figure 15 , Figure 14 and Figure 15 They are respectively Figure 10Schematic diagrams of the first heating element 541 from different perspectives. The first heating element 541 may include a heating body 5411. The heating body 5411 may be made of a thermally conductive rigid material such as metal to facilitate heating of the detection card. Heating devices such as heating resistors may be disposed inside the heating body 5411.

[0673] The heating element 5411 can be placed in the first housing 51, for example, the snap-fit ​​hole 513, and snap-fitted with the first housing 51, for example, the housing body 511, so as to realize the installation of the heating element 5411 on the first housing 51.

[0674] A groove 5412 is provided on the surface of the heating body 5411 facing the second housing 57 to mate with the second housing 57. A retaining edge 5413 is provided on the edge of the heating body 5411 facing the second housing 57 so that the heating body 5411 is placed in the retaining hole 513 from the side of the first housing 51 near the second housing 57 and exposed on the side of the first housing 51 away from the second housing 57. At the same time, the retaining edge 5413 and the protruding edge 5116 engage to prevent the heating body 5411 from slipping off from the side of the first housing 51 near the electromagnetic component 52.

[0675] In some embodiments, when the heating body 5411 is located inside the snap-fit ​​hole 513, the circuit wiring that is electrically connected to the heating device inside the heating body 5411 can pass through the communication port 5117 and be electrically connected to the first circuit board 55 to realize the control of the heating device inside the heating body 5411.

[0676] Understandably, in one embodiment, the heating body 5411 may be integral with the first housing 51, such as the housing body 511.

[0677] Please see Figure 10 The second heating element 542 can be an overall ring structure. The second heating element 542 can be made of a thermally conductive rigid material such as metal, and can contain heating elements such as heating resistors. The second heating element 542 is installed in the clearance groove 518 of the housing body 511. The second heating element 542 can be fixed to the clearance groove 518 by means of screwing, plugging, snap-fit, or other connection methods. The second heating element 542 has a notch 5421 to accommodate the notch 514 and the transport assembly 60.

[0678] In some embodiments, when the second heating element 542 is located in the relief groove 518, the circuit traces that are electrically connected to the internal heating device of the second heating element 542 can pass through the connecting hole 5114a and be electrically connected to the first circuit board 55 to realize the control of the internal heating device of the second heating element 542.

[0679] Please see Figure 16 , Figure 16 for Figure 10A schematic diagram of the structure of the first circuit board 55 is shown. The first circuit board 55 can be a ring structure. Electronic components such as resistors, capacitors, and inductors are disposed on the first circuit board 55. The first circuit board 55 is installed in the receiving groove 512 of the housing body 511. The first circuit board 55 can be limited by the limiting post 5114 to prevent shaking. The first circuit board 55 can be fixed to the connecting post 5115 by means of screwing, plugging, or snap-fit ​​connection. The first circuit board 55 has a notch 551 to make way for the side wall 5111, the notch 514, and the transport assembly 60. The first circuit board 55 can be electrically connected to the heating element and the electromagnetic element 52 in the heating assembly 54 respectively, so as to control the heating element and the electromagnetic element 52 in the heating assembly 54 respectively. In one embodiment, the first circuit board 55 can be omitted if it does not share the working pressure of the control circuit board 40, and the heating element and the electromagnetic element 52 in the heating assembly 54 can be directly electrically connected to the control circuit board 40.

[0680] Please see Figure 17 and Figure 18 , Figure 17 for Figure 10 A schematic diagram of the structure of the locking component 56. Figure 18 for Figure 17 A cross-sectional view of the locking member 56 along line XVII-XVII. The locking member 56 may include a locking housing 561 fixed to the housing body 511, a linkage assembly 562 disposed inside the locking housing 561, and a locking claw 563 disposed outside the locking housing 561 and connected to the linkage assembly 562.

[0681] Specifically, the locking housing 561 is hollow inside, and retaining walls 5611 are provided on opposite sides of the opening, with the retaining walls 5611 protruding outward from the locking housing 561. A clearance hole 5612 is provided in the locking housing 561 near the retaining walls 5611. A retaining block 5613 is provided within the clearance hole 5612. The retaining block 5613 is elastically deformable and protrudes outward from the locking housing 561. When the locking member 56 is installed on the housing body 511, the end of the locking housing 561 away from the retaining walls 5611 extends from the side of the first housing 51 (e.g., the housing body 511) away from the second housing 57 into the first insertion hole 5112 or the second insertion hole 5113. The locking block 5613 undergoes elastic deformation under the pressure of the first housing 51, such as the housing body 511, causing it to pass through the insertion hole. This allows the housing body 511 to lock into the clearance hole 5612. The locking wall 5611 is located on the side of the housing body 511 away from the second housing 57 and abuts against the bottom surface of the clearance groove 518. The locking block 5613 is positioned on the side of the housing body 511 closer to the second housing 57 and abuts against the bottom surface of the receiving groove 512. Thus, under the action of the locking wall 5611 and the locking block 5613, the locking housing 561 is locked and installed in conjunction with the first housing 51, such as the housing body 511. Understandably, the locking housing 561 can also be fixed to the housing body 511 by means of screwing, insertion, snap-fitting, bonding, welding, etc., which will not be elaborated upon.

[0682] The linkage assembly 562 may include a linkage body 5621 installed inside the locking housing 561, a connector 5622 slidably connected to the linkage body 5621, an elastic member 5623 installed on the linkage body 5621 and the connector 5622 and forcing the connector 5622 to slide relative to the linkage body 5621 outward from the locking housing 561, and a linkage member 5624 provided on the linkage body 5621 for locking or unlocking the connector 5622.

[0683] The linkage body 5621 is a hollow columnar structure disposed within the locking housing 561, extending from the bottom surface of the locking housing 561 to the position of the latch 5613. In one embodiment, the linkage body 5621 may be an integral structure with the locking housing 561. In another embodiment, the linkage body 5621 may be omitted.

[0684] Connector 5622 is disposed in the linkage body 5621, and may be columnar. The outer diameter of one part of connector 5622 is larger than the outer diameter of another part of connector 5622. One end of the connector 5622 with the larger outer diameter is connected and fixed to the locking claw 563. In one embodiment, the outer diameters of connectors 5622 are the same.

[0685] The elastic element 5623 is sleeved on the smaller outer diameter portion of the connector 5622. In one embodiment, the elastic element 5623 may be a spring, sleeved around the connector 5622, with one end abutting against the linkage body 5621 or the locking housing 561, and the other end abutting against the connector 5622. It is understood that the elastic element 5623 may also be made of other elastic materials, which will not be elaborated further.

[0686] The linkage component 5624 is fixed inside the linkage body 5621 to lock or unlock the linkage component 5624. The linkage component 5624 can be an electromagnet, for example, an electromagnet electrically connected to the control circuit board 40, so that under the control of the control circuit board 40, it can attract and fix the connector 5622 at a certain position, preventing the connector 5622 from moving, thus locking the connector 5622. When unlocking the connector 5622, the linkage component 5624, under the control of the control circuit board 40, also unlocks the connector 5622 at a certain position. In one embodiment, the linkage component 5624 can also be other structures such as an electromagnet. Of course, the linkage component 5624 can also be a mechanical structure such as a wheel, ratchet, or other structure that can lock or unlock the connector 5622.

[0687] In one embodiment, the linkage 5624 may be configured as follows:

[0688] When the linkage 5624 locks the connector 5622, the connector 5622 moves into the locking housing 561 again to slide relative to the linkage body 5621, which can trigger the linkage 5624 and break the state of the linkage 5624 locking the connector 5622.

[0689] When the linkage 5624 is not locked to the connector 5622, the connector 5622 moves into the locking housing 561 to slide relative to the linkage body 5621, thereby triggering the linkage 5624 and locking the connector 5622.

[0690] When the locking member 56 is in use, with the locking claw 563 and the clamping member 53 aligned, the locking claw 563 can move towards the clamping member 53 under the drive of the first housing 51, causing the locking claw 563 to abut against the clamping member 53. The locking claw 563 is subjected to a resisting force moving into the locking housing 561, and thus moves into the locking housing 561. At the same time, it is subjected to the squeezing force of the locking housing 561, causing the locking claw 563 to close and clamp the clamping member 53, for example, between two adjacent clearance portions, or in the form of a connecting post or connecting lug, thereby achieving clamping and locking of the clamping member 53. Simultaneously, the resisting force acting on the locking claw 563 as it moves into the locking housing 561 triggers the linkage component 562, which keeps the locking claw 563 in a locked state. When the locking claw 563 remains locked, it is again subjected to a resisting force that moves into the locking housing 561. The locking claw 563 moves into the locking housing 561 again, which will trigger the linkage component 562 again. The linkage component 562 will break the locked state held by the locking claw 563, thereby unlocking it. Then, under the action of the linkage component 562, the locking claw 563 moves away from the locking housing 561, thereby causing the locking claw 563 to open and unable to clamp and lock the clamping member 53, thus releasing the clamping member 53.

[0691] In one embodiment, the locking element 56 may also be a door lock switch. In another embodiment, if the electromagnetic element 52 is present, the locking element 56 may be omitted.

[0692] Please see Figure 19 and Figure 20 , Figure 19 and Figure 20 They are respectively Figure 10 The diagram shows the structure of the second housing 57 from different perspectives. The second housing 57 may include a cover body 571 that can be fastened to the first housing 51, such as the housing body 511. The cover body 571 may be connected and fixed to the first housing 51, such as the housing body 511, by means of screwing, plugging, snapping, welding, bonding, etc., which will not be described in detail.

