[0065] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0066] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0067] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0068] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0069] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0070] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0071] It should be noted that in biomedical testing and molecular scientific research experiments, there are many types of consumables, and PCR (polymerase chain reaction) reaction plates are just one type of consumables. The container in the consumable plate picking and placing device of this application is used to accommodate multiple consumables in a stacked manner. The consumables are not limited to PCR reaction plates. This application can accommodate various types of consumables that need to be accommodated and perform corresponding picking and placing operations. That is, the PCR reaction plate mentioned in this application is only exemplary, and this application does not limit the types of consumables accommodated.

[0072] With the rapid development of automation technology, automated scientific research equipment and laboratory instruments have been widely used in life sciences, gene sequencing, clinical diagnosis, biomedicine, cell molecular biology, drug screening, medical care, inspection and quarantine and other fields, greatly improving the detection efficiency of biological samples and the accuracy of test results.

[0073] In existing technologies, deep-well plates, microplates, and PCR reaction plates are commonly used consumables in automated testing equipment. They are typically used to hold samples, reagents, or other reactants, and are then used to perform tests and obtain test results. Therefore, how to automatically and continuously supply these consumables to automated testing equipment is a pressing technical challenge in improving the throughput and efficiency of automated testing equipment.

[0074] Furthermore, it should be noted that in the related art, the process of removing and placing consumables requires the joint action of a snap-fit ​​structure and a lifting mechanism. This results in a complex overall structure of the consumable plate removal and placement device in the related art, making it difficult to operate and inconvenient to remove and place consumables. Furthermore, the use of a lifting mechanism inevitably requires a large amount of space in the height direction, resulting in low height space utilization in the consumable plate removal and placement device in the related art, which is restricted by the height direction.

[0075] In addition, it is understandable that since the consumables are stacked, when the consumables themselves are light in weight, or the adsorption force between the contact surfaces of two adjacent consumables is greater than the gravity of the consumables themselves, or the friction between the consumables and the side walls of the mechanism that holds the consumables is greater than the gravity of the consumables themselves, when the lifting mechanism descends, the consumables cannot descend synchronously with the lifting mechanism, resulting in the consumables being suspended in the air and unable to be released smoothly, which is inconvenient for the release of the consumables.

[0076] See Figure 1 、 Figure 2 and Figure 3As shown. The consumable plate picking and placing device 1 provided in one embodiment of the present application includes a container 11 and a movable member 12. The container 11 includes a cavity 111 with an opening, the opening is provided at the bottom of the container 11 along the direction of gravity, and the cavity 111 is used to stack and accommodate multiple consumables 2; the container 11 is provided with notches 112 on opposite sides along a first direction, and the first direction intersects with the direction of gravity of the container 11. Along the direction toward the opening, the multiple consumables 2 are numbered K1, K2, ..., K n-1 , K n , n is a positive integer, and n>1; numbered K n-1 The distance between the consumable material 22 and the plane where the opening is located is greater than the distance between the consumable material 22 and the plane where the opening is located n The distance between the consumable material 21 and the plane where the opening is located. The movable member 12 is rotatably arranged on both sides of the receiving member 11 along the first direction. Figure 3 、 Figure 4 and Figure 5 As shown, the movable member 12 includes a first state and a second state; in the first state, the movable member 12 is inserted into the slot 112, and part of the movable member 12 is located in the cavity 111. The movable member 12 is used to abut against the number K. n The consumable material 21 faces the side of the opening; in the second state, part of the movable member 12 is located outside the cavity 111, and the movable member 12 is used to contact the movable member numbered K n The consumables 21 are separated.

