[0041] The PCR plate is a laboratory instrument used for PCR amplification in molecular biology experiments. In the experimental process of the molecular pipeline, multiple PCR plates need to be placed on the device manually, and the multiple PCR plates are used for the transfer and storage of reagents in the experimental process of the device.
[0042] The existing feeding mechanism lacks a counting function, which causes inconvenience in knowing how many PCR plates are stored in the feeding mechanism during use.
[0043] The utility model provides a kind of feeding mechanism, for the storage of PCR plate (material).
[0044] Please refer to Figure 6 In an embodiment of the present application, the feeding mechanism 100 comprises: a storage part 110, a receiving part 120, a driving unit 130, and a counting module 140; wherein the storage part 110 is provided with a storage cavity 111, and the storage cavity 111 is provided with an inlet and outlet 112 for feeding and discharging the material 500. It should be noted that the material 500 is placed in the storage cavity 111, and specifically, the material 500 is arranged in layers (see Figure 2 、 Figure 3 ); further, the receiving part 120 and the driving unit 130 are arranged in the storage cavity 111, the receiving part 120 is used for placing the material 500 in layers, and can move in the storage cavity 111, and the driving unit 130 can drive the receiving part 120 to move towards the inlet and outlet 112. It can be understood that the material 500 is arranged in layers in the storage cavity 111, and the bottom layer of the material 500 is placed on the receiving part 120. When the driving unit 130 drives the receiving part 120 to move towards the inlet and outlet 112, the receiving part 120 can push the material 500 out of the inlet and outlet 112, so as to output the material 500 from the storage part 110. Further, in some embodiments, the driving unit 130 can be an electric telescopic rod, which can drive the receiving part 120 to move towards the inlet and outlet 112, or to move away from the inlet and outlet 112. Further, in this embodiment, during the assembly process of the material 500, the user can assemble the material 500 into the storage cavity 111 from the inlet and outlet 112, and at this time, the electric telescopic rod can drive the receiving part 120 to be located at the lowest position, that is, the distance between the receiving part 120 and the inlet and outlet 112 is the farthest.
[0045] Further, the counting module 140 comprises a triggering part 141 and a sensing part 142, when one of the materials 500 enters or exits the storage cavity 111, the triggering part 141 can trigger the sensing part 142, so that the sensing part 142 generates an electric signal. Further, the triggering part 141 and the sensing part 142 can be arranged at the inlet and outlet 112, that is, when one of the materials 500 enters or exits the inlet and outlet 112, the triggering part 141 can trigger the sensing part 142, and the sensing part 142 generates an electric signal. Further, in some embodiments, the sensing part 142 is connected with a control terminal, and the electric signal generated by the sensing part 142 is fed back to the control terminal, and the control terminal counts according to the feedback of the electric signal. Further, in some embodiments, the triggering part 141 can adopt a mechanical structure of a dial piece, wherein the dial piece in the structure has three positions, which are a first position, a second position and a third position. When no material 500 passes through the inlet and outlet 112 to enter or exit the storage cavity 111, the dial piece is in the second position. When the material 500 is outputted through the inlet and outlet 112, the material 500 drives the dial piece to rotate when the material 500 is outputted, so that the dial piece moves from the second position to the third position and triggers an electric signal. When the material 500 is completely removed from the inlet and outlet 112, the dial piece returns to the second position. When the material 500 is inputted through the inlet and outlet 112 into the storage cavity 111, the material 500 drives the dial piece to rotate when the material 500 is inputted, so that the dial piece moves from the second position to the first position and triggers another electric signal. When the material 500 is completely inputted from the inlet and outlet 112 into the storage cavity 111, the dial piece returns to the second position. At this time, the control terminal can count according to the two different electric signals. The dial piece can adopt a resilient memory metal material.
[0046] It should be noted that, in the embodiment, the triggering part 141 and the sensing part 142 are arranged, and when one of the materials 500 enters or exits the storage cavity 111, the triggering part 141 can trigger the sensing part 142, so that the sensing part 142 generates an electric signal, so that the control terminal counts according to the generated electric signal, and the feeding mechanism 100 has the counting function, thereby solving the technical problems existing in the prior art.