[0693] The cover body 571 can be made of a rigid material such as plastic or metal. The cover body 571 has a through hole 572. The through hole 572 can be positioned opposite to the receiving groove 512 to allow space for the first circuit board 55, exposing the first circuit board 55. In one embodiment, the through hole 572 can be omitted, and the cover body 571 completely covers the first housing 51, such as the housing body 511. In one embodiment, the size of the through hole 572 can be adjusted so that the through hole 572 corresponds to the portion of the notch 514 within the housing body 511 to allow space for the transport assembly 60. Additionally, the cover body 571 will cover the first circuit board 55.

[0694] The cover body 571 is provided with a notch 573. The notch 573 extends inward from the edge of the cover body 571 to communicate with the through hole 572. The notch 573 is located opposite to the notch 514 on the cover body 571, so that when the cover body 571 is fastened to the housing body 511, the notch 573 communicates with the notch 514 to make way for the transport component 60, so that the transport component 60 can slide within the notch 573.

[0695] A fixing post 574 is provided on the side of the cover body 571 facing the first housing 51. The fixing post 574 protrudes from the surface of the cover body 571. The fixing post 574 is located opposite the groove 5412 of the heating component 54 on the cover body 571, so that a spring can be fitted on the fixing post 574, such that one end of the spring abuts against the cover body 571 and the other end abuts against the heating component 54 at the groove 5412. Under the action of the spring, when the heating component 54 is subjected to force on the side of the first housing 51 away from the second housing 57, it can move relative to the first housing 51 and move towards the second housing 57, and the spring is compressed. In one embodiment, the fixing post 574 can be omitted. In one embodiment, the spring can also be replaced by other elastic elements, which will not be described in detail.

[0696] The main body 571 of the cover has a hook 575 on the side away from the first housing 51 for connection to the transport component 60. The hook 575 is connected and fixed to the main body 571 by means of screwing, plugging, snapping, welding, or bonding. In one embodiment, there may be two hooks 575, such as a first hook 5751 and a second hook 5752. The first hook 5751 and the second hook 5752 are symmetrically arranged. It can be understood that when the hooks 575 serve to connect to the transport component 60, the number and position of the hooks 575 can be set according to actual needs.

[0697] The cover body 571 is also provided with a positioning hole 576, which is located on the cover body 571 opposite to the positioning hole 517, so that when the cover body 571 is fastened to the housing body 511, the positioning hole 576 communicates with the positioning hole 517 to realize the positioning of the test card.

[0698] Please see Figure 10 and Figure 21 , Figure 21 for Figure 10 A three-dimensional structural diagram of the pressure plate 50. A first slide rail assembly 58 is disposed on the first housing 51 to achieve a sliding connection between the first housing 51 and the frame 10, such as the first guide rail 1126. The first slide rail assembly 58 may include multiple slide rails. The specific number of slide rails may be the same as the number of first guide rails 1126; in some embodiments, the number of slide rails may be less than the number of first guide rails 1126.

[0699] In one embodiment, the number of slide rails may be four, namely a first slide rail 581, a second slide rail 582, a third slide rail 583, and a fourth slide rail 584.

[0700] Please see Figure 21 and Figure 22 , Figure 22 for Figure 21 A schematic diagram of the structure of the first slide rail 581 is shown. Each slide rail, such as the first slide rail 581, may include a first slide rail mounting member 5811 disposed on the first housing 51, such as the housing body 511, and a first slide rail member 5812 mounted on the first slide rail mounting member 5811. The first slide rail member 5812 may be mounted on the first guide rail 1126 to achieve relative sliding between the first slide rail member 5812 and the first guide rail 1126.

[0701] The first slide rail mounting component 5811 can be made of rigid materials such as plastic or metal. The first slide rail mounting component 5811 can be fixed to the side of the first housing 51, for example, the main body 511 of the housing, through connection methods such as screwing, plugging, snap-fitting, welding, or bonding. The first slide rail mounting component 5811 is bent towards the cover body 571 from the side away from the detection card detection seat 30, forming a bent portion 5814. The bent portion 5814 can abut against the side of the second housing 57 away from the first housing 51. In one embodiment, bolts, screws, or other threaded structures can sequentially pass through the bent portion 5814 and the second housing 57 to connect and fix it to the first housing 51. Of course, other methods such as plugging, snap-fitting, welding, and bonding can also be used to achieve the connection and fixation relationship between the bent portion 5814, the second housing 57, and the first housing 51.

[0702] In one embodiment, a limiting plate 5813 can be provided on a slide rail, such as the first slide rail 581, to cooperate with the second limiting switch 16. For example, when the pressure plate 50 slides against the frame 10, such as the first guide rail 1126, the limiting plate 5813 can slide along the stroke of the pressure plate 50. When the limiting plate 5813 slides to a predetermined position, it can be placed in the groove of the second limiting switch 16, such as the groove of the slotted optocoupler, blocking the light transmission between the limiting light-emitting part and the limiting light-receiving part. This triggers the slotted optocoupler to generate a control signal, which is transmitted to the control circuit board 40. Under the control of the control circuit board 40, the operation of the first driving device 12, such as the driving assembly 121, is stopped, thus stopping the movement of the pressure plate 50. It can be understood that the limiting plate 5813 can also be provided on other slide rails in the first slide rail assembly 58, or at other parts of the pressure plate 50.

[0703] Please see Figure 23 , Figure 23This is a schematic diagram of the connection structure between the frame 10 and the pressure plate 50. The pressure plate 50 is mounted on the frame 10. The first slide rail member 5812 of the first slide rail 581 is mounted on the first guide rail 1126 of the third support leg 1123. Correspondingly, the first slide rail member 5812 of the second slide rail 582 is mounted on the first guide rail 1126 of the fourth support leg 1124. The first slide rail member 5812 of the third slide rail 583 is mounted on the first guide rail 1126 of the first support leg 1121. The first slide rail member 5812 of the second slide rail 582 is mounted on the first guide rail 1126 of the second support leg 1122. The first screw connection 515 is screwed to the first lead screw 1221, for example, the lead screw body 1224. The second screw connection 516 is screwed to the second lead screw 1222, for example, the lead screw body 1224. When the drive assembly 121 moves, it can drive the first lead screw 1221 and the second lead screw 1222 to move synchronously. As a result, the first lead screw 1221 and the second lead screw 1222 both rotate relative to the pressure plate 50, so that the first slide rail assembly 58 of the pressure plate 50, such as the first slide rail 5812, can slide on the first guide rail 1126, thereby realizing the position movement of the pressure plate 50, specifically, realizing the position movement of the pressure plate 50 in the vertical direction.

[0704] Baggage Components 60

[0705] Please see Figure 24 , Figure 24 for Figure 2 A schematic diagram of the structure of the transport assembly 60. The transport assembly 60 may include a sliding frame 61 disposed above the pressure plate 50 and mounted on a frame 10, such as a first guide rail 1126, and a transport component 62 mounted on the sliding frame 61. The sliding frame 61 is slidable on the frame 10, such as the first guide rail 1126. The sliding frame 61 is connected to the pressure plate 50 so that, in certain scenarios, it slides together with the pressure plate 50 on the frame 10. The transport component 62 can be used to hold a detection card. The transport component 62 is slidable relative to the sliding frame 61. The sliding direction of the transport component 62 relative to the sliding frame 61 is different from the sliding direction of the sliding frame 61 relative to the frame 10.

[0706] Understandably, when the transport assembly 60 extends, the transport piece 62 slides on the sliding frame 61 to a first position outside the rack 10, completing the extension, and a detection card is placed while the transport assembly 60 is in the extended state. Then, when the transport assembly 60 retracts, the transport piece 62 slides on the sliding frame 61 to a second position inside the rack 10, completing the retraction, and can slide between a third and a fourth position on the first guide rail 1126 while the transport assembly 60 is in the retracted state. In some embodiments, the transport assembly 60 can extend in the third position. In some embodiments, the transport assembly 60 can extend in a position between the third and fourth positions.

[0707] Please see Figure 25 , Figure 25 for Figure 24 A schematic diagram of the structure of the sliding frame 61. The sliding frame 61 may include a fixed frame 611, a second slide rail assembly 612 mounted on the fixed frame 611 and slidably connected to the frame 10, for example, the first guide rail 1126, a second guide rail 613 mounted on the fixed frame 611 for mounting the transport item 62, and a second drive device 614 for driving the transport item 62 to slide on the second guide rail 613.

[0708] Understandably, the terms "first driving device," "second driving device," and "driving device" can be interchanged in some embodiments. For example, in one embodiment, the "first driving device" in other embodiments is referred to as the "second driving device," and correspondingly, the "second driving device" in other embodiments is referred to as the "first driving device."

[0709] The fixing frame 611 can be made of rigid materials such as plastic or metal. The fixing frame 611 can be a frame structure, or it can be other shapes, which will not be described in detail. The fixing frame 611 may include a first connecting plate 6111, a second connecting plate 6112 connected to the first connecting plate 6111, a third connecting plate 6113 connected to the second connecting plate 6112 and disposed opposite to the first connecting plate 6111, and a fourth connecting plate 6114 connecting the third connecting plate 6113 and the first connecting plate 6111 and disposed opposite to the second connecting plate 6112.

[0710] In one embodiment, the first connecting plate 6111, the second connecting plate 6112, the third connecting plate 6113, and the fourth connecting plate 6114 can be arranged to form a rectangle. The extending directions of the second connecting plate 6112 and the fourth connecting plate 6114 can be consistent with the extending direction of the strip hole 1111, or they can be different.

[0711] The second slide rail assembly 612 is disposed on the fixed frame 611 and is used to achieve a sliding connection between the fixed frame 611 and the frame 10 when the second slide rail assembly 612 is slidably connected to the frame 10, such as the first guide rail 1126. The second slide rail assembly 612 may include multiple slide rails, and the specific number of slide rails may be the same as the number of first guide rails 1126. In some embodiments, the number of slide rails may be less than the number of first guide rails 1126.

