[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Gene sequencing technology is also called DNA sequencing technology, which is the technology of obtaining the base arrangement order of the target DNA fragment. Obtaining the sequence of the target DNA fragment is the basis for further molecular biology research and gene modification. Gene sequencing requires the biochip to be pressed and fixed on the detection mainboard, and the biochip is tested under a certain pressure. In the prior art, after the chip is placed in the detection position, it is necessary to manually adjust the pressing device to press the chip to the detection position. Too much pressing force will damage the chip, and too little pressing force will affect the chip detection. The manual adjustment error is large, which makes the chip detection device poor in pressing the chip.

[0040] like Figures 1 to 11 As shown, in order to solve the above technical problems, the present application provides a loading mechanism 100 , which is used to load the chip 200 onto the mainboard. The loading mechanism 100 includes a driving module 110 , a carrying module 120 and a pressing module 130 .

[0041] like Figure 1 , Fig. 9 , Fig.10 as well as Fig.11 As shown, the driving module 110 includes a first driving part 111 and a second driving part 112. The first driving part 111 is used to drive the bearing part 121 to move from the first position to the second position, and the second driving part 112 is used to drive the pressing part 131 to press and fix the chip 200 to the motherboard.

[0042] like Figure 1 , Figure 5 as well as Figure 6As shown, the carrier module 120 includes a carrier part 121 for carrying a chip 200, and the first driving part 111 can drive the carrier part 121 to move from a first position to a second position. When the carrier part 121 is located at the first position, the carrier part 121 is suitable for placing the chip 200, and when the carrier part 121 is located at the second position, the chip 200 placed on the carrier part 121 is docked with the mainboard. The path of the carrier part 121 moving from the first position to the second position can be arbitrary, and the carrier part 121 can be translated from the first position to the second position in any suitable direction, and can also be deflected at a certain angle during the movement, as long as the carrier part 121 can dock the chip 200 with the mainboard, there is no limitation here. When the bearing part 121 is located at the first position, in order to place the chip 200 on the bearing part 121, according to the different shapes of the chip 200, the bearing part 121 may be provided with a slot 1211 of different shapes for placing the chip 200 or a clamping part for clamping the chip 200. Specifically, the slot 1211 may be an annular or rectangular slot, etc. In order to facilitate the pressing part 131 to press the chip 200 on the mainboard, specifically, the bearing part 121 may be provided with a through hole, and the chip 200 is connected to the wall of the through hole. In the second position, one side of the chip 200 abuts against the mainboard and the other side abuts against the pressing part 131. It should be noted that the docking of the chip 200 with the mainboard refers to the alignment of the tested point on the chip 200 with the detection point on the mainboard, so that the mainboard can detect the position of the chip 200.

[0043] like Figure 1 , Figure 8 as well as Fig.11 As shown, the pressing module 130 includes a pressing portion 131, which is disposed on the side of the carrier 121 away from the mainboard. When the carrier 121 is located at the second position, the second driving portion 112 can drive the pressing portion 131 to move toward the carrier 121 to press the chip 200 against the mainboard. To facilitate pressing the chip 200 against the mainboard, the pressing portion 131 can be any shape that is convenient for cooperating with the chip 200 and the carrier 121. The second driving portion 112 drives the pressing portion 131 so that the pressing portion 131 presses the chip 200 against the mainboard at a set pressure.

[0044] In the technical solution of the present application, the driving module 110 is provided with a first driving part 111 and a second driving part 112. The first driving part 111 can drive the bearing part 121 so that the bearing module 120 can dock the chip 200 with the mainboard, and the second driving part 112 can drive the pressing part 131 so that the pressing part 131 can press the chip 200 to the mainboard, thereby realizing the automatic loading of the chip 200. The cooperation of the driving module 110, the bearing module 120 and the pressing module 130 makes the pressing and docking of the chip 200 with the mainboard more intelligent and controllable. Since the driving module 110 can more accurately and stably control the pressure applied by the pressing module 130 to the chip 200, the technical solution of the present application can improve the stability of the loading of the chip 200, and the risk of the chip 200 not being loaded properly and the chip 200 being damaged is greatly reduced.

