[0033] Example 1, reference Figure 1 to Figure 11 , which is the first embodiment of the present invention, provides an automated biological sample detector 100, which can provide a large number of glass slides 104 for detection activities within a limited device space, so as to carry a larger number of biological samples, thereby realizing the detection of a larger number of biological samples in a single detection activity of the device.

The two belts 1 202 are synchronously arranged in the same direction when running on adjacent sides; Figure 7 and Figure 8A swing arm 207 is hinged at one end of the bottom plate 201, and an adapter ring 208 is fixedly connected to the end of the swing arm 207. A suction cup 209 is inserted at the top of the adapter ring 208, and a spring 210 is provided between the suction cup 209 and the end surface of the adapter ring 208.

[0035] Specifically, refer to Figure 7 and Figure 8 A bearing 203a is embedded in the top of the short shaft 203, and a U-shaped bracket is arranged at the top of the short shaft 203. The inner ring of the bearing 203a is fixedly connected to the bracket, and the U-shaped opening of the bracket points to the swing arm 207. The end of the adapter ring 208 away from the suction cup 209 is sealed and fixedly connected to the air joint 216. The base plate 201 is located next to the hinge seat 206 and is fixedly connected to a miniature cylindrical cylinder 215, and the end of the piston rod of the miniature cylindrical cylinder 215 is coaxially fixedly connected to the screw 214.

[0036] For further reference, Figure 7 and Figure 8 The swing arm 207 is provided with a slot 207a, and a shift block 211 is slidably connected in the slot 207a. A latch 212 is inserted into the side wall of the adapter ring 208, and one end of the latch 212 is fixedly connected to the shift block 211. One end of the latch 212 matches the plug-in suction cup 209. The latch 212 is located between the shift block 211 and the outer wall of the adapter ring 208 and a spring 213 is provided.

[0037] The structural principle and advantages of the device are further explained in combination with the existing technology: the existing automated biological sample detection equipment uses a servo system to drive the sampling mechanism to sample the biological sample and drip the sample on the carrier (glass slide 104). After the sampling is completed, the platform moves so that the carrier and the biological sample are moved to the detection area for detection. The platform area for placing the carrier is very limited, so the number of biological samples that the device can detect is also limited. When the number of biological samples that need to be detected exceeds the detection capacity of the device, it needs to be performed in batches for multiple times.

[0038] The present invention mainly provides a feeding mechanism 200 for providing glass slides 104 to a detector 100. The feeding mechanism 200 prepares a large number of glass slides 104 for use by vertically arranging and inserting. The feeding mechanism 200 releases the glass slides 104 one by one to a conveyor belt 300, and then the conveyor belt 300 sequentially transports the glass slides 104 to biological sample droplets and detection stations to complete biological sample sampling and detection. The feeding mechanism 200 of the glass slide 104 is different from the existing biological sample automatic detection equipment in terms of working form;

[0039] To achieve the above functions, firstly, the feeding mechanism 200 uses a high-strength bottom plate 201 as the structural basis, and two parallel belts 1 202 are installed on the bottom plate 201. A large number of vertical ribs 202a are designed on the surface of the belt 1 202. The gaps between the ribs 202a are used to insert the glass slide 104. The structure involves the following technical details:

[0040] The feeding mechanism 200 takes and delivers the glass slides 104 through the suction cup 209, and the glass slides 104 need not only to be parallel to each other, but also to be perpendicular to the belt 1 202. Figure 6 As shown, the suction cup 209 can correctly fit and absorb the surface of the glass slide 104. To achieve this function, the two belts 1 202 need to be debugged symmetrically and keep the symmetry unchanged during repeated operation. Therefore, the belt 1 202 and the belt 2 205 need to run synchronously, as shown in FIG. Figure 5 and Figure 6 As shown, the device adopts the method of winding the belt 205 to keep the two belts 1 202 in synchronization, wherein the roller 204 is provided with two belt grooves, and the bottom end of the short shaft 203 is provided with a belt groove, and the belt 205 is an annular PU round belt with a steel wire core. Figure 6 Taking the perspective as an example, the winding method is that the two sections of the belt 205 extending from the two sides of the short shaft 203 are respectively overlapped in the two belt grooves of the roller 204, and the belt 205 extending from the roller 204 is crossed and reversed in an X shape and then wound around another short shaft 203, so that when any belt 1 202 is dragged, the belt 1 202 can drive another belt 1 202 through the short shaft 203 and the belt 2 205 to realize synchronous and reverse operation (one belt 1 202 runs clockwise, and the other belt 1 202 runs counterclockwise), so that the two belts 1 202 and the contact side of the glass slide 104 run synchronously and in the same direction;

[0041] By setting one end of the belt 205 in a cross-reverse direction, the two short shafts 203 can be synchronized in reverse rotation, and the height difference between the two belt grooves on the roller 204 can be used to avoid contact friction and wear at the intersection of the belt 205. By selecting a PU round belt with a steel wire core, the elastic deformation and elongation of the belt 205 can be avoided to prevent the two short shafts 203 from running out of sync. In addition to being more economical than the traditional gear reversing structure, this structure also avoids the problem of virtual position caused by tooth clearance (the transmission clearance will cause the position difference between the two belts 1 202, which will cause the glass slide 104 to swing and become unstable).