[0077] It should be noted that the first direction is Figure 1 The X direction in the image is the direction of gravity. Figure 1 Along the direction toward the opening, the plurality of consumables 2 are numbered K1, K2, ..., K n-1 , K n , that is, along the gravity direction of the container 11, the plurality of consumables 2 are numbered K1, K2, ..., K n-1 , K n For example, when there are five consumables 2, the consumables 2 are numbered K1, K2, K3, K4, and K5 in sequence, wherein the distance between the consumable 2 numbered K4 and the plane where the opening is located is greater than the distance between the consumable 2 numbered K5 and the plane where the opening is located, that is, the consumable 2 numbered K4 is located above the consumable 2 numbered K5.

[0078] It should be noted that, for the sake of convenience, the above mentioned in this application refers to the above of the container 11 in the direction of gravity, and the below mentioned in this application refers to the below of the container 11 in the direction of gravity.

[0079] On the one hand, see Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the consumable plate picking and placing device 1 provided in one embodiment of the present application automatically releases the consumable 2. Specifically, when the consumable 2 is stored in the container 11, the movable member 12 is in the first state. At this time, the movable member 12 abuts against the number K. n Consumables 21, numbered K n The consumable 21 and the consumable 2 above it are both held in the cavity 111 of the container 11 and cannot move. Further, when it is necessary to release the consumable 2, the movable member 12 is switched to the second state. At this time, the movable member 12 and the consumable member numbered K are connected. n The consumables 21 are separated, and the movable parts 12 are numbered K n The holding force of the consumable material 21 is eliminated, numbered K n The consumable material 21 and the consumable material 2 above it are moved downward by gravity. Then, the movable member 12 is switched back to the first state. At this time, the movable member 12 abuts against the number K n-1 Consumables 22, and numbered K n-1 The consumable material 22 and the consumable material 2 above it are moved upward by a preset distance so that the consumable material numbered K n-1 Consumables 22 and number K n The consumable material 21 is separated and the number K n-1 The consumable 22 and the consumable 2 above it are retained in the cavity 111 of the accommodating member 11.

[0080] It is understood that when the movable member 12 is initially in the first state, the movable member 12 and the movable member numbered K n The consumable material 21 abuts against the movable member 12, and as the movable member 12 switches from the first state to the second state, the movable member 12 gradually abuts against the consumable material 21. n The consumable material 21 is separated, at this time, the number is K n The consumables 21 fall naturally under the action of gravity. Due to the pre-control of the height between the movable part 12 and the bottom of the container 11 and the height between the consumables 2 and the bottom of the container 11, when the number K n When the consumable material 21 is subjected to gravity, only the consumable material numbered K is allowed to n The consumable material 21 falls to below the level of the movable member 12, and the consumable material numbered K n-1 The consumable material 22 falls to above the level of the movable member 12. n After the consumable material 21 is separated from the movable member 12 and falls, the movable member 12 is switched from the second state to the first state. At this time, the movable member 12 and the movable member numbered K n-1 The consumable material 22 abuts and makes the number K n-1 Consumables 22 and the consumables above it and numbered K n The consumables 21 are separated, thereby achieving the nThe consumables 21 are released from the container 11. When it is necessary to continue to release the consumables numbered K n-1 When the consumable material 22 is supplied, the movable member 12 is switched from the first state to the second state, and the movable member 12 is connected to the movable member numbered K n-1 Consumables 22 are separated and numbered K n-1 The consumable material 22 falls under the gravity, and then the movable member 12 is switched from the second state to the first state, so that the movable member 12 is re-connected with the number K n-2 The consumable material 2 is abutted, and the movable member 12 is switched between the first state and the second state in sequence to realize the n-1 The consumables 22 are released from the receiving member 11. It is understandable that it is only necessary to control the movable member 12 to switch between the first state and the second state to release the consumables numbered K in sequence. n , K n-1 ,......,K2,K1 consumables 2.