[0045] In some embodiments, the carrying portion 121 and the pressing portion 131 may be configured as different structures according to different chip 200 placement requirements. Figure 3 , Figure 6 as well as Fig.11 As shown, in this embodiment, the carrier 121 is provided with a slot 1211 for placing the chip 200, the pressing portion 131 is provided with a protrusion 1311 corresponding to the slot 1211, and the second driving portion 112 can drive the pressing portion 131 to move from the third position to the fourth position. When the pressing portion 131 is located at the third position, the pressing portion 131 is separated from the carrier 121, so that the chip 200 can be placed on the carrier module 120. When the pressing portion 131 is located at the fourth position, the pressing module 130 presses the chip 200 placed on the carrier 121 located at the second position onto the mainboard. Specifically, as shown in FIG. Figure 6 As shown, the bearing part 121 limits a slot 1211 with an opening, and the chip 200 is pushed into the slot 1211 along the second direction, and the chip 200 abuts against the wall of the slot 1211, so that the chip 200 is clamped to the bearing part 121. In order to facilitate the pressing part 131 to press the chip 200, the pressing part 131 is provided with a protrusion 1311. When the pressing part 131 is located at the fourth position, if the side of the chip 200 close to the pressing part 131 is located in the slot 1211, the protrusion 1311 can extend into the slot 1211 to press the chip 200. In some embodiments, if the bearing part 121 is configured as a boss and the chip 200 is disposed on the boss, the pressing part 131 can also be configured as a groove, which will not be repeated here.

[0046] When the carrying part 121 moves from the first position to the second position, the higher the running stability of the carrying part 121, the higher the docking accuracy of the chip 200 and the motherboard. Figure 1 , Figure 5 as well as Fig.11As shown, in some embodiments, the loading mechanism 100 includes a base 140, and the carrier module 120 includes a guide portion 122, the guide portion 122 is fixedly connected to the base 140, and the carrier portion 121 is slidably connected to the guide portion 122 along the first direction X, and the guide portion 122 is used to guide the carrier portion 121 to switch from the first position to the second position along the first direction X, wherein the first direction X is perpendicular to the contact plane between the mainboard and the chip 200. According to different usage requirements, the structure of the guide portion 122 may be different, and specifically, the guide portion 122 may be any suitable component such as a plate, a rod or a slide rail. The guide portion 122 may be connected to the carrier portion 121 and the pressing portion 131 in any suitable manner. In some embodiments, the guide portion 122 may be fixedly connected to the base 140, and the carrier portion 121 and the pressing portion 131 are slidably connected to the guide portion 122. In some embodiments, the bearing portion 121 and the pressing portion 131 can be fixedly connected to the guide portion 122 respectively, and the guide portion 122 is slidably connected to the base 140, so that the guide portion 122 can respectively drive the pressing portion 131 and the bearing portion 121 to move. Figure 5 As shown, in this embodiment, the bearing portion 121 limits a first through hole 1212, the guide portion 122 is configured as a columnar shaft, the guide portion 122 is disposed through the first through hole 1212, and the axis of the guide portion 122 is parallel to the first direction X. In other words, when the bearing portion 121 moves from the first position to the second position, since the axis of the guide portion 122 is perpendicular to the contact surface between the mainboard and the chip 200, the chip 200 can be accurately positioned on the mainboard along the first direction X under the clamping of the bearing portion 121. In some embodiments, the first axis may not be perpendicular to the contact surface between the mainboard and the chip 200, as long as the bearing portion 121 can position the chip 200 on the mainboard.

[0047] In some embodiments, in order to further improve the stability of the loading assembly pressing the chip 200, the guide portion 122 can also be connected to the carrying portion 121 and the pressing portion 131 at the same time. Figure 8 as well as Fig. 9 As shown, in this embodiment, the clamping module 130 limits the second through hole 132, one end of the guide portion 122 is arranged in the first through hole 1212, and the other end is arranged in the second through hole 132. The bearing portion 121 moves from the first position to the second position along the axis parallel to the guide portion 122, and the clamping portion 131 moves from the third position to the fourth position along the axis parallel to the guide portion 122. The setting of the guide portion 122 greatly improves the clamping accuracy of the clamping portion 131 on the chip 200, thereby improving the clamping stability of the loading assembly.