[0042] Since the suction cup 209 moves in an arc path with the swing arm 207, the swing arm 207 cannot swing downward directly after the suction cup 209 absorbs the glass slide 104, which will cause the bottom of the glass slide 104 to be squeezed and broken by the bottom plate 201. Therefore, the device swings the swing arm 207 upward to make the suction port of the suction cup 209 contact the glass slide 104, and connects the suction cup 209 to the negative pressure source through the air joint 216, so that the negative pressure makes the suction cup 209 absorb the glass slide 104. Figure 8 As shown, after the glass slide 104 is adsorbed, the suction cup 209 tends to shrink into the adapter ring 208 under the negative pressure, thereby compressing the spring 1 210 to pull the glass slide 104 horizontally out from between the belts 1 202. After the glass slide 104 is separated from the belt 1 202, it can be safely deflected with the swing arm 207. During the process of the glass slide 104 being pulled out of the belt 1 202 horizontally, the belt 1 202 will be moved a short distance through the rib 202a, so that the adjacent glass slide 104 reaches the waiting position;

[0043] After the suction cup 209 successfully obtains the glass slide 104, the swing arm 207 deflects downward so that the glass slide 104 is converted from a vertical state to a horizontal state. Fig. 9 As shown, the suction cup 209 is between the belts 301, and the glass slide 104 is placed flat on the belts 301. The structure involves the following technical details:

[0044] The suction cup 209 should maintain internal negative pressure during the movement of the swing arm 207. When the swing arm 207 reaches the lower dead point, assuming that the suction port of the suction cup 209 reaches the designated position, and the suction port of the suction cup 209 is level with the belt 301, the negative pressure ends and the suction cup 209 releases the glass slide 104. The spring 1 210 will lift the suction cup 209 and the glass slide 104, and the glass slide 104 will be difficult to contact the belt 301, and thus cannot be transported to the next station by the belt 301. Therefore, a shift block 211 is designed between the swing arm 207 and the adapter ring 208. The shift block 211 is limited by the width of the slot 207a and can only slide in the slot 207a. It is also limited by the latch 212 to determine the direction of its sliding. Figure 6 and Figure 8As shown, when the swing arm 207 deflects downward by ninety degrees, the end face of the swing arm 207 abuts against the hinge seat 206 to limit the position. During the process, the shift block 211 abuts against the positioning buckle 206a at the bottom edge of the hinge seat 206, causing it to shrink into the slot 207a, thereby compressing the spring 213 so that the pin 212 is inserted into the side wall of the suction cup 209. At this time, the negative pressure ends so that the suction cup 209 releases the glass slide 104. The suction cup 209 will not bounce upward under the restriction of the pin 212, and the belt 3 301 can smoothly transport the glass slide 104 to the next workstation.

[0045] The up and down swing of the swing arm 207 is powered by a micro cylindrical cylinder 215, which drives the screw 214 to extend and retract, and drives the swing arm 207 to deflect through the high-lead spiral groove on the screw 214. Since the swing arm 207 only needs to deflect 90 degrees, the spiral groove of the screw 214 only needs to have about half a turn.

[0046] In summary, compared with the traditional glass slide 104 operating platform, the device replaces the conventional flat storage form with a three-dimensional storage form, which can continuously provide a large number of glass slides 104 for biological sample fluorescence detection equipment during detection activities, so that the glass slide 104 capacity of the detection equipment is no longer a factor restricting the efficiency of biological sample fluorescence automated detection.

[0047] Example 2, reference Figure 1 , Figure 2 , Figure 9~Figure 11 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a conveyor belt 300 of the biological sample automatic detection instrument 100, which cooperates with the feeding mechanism to move the glass slide 104 to the next process, and the glass slide 104 completes the acquisition and detection of the biological sample. Figure 1 The detector 100 is also provided with a servo-driven dropper 101 and a bioluminescent sensor 102, and the detector 100 is provided with a conveyor belt 300 at the bottom of the dropper 101 and the bioluminescent sensor 102. Figure 2 One end of the conveyor belt 300 is adjacent to the swing arm 207, and the conveying directions of the conveyor belt 300 and the belt 1 202 are parallel to each other. Fig. 9 and Fig.10 , two belts 301 are arranged inside the conveyor belt 300 and are distributed on both sides of the conveyor belt 300. The conveyor belt 300 is located in the rotation radius range of the swing arm 207, the suction cup 209 and the air joint 216 and is hollowed out. When the swing arm 207 is at the deflection lower dead point position, the suction port height of the suction cup 209 is coplanar with the upper plane of the belt 301, the suction cup 209 is located in the middle position between the two belts 301, and the suction cup 209 corresponds to the position of the dropper 101 above. Fig.10 and Fig.11The bottom surface of the conveyor belt 300 is equipped with a fluorescence excitation light source 103 at a position corresponding to the bioluminescence sensor 102 .

[0048] The feeding mechanism 200 works with the conveyor belt 300. The conveyor belt 300 uses two narrow belts 301 distributed on both sides thereof, so that the middle part is hollowed out to leave room for the swing arm 207 to move and avoid blocking the fluorescent excitation light source 103. Figure 1 The working process of the conveyor belt 300 is as follows: the suction cup 209 releases the glass slide 104 on the conveyor belt 300, the dropper 101 releases the biological sample on the glass slide 104, and the conveyor belt 300 moves the glass slide 104 and the biological sample to between the fluorescent excitation light source 103 and the biological fluorescence sensor 102 for detection. The above process is repeated until the biological sample to be detected is tested or all the glass slides 104 in the feeding mechanism 200 are used.

[0049] The rest of the structure is the same as that of Example 2.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