[0047] In an embodiment, referring to Figure 1 、 Figure 2 、 Figure 3The driving unit 130 is configured as a first elastic telescopic member. Further, the feeding mechanism 100 further comprises a first limiting part 150 and a second elastic telescopic member 160, wherein the first limiting part 150 and the second elastic telescopic member 160 are installed on the storage part 110 and arranged at the inlet and outlet 112. The first limiting part 150 has a first position and a second position relative to the storage part 110. At the first position, the opening degree of the inlet and outlet 112 can be reduced. At the second position, the opening degree of the inlet and outlet 112 can be increased. It should be noted that the first limiting part 150 at the second position increases the opening degree of the inlet and outlet 112, which is compared with the first limiting part 150 at the first position reducing the opening degree of the inlet and outlet 112. The first limiting part 150 is provided with a guide surface 151. When the guide surface 151 is stressed, the first limiting part 150 moves from the first position to the second position and deforms the second elastic telescopic member 160. When the stress on the guide surface 151 is removed, the second elastic telescopic member 160 has a tendency to drive the first limiting part 150 to move from the second position to the first position. It should be noted that during the process of loading the material 500 into the storage cavity 111, the material 500 first contacts the guide surface 151 and gives the guide surface 151 a pressure, so that the guide surface 151 is stressed. When the guide surface 151 is stressed, the first limiting part 150 moves from the first position to the second position and deforms the second elastic telescopic member 160. When the material 500 completely enters the storage cavity 111, the guide surface 151 is not stressed at this time. Then, the first limiting part 150 can move from the second position to the first position under the action of the second elastic telescopic member 160. Specifically, the first limiting part 150 moves from the second position to the first position by restoring the deformation of the second elastic telescopic member 160. When the material 500 completely enters the storage cavity 111, the material 500 can deform the first elastic telescopic member through the receiving part 120. It should be noted that the elastic telescopic member connects the receiving part 120 and the storage part 110. When the elastic telescopic member restores the deformation, the receiving part 120 can be driven to move towards the inlet and outlet 112, so as to push the material 500 on the receiving part 120 towards the inlet and outlet 112. Further, in some embodiments, the first limiting part 150 can move from the first position to the second position by horizontal movement, or can move from the first position to the second position by swinging around an axis.It needs to be further explained that when the PCR plate is used on the pipeline, the PCR plate is taken out from the storage cavity 111 by the mechanical claw 400. Specifically, the mechanical claw 400 can first contact the guide surface 151 when taking out, giving the guide surface 151 pressure, so that the first limiting part 150 moves from the first position to the second position. At this time, the mechanical claw 400 continues to move downward to grab the PCR plate. After completing the grabbing action, the mechanical claw 400 moves upward again. At this time, the PCR plate moves upward with the mechanical claw 400. It needs to be further explained that during the upward movement of the mechanical claw 400, if the guide surface 151 is not under pressure, the second elastic member 160 has a tendency to recover the deformation at this time, so that the first limiting part 150 gradually moves from the second position to the first position. In this process, as the material 500 is taken out, the first elastic member can also drive the receiving part 120 at this time, so that the receiving part 120 moves towards the inlet and outlet 112, thereby pushing the material 500 on the receiving part 120 towards the inlet and outlet 112. In order to limit the remaining material 500 in the storage cavity 111, at this time when the first limiting part 150 gradually moves from the second position to the first position, the first limiting part 150 can slide on the side surface of the material 500. When the material 500 is completely taken out, the first limiting part 150 is in the first position and limits the remaining material 500 in the storage cavity 111, thereby avoiding that the remaining material 500 is lifted. At this time, the first elastic member can drive the material 500 arranged on the receiving part 120 to abut against the first limiting part 150. It needs to be explained that the material 500 in the embodiment is preferably a non-full-skirt PCR plate.
[0048] In an embodiment, with reference to Figure 1 、 Figure 2 、 Figure 3 , the storage part 110 is provided with a mounting cavity 113, and the first limiting part 150 and the second elastic member 160 are arranged in the mounting cavity 113. At the first position, at least part of the structure of the guide surface 151 is arranged outside the mounting cavity 113. In some embodiments, when the first limiting part 150 is in the first position, the guide surface 151 can be completely arranged outside the mounting cavity 113. Further, the first limiting part 150 can move horizontally in the mounting cavity 113, wherein a limiting protrusion 117 (see Figure 3 ) is arranged in the mounting cavity 113. When the first limiting part 150 moves to the first position, the limiting protrusion 117 limits part of the structure of the first limiting part 150 in the mounting cavity 113, so as to avoid the first limiting part 150 from coming out of the mounting cavity 113. That is, when the first limiting part 150 moves to the first position, part of the structure is arranged outside the mounting cavity 113, and another part of the structure is arranged inside the mounting cavity 113.
[0049] In an embodiment, with reference to Figure 1 ,Figure 2 、 Figure 3 , the first limiting part 150 and the second elastic telescopic part 160 are configured as two groups and are respectively arranged on opposite sides of the inlet and outlet 112. It should be noted that when the first limiting part 150 and the second elastic telescopic part 160 are configured as two groups, two opposite first limiting parts 150 provide a more stable support structure, reducing the inclination or instability phenomenon that may be caused by unilateral limiting. When the material 500 enters or exits the storage cavity 111, the two sides of the first limiting part 150 can evenly share the pressure. This not only prolongs the service life of the limiting part, but also reduces the risk of wear or damage caused by excessive local stress. In some embodiments, the first limiting part 150 and the second elastic telescopic part 160 can be configured as one group.
[0050] In an embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 , the first elastic telescopic part and the second elastic telescopic part 160 are configured as springs, but the design is not limited thereto. In some embodiments, the first elastic telescopic part and the second elastic telescopic part 160 can also be configured as tension springs or gas springs. It should be noted that when the driving unit 130 adopts a spring, the cost is relatively low compared with the case where the driving unit 130 adopts an electric telescopic rod.