[0081] On the other hand, see Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the consumable plate taking and placing device 1 provided in one embodiment of the present application automatically collects the consumables 2. Specifically, when the movable member 12 is in the first state, the movable member 12 abuts against the number K n-2 Consumables 2, numbered K n-2 The consumable 2 and the consumable 2 above it are both held in the cavity 111 of the container 11 and cannot move. n-1 Consumables 22 arrive at number K n-2 When the movable member 12 is in the preset position below the consumable material 2, the movable member 12 is switched to the second state. At this time, the movable member 12 and the movable member numbered K n-2 The consumables 2 are separated, and the movable parts 12 pairs are numbered K n-2 The holding force of consumable 2 is eliminated, numbered K n-2 Consumable 2 and the consumable 2 above it fall to the position numbered K under the action of gravity. n-1 On the consumable material 22. Further, the movable member 12 is switched back to the first state. At this time, the movable member 12 abuts against the consumable material numbered K. n-1 Consumables 22, and numbered K n-1 The consumable material 22 and the consumable material 2 above it are moved upward by a preset distance, and the consumable material numbered K n-1 The consumable 22 and the consumable 2 above it are retained in the cavity 111 of the accommodating member 11.

[0082] It is understood that when the movable member 12 is initially in the first state, the movable member 12 and the movable member numbered K n-2 The consumable material 2 is abutted, numbered K n-1Consumables 22 arrive at number K n-2 After the movable member 12 is moved to the preset position below the consumable material 2, the movable member 12 gradually moves away from the consumable material 2 and moves to the preset position below the consumable material 2. n-2 The consumables 2 are separated and numbered as K n-2 Consumable 2 continues to move downward under the action of gravity and descends to the position numbered K n-1 Then, the movable member 12 is switched from the second state to the first state. During the switching and rotating process, the movable member 12 is connected to the consumable material 22. n-1 The consumable material 22 gradually abuts, and then as the movable part 12 moves, the consumable material numbered K n-1 Consumable material 22 moves upward, thereby n-1 The consumable material 22 and the consumable material 2 above it are retained in the cavity 111 of the container 11, thereby achieving the n-1 The consumables 22 are collected into the container 11. Further, when it is necessary to continue to collect the consumables numbered K n When the consumable material 21 is loaded into the receiving part 11, it is only necessary to switch the movable part 12 between the first state and the second state in sequence, so that the consumable material numbered K can be collected. n It is understandable that it is only necessary to control the movable member 12 to switch between the first state and the second state, so that the consumables numbered K1, K2, ..., K n-1 , K n Consumables 2.

[0083] The consumable plate picking and placing device provided in the embodiment of the present application realizes the release and collection of consumables through the different forms of the movable part 12. Specifically, the movable part 12 with the first form is used to release the consumables, that is, when the movable part 12 switches from the first state to the second state, all consumables fall to the preset position under the action of gravity, and then when the movable part 12 switches from the second state to the first state, the movable part 12 carries the consumables located above and adjacent to the lowest consumable; the movable part 12 with the second form is used to collect the consumables, that is, when the movable part 12 switches from the first state to the second state, all consumables fall to the consumables placed at the preset position under the action of gravity, and then when the movable part 12 switches from the second state to the first state, the movable part 12 carries the consumables located at the lowest. The consumable plate picking and placing device provided in the embodiment of the present application can have a movable part 12 of any of the above forms, or can have movable parts 12 of both forms at the same time, which will not be repeated here.

[0084] Since the present application does not require the provision of additional auxiliary structures such as a snap structure and a lifting structure during the process of taking and placing the consumables 2, it only requires the provision of a movable part 12, and by changing the different states of the movable part 12, the consumables 2 can be released or collected. On the one hand, the consumables can be continuously and automatically released or collected, thereby improving the efficiency of taking and placing the consumables; on the other hand, the overall structure of the consumable plate taking and placing device 1 of the present application is simple, and does not require more space in the height direction, thereby improving the space utilization rate of the consumable plate taking and placing device 1.