[0712] In one embodiment, the number of slide rails may be four, namely a first slide rail 6121, a second slide rail 6122, a third slide rail 6123, and a fourth slide rail 6124.

[0713] Each slide rail, such as the first slide rail 6121, may include a second slide rail mounting member 6125 disposed on the fixed frame 611 and a second slide rail member 6126 mounted on the second slide rail mounting member 6125. The second slide rail member 6126 may be mounted on the first guide rail 1126 to achieve relative sliding between the second slide rail member 6126 and the frame 10, such as the first guide rail 1126.

[0714] The second slide rail mounting component 6125 can be made of rigid materials such as plastic or metal. The second slide rail mounting component 6125 can be fixed to the fixing frame 611 by means of screwing, plugging, welding, snap-fitting, or bonding. In one embodiment, the second slide rail mounting component 6125 can be omitted, and the second slide rail component 6126 can be directly set on the fixing frame 611.

[0715] When the second slide rail assembly 612 is slidably connected to the frame 10, for example, the first guide rail 1126, the second slide rail member 6126 of the slide rail, for example, the first slide rail 6121, is slidably connected to the first guide rail 1126 of the second support leg 1122. The second slide rail member 6126 of the slide rail, for example, the second slide rail 6122, is slidably connected to the first guide rail 1126 of the third support leg 1123. The second slide rail member 6126 of the slide rail, for example, the third slide rail 6123, is slidably connected to the first guide rail 1126 of the fourth support leg 1124. The second slide rail member 6126 of the slide rail, for example, the fourth slide rail 6124, is slidably connected to the first guide rail 1126 of the first support leg 1121.

[0716] In one embodiment, the first slide rail 6121 and the fourth slide rail 6124 are disposed on the side of the fourth connecting plate 6114 away from the second connecting plate 6112. The second slide rail 6122 and the third slide rail 6123 are disposed on the side of the second connecting plate 6112 away from the fourth connecting plate 6114. Of course, the installation positions of the first slide rail 6121, the second slide rail 6122, the third slide rail 6123, and the fourth slide rail 6124 on the fixing frame 611 can be adjusted according to the actual situation.

[0717] The second guide rail 613 is mounted on the fixing frame 611 for mounting the transport item 62, allowing the transport item 62 to slide on the second guide rail 613. The extension direction of the second guide rail 613 may be consistent with the extension direction of the strip hole 1111, so that the transport item 62 slides on the second guide rail 613 and also slides within the strip hole 1111. The second guide rail 613 may include a first sub-guide rail 6131 disposed on the fixing frame 611, for example, the second connecting plate 6112, and a second sub-guide rail 6132 disposed on the fixing frame 611, for example, the fourth connecting plate 6114. The extension direction of the first sub-guide rail 6131 may be consistent with the extension direction of the second sub-guide rail 6132. The first sub-guide rail 6131 and the second sub-guide rail 6132 may be fixed to the fixing frame 611 by means of screwing, snap-fitting, welding, bonding, plugging, etc. In one embodiment, the extension direction of the first sub-guide rail 6131 is horizontal. In one embodiment, when the consignment 62 slides on the first sub-guide rail 6131, it does not affect the sliding of the consignment 62 within the strip hole 1111. The extension direction of the first sub-guide rail 6131 may be different from the extension direction of the second sub-guide rail 6132.

[0718] Understandably, the terms "first guide rail," "second guide rail," and "guide rail" can be used interchangeably in some embodiments. For example, in one embodiment, the "first guide rail" in other embodiments is referred to as the "second guide rail," and correspondingly, the "second guide rail" in other embodiments is referred to as the "first guide rail."

[0719] The second drive device 614 may include a second drive member 6141 mounted on a fixed frame 611 and a lead screw 6142 connected to the second drive member 6141. The second drive member 6141 may be mounted on the fixed frame 611, for example, a first connecting plate 6111, for driving the lead screw 6142 to rotate. The second drive member 6141 may be electrically connected to a control circuit board 40 to move under the control of the control circuit board 40. The lead screw 6142 is rotatably connected to the fixed frame 611, for example, the first connecting plate 6111 or the fourth connecting plate 6114. The extension direction of the lead screw 6142 may be consistent with the extension direction of the second guide rail 613. The outer surface of the lead screw 6142 is provided with external threads. The lead screw 6142 is screwed to the transport piece 62 via an external thread, so that when the lead screw 6142 rotates, the lead screw 6142 and the transport piece 62 rotate relative to each other, and the transport piece 62 slides on the second guide rail 613 under the cooperation of the lead screw 6142 and the second guide rail 613.

[0720] The second drive component 6141 is installed on the side of the first connecting plate 6111 away from the third connecting plate 6113, and can be connected and fixed by means of screws, bolts, clips, plugs, welding, adhesive, etc. In one embodiment, the second drive component 6141 can be a motor. The output shaft of the motor can pass through the first connecting plate 6111 and be connected to the lead screw 6142. Of course, the second drive component 6141 can also be other types of power sources.

[0721] Understandably, when the number of lead screws 6142 is large enough to maintain and support the stability of the transport component 62, the second guide rail 613 can be omitted.

[0722] In some embodiments, for positioning the detection card in the consignment 62, the mounting bracket 611, for example the first connecting plate 6111, is provided with a positioning light generator 615. The positioning light generator 615 is located on the side of the first connecting plate 6111 away from the third connecting plate 6113. The positioning light generator 615 is positioned opposite to the positioning holes, such as positioning holes 576 and 517, on the pressure plate 50, so that the light emitted by the positioning light generator 615 passes through the positioning holes, such as positioning holes 576 and 517, on the pressure plate 50, and then interacts with the positioning light receiver 716 ( Figure 33 (As shown) Use the detection card on the consignment item 62 to locate it.

[0723] In one embodiment, to limit the movement of the transport item 62, a light sensor 616 can be provided on the side of the fixing frame 611, such as the second connecting plate 6112 near the fourth connecting plate 6114.

The light sensor 616 may include a light-emitting unit for emitting light and a light-receiving unit for receiving light. When the transport item 62 slides along the second guide rail 613 towards the first connecting plate 6111 and reaches a predetermined position, it can receive the light emitted by the light-emitting unit and reflect the light to the light-receiving unit. The light sensor 616 is then triggered to generate a control signal and transmit it to the control circuit board 40. The control circuit board 40 controls the transport item 62 so that it remains in the predetermined position. In one embodiment, the light sensor 616 is located on the side of the second connecting plate 6112 near the first connecting plate 6111.

[0732] The sliding seat body 631 can be made of a rigid material such as plastic or metal. The sliding seat body 631 may include a base plate 6311 and side plates 6312 surrounding the base plate 6311. A clearance hole 6311a may be provided in the center of the base plate 6311 to allow clearance for the third drive member 64. The side plates 6312 may extend from the edge of the base plate 6311 away from the pressure plate 50. The side plates 6312 may include a first side plate 6312a on which the third slide rail assembly 632 is disposed, a second side plate 6312b connected to the first side plate 6312a and located on the side of the base plate 6311 near the first connecting plate 6111, and a third side plate 6312c connected to the second side plate 6312b and symmetrically arranged with the first side plate 6312a.

[0733] The third slide rail assembly 632 is fixed to the side of the first side plate 6312a near the second connecting plate 6112, specifically by means of screwing, plugging, snap-fitting, welding, or bonding. The third slide rail assembly 632 is slidably connected to the second guide rail 613, such as the first sub-guide rail 6131, to achieve a sliding connection between the sliding seat body 631 and the sliding frame 61. The third slide rail assembly 632 may include a third slide rail mounting member 6321 disposed on the sliding seat body 631, such as the first side plate 6312a, and a third slide rail member 6322 mounted on the third slide rail mounting member 6321.

The screw connector 6333 can be sleeved on the lead screw 6142. The screw connector 6333 has an internal thread that mates with the external thread of the lead screw 6142, so that the sliding seat 63 can move in the extension direction of the lead screw 6142 under the drive of the second drive member 6141.

[0736] Understandably, the terms "first slide rail," "second slide rail," "third slide rail," "fourth slide rail," and "slide rail" can be interchanged in some embodiments. For example, in one embodiment, the "first slide rail" in other embodiments is referred to as the "second slide rail," and correspondingly, the "second slide rail" in other embodiments is referred to as the "first slide rail."

[0737] The terms "first slide rail assembly," "second slide rail assembly," "third slide rail assembly," "fourth slide rail assembly," and "slide rail assembly" can be used interchangeably in some embodiments. For example, in one embodiment, the "first slide rail assembly" in other embodiments is referred to as the "second slide rail assembly," and correspondingly, the "second slide rail assembly" in other embodiments is referred to as the "first slide rail assembly."

[0738] The terms "first slide rail mounting component," "second slide rail mounting component," "third slide rail mounting component," "fourth slide rail mounting component," and "slide rail mounting component" can be interchanged in some embodiments. For example, in one embodiment, the "first slide rail mounting component" in other embodiments is referred to as the "second slide rail mounting component," and correspondingly, the "second slide rail mounting component" in other embodiments is referred to as the "first slide rail mounting component."

[0739] The terms "first slide rail component," "second slide rail component," "third slide rail component," "fourth slide rail component," and "slide rail component" can be interchanged in some embodiments. For example, in one embodiment, the "first slide rail component" in other embodiments is referred to as the "second slide rail component," and correspondingly, the "second slide rail component" in other embodiments is referred to as the "first slide rail component."

[0740] The fourth slide rail mounting component 6331 can be made of rigid materials such as plastic or metal. The fourth slide rail mounting component 6331 can be fixed to the side plate 6312, such as the third side plate 6312c, by means of screwing, plugging, snapping, welding, or bonding. In one embodiment, the fourth slide rail mounting component 6331 can be omitted, and the fourth slide rail component 6332 can be directly mounted on the side plate 6312, such as the third side plate 6312c.