[0048] In order to improve the degree of automation of loading the chip 200, the carrier 121 may be provided with a trigger component. When the chip 200 is placed on the carrier 121, the trigger component on the carrier 121 can be triggered, so that the carrier 121 can move from the first position to the second position. Specifically, the trigger component can be configured as an electric switch such as a photoelectric switch, a magnetic switch, or any other suitable mechanical switch. Figure 2 , Figure 6 as well as Figure 7 As shown, in this embodiment, the loading mechanism 100 includes a base 140, which limits a locking groove 141, and the carrier module 120 includes a locking portion 123 and a first elastic member 124. The first elastic member 124 is arranged on the side of the locking portion 123 away from the card slot 1211 for placing the chip. When the carrier 121 is located at the first position, the locking portion 123 is buckled in the locking groove 141. When the carrier 121 is located at the second position, the chip 200 can push the locking portion 123 to move away from the card slot 1211, so that the locking portion 123 is separated from the locking groove 141. That is, when the carrier 121 is located at the first position, one end of the locking portion 123 is penetrated in the card slot 1211, and the other end is buckled in the locking groove 141, so that the carrier 121 can remain stationary relative to the base 140. The chip 200 enters the card slot 1211 and can push the locking portion 123 to move to a side away from the chip 200, thereby separating the locking portion 123 from the locking slot 141 of the base 140. Specifically, the bearing portion 121 can limit a mounting hole connected to the card slot 1211, and the locking portion 123 is penetrated into the card slot 1211 through the mounting hole, so that when the chip 200 is placed in the card slot 1211, the locking portion 123 can be pushed to move to a side away from the card slot 1211. The separation of the locking portion 123 from the locking slot 141 releases the limit of the bearing portion 121 by the base 140, and the bearing portion 121 can move from the first position to the second position. When the chip 200 is taken out from the card slot 1211, the pressing force of the chip 200 on the locking part 123 disappears, and the force of the locking part 123 on the first elastic member 124 is released. Under the action of the first elastic member 124, the locking part 123 can return to the original position of the card slot 1211, so that the locking part 123 can be inserted into the locking slot 141 again. It should be noted that the first elastic member 124 is arranged on the side of the locking part 123 away from the card slot 1211, one end of the first elastic member 124 is connected to the locking part 123, and the other end can be connected to the wall surface of the base 140 or the wall surface of the bearing part 121. Specifically, the end of the first elastic member 124 away from the locking part 123 can be arranged on the side of the locking part 123 close to the card slot 1211, and can also be arranged on the side of the locking part 123 away from the card slot 1211. When the end of the first elastic member 124 away from the locking portion 123 is disposed on a side of the locking portion 123 close to the card slot 1211, the chip 200 pushes the locking portion 123 and the first elastic member 124 is stretched. Figure 6as well as Figure 7 As shown, in this embodiment, one end of the first elastic member 124 away from the locking portion 123 can be arranged on a side of the locking portion 123 away from the card slot 1211, and when the chip 200 pushes the locking portion 123, the first elastic member 124 is compressed. The arrangement of the locking portion 123 and the first elastic member 124 greatly improves the convenience of fixing the carrying portion 121 at the first position, and the degree of automation of releasing and limiting the carrying portion 121 when the chip 200 is taken or placed. To facilitate the separation and engagement of the locking portion 123 and the locking groove 141, the locking portion 123 can be configured as a hook, and the end of the hook close to the carrying portion 121 has a wall surface parallel to the contact surface between the carrying portion 121 and the chip 200, so as to facilitate the separation of the locking portion 123 from the wall surface of the locking groove 141, and the side of the hook away from the carrying portion 121 is provided with an inclined surface, which intersects with the contact surface between the carrying portion 121 and the chip 200. The inclined surface can guide the locking portion 123 to be engaged with the locking groove 141, so as to improve the convenience of fixing the carrying portion 121 in the first position.