[0085] It is understandable that in the process of releasing consumables 2, the application n When the consumable material 21 is separated from the movable part 12, the number is K n The consumables 21 and the consumables 2 above it are stacked in sequence along the height direction of the container 11. By switching the movable member 12 back to the first state, at this time, the movable member 12 abuts against the number K n-1 Consumables 22, that is, at this time, by switching the state of the movable member 12, the number K n-1 Consumables 22 and number K n The consumables 21 are separated, thereby avoiding the phenomenon that the adjacent consumables 2 cannot be separated or released due to factors such as gravity and friction. That is, by switching the different states of the movable member 12, one of the adjacent consumables 2 can be easily released, which facilitates the release of the consumables 2.

[0086] In some embodiments, see Figure 1 and Figure 2 As shown, the consumable plate taking and placing device 1 further includes a first driving member 14 connected to the movable member 12, and used for driving the movable member 12 to switch between the first state and the second state.

[0087] In this way, the movement of the movable member 12 can be controlled by the first driving member 14, thereby changing the state of the movable member 12. By improving the efficiency of changing the movement state of the movable member 12, the placement efficiency of the consumable plate placement device 1 is improved.

[0088] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 As shown, the movable member 12 includes a first movable unit 121 and a second movable unit 122, and the first movable unit 121 and the second movable unit 122 are respectively arranged on both sides of the accommodating member 11 along the first direction; the first driving member 14 includes a first driving unit and a second driving unit, the first driving unit is connected to the first movable unit 121, and is used to drive the first movable unit 121 to switch between the first state and the second state; the second driving unit is connected to the second movable unit 122, and is used to drive the second movable unit 122 to switch between the first state and the second state.

[0089] In this way, the first movable unit 121 and the second movable unit 122 can be driven respectively by the first drive unit and the second drive unit. On the one hand, the overall driving force of the first drive member 14 can be reduced by the first drive unit and the second drive unit, thereby preventing the first drive member 14 from bearing a large driving load, thereby increasing the service life of the first drive member 14. On the other hand, the first movable unit 121 and the second movable unit 122 can be driven and controlled separately to achieve asynchronous motion, thereby acting on different parts of the consumables 2, thereby improving the flexible adjustment of different states of the movable member 12 and improving the stability of the consumables.

[0090] In some embodiments, see Figure 2 As shown, the first driving member 14 includes a driving motor 141, a first rotating unit 142, a connecting member 143 and a second rotating unit (not shown in the figure), the first rotating unit 142 is connected to the output shaft of the driving motor 141, and the connecting member 143 is connected to one end of the first rotating unit 142 away from the driving motor 141 and the second rotating unit; the movable member 12 includes a first movable unit 121 and a second movable unit 122, and the first movable unit 121 and the second movable unit 122 are respectively arranged on both sides of the accommodating member 11 along the first direction; the first movable unit 121 is connected to the first rotating unit 142, and the second movable unit 122 is connected to the second rotating unit.

[0091] In this way, in the process of the first driving member 14 driving the first movable unit 121 and the second movable unit 122, since the connecting member 143 is connected to the end of the first rotating unit 142 away from the driving motor 141 and the second rotating unit, the first movable unit 121 is connected to the first rotating unit 142, and the second movable unit 122 is connected to the second rotating unit. Therefore, under the drive of the driving motor 141, the first rotating unit 142 drives the first movable unit 121 to move, and at the same time, the second rotating unit synchronously drives the second movable unit 122 to move, thereby ensuring that the first movable unit 121 and the second movable unit 122 move synchronously under the drive of the driving motor 141. By controlling the movement of the driving motor 141, the consumables 2 can be taken in and placed, thereby improving the efficiency of taking in and placing the consumables.

[0092] Optionally, the first rotating unit 142 is meshedly connected to the first movable unit 121, and the axis of the first rotating unit 142 is perpendicular to the axis of the first movable unit 121; and / or the second rotating unit is meshedly connected to the second movable unit 122, and the axis of the second rotating unit is perpendicular to the axis of the second movable unit 122.