[0741] The screw connector 6333 can be disposed between the side plate 6312, for example, the third side plate 6312c and the fourth slide rail mounting component 6331.

[0742] In one embodiment, to limit the movement of the sliding seat 63, a first limiting member 634 is provided on the sliding seat 63. The first limiting member 634 can be disposed on the part of the second side plate 6312b corresponding to the light sensor 616, so that when the sliding seat 63 slides along the second guide rail 613 toward the first connecting plate 6111, when the sliding seat 63 reaches the predetermined position, it can receive the light emitted by the light-emitting unit. The first limiting member 634 reflects the light to the light-receiving unit, the light sensor 616 generates a control signal and transmits it to the control circuit board 40, and the control circuit board 40 controls the second driving member 6141, so that the sliding seat 63 is located at the predetermined position. It can be understood that the first limiting member 634 can also be disposed at other positions that can cooperate with the light sensor 616, such as on the third driving member 64.

[0743] In addition, to limit the movement of the sliding seat 63, a second limiting member (not shown) is provided on the sliding seat 63 to cooperate with the first limiting switch 15. When the sliding seat 63 moves away from the first connecting plate 6111 and reaches a predetermined position, the second limiting member can be placed in the groove of the first limiting switch 15, such as a slotted optocoupler, to block the light transmission between the limiting light-emitting part and the limiting light-receiving part. This triggers the first limiting switch 15, such as the slotted optocoupler, to generate a control signal, which is transmitted to the control circuit board 40. Under the control of the control circuit board 40, the operation of the second driving member 6141 is stopped, thereby stopping the movement of the sliding seat 63. It is understood that the second limiting member can also be provided in other positions that can cooperate with the first limiting switch 15, such as on the third driving member 64.

[0744] Understandably, the terms "first limiting member," "second limiting member," and "limiting member" can be interchanged in some embodiments. For example, in one embodiment, the "first limiting member" in other embodiments is referred to as the "second limiting member," and correspondingly, the "second limiting member" in other embodiments is referred to as the "first limiting member."

[0745] Please refer to it again. Figure 26 and Figure 27The third drive member 64 is mounted on the sliding seat 63, for example, the base plate 6311. The side plate 6312 surrounds the third drive member 64. Specifically, the third drive member 64 can be connected and fixed to the sliding seat 63 by means of screwing, plugging, snapping, welding, or bonding. Part of the structure of the third drive member 64, such as the output shaft, can pass through the relief hole 6311a and be connected and fixed to the bracket 65. In one embodiment, the third drive member 64 can be a motor. The output shaft of the motor can pass through the relief hole 6311a and be connected to the bracket 65.

[0746] Understandably, the terms "first driving element," "second driving element," "third driving element," and "driving element" can be interchanged in some embodiments. For example, in one embodiment, the "first driving element" in other embodiments is referred to as the "second driving element," and correspondingly, the "second driving element" in other embodiments is referred to as the "first driving element."

[0747] Card holder 65 is positioned below sliding base 63 and is connected and fixed to third drive member 64.

[0748] Please see Figure 29 and Figure 30 , Figure 29 for Figure 26 A schematic diagram of the connection between the third drive component 64 and the card holder 65. Figure 30 for Figure 2 A schematic diagram showing the connection between the third drive member 64, the card holder 65, and the clamping member 53. The card holder 65 may include a card holder body 651. The card holder body 651 may be made of a rigid material such as plastic or metal. The card holder body 651 is a rotating body, and the axis of the rotating body is coaxially arranged with the output shaft of the third drive member 64. In one embodiment, the card holder body 651 is a circular disc structure.

[0749] The card tray body 651 has a raised rib 652 on the side near the third drive member 64. The raised rib 652 is arranged radiating outward from the part where the card tray body 651 is connected to the third drive member 64. The raised rib 652 is evenly distributed around the part where the card tray body 651 is connected to the third drive member 64.

[0750] Two adjacent ribs 652 and the card holder body 651 form a recess 653 for placing a detection card. The number of recesses 653 can be the same as the number of heating components 54. Of course, the number of recesses 653 can also be less than the number of heating components 54. In one embodiment, the number of recesses 653 can be 6, and the specific number of recesses 653 can be adjusted according to the actual situation.

[0751] The card tray body 651 has a second locking portion 654 within a recess 653 for securing the detection card. The second locking portion 654 is located near the edge of the card tray body 651. In one embodiment, the second locking portion 654 is a groove or a protrusion. The card tray body 651 has a receiving hole 655 within the recess 653 to accommodate the detection card. In one embodiment, the recess 653 is a groove, the depth of which may be the same as the thickness of the detection card, so that when the detection card is placed in the recess 653, the surface of the detection card is flush with the surface of the protrusion 652 away from the card tray body 651.

[0752] In one embodiment, to connect the card holder body 651 to the clamping member 53, a third locking portion 6521 may be provided on the rib 652 so that the third locking portion 6521 engages with the clamping member 53. In one embodiment, the third locking portion 6521 is a protrusion, so that the protrusion is placed in the first locking portion 5314 of the clamping member 53, for example, a connecting hole, and engages with the clamping member 53. In one embodiment, the first locking portion 5314 may be provided on the rib 652, and the third locking portion 6521 may be provided on the clamping member 53. In one embodiment, the engaging relationship between the third locking portion 6521 and the clamping member 53 can also be replaced by other structures such as grooves and protrusions, insertion structures, snap-fit ​​structures, etc. In one embodiment, to further enhance the fit between the card holder body 651 and the clamping member 53, a permanent magnet or electromagnet or other magnetic force connector can be provided inside the card holder body 651 and / or the rib 652, so as to use magnetic force to attract the clamping member 53, enhance the fit between the third locking part 6521 and the clamping member 53, and make the clamping member 53 abut against the surface of the detection card to avoid unstable installation of the detection card.

[0753] In one embodiment, to achieve positioning of the detection card, a positioning hole 6522 may be formed on the protruding rib 652. When the card tray body 651 rotates to a predetermined position, the positioning hole 6522 is opposite to the positioning holes 517 and 576, so that when the light emitted by the positioning light generator 615 passes through the positioning holes 517, 576 and 6522, it is confirmed that the detection card on the card tray body 651 is in the predetermined position. If, when the card tray body 651 has not rotated to the predetermined position, the light emitted by the positioning light generator 615 passes through the positioning holes 517 and 576 but not through the positioning hole 6522, it is confirmed that the detection card on the card tray body 651 is not in the predetermined position.

[0754] In one embodiment, the card tray body 651 is provided with a first positioning element 656 (e.g., ...) on the side away from the third driving member 64. Figure 31As shown, this is to position the test card when it is transported to the test card testing seat 30, so that the test card is placed in a predetermined position for testing. In one embodiment, the first positioning member 656 is a positioning block that extends away from the card holder body 651, and the cross-sectional area perpendicular to the extension direction gradually changes and decreases. In one embodiment, the positioning block may be conical.

[0755] Understandably, when the card holder body 651 transports the test card to the test card test seat 30, the transport piece 62 can be located in the fourth position.

[0756] Understandably, the terms "first position," "second position," "third position," "fourth position," and "position" can be interchanged in some embodiments. For example, in one embodiment, the "first position" in other embodiments is referred to as the "second position," and correspondingly, the "second position" in other embodiments is referred to as the "first position."

[0757] Please see Figure 31 and Figure 32 Each of these is a separate application. Figure 2 Schematic diagrams of the connection structure between the pressure plate 50 and the transport assembly 60 from different perspectives. When connecting the pressure plate 50 and the transport assembly 60, first assemble the components of the transport assembly 60, excluding the card holder 65, together. Then, place the sliding frame 61 of the transport assembly 60 above the pressure plate 50. The first slide rail 6121 of the sliding frame 61 is positioned opposite to the fourth slide rail 584 of the pressure plate 50 so that they are mounted together on the first guide rail 1126 of the second leg 1122 of the frame 10. The second slide rail 6122 of the sliding frame 61 is positioned opposite to the first slide rail 581 of the pressure plate 50 so that they are mounted together on the first guide rail 1126 of the third leg 1123 of the frame 10. The third slide rail 6123 of the sliding frame 61 is positioned opposite to the second slide rail 582 of the pressure plate 50 so that they are mounted together on the first guide rail 1126 of the fourth leg 1124 of the frame 10. The fourth slide rail 6124 in the sliding frame 61 is arranged opposite to the third slide rail 583 of the pressure plate 50 so that they can be installed together on the first guide rail 1126 of the first support leg 1121 of the frame 10.

[0758] Understandably, the pressure plate 50 and the transport assembly 60 can also be installed on different first guide rails 1126. Of course, it is also possible to install only the pressure plate 50 or the transport assembly 60 on some of the first guide rails 1126.

[0759] Next, the tray 65 of the transport component 62 in the transport assembly 60 is placed on the side of the pressure plate 50 away from the sliding frame 61, so that the clamping member 53 is located between the first housing 51 and the tray 65. The output shaft of the third drive member 64 of the transport component 62 in the transport assembly 60 passes through the notch of the pressure plate 50 and is connected and fixed to the tray 65.

[0760] The first lug 5751 of the pressure plate 50 is opposite to and connected to the first traction member 6171 in the transport assembly 60. The second lug 5752 of the pressure plate 50 is opposite to and connected to the second traction member 6172 in the transport assembly 60. Specifically, one end of the elastic member 6172b of the first traction member 6171 is connected to the suspension member 6172a of the first traction member 6171, and the other end of the elastic member 6172b of the first traction member 6171 is connected to the first lug 5751 of the pressure plate 50. One end of the elastic member 6172b of the second traction member 6172 is connected to the suspension member 6172a of the second traction member 6172, and the other end of the elastic member 6172b of the second traction member 6172 is connected to the first lug 5751 of the pressure plate 50.