[0049] After the chip 200 is placed in the card slot 1211, the first driving part 111 can drive the carrying part 121 to move from the first position to the second position by any suitable means such as a linear motor, a cylinder or an elastic member. Figure 5 , Figure 8 , Fig. 9 as well as Fig.11As shown, in this embodiment, the first driving part 111 includes a second elastic member 1111 and a limiting member 1112, the second elastic member 1111 is arranged around the limiting member 1112, the pressing part 131 limits the third through hole 1312, one end of the limiting member 1112 is connected to the bearing part 121, and the other end is passed through the third through hole 1312 and can move relative to the pressing part 131 along a direction parallel to the axis of the third through hole 1312, wherein, when the bearing part 121 is located at the first position, the second elastic member 1111 can generate an elastic force parallel to the first direction X and directed from the pressing part 131 to the bearing part 121. The limiting member 1112 can be fixedly connected to the bearing part 121 by welding, gluing, etc., or connected to the bearing part 121 by threaded connection, etc. Specifically, the bearing portion 121 may limit a fourth through hole 1213, the fourth through hole 1213 is a threaded hole, one end of the stopper 1112 is passed through the fourth through hole 1213 and is fixedly connected to the bearing portion 121 by threads. The second elastic member 1111 may be provided at a side of the bearing portion 121 close to the pressing portion 131, one end of the second elastic member 1111 is connected to the bearing portion 121, and the other end is connected to the pressing portion 131. When the bearing portion 121 is located at the first position, one end of the stopper 1112 close to the pressing portion 131 passes through the third through hole 1312 to the side of the pressing portion 131 away from the bearing portion 121, the second elastic member 1111 is compressed, and after the chip 200 is inserted into the card slot 1211, the locking portion 123 is separated from the locking slot 141, and the elastic force of the second elastic member 1111 can make the bearing portion 121 move to the second position to the side away from the pressing portion 131. The second elastic member 1111 can also be arranged on the side of the bearing part 121 away from the pressing part 131. Specifically, one end of the second elastic member 1111 is connected to the bearing part 121 and the other end is connected to the base 140. When the bearing part 121 is in the first position, the second elastic member 1111 is stretched, so that when the locking part 123 is separated from the locking groove 141, the bearing part 121 can move to the second position under the action of the elastic force. It will not be repeated here. When the second elastic member 1111 drives the bearing part 121 to move from the first position to the second position, the end of the limiter 1112 close to the pressing part 131 falls back to the third through hole 1312 and is clamped to the pressing part 131. The length of the limiter 1112 along the first direction X can be selected according to the distance between the first position and the second position and the force of the second elastic member 1111. The setting of the limiter 1112 makes the deformation of the second elastic member 1111 more stable, and the accuracy of the bearing part 121 moving from the first position to the second position is higher.

[0050] The second driving member 1121 can drive the pressing portion 131 in different ways so that the pressing portion 131 can press the chip 200. Figure 2 , Fig.10 as well as Fig.11As shown, in this embodiment, the second driving part 112 includes a driving member 1121, a first transmission member 1122 and a second transmission member 1123, one end of the first transmission member 1122 is connected to the driving member 1121, and the other end is connected to the second transmission member 1123, the loading mechanism 100 includes a base 140, the base 140 limits a guide groove 142 extending along a first direction X, one end of the second transmission member 1123 away from the first transmission member 1122 is inserted into the guide groove 142 and connected to the pressing part 131, and the first direction X is perpendicular to the contact plane between the mainboard and the chip 200. The driving member 1121 can be configured as a motor, and the driving member 1121 controls the displacement of the pressing part 131 and the pressure of the pressing part 131 on the chip 200 by controlling the rotation angle of the motor. Specifically, the motor drives the first transmission member 1122 to swing, and the swing of the first transmission member 1122 drives the second transmission member 1123 to move. Due to the limitation of the guide groove 142, the end of the second transmission member 1123 away from the first transmission member 1122 can slide in the guide groove 142 driven by the first transmission member 1122, thereby driving the clamping portion 131 to move closer to or away from the bearing portion 121. To further ensure the normal operation of the drive module 110, the drive module 110 may also be provided with a temperature sensor and a fan. The temperature sensor is used to detect the temperature of the motor, etc. When the temperature exceeds the set value, the fan starts to cool the motor. It is understandable that in some embodiments, in order to improve the driving ability of the second drive portion 112 on the clamping portion 131, the second drive may also be provided with a plurality of transmission members connected to the output shaft of the motor and in contact with the clamping portion 131 at different positions, which will not be repeated here. It is understandable that, if Figure 2 As shown, the base 140 may include a body 143 , a front plate 144 and a rear plate 145 . The body 143 defines the guide groove 142 , the front plate 144 defines the entrance of the chip 200 , and the rear plate 145 defines the locking groove 141 .