[0093] In this way, the movement directions of the first rotating unit 142 and the first movable unit 121 can be changed through the meshing connection, thereby converting movement in different directions into the movement direction required by the first movable unit 121. This can avoid the first movable unit 121 and the first rotating unit 142 extending in one direction, thereby wasting space in that direction, and can improve the space utilization rate within the consumable plate picking and placing device 1. Similarly, the movement directions of the second rotating unit and the second movable unit 122 can be changed through the meshing connection, thereby converting movement in different directions into the movement direction required by the second movable unit 122. This can avoid the second movable unit 122 and the second rotating unit extending in one direction, thereby wasting space in that direction, and can further improve the space utilization rate within the consumable plate picking and placing device 1.

[0094] In some embodiments, the first movable unit 121 and the second movable unit 122 are both one, and the first movable unit 121 and the second movable unit 122 are respectively arranged on both sides of the accommodating member 11 along the first direction; wherein, along the projection direction of any side wall of the accommodating member 11, the projections of the first movable unit 121 and the second movable unit 122 do not overlap.

[0095] In this way, only one first movable unit 121 and one second movable unit 122 are required to implement the operation of taking and placing the consumables 2. On the one hand, this can reduce the production cost of the internal components of the consumable plate taking and placing device 1, thereby reducing the production cost of the consumable plate taking and placing device 1. On the other hand, it can further simplify the overall structure of the consumable plate taking and placing device 1, making it easier to take and place the consumables 2.

[0096] In some embodiments, there are multiple first movable units 121 and multiple second movable units 122, and the multiple first movable units 121 and the multiple second movable units 122 are respectively arranged on both sides of the accommodating member 11 along the first direction, and multiple first movable units 121 are arranged on one side of the accommodating member 11 along the first direction, and multiple second movable units 122 are arranged on the other side of the accommodating member 11 along the first direction; wherein, the multiple first movable units 121 are connected to each other, and the multiple second movable units 122 are connected to each other.

[0097] In this way, during the abutment between the movable part 12 and the consumable material 2, the abutment position between the movable part 12 and the consumable material 2 can be increased by multiple first movable units 121 and multiple second movable units 122, thereby improving the stability and reliability of the consumable material 2 during the taking and placing process.

[0098] In some embodiments, see Figure 6 and Figure 10As shown, the movable member 12 includes a first rotating portion 123 and a first protruding portion 124. The first rotating portion 123 is located outside the cavity 111; the first protruding portion 124 is connected to one side of the first rotating portion 123. In the first state, the first protruding portion 124 is located inside the cavity 111 and is used to abut against the contact numbered K. n The consumable material 21 faces the side of the opening; in the second state, the first protrusion 124 is located outside the cavity 111, for use with the number K n The consumables 21 are separated.

[0099] Specifically, during the process of releasing the consumable material 2, the movable member 12 is in the first state. At this time, the first protrusion 124 is located in the cavity 111 and is aligned with the first protrusion 124 numbered K. n The consumable material 21 is abutted, numbered K n The consumables 21 and the consumables 2 above it cannot move. Further, the movable member 12 is switched from the first state to the second state. At this time, the first protrusion 124 follows the first rotating portion 123 to rotate outside the cavity 111. The first protrusion 124 and the consumables numbered K n Consumables 21 are separated and numbered K n The consumables 21 fall down due to its own gravity. The movable member 12 is switched from the second state to the first state, and the first protrusion 124 follows the first rotating portion 123 to rotate back into the cavity 111. At this time, the first protrusion 124 is re-engaged with the number K n-1 The consumables 22 abut, thereby collecting can release the number K n Consumables 21. When it is necessary to continue to release the number K n-1 When the consumable material 22 is released, it is only necessary to switch the first protrusion 124 between the first state and the second state in sequence, so as to release the consumable material numbered K n-1 It is understandable that when performing the operation of continuously releasing multiple consumables 2, it is only necessary to control the movable member 12 to switch between the first state and the second state in sequence, so that the consumables numbered K can be released in sequence. n , K n-1 ,......,K2,K1 consumables 2.