The card detection holder 30 may include a support frame 70 fixedly connected to the frame 10, a support base 80 mounted on the support frame 70, and a detection assembly 90 mounted on the support frame 70 and the support base 80. The support base 80 is located below the pressure plate 50 to facilitate carrying the card from the card transport carrier 20, such as the transport assembly 60. The detection assembly 90 is electrically connected to the control circuit board 40. When a card is placed on the support base 80, the detection assembly 90 uses excitation light to perform a series of detection processes on the card to generate a detection signal, which is then transmitted to the control circuit board 40.

[0763] Support frame 70

[0764] Please see Figure 33 The support frame 70 has an overall frame structure and can be located at the bottom of the frame 10. The support frame 70 may include a base 71 disposed at the bottom of the frame 10 and fixedly connected to the frame 10, and a fixing seat 72 mounted on the top of the base 71.

[0767] The base body 711 has a plurality of isolation grooves 713 evenly distributed around the fixing groove 712 to cooperate with the detection component 90. A fixing part 714 is formed between two adjacent isolation grooves 713 to cooperate with the detection component 90. The arrangement of multiple isolation grooves 713 can reduce the contact area between the detection component 90 and the base body 711. In one embodiment, the isolation grooves 713 may be omitted.

[0768] The top of the base body 711 is provided with a support portion 715 for supporting the support base 80. The support portion 715 can be connected and fixed to the base body 711 by means of plugging, screwing, welding, bonding, snap-fitting, etc. In one embodiment, the support portion 715 can be a rod-shaped structure; of course, the support portion 715 can also be other structures. In one embodiment, if there is another structure supporting the support base 80, the support portion 715 can be omitted.

[0769] A positioning light receiver 716 is disposed on the top of the base body 711, opposite to the positioning light generator 615, to receive the light emitted by the positioning light generator 615, thereby achieving positioning of the test card. The positioning light receiver 716 can be electrically connected to the control circuit board 40 so that after receiving the light, the positioning light receiver 716 generates a signal and transmits it to the control circuit board 40, so that the molecular diagnostic device 100 confirms that the test card has reached the predetermined position. In some embodiments, the mounting positions of the positioning light generator 615 and the positioning light receiver 716 can be interchanged.

[0770] The mounting base 72 may include a mounting seat 721 placed within the mounting groove 712. The mounting seat 721 may be made of rigid materials such as plastic or metal.

In one embodiment, the shape of the second positioning member 813, for example, a positioning block, can match the shape of the first positioning member 656, for example, a positioning groove. Understandably, the positioning relationship between the support body 81 and the card holder 65 is not limited to the relationship between the second positioning element 813 and the first positioning element 656. It can also be a relationship of magnetic force between magnets, magnetic force between electromagnets, etc. Of course, it can also be other relationships, which will not be elaborated here.

[0777] Understandably, the terms "first positioning element," "second positioning element," and "positioning element" can be interchanged in some embodiments. For example, in one embodiment, the "first positioning element" in other embodiments is referred to as the "second positioning element," and correspondingly, the "second positioning element" in other embodiments is referred to as the "first positioning element."

[0778] The support body 81 has a positioning hole 814 in the placement groove 811. The positioning hole 814 can be arranged opposite to the positioning holes 517, 576 and 6522, so that the light emitted by the positioning light generator 615 passes through the positioning holes 814, 517, 576 and 6522 and is received by the positioning light receiver 716, thereby realizing the positioning of the detection card.

[0779] The support body 81 has multiple extension slots 815 evenly distributed around the placement slot 811.

An extension 8222 extends from the side of the detection seat body 8221 toward the receiving hole 817 so that the extension 8222 extends into the receiving hole 817. The extension 8222 is flush with the surface of the mounting table 816 on the side of the support body 81 where the mounting table 816 is provided, thereby improving the appearance of the support seat 80.

[0785] The extension 8222 is provided with a detection groove 8223 so that a portion of the structure of the detection card can be placed in the detection groove 8223 on one side of the support body 81 where the assembly table 816 is provided.

[0795] In one embodiment, the excitation fiber channel 8225 is tilted from the detection slot 8223 toward the sample application cavity assembly 83. The extension direction of the excitation fiber channel 8225 can form an angle with the extension direction of the detection slot 8223, and the angle can be 45°. The receiving fiber channel 8227 is tilted from the detection slot 8223 toward the side away from the sample application cavity assembly 83. The extension direction of the receiving fiber channel 8227 can form an angle with the extension direction of the detection slot 8223, and the angle can be 75°. That is, the extension direction of the receiving fiber channel 8227 can form an angle with the extension direction of the excitation fiber channel 8225, and the angle can be 120°. The signal-to-noise ratio of the photodetector 821 can reach 80dB or higher.

[0796] In one embodiment, the extension direction of the excitation fiber channel 8225 may be consistent with the extension direction of the detection slot 8223. The receiving fiber channel 8227 is inclined from the detection slot 8223 toward the side away from the sample application cavity assembly 83, and the extension direction of the receiving fiber channel 8227 may form an angle with the extension direction of the detection slot 8223, and the degree of the angle may be 60°.

[0797] The detection base body 8221 has a heating element receiving groove 8229a on one side where the excitation fiber optic channel 8225 is located, for housing heating devices such as heating resistors. The detection base body 8221 can heat the detection card through the heating device.

The middle part of the clamping body 8231 can abut against the side of the detection base 822, such as the detection base body 8221, where the excitation fiber channel 8225 is located. The clamping body 8231 has fixing parts 8232 at both ends for installation and fixing to the mounting platforms 819 on both sides of the detection base 822, such as the detection base body 8221. The fixing can be achieved by insertion, snap-fit, welding, or bonding. Multiple clamping holes 8233 are arranged along the edge of the middle part of the clamping body 8231 to allow space for the excitation fiber 8226. The clamping body 8231 forms clamping teeth 8234 between adjacent clamping holes 8233. The clamping body 8231 abuts against the detection seat 822. For example, the detection seat body 8221 has an excitation fiber channel 8225 on one side, so that the excitation fiber connector 8226b is secured in the excitation fiber channel 8225 by two adjacent clamping teeth 8234, and the excitation fiber body 8226a is located between the two adjacent clamping teeth 8234. This achieves the fixation of the optical detection element 821.

[0801] In one embodiment, in order to make way for the heating element receiving groove 8229a, the clamping body 8231 is provided with a through hole 8235 at a position opposite to the heating element receiving groove 8229a, so that the heating element can extend into the heating element receiving groove 8229a through the through hole 8235.

In one embodiment, when the support plate 724 is omitted, the tray 831 can be directly fixed to the first locking plate 722 and the second locking plate 723. In one embodiment, when the support plate 724 is omitted, the tray 831 can be fixed to the support part 715.

[0804] The support assembly 832 may include a sleeve post 8321 disposed on the side of the tray 831 away from the support plate 724 and a spring 8322 sleeved on the sleeve post 8321. One end of the spring 8322 abuts against the tray 831, and the other end abuts against the sample dispensing chamber mounting seat 833, for adjusting the distance between the sample dispensing chamber mounting seat 833 and the tray 831.

In one embodiment, the socket groove 8333 may be omitted.

[0807] The mounting body 8331 has a snap-fit ​​edge 8334 on the side facing the support component 832, so that the mounting body 8331 extends into the locking hole 812 from the side of the support body 81 facing the support component 832, thus preventing the mounting body 8331 from slipping off the support body 81 on the side of the support body 81 away from the support component 832.

[0808] The mounting base body 8331 has a heating element receiving groove 8335 to accommodate heating devices such as heating resistors, allowing the mounting base body 8331 to heat the test card. The heating device can be electrically connected to the second circuit board 84 to heat under the control of the second circuit board 84. In one embodiment, the heating element receiving groove 8335 is located between the sleeve groove 8333 and the sample loading chamber placement groove 8332.

[0809] To better heat the test card and prevent condensation of heated water vapor from affecting the testing process, thereby improving testing accuracy, the mounting base body 8331 has an abutment portion 8336 on one edge of the sample loading chamber placement groove 8332 to abut against the test card. In one embodiment, the abutment portion 8336 can also be used to position the test card.

In one embodiment, the second circuit board 84 can also be directly fixed to the sample filling chamber assembly 83, such as the tray 831.

[0812] Understandably, the terms "first circuit board," "second circuit board," and "circuit board" can be used interchangeably in some embodiments. For example, in one embodiment, the "first circuit board" in other embodiments is referred to as the "second circuit board," and correspondingly, the "second circuit board" in other embodiments is referred to as the "first circuit board."

[0827] The first lens module 915 is installed in the first sub-receiving cavity 9131a. Its optical axis may be the same as that of the light source 914, so that the excitation light emitted by the light source 914 can pass through, thereby reducing the beam size and focal length of the excitation light, and thus allowing the excitation light to be better coupled into the excitation fiber 917.

[0828] In one embodiment, the lenses, such as the first lens 9151 and the second lens 9152, are both positive lenses with a positive focal length. Specifically, the lenses, such as the first lens 9151 and the second lens 9152, can be plano-convex lenses. A plano-convex lens is a type of positive lens that primarily functions in optical systems for beam expansion, imaging, beam collimation, focusing and collimation, and beam collimation of point light sources. In a plano-convex lens, one of the incident surface and the exit surface is convex, and the other is planar.

[0829] The first lens 9151 has a flat incident surface and a convex exit surface. The second lens 9152 has a convex incident surface and a flat exit surface. The incident surface of the first lens 9151 is positioned opposite to the light source 914. The incident surface of the second lens 9152 is positioned opposite to the exit surface of the first lens 9151. The exit surface of the second lens 9152 is positioned opposite to the functional diaphragm assembly 916.