[0051] In an embodiment, referring to Figure 1 、 Figure 2 、 Figure 3The trigger portion 141 is installed on the receiving portion 120, and the sensing portions 142 are arranged in multiple numbers, and the multiple sensing portions 142 are arranged along the moving path of the receiving portion 120. When one material 500 enters the storage cavity 111, the receiving portion 120 can move a certain distance, and the trigger portion 141 is aligned with one sensing portion 142, so that the sensing portion 142 generates an electrical signal. It can be understood that by arranging multiple sensing portions 142 on the moving path of the receiving portion 120, each time the material 500 enters the storage cavity 111, the receiving portion 120 moves a certain distance and aligns with the corresponding sensing portion 142, thereby generating an electrical signal. In this way, the precise counting of the entering and exiting actions of each PCR plate can be realized. In the embodiment, the trigger portion 141 is configured as a photoelectric shutter; and the sensing portion 142 is configured as a photoelectric switch. In the embodiment, the sensing portion 142 is configured as ten, that is, the storage cavity 111 can store ten materials 500. When ten PCR plates are pressed in, the position of the photoelectric shutter is at the position of the tenth photoelectric switch from the bottom. When one PCR plate is pressed in, the position of the photoelectric shutter is at the position of the first photoelectric switch from the top. When no PCR plate is pressed in, the position of the photoelectric shutter is above the position of the first photoelectric switch, and no photoelectric switch is sensed. Therefore, the counting of the PCR plates is realized by sensing which photoelectric switch is sensed. When the first photoelectric switch is sensed, the number of the PCR plates put in is one. When the tenth photoelectric switch is sensed, the number of the PCR plates put in is ten. When no photoelectric switch is sensed, the number of the PCR plates put in is zero. In some embodiments, the sensing portion 142 can also be configured as five or fifteen, and at this time, the storage cavity 111 can store five materials 500 or fifteen materials 500.
[0052] In an embodiment, referring to Figure 1 , Figure 2 , Figure 3 The storage portion 110 includes a first mounting portion 114 and a second mounting portion 115 connected to each other, and the storage cavity 111 is formed between the first mounting portion 114 and the second mounting portion 115, so that the receiving portion 120 and the driving unit 130 can be conveniently installed in the storage cavity 111. Further, in some embodiments, openings are arranged on both sides of the storage cavity 111.
[0053] In an embodiment, referring to Figure 3The storage cavity 111 is provided with a positioning portion 116, the positioning portion 116 is arranged close to the inlet and outlet 112, the receiving portion 120 is provided with a second limiting portion 121, when the receiving portion 120 moves close to the inlet and outlet 112, the second limiting portion 121 abuts against the positioning portion 116, further, the second limiting portion 121 is configured as a screw, the screw is detachably connected to the receiving portion 120, when the screw abuts against the positioning portion 116, the positioning portion 116 and the screw cooperate to limit the receiving portion 120 in the storage cavity 111, wherein the screw can slide in the opening on both sides of the storage cavity 111 when following the receiving portion 120 to move. Figure 3 The bottom of the opening can also be provided with the positioning portion 116, which is used to limit the stroke when the receiving portion 120 is pressed down, so as to ensure that the number of PCR plates placed in the storage cavity 111 does not exceed the capacity of the feeding mechanism. For example, the feeding mechanism with a capacity of 10 cannot be filled with 11 PCR plates. In addition, the positioning portion 116 below the opening is also used to protect the spring below the receiving portion 120 from being compressed too much, thereby achieving the purpose of protecting the spring.
[0054] The utility model also provides a kind of feeding equipment, referring to Figure 4 、 Figure 5 The feeding equipment includes box body 200 and multiple feeding mechanisms 100, and the specific structure of the feeding mechanism 100 is referred to the above embodiment, since the feeding equipment adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, multiple feeding mechanisms 100 are arranged side by side in the box body 200, the box body 200 is provided with a box opening 210 for feeding materials 500 in and out, and multiple inlet and outlet 112 are arranged corresponding to the box opening 210.
[0055] In an embodiment, referring to Figure 4 、 Figure 5 The feeding equipment further includes a monitoring unit 300, which can monitor the excess materials 500 in the feeding equipment, so as to improve the accuracy of storing materials 500 in the feeding equipment, avoid putting excess materials 500, and thus affect the counting accuracy. If excess materials 500 are monitored, a feedback prompt signal is fed back to prompt the staff to take them away, or cooperate with other material taking equipment to take them away, such as material taking manipulator and material taking suction claw.
[0056] In an embodiment, referring to Figure 4 、 Figure 5The monitoring unit 300 is configured as a reflective photoelectric switch, a signal emitting end of the reflective photoelectric switch is arranged above the inlet and outlet 112, and a distance between the signal emitting end and the inlet and outlet 112 is less than a thickness of the material 500, so as to ensure accurate monitoring. When the reflective photoelectric switch is used, if the signal emitted by the signal emitting end is not blocked, it is proved that no extra material 500 is placed above the inlet and outlet 112, and if the signal emitted by the signal emitting end is blocked, it is proved that extra material 500 is placed above the inlet and outlet 112. However, the design is not limited thereto, and in some embodiments, the monitoring unit can also use a ccd camera to monitor through a visual image.
[0057] The above merely describes exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