[0100] During the process of collecting the consumables 2, the movable member 12 is in the first state. At this time, the first protrusion 124 is located in the cavity 111 and is aligned with the first protrusion 124 numbered K. n-2 The consumable material 2 is abutted, numbered K n-2 The consumables 2 and the consumables 2 above it cannot move. Further, the movable member 12 is switched from the first state to the second state. At this time, the first protrusion 124 follows the first rotating portion 123 to rotate outside the cavity 111. The first protrusion 124 and the consumables numbered K n-2 The consumables 2 are separated, because the number is K n-2Place the K number below the consumable 2 n-1 Consumables 22, thus numbered K n-2 The consumables 2 cannot be affected by gravity and continue to move downward. The movable member 12 is switched from the second state to the first state, and the first protrusion 124 follows the first rotating portion 123 to rotate back into the cavity 111. At this time, the first protrusion 124 is re-engaged with the number K n-1 The consumable material 22 gradually abuts, and then as the first rotating part 123 moves, the consumable material numbered K n-1 The consumable material 22 moves upward, so that the consumable material numbered K can be collected. n-1 Consumables 22. When continuing to collect number K n When operating the consumables 21, it is only necessary to switch the first protrusion 124 between the first state and the second state in sequence, so that the consumables numbered K can be collected. n It is understandable that when it is necessary to continuously collect multiple consumables 2, it is only necessary to control the movable member 12 to switch between the first state and the second state in sequence, so that the consumables numbered K1, K2, ..., K n-1 , K n Consumables 2.

[0101] In this way, on the one hand, different functions can be achieved for different working parts of the movable part 12, thereby improving the reliability of the movable part 12 during operation. On the other hand, it is understandable that the first protrusion 124, as the main force-bearing part, can be made of a material with greater hardness and wear resistance than the first rotating part 123, thereby increasing the service life of the first protrusion 124, thereby increasing the service life of the movable part 12, and ultimately increasing the service life of the consumable plate picking and placing device 1.

[0102] In some embodiments, see Figure 1 and Figure 2 As shown, the consumable plate retrieval device 1 further includes a transmission member 13. The transmission member 13 is disposed below the gravity of the container 11, with a portion of the transmission surface of the transmission member 13 facing the opening. The transmission member 13 is used to drive the consumables 2. And / or, the container 11 further includes a support base 113. The support base 113 is disposed on one side of the bottom of the container 11 along the gravity direction.

[0103] Thus, in the process of releasing the consumables 2, when the movable member 12 is in the first state, the movable member 12 can be separated from the movable member 12 by the transmission member 13. n In the process of collecting consumables 2, the movable member 12 is in the first state, and the transmission member 13 can be driven by the number K n The consumable material 21 moves, thereby placing the number K nThe consumables 21 are moved to a preset position below the receiving member 11. Since the consumables 2 can be driven by the transmission member 13 during the process of taking and placing the consumables 2, the consumables 2 can be easily taken and placed. At the same time, the consumables 2 can be driven by the transmission member 13 to move, which can improve the efficiency of the process of taking and placing the consumables 2.

[0104] Furthermore, on the one hand, the support base 113 can support the main body of the container 11, thereby improving the stability of the container 11. On the other hand, due to the structure of the support base 113, a height difference is formed at the position of the support base 113 relative to the opening, so that during the process of taking and placing the consumables 2, the consumables 2 to be taken and placed can be pre-set at this height position, thereby making the process of taking and placing the consumables 2 smoother.