[0830] The first retaining ring 9153 can be sleeved around the first lens 9151 and the second lens 9152 to fix the first lens 9151 and the second lens 9152. When the first lens module 915 is placed in the first sub-receiving cavity 9131a, the side of the first retaining ring 9153 facing the light source 914 abuts against the front housing 9131, such as the front housing body 9133, and the side of the first retaining ring 9153 away from the light source 914 abuts against the rear housing 9132, such as the rear housing body 9135, to fix the first lens module 915 with the front housing 9131 and the rear housing 9132.

[0831] Understandably, in some embodiments, the first lens module 915 may also include other types of lenses, such as convex lenses, concave lenses, etc., which will not be elaborated further. The arrangement of the first lens 9151 and the second lens 9152 inside the first lens module 915 is not limited to the above-mentioned methods, and may also be in other ways. For example, the first lens 9151 and the second lens 9152 may be directly fixed to the front housing 9131, such as the front housing body 9133, by means of bonding, plugging, snapping, screwing, etc.

[0832] The functional diaphragm assembly 916 is used for functions such as filtering stray light and adjusting the excitation light. The functional diaphragm assembly 916 may include a filter 9161, a light homogenizer 9162, and a second retaining ring 9163 disposed in the second sub-receiving cavity 9132a.

[0833] The filter 9161 is used to receive the excitation light transmitted through the first lens module 915, such as the second lens 9152, to filter out stray light in the excitation light. The filter 9161 is also called a fluorescence filter. Fluorescence filters are key optical components used in life science instruments and biomedicine. Their main function is to select and separate the characteristic wavelengths of the excitation light and emission fluorescence of substances in biological and medical fluorescence testing and analysis systems, which are then observed through a fluorescence microscope. In one embodiment, the filter 9161 can be an excitation filter. An excitation filter, also called a fluorescence excitation filter (Exciting Filter, Exciter Filter, Excitation Filter), refers to a filter that allows only light of the wavelength that excites fluorescence to pass through in a fluorescence microscope or fluorescence imaging system. Of course, some systems now directly use laser light (i.e., the light source 914 can emit laser light) as the excitation light.

[0834] The side of filter 9161 furthest from the first lens module 915 abuts against the rear housing 9132, such as the rear housing body 9135. The side of filter 9161 closest to the first lens module 915, such as the second lens 9152, abuts against the second retaining ring 9163, thereby achieving the installation and fixation of filter 9161 to the rear housing 9132. Of course, other methods can also be used to fix filter 9161 to the rear housing 9132, such as the rear housing body 9135, for example, by adhesive, insertion, snap-fit, screwing, etc.

[0835] In one embodiment, filter 9161 may be an excitation filter. Specifically, filter 9161 may be an excitation filter with an excitation wavelength of 450-475 nm.

[0836] The homogenizer 9162 is used to receive the excitation light after passing through the filter 9161. The homogenizer 9162 is also called a homogenizing mirror, diffuser, or homogenizer, and is used to convert the excitation light into a uniform light spot of arbitrary shape.

[0837] The light homogenizer 9162 is used to receive the excitation light transmitted through the filter 9161. The side of the light homogenizer 9162 closest to the filter 9161 abuts against the filter 9161, while the side of the light homogenizer 9162 furthest from the filter 9161 abuts against the rear housing 9132, such as the rear housing cover plate 9136, to secure the light homogenizer 9162. Alternatively, other methods can be used to secure the light homogenizer 9162 to the rear housing 9132, such as adhesive bonding, insertion, snap-fitting, or screwing.

[0838] One end of the excitation fiber 917 can extend into the rear housing 9132, for example, into the second receiving hole 9136a, so that the excitation light transmitted through the light homogenizer 9162 is coupled into the excitation fiber 917. Of course, the excitation fiber 917 can also extend into the rear housing 9132, for example, into the second sub-receiving cavity 9132a.

[0839] The other end of the excitation fiber 917 can be coupled to at least one excitation fiber 8226, so that multiple photodetectors 821 can be detected using the same excitation light, reducing detection errors caused by different excitation light. In one embodiment, there are six photodetectors 821, and the excitation fiber 917 of the first light generator 911 can be coupled to the excitation fibers 8226 of three photodetectors 821. The excitation fiber 917 of the second light generator 912 can be coupled to the excitation fibers 8226 of three photodetectors 821.

[0840] In one embodiment, the diameter of the excitation fiber 917 is approximately 2.5 mm. Specifically, it can be 2.5 mm.

[0841] Please see Figure 43 , Figure 43 for Figure 33An exploded view of the light receiving assembly 92. The light receiving assembly 92 may include a light receiver 921 electrically connected to the control circuit board 40, an optical path assembly 922 for optical path connection with the detection cavity assembly 82, a first washer 923 disposed on the light receiver 921 for fixing the optical path assembly 922, a second washer 924 disposed on the first washer 923 for fixing the optical path assembly 922, and a clamping assembly 925 disposed on the second washer 924 for fixing the optical path assembly 922. Fluorescence is transmitted to the light receiver 921 through the optical path assembly 922. The light receiver 921 generates a detection signal and transmits the detection signal to the control circuit board 40.

[0842] Please see Figure 44 , Figure 44 for Figure 33 A structural diagram of the light receiver 921. The light receiver 921 may include a ring-shaped fixed plate 9211 with circuit traces, a second electrical interface 9212 disposed on the fixed plate 9211 and electrically connected to the circuit traces, and light sensors 9213 evenly distributed on the fixed plate 9211 and electrically connected to the circuit traces. The light receiver 921 can be used to receive fluorescence. The light receiver 921 is electrically connected to the control circuit board 40 through the second electrical interface 9212 to transmit the detection signal generated by fluorescence triggering to the control circuit board 40.

[0843] The fixing plate 9211 can be installed on the support frame 70, such as the base body 711, at the isolation groove 713 and the fixing part 714. The fixing plate 9211 can be spaced apart from the base body 711 at the isolation groove 713. Of course, the fixing plate 9211 can also extend into the isolation groove 713 to form a snap-fit ​​structure with the base body 711. The fixing plate 9211 can be connected and fixed to the base body 711 at the fixing part 714 by means of screwing, snap-fitting, plugging, bonding, welding, etc. The fixing plate 9211 can surround the fixing groove 712. In one embodiment, the size of the fixing plate 9211 can be similar to or even the same as the size of the support base 80, such as the support base body 81, so that the receiving optical fiber channel 8227 of the support base 80, such as the detection cavity assembly 82, is located above the optical sensor 9213, or even directly above the optical sensor 9213, reducing the difficulty of arranging the receiving optical fiber 8228.

[0844] In one embodiment, the light sensor 9213 is a photodiode.

[0845] Please see Figure 43 The optical path component 922 may include at least one sub-optical path component 9221. In one embodiment, the number of sub-optical path components 9221 may be the same as the number of optical sensors 9213 in the optical receiver 921, so that the sub-optical path components 9221 correspond one-to-one with the optical sensors 9213.

[0846] Please see Figure 45 and Figure 46 , Figure 45 for Figure 43 A schematic diagram of the structure of the neutron optical path component 9221. Figure 46 for Figure 45 Cross-sectional view of the neutron optical path assembly. The neutron optical path assembly 9221 may include a second lens module 9222 for transmitting fluorescence to the light sensor 9213 and a receiving optical fiber 9223 for transmitting fluorescence to the second lens module 9222.

[0847] The second lens module 9222 may include a third lens 9224 installed in the first washer 923, a third retaining ring 9225 for fixing the third lens 9224 in the first washer 923, a fourth retaining ring 9226 installed in the second washer 924, and a fourth lens 9227 fixed in the second washer 924 by the fourth retaining ring 9226.

[0848] Understandably, the terms "first lens," "second lens," "third lens," "fourth lens," and "lens" can be used interchangeably in some embodiments. For example, in one embodiment, the "first lens" in other embodiments is referred to as the "second lens," and correspondingly, the "second lens" in other embodiments is referred to as the "first lens."

[0849] In one embodiment, the lenses, such as the third lens 9224 and the fourth lens 9227, are both positive lenses with a positive focal length. Specifically, the lenses, such as the third lens 9224 and the fourth lens 9227, can be plano-convex lenses. A plano-convex lens is a type of positive lens that primarily functions in optical systems for beam expansion, imaging, beam collimation, focusing and collimation, and beam collimation of point light sources. One of the incident and exit surfaces of a plano-convex lens is convex, and the other is planar.

[0850] The third lens 9224 has a convex incident surface and a flat exit surface. The fourth lens 9227 has a flat incident surface and a convex exit surface. The incident surfaces of the third lens 9224 and the exit surfaces of the fourth lens 9227 are positioned opposite each other. The exit surface of the third lens 9224 is positioned opposite to the optical sensor 9213. The incident surface of the fourth lens 9227 is positioned opposite to the receiving optical fiber 9223.

[0851] In one embodiment, an emission filter (also known as an emission filter, barrier filter, or emitter) may be disposed between the third lens 9224 and the fourth lens 9227. An emission filter is a filter used to select and transmit the fluorescence emitted by the substance being detected. It blocks light from emitting any light other than the autofluorescence of the substance being detected. Typically, the wavelength of the emitted light is longer than the wavelength of the excitation light. Narrow-band filters, bandpass filters, or long-pass filters can be selected as emission filters.

[0852] In one embodiment, the emission filter may specifically be an excitation filter with an EM522-645 emission wavelength of 522-645nm.

[0853] The third retaining ring 9225 is disposed on the incident surface side of the third lens 9224 to press the third lens 9224 against the first washer 923, thereby fixing the third lens 9224.

[0854] The fourth retaining ring 9226 is disposed on the exit surface side of the fourth lens 9227 to press the fourth lens 9227 against the second washer 924, thereby fixing the fourth lens 9227.