[0051] like Figure 4 , Figure 5 , Figure 7 as well as Fig.11As shown, in this embodiment, during the loading process of the chip 200, first, the base 140 may be provided with an opening, the opening being connected to the slot 1211 of the bearing portion 121, the chip 200 enters the slot 1211 from the opening, and pushes the locking portion 123 to release the bearing portion 121, at which time the first elastic member 124 is compressed, and the bearing portion 121 drives the chip 200 from the first position to the second position under the drive of the second elastic member 1111. Then, the second driving portion 112 drives the pressing portion 131 to move from the third position to the fourth position, and the second driving portion 112 controls the rotation angle of the motor to control the pressing portion 131 to press the chip 200, at which time the second elastic member 1111 is further compressed. After the detection is completed, the second driving portion 112 drives the pressing portion 131 to return from the fourth position to the third position. After the pressing part 131 is separated from the bearing part 121, the chip 200 can be withdrawn, the chip 200 is separated from the wall of the card slot 1211, the thrust of the chip 200 disappears, and the first elastic member 124 can push the locking part 123 to move to the side close to the card slot 1211, so that the locking part 123 returns to its original position. Since the guide part 122 and the first driving part 111 are connected to the bearing part 121 and the pressing part 131, when the pressing part 131 returns to the third position, it will drive the bearing part 121 to return to the first position. Specifically, the second driving part 112 drives the pressing part 131 to move to the side away from the chip 200, and the bearing part 121 follows the pressing part 131 and moves to the side of the pressing part 131 away from the chip 200 at the same time. When the bearing part 121 moves to the first position, the locking part 123 is buckled into the locking groove 141 again, so that the bearing part 121 is fixed in the first position. It should be noted that, since the first driving part 111 is provided between the bearing part 121 and the pressing part 131, when the second driving part 112 drives the pressing part 131 to move to the side away from the chip 200, the distance between the pressing part 131 and the bearing part 121 increases, and the driving force of the second elastic member on the bearing part 121 decreases with the movement of the pressing part 131. In order to make the second elastic member 1111 have sufficient driving force so that the bearing part 121 can move from the first position to the second position after the locking part 123 is separated from the locking groove 141, after the bearing part 121 is fixed in the first position, the second driving part 112 can drive the pressing part 131 to move in the direction close to the bearing part 121, so that the second elastic member 1111 is compressed again, and finally when the pressing part 131 is in the third position, the second elastic member 1111 obtains the elastic potential energy that drives the bearing part 121 to move from the first position to the second position.That is to say, the second driving part 112 drives the clamping part 131 to move from the fourth position to the third position, and drives the bearing part 121 to return from the second position to the first position. Since the first driving part 111 in an uncompressed state is provided between the clamping part 131 and the bearing part 121, when the bearing part 121 returns to the first position, the clamping part 131 is in the third position away from the side of the bearing part 121, and the second driving part 112 drives the clamping part 131 in the reverse direction to make the clamping part 131 move toward the side close to the bearing part 121, so that when the clamping part 131 returns to the third position, the second elastic member 1111 is compressed again, and the loading assembly returns to the initial state and can load the chip 200 next time. The loading device of the present application has a compact structure and a high degree of intelligence. The driving components involved in the loading process of the biochip 200 have a compact structure, simple control placement, and a stable system. It does not need to rely on manual loading, has a low degree of automation, and is stable in loading.

[0052] like Figure 1 , Figure 6 , Fig. 9 as well as Fig.11 As shown, according to different requirements of the detection of the biochip 200, the loading mechanism 100 may also include a liquid circuit module 150, and the liquid circuit module 150 is connected to the pressing module 130, and the liquid circuit module 150 is used to conduct liquid to the chip 200. Specifically, the liquid circuit module 150 may include a liquid inlet pipe, a liquid outlet pipe, a guide pipe, a valve, a bubble detector, etc., and the liquid circuit module 150 may be connected to the pressing part 131. The liquid inlet pipe is connected to the guide pipe, and the end of the guide pipe away from the liquid inlet pipe is used to connect with the liquid inlet of the chip 200, the liquid outlet on the chip 200 is connected to the liquid outlet pipe, and the bubble detector is connected to the liquid outlet pipe. The liquid enters the guide pipe from the liquid inlet pipe, and the guide pipe is connected to the interface on the chip 200, and then the liquid is introduced into the chip 200, and the liquid flows from the core to the liquid outlet pipe. The bubble detector can detect whether there are bubbles in the liquid outlet pipe. In some embodiments, in order to facilitate the control of the flow path of the liquid in the chip 200, the liquid circuit module 150 may include a liquid circuit control valve 151, and a liquid circuit valve 210 is provided on the side of the chip 200 close to the clamping module 130. Specifically, the clamping portion 131 limits a through hole, and the liquid circuit control valve 151 is penetrated through the through hole and can be docked with the liquid circuit valve 210 on the chip 200. When the bearing portion 121 is located at the second position, the liquid circuit control valve 151 is connected to the liquid circuit valve 210, and the liquid circuit control valve 151 is used to control the opening and closing of the liquid circuit valve 210. According to different usage requirements, the liquid circuit module 150 can be provided with multiple liquid circuit control valves 151 to realize the control of the opening and closing of the liquid circuits of different parts of the chip 200 for detection.