[0105] Another embodiment of the present application provides a consumable plate picking and placing device 1, comprising a container 11 and a movable member 12. The container 11 comprises a cavity 111 having an opening, the opening being provided at the bottom of the container 11 along the direction of gravity, and the cavity 111 being used to stack and accommodate a plurality of consumables 2; the container 11 is provided with notches 112 on opposite sides along a first direction, the first direction intersecting with the direction of gravity of the container 11. Along the direction toward the opening, the plurality of consumables 2 are numbered K1, K2, ..., K n-1 , K n , n is a positive integer, and n>1; numbered K n-1 The distance between the consumable material 22 and the plane where the opening is located is greater than the distance between the consumable material 22 and the plane where the opening is located n The distance between the consumable material 21 and the plane where the opening is located. The movable member 12 is rotatably arranged on both sides of the accommodating member 11 along the first direction. The movable member 12 includes a second protruding portion 125, a second rotating portion 126 and a third protruding portion 127, and the second protruding portion 125 and the third protruding portion 127 are respectively connected to both sides of the second rotating portion 126. The movable member 12 includes a third state, a fourth state and a fifth state. In the third state, the second protruding portion 125 is passed through the notch 112 and is located in the cavity 111. The second protruding portion 125 is used to abut against the projection numbered K n In the fourth state, the third protrusion 127 is provided in the slot 112, located in the cavity 111, the third protrusion 127 is used to abut the number K n In the fifth state, the second protrusion 125 and the third protrusion 127 are located outside the cavity 111, and the second protrusion 125 and the third protrusion 127 are used to connect with the number K n The consumables 21 are separated.

[0106] It should be noted that when the movable member 12 is provided with only the first rotating portion 123 and the first protruding portion 124, in the process of releasing the consumable 2, when the movable member 12 is in the second state, the movable member 12 and the movable member numbered Kn Consumables 21 are separated and numbered K n After the consumable material 21 falls under the action of gravity, the movable member 12 can be connected with the movable member numbered K when it switches back to the first state. n-1 Therefore, the movable member 12 is required to include a protrusion having a preset first shape to ensure that when the movable member 12 switches to the first state, the contact point between the protrusion of the movable member 12 and the consumable is located at the position numbered K n Consumables 21 and number K n-1 Between the consumables 22, thus numbering K n Consumables 21 and number K n-1 The consumables 22 are separated and supported by the number K n-1 Consumables 22 move upward; in the process of collecting consumables 2, in the first state, the movable member 12 carries the number K n-2 Consumables 2, numbered K n-1 The consumable material 22 is placed on the n-2 When the movable member 12 switches to the second state, the number is K n-2 Consumable 2 falls to the K n-1 The consumable material 22, at this time, the movable member 12 is required to include a protrusion with a preset second shape to ensure that when the movable member 12 switches to the first state, the contact point between the protrusion of the movable member 12 and the consumable material is located at the position numbered K n-1 Consumables 22, and the support number is K n-1 The consumable material 22 moves upward. It can be understood that the difference between the preset second shape of the protrusion and the preset first shape at least includes that the preset second shape is longer than the preset first shape.

[0107] Furthermore, by configuring the movable member 12 to include the second protruding portion 125 , the second rotating portion 126 and the third protruding portion 127 , the movable member 12 includes a third state, a fourth state and a fifth state.

[0108] During the release of consumables 2, refer to Figure 11 、 Figure 12 and Figure 13 As shown, the movable member 12 is in the third state. At this time, the second protrusion 125 is located in the cavity 111 and is aligned with the second protrusion 125 numbered K. n The consumable material 21 is abutted, numbered K n The consumable 21 and the consumable 2 above it cannot move. Further, the movable member 12 is switched from the third state to the fifth state. At this time, the second protrusion 125 rotates to the outside of the cavity 111, and the second protrusion 125 and the consumable number K n Consumables 21 are separated and numbered K nThe consumables 21 fall down due to its own gravity. The movable member 12 is switched from the fifth state to the third state, and the second protrusion 125 follows the second rotating portion 126 to rotate back into the cavity 111. At this time, the second protrusion 125 is re-engaged with the number K n-1 The consumable material 22 abuts, thereby conveniently releasing the number K n Consumables 21. When it is necessary to continue to release the number K n-1 When the consumable material 22 is loaded, it is only necessary to switch the second protrusion 125 between the third state and the fifth state in sequence, so as to release the consumable material numbered K. n-1 It is understandable that when it is necessary to release multiple consumables 2 continuously, it is only necessary to control the movable member 12 to switch between the third state and the fifth state in sequence, so that the consumables numbered K can be released in sequence. n , K n-1 ,......,K2,K1 consumables 2.