[0855] Understandably, the terms "first locking ring," "second locking ring," "third locking ring," "fourth locking ring," and "locking ring" can be interchanged in some embodiments. For example, in one embodiment, the "first locking ring" in other embodiments is referred to as the "second locking ring," and correspondingly, the "second locking ring" in other embodiments is referred to as the "first locking ring."

[0856] Understandably, in some embodiments, the second lens module 9222 may also include other types of lenses, such as convex lenses, concave lenses, and other functional films, such as light-diffusing films and filters, which will not be elaborated further. The arrangement of the third lens 9224 and the fourth lens 9227 is not limited to those mentioned above; other methods are also possible. For example, the third lens 9224 can be directly fixed to the first washer 923 by bonding, insertion, snap-fitting, screwing, etc. Similarly, the fourth lens 9227 can be directly fixed to the second washer 924 by bonding, insertion, snap-fitting, screwing, etc.

[0857] In one embodiment, the second lens module 9222 provides an emission filter between the third lens 9224 and the fourth lens 9227. An emission filter is a filter used to select and transmit the fluorescence emitted by the substance being detected. It blocks light from other ranges except for the autofluorescence of the substance being detected. Typically, the wavelength of the emitted light is longer than the wavelength of the excitation light. Bandpass filters, long-pass filters, or similar filters can be selected as emission filters.

[0858] In one embodiment, the emission filter can be placed between the first washer 923 and the second washer 924 to achieve a fixed connection of the emission filter.

[0859] The receiving optical fiber 9223 may include a receiving optical fiber body 9223a and a receiving optical fiber connector 9223b disposed at the end of the receiving optical fiber body 9223a. The receiving optical fiber connector 9223b is positioned within a first washer 923 and / or a second washer 924 to transmit fluorescence to the second lens module 9222, such as a fourth lens 9227. A fixing position is formed at the connection between the receiving optical fiber body 9223a and the receiving optical fiber connector 9223b to cooperate with the clamping assembly 925. In one embodiment, the diameter of the receiving optical fiber 9223, such as the receiving optical fiber body 9223a, is approximately 2.5 mm. Specifically, it may be 2.5 mm.

[0860] One end of the receiving optical fiber 9223 can be connected to a receiving optical fiber 8228 so that fluorescence is transmitted to the optical sensor 9213 through the receiving optical fiber 8228 and the receiving optical fiber 9223.

The side of the third lens 9224 away from the photosensor 9213 can abut against the third retaining ring 9225, so that the third retaining ring 9225 and the first washer 923 cooperate to fix the third lens 9224.

[0865] The first filling hole 9232 can be disposed opposite to the light sensor 9213 so that the light sensor 9213 can receive fluorescence. In one embodiment, the light sensor 9213 can extend into the first filling hole 9232. The exit surface of the third lens 9224 can abut against the first washer 923. The third retaining ring 9225 can be fixedly connected to the first washer 923 to achieve connection and fixation of the third lens 9224.

[0866] Please see Figure 48 , Figure 48 for Figure 43 A schematic diagram of the structure of the second washer 924 is shown. The second washer 924 can be made of rigid materials such as metal or plastic. The second washer 924 can be ring-shaped, specifically matching the shape of the first washer 923, so that the first washer 923 and the second washer 924 can be stacked. The second washer 924 is provided with a clearance notch 9241 opposite to the clearance notch 9231 to allow space for the second electrical interface 9212. When the second washer 924, the first washer 923 and the fixing plate 9211 are stacked, the second electrical interface 9212 can be placed within the clearance notches 9231 and 9241.

[0867] The first washer 923 can be fixed together with the second washer 924 by means of screwing, welding, snap-fitting, or bonding. In one embodiment, the first washer 923 and the second washer 924 can be an integral structure.

The second filling holes 9242 can be positioned opposite to the first filling holes 9232 so that the photosensor 9213 can receive fluorescence. The side of the fourth lens 9227 facing the photosensor 9213 can abut against the fourth retaining ring 9226. The side of the fourth lens 9227 away from the photosensor 9213 can abut against the second washer 924, thereby achieving a secure connection between the fourth retaining ring 9226 and the second washer 924 for the fourth lens 9227. The receiving fiber optic connector 9223b of the receiving fiber optic 9223 can extend from the second washer 924 into the second filling holes 9242.

[0869] Understandably, the first washer 923 and the second washer 924 can form a component housing, and the first filling hole 9232 and the second filling hole 9242 communicate to form a filling hole.

This achieves a fixed connection between the receiving fiber optic 9223 and the second washer 924.

[0893] Test card 93

[0894] The following describes a test card that can be used in the molecular diagnostic device 100 in the above embodiments to perform testing on the sample loaded on the test card and further process it to form diagnostic data.

[0895] Please see Figure 50 , Figure 50 This is a schematic diagram of the structure of a test card in one embodiment of this application. The test card 93 is also known as a molecular diagnostic centrifugation test card or a test card. The test card 93 may include a body 94 having a sample dispensing chamber, a flow channel, a waste liquid chamber, an isolation chamber and a test chamber, an isolation layer 95 covering one side of the body 94, and a cover 96 covering the sample dispensing chamber of the body 94.

[0896] Please refer to the following: Figure 50 , Figure 51 and Figure 52 , Figure 51 for Figure 50 A cross-sectional view of the LL line along the 93 detection card in China. Figure 52 for Figure 50A three-dimensional structural diagram of the detection card 93. The body 94 is made of rigid materials such as plastic. Specifically, the body 94 can be made of materials such as ABS (Acrylonitrile Butadiene Styrene plastic), PDMS (Polydimethylsiloxane), PC (Polycarbonate), PMMA (Polymethyl methacrylate), PS (General purpose polystyrene), PP (Polypropylene), COC (copolymers of cycloolefin), or COP (Cyclo olefin polymer), and can be processed by injection molding, CNC machine tool processing, or 3D printing.

[0897] The main body 94 can be a plate-like structure. It is generally fan-shaped, but can specifically be a fan ring, fan blade, or disc shape. For example, the main body 94 can be a fan shape formed by connecting two straight sides and one curved side end to end. Another example is a fan ring formed by connecting one straight side, one outer curved side, one straight side, and one inner curved side end to end. Of course, the main body 94 can also be other shapes, which will not be elaborated upon.

[0898] In one embodiment, the included angle between the two straight sides of the fan-shaped structure of the body 94 can be 40°-60°, the diameter of the inner arc side can be 10mm-100mm, and the diameter of the outer arc side can be 100mm-200mm. At least six detection cards 93 with this size structure can be arranged in the detection plane of the molecular diagnostic device 100, forming a circular surface. This allows at least six detection cards 93 to be detected simultaneously, improving overall detection efficiency and meeting large-scale detection needs.

[0899] A mounting portion 941 is provided on the body 94, protruding from the center of the outer arc edge or the inner arc edge and away from the isolation layer 95. A sample dispensing chamber 9411 is recessed on the body 94 near the isolation layer 95, opposite to the mounting portion 941, for adding samples. The sample dispensing chamber 9411 is mainly used for sample (liquid sample) pretreatment, which may include one or more methods, such as chemical treatment, heat treatment, enzyme treatment, and physical separation. In some embodiments, the volume of the sample dispensing chamber 9411 is approximately 200-2000 μL. Dry reagents can be pre-filled in the sample dispensing chamber 9411, which can be air-dried / baked in situ or added as lyophilized reagents.

[0900] The main body 94 has a fourth locking portion 942 on the side away from the isolation layer 95 and near the outer arc edge, to cooperate with the transport component 60, such as the second locking portion 654. In one embodiment, the fourth locking portion 942 may be a protrusion. It is understood that the second locking portion 654 and the fourth locking portion 942 may be interchanged, and the second locking portion 654 and the fourth locking portion 942 may also be locked together in other ways.

[0901] Understandably, the names "first locking part," "second locking part," "third locking part," "fourth locking part," and "locking part" can be interchanged in some embodiments. For example, in one embodiment, the "first locking part" in other embodiments is referred to as the "second locking part," and correspondingly, the "second locking part" in other embodiments is referred to as the "first locking part."

[0902] The main body 94 has a first limiting part 943 bent at the edge of one straight side near the outer arc edge, away from the isolation layer 95, and a second limiting part 944 protruding at the edge of the other straight side near the outer arc edge, away from the isolation layer 95. The first limiting part 943 and the second limiting part 944 cooperate to fix the detection card 93, so as to facilitate the centrifugation of the detection card 93. A waste liquid chamber 9441 is recessed on the side of the main body 94 near the isolation layer 95, opposite to the second limiting part 944. On the side of the main body 94 away from the isolation layer 95, and between the first limiting part 943 and the second limiting part 944, a plurality of plug-in part groups are evenly distributed along the extension direction of the outer arc edge. Each plug-in part group may include a first plug-in part 945 and a second plug-in part 946. The line connecting the first plug-in part 945 and the second plug-in part 946 may pass through the center of the outer arc edge. The first connector 945 is positioned between the mounting portion 941 and the second connector 946. The first connector 945 and the second connector 946 can be configured to cooperate with the detection card holder 30, for example, the isolation groove 8224 or the detection groove 8223.

[0903] The main body 94 has an recessed isolation cavity 9451 on the side near the isolation layer 95 and opposite to the first insertion portion 945. The isolation cavity 9451 is provided with a fusible isolator. The isolator can switch between a molten state and an unmolten state (usually solid). When not being detected by the detection card 93, the isolator can be controlled to be in the unmolten state. In this state, the isolator can prevent the sample from entering the detection cavity 9461 through the flow channel (e.g., ...). Figure 52 (as shown). In some embodiments, the spacer may be paraffin, microcrystalline wax, synthetic wax, or natural wax.