[0109] During the collection of consumables 2, refer to Figure 11-Figure 15 As shown, the movable member 12 is in the third state. At this time, the second protrusion 125 is located in the cavity 111 and is aligned with the second protrusion 125 numbered K. n-2 The consumable material 2 is abutted, numbered K n-2 The consumables 2 and the consumables 2 above it cannot move. Further, the movable member 12 is switched from the third state to the fifth state. At this time, the second protrusion 125 follows the second rotating portion 126 to rotate outside the cavity 111. The second protrusion 125 and the consumables numbered K n-2 Consumables 2 are separated and numbered K n-2 The consumables 2 continue to move downward under the action of gravity until they contact the bottom of the consumable plate pick-up and placement device 1. The movable member 12 is switched from the fifth state to the fourth state, and the third protrusion 127 follows the second rotating portion 126 to rotate into the cavity 111. At this time, the third protrusion 127 and the number K n-1 The consumable material 22 gradually abuts, and then as the second rotating part 126 moves, the consumable material numbered K n-1 The consumable material 22 moves upward, so that the consumable material numbered K can be easily collected. n-1 Consumables 22. When you need to continue to collect number K n When the consumable material 21 is collected, it is only necessary to switch the third protrusion 127 between the fourth state and the fifth state in sequence, so that the consumable material numbered K can be collected. n It is understandable that when it is necessary to collect multiple consumables 2 continuously, it is only necessary to control the movable member 12 to switch between the fourth state and the fifth state in sequence, so that the consumables numbered K1, K2, ..., K n-1 , K n Consumables 2.

[0110] In this way, the second protrusion 125 and the third protrusion 127 can be used to switch the movable part 12 between the third state, the fourth state and the fifth state, so that the consumable plate picking and placing device is not restricted by the influence of the relative height between the movable part 12 and the consumable 2, so that the consumable plate picking and placing device 1 can realize the function of releasing the consumable 2 and the function of collecting the consumable 2.

[0111] In some embodiments, the distance between the protruding point of the second protruding portion 125 and the center point of the second rotating portion 126 is smaller than the distance between the protruding point of the third protruding portion 127 and the center point of the second rotating portion 126 .

[0112] In this way, since the distance between the protruding point of the second protruding part 125 and the center point of the second rotating part 126 is smaller than the distance between the protruding point of the third protruding part 127 and the center point of the second rotating part 126, the relative height of the movable part 12 relative to the consumable 2 can be affected by the difference between the distance between the protruding point of the third protruding part 127 and the center point of the second rotating part 126 and the distance between the protruding point of the second protruding part 125 and the center point of the second rotating part 126, so that the consumable plate picking and placing device 1 can realize both the function of releasing the consumable 2 and the function of collecting the consumable 2.

[0113] In some embodiments, the consumable plate taking and placing device further includes a second driving member. The second driving member is connected to the movable member 12 and is used to drive the movable member 12 to switch between the third state, the fourth state and the fifth state.

[0114] In this way, the second driving member can be used to control the movement of the movable member 12, thereby changing the state of the movable member 12. On the one hand, the second driving member can be directly controlled, that is, the state of the movable member 12 can be changed, which can simplify the operation. On the other hand, controlling the movement of the movable member 12 by the second driving member can improve the efficiency of changing the movement state of the movable member 12, thereby improving the picking and placing efficiency of the consumable plate picking and placing device 1.

[0115] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