[0904] The main body 94 has a recessed detection chamber 9461 on the side near the isolation layer 95 and opposite to the second insertion part 946. The detection chamber 9461 contains reagents. The isolation chamber 9451 communicates with the detection chamber 9461 on the side near the isolation layer 95. The isolator within the isolation chamber 9451 can also be used to seal and isolate the reagent, preventing the reagent from re-entering the isolation chamber 9451 and maintaining the reagent within the detection chamber 9461. During testing, the isolator can be controlled to be in a molten state, at which point the sample can enter the detection chamber 9461 through the sample application chamber 9411 to react with the reagents within the detection chamber 9461, thereby completing the detection.

[0905] The detection chamber 9461 may contain a stacked arrangement of reagents and a fusible isolator. In some embodiments, the isolator may be paraffin, microcrystalline wax, synthetic wax, or natural wax. The isolator is characterized by being solid at room temperature and low temperatures, becoming liquid upon heating to a specific temperature, and having no inhibitory effect on nucleic acid amplification reactions. In some embodiments, the reagent may be a dry reagent, comprising one or more of the following: primers used in the amplification reaction, DNA (deoxyribonucleic acid) binding dyes, enzymes, magnesium sulfate, potassium chloride, and dNTPs (nucleoside triphosphates). The dry reagent is loaded into the detection chamber 9461 in a liquid state and formed into a dry reagent through a drying process. The drying process temperature is lower than the melting temperature of the isolator, and the drying process includes air drying, oven drying, and freeze drying. During the detection heating process, both the reagent and the isolator remain liquid. Because the isolator has a lower specific gravity than the reagent, it will be displaced from the detection chamber 9461 under the action of a centrifugal field, thus not affecting the reaction and detection.

[0906] In some embodiments, the isolator is loaded into the detection chamber 9461 in a molten state and solidified naturally or by cooling. When not being tested, the isolator can be kept in an unmelted state, allowing for the sealed and isolated storage of reagents. When testing is required, the isolator can be kept in a molten state, for example, by heating the detection card 93 to melt the isolator. Under centrifugal force, the isolator can be moved out of the detection chamber 9461 and flow into the isolation chamber 9451, while the sample can enter the detection chamber 9461. The isolator then solidifies again to seal the opening of the detection chamber 9461, thereby creating a mutual isolation seal between multiple detection chambers 9461, allowing each detection chamber 9461 to react or be tested independently.

[0907] The main body 94 has a flow channel 947 on the side near the isolation layer 95 to connect the sample application chamber 9411 and the isolation chamber 9451.

[0908] The main body 94 has an abutment groove 948 on the side away from the isolation layer 95 and opposite to the flow channel 947, so as to cooperate with the abutment part 8336. For example, the abutment part 8336 can be placed in the abutment groove 948 to heat the part of the flow channel 947, prevent water vapor from condensing in the flow channel 947, thereby reducing the impact on subsequent detection processes and improving detection accuracy. In some embodiments, the abutment groove 948 may be omitted.

[0909] The isolation layer 95 can be a membrane structure, or other structures. The isolation layer 95 can be made of materials such as compacting adhesive, UV-cured adhesive, or optical-grade double-sided tape, or it can be a material similar to the main body 94. The isolation layer 95 can be attached to the main body 94, specifically through methods such as ultrasonic welding, laser welding, or adhesive sealing, to seal and isolate the flow channel 947, waste liquid chamber 9441, isolation chamber 9451, and detection chamber 9461.

[0910] The cover 96 is positioned over the opening of the sample application chamber 9411 to seal and isolate it. When a sample needs to be added, the cover 96 can be opened, the sample added to the sample application chamber 9411, and then the cover 96 can be closed. The cover 96 is both water-resistant and air-permeable, allowing water vapor generated during heating to escape and reducing the air pressure inside the test card 93, thus ensuring good air permeability. Furthermore, it prevents the escape of aerosols and biomolecules generated during the amplification reaction, avoiding contamination of personnel and the environment.

[0911] When the test card 93 is centrifuged, the sample liquid flows through the sample application chamber 9411 and the flow channel 947. At this time, the isolator is solid, thus sealing the test chamber 9461 and preventing the sample liquid from flowing into it. After the sample liquid is heated, the isolator melts and flows into the test chamber 9461, making the flow channel 947 and the test chamber 9461 interconnected, allowing the sample liquid to flow into the test chamber 9461. Because the specific gravity of the isolator is less than that of the reagent, under the action of the centrifugal field, the isolator will be displaced onto the reagent without affecting the reaction and detection, while simultaneously sealing the test chamber 9461.

[0912] Some embodiments of this application also provide a method for detection based on the detection card 93 described above. This method can be used in the molecular diagnostic device 100 described above. Please refer to... Figure 53 , Figure 53 for Figure 50 A diagram illustrating the process of using the detection card. The specific steps are as follows:

[0913] Step S5301: The sample addition chamber receives the sample.

[0914] After adding the sample to the sample application chamber 9411, the sample needs to be pre-treated by heating. Heating methods can include metal heating blocks, heating gas flow, electromagnetic waves (infrared radiation, laser, microwave), etc. The heating area of ​​the test card can be the area near the sample application chamber. The heating process requires raising the temperature to a specified temperature, such as 90℃. After reaching the specified temperature, maintain the temperature for 3-10 minutes as required to complete the pretreatment. After pretreatment, lower the temperature of the sample liquid to a specified temperature, such as 60℃.

[0915] Step S5302: The detection card is rotated by centrifugal force so that the sample flows through the flow channel into the detection chamber.

[0916] The rotation of the test card is controlled by centrifugation. For example, the rotation direction can be controlled to be clockwise, the rotation speed greater than 1000 rpm, and the rotation time approximately 10-15 seconds. Through rotation, the sample liquid can flow from the sample application chamber to the detection chamber through the flow channel, facilitating the subsequent filling of the detection chamber with sample. Excess sample liquid will enter the waste liquid chamber.

[0917] Step S5303: Heat and melt the separator so that the sample flows into the detection chamber and mixes with the reagent in the detection chamber.

[0918] Here, the area near the detection chamber needs to be heated to a temperature higher than the melting point of the insulator, thereby melting the insulator and mixing the sample with the reagent in the detection chamber.

[0919] Step S5304: Centrifuge and rotate to replace the sample in the detection chamber with the isolator, and seal the entrance end of the detection chamber.

[0920] The detection card is rotated again. The motor can rotate clockwise at a speed greater than 1000 rpm for 10-15 seconds. During this rotation, the sample enters the detection chamber, and the isolator and the aqueous solution in the chamber are exchanged. The isolator moves to the inlet of the detection chamber, thus sealing each chamber. Then, the motor control parameters are changed to make the detection card rotate alternately clockwise and counterclockwise. For example, the detection card can be controlled to first rotate clockwise at 3000 rpm for 1 second, then counterclockwise at 3000 rpm for 1 second, alternating 10-15 times. This alternating clockwise and counterclockwise rotation ensures complete dissolution and mixing of the sample and reagent in the detection chamber.

[0921] Meanwhile, after the insulator is heated and melted, it flows to the inlet of the detection chamber under the action of centrifugal force to seal the inlet of the detection chamber.

[0922] Step S5305: Detect the mixed mixture.

[0923] This step involves both amplification and detection. If real-time detection is used, the detection and amplification reactions occur simultaneously; if endpoint detection is used, detection is performed after amplification is complete. The amplification reaction can be achieved by heating the area near the detection chamber, controlling the temperature between 60℃ and 75℃. After reaching the specified temperature, maintain the temperature for 30-60 minutes as required to complete the amplification reaction.

[0924] The following describes the process of testing samples using molecular diagnostic equipment 100 and test card 93. The specific process is as follows:

[0925] The control circuit board 40 allows users to set basic information such as the number and type of samples to be detected by the detection card 93, heating temperature, rotation speed, and operating parameters via an input device. After the basic information is set, the detection card 93 can be activated via the input device.

[0926] Test card 93 loaded with samples.

[0927] Under the control of the control circuit board 40, the first drive unit 1212 controls the rotation of the first lead screw 1221 and the second lead screw 1222 respectively through the synchronization component 1213, so that the pressure plate 50 drives the transport component 60 to slide on the first guide rail 1126 towards the top plate 111. When the limit plate 5813 triggers the second limit switch 16, such as the second sub-limit switch 163, the pressure plate 50 reaches the predetermined position. The first drive unit 1212 stops operating after the control circuit board 40 receives the signal that the second sub-limit switch 163 has been triggered.

[0928] Under the control of the control circuit board 40, the second drive member 6141 causes the transport member 62 to slide along the second guide rail 613 away from the first connecting plate 6111 via the lead screw 6142. When the transport member 62, for example, triggers the first limit switch 15, the transport member 62 reaches the predetermined position. The second drive member 6141 stops operating after the control circuit board 40 receives the signal that the first limit switch 15 has been triggered.

[0929] The test card 93 loaded with the sample is placed in the recess 653 of the transport component 62, such as the card holder 65. The test card 93, for example, the mounting part 941 is placed in the receiving hole 655. The test card 93, for example, the fourth locking part 942 is locked with the second locking part 654 of the card holder 65, thus completing the placement of one test card 93.

[0930] The control circuit board 40 scans the information markings on the card tray 65 using the barcode scanner 14 and determines whether it is the user-prescribed detection card 93. If not, a warning will be issued. If yes, proceed to the next step.

[0931] Under the control of the control circuit board 40, the third drive unit 64 starts to rotate, driving the card holder 65 to rotate, so that the recess 653 where the next detection card 93 can be placed reaches the predetermined position, and then the placement of the next detection card 93 is operated.

[0932] After placing the detection card 93 in the recess 653 on the card holder 65, the detection cards 93 will be evenly distributed around the circumference of the card holder 65. If the number of detection cards 93 is insufficient to be evenly distributed around the circumference of the card holder 65, a balancing card can be placed in the recess 653 of the card holder 65 so that the balancing card and the detection cards 93 are evenly distributed around the circumference of the card holder 65 together. At this point, the placement of the detectio...
