[0047] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0048] Please refer to Figure 1-Figure 5 , this embodiment provides a stacking mechanism 200, the stacking mechanism 200 includes a main frame 210, a plurality of pallets 220 and a plurality of material storage units 230;

[0049] The plurality of support plates 220 are all slidably connected to the main frame 210, and the plurality of support plates 220 are arranged parallel to each other;

[0050] Each pallet 220 is connected to at least one material storage unit 230; each material storage unit 230 includes a material chute 231, a first limit block 232, a second limit block 233, a rotating belt 234 and a first driving unit 235; the material chute 231 is connected to the pallet 220, and the material chute 231 extends along the sliding direction of the pallet 220; the rotating belt 234 and the first driving unit 235 are both connected to the pallet 220, and the rotating belt 234 extends along the sliding direction of the pallet 220 and is transmission-connected to the first driving unit 235; the first limit block 232 is connected to the rotating belt 234, and the second limit block 233 is connected to the pallet 220;

[0051] Among them, the first driving unit 235 is used to drive the rotating belt 234 to rotate, so as to drive the first limit block 232 to abut against the material 10 close to it in the material chute 231, and then drive all the materials 10 in the material chute 231 to move toward the direction of the second limit block 233, and make the material 10 close to the second limit block 233 abut against the second limit block 233.

[0052] It should be noted that, in this embodiment, the stacking mechanism 200 is used to store the Tip header box for illustration, that is, the material 10 in this embodiment is the Tip header box; in other embodiments of the present invention, the stacking mechanism 200 can also be used to store other types of materials 10.

[0053] It should also be noted that, in the present embodiment, when placing materials 10 into each material storage unit 230 on each pallet 220, the size specifications of the materials 10 stored in each material storage unit 230 may be different, that is, each pallet 220 or each material storage unit 230 is used to store materials 10 of a certain size specification, so that the materials 10 can be classified and stored to facilitate the retrieval and storage of the materials 10.

[0054] Please refer to Figure 1-Figure 5 , the working principle of the stacking mechanism 200 is:

[0055] The stacking mechanism 200 includes a main frame 210, a plurality of pallets 220 and a plurality of material storage units 230; the plurality of pallets 220 are slidably connected to the main frame 210, and the plurality of pallets 220 are arranged parallel to each other; each pallet 220 is connected to at least one material storage unit 230; each material storage unit 230 is used to store a plurality of materials 10, and thus, through such an arrangement, the material storage unit 230 can be arranged on the pallet 220, and in conjunction with the sliding of the pallet 220 relative to the main frame 210, the material 10 can be stored and received when the pallet 220 slides into the main frame 210, and the pallet 220 slides out of the main frame 210, which is convenient for the staff to take out the material 10 stored in the pallet 220, or put the material 10 into the pallet 220 in the sliding out state;

[0056] When setting the material storage unit 230, since the working principle and purpose of each material storage unit 230 are the same, the working principle of one of the material storage units 230 is used as an example for explanation below. Each material storage unit 230 includes a material chute 231, a first limit block 232, a second limit block 233, a rotating belt 234 and a first driving unit 235; the material chute 231 is connected to the pallet 220, and the material chute 231 extends along the sliding direction of the pallet 220; the rotating belt 234 and the first driving unit 235 are both connected to the pallet 220. The rotating belt 234 extends along the sliding direction of the support plate 220 and is connected to the first driving unit 235; the first limit block 232 is connected to the rotating belt 234, and the second limit block 233 is connected to the support plate 220; wherein the first driving unit 235 is used to drive the rotating belt 234 to rotate, so as to drive the first limit block 232 to abut against the material 10 close to the material chute 231, and then drive all the materials 10 in the material chute 231 to move toward the direction of the second limit block 233, and make the material 10 close to the second limit block 233 abut against the second limit block 233.

[0057] Thus, when storing the material 10 in the material storage unit 230, the pallet 220 is slid out of the main frame 210 so that at least part of the material chute 231 is located outside the main frame 210, so as to facilitate the placement of the material 10; then, the material 10 is placed in the open material chute 231, and the pallet 220 is pushed into the main frame 210, so that the placement and storage of the material 10 can be completed; in addition, after the material 10 is placed in the material chute 231, the rotating belt 234 is driven to rotate by the first driving unit 235 to drive the material 10 to be stored. The first limit block 232 is moved to abut against the adjacent material 10 in the material chute 231, thereby driving all the materials 10 in the material chute 231 to move toward the second limit block 233, and making the materials 10 adjacent to the second limit block 233 abut against the second limit block 233. Thus, multiple materials 10 in the same material chute 231 can be orderly and neatly discharged under the joint action of the first limit block 232 and the second limit block 233, so that the stacking mechanism 200 can store the materials 10 in an orderly manner.

[0058] It should be noted that, from the above content, it can be seen that when the first limit block 232 moves toward the direction of the second limit block 233 under the action of the rotating belt 234 to abut against the material 10 in the material chute 231 to play the role of sorting the material 10, in order to make the material 10 placed in the material chute 231 be located between the first limit block 232 and the second limit block 233, therefore, when the pallet 220 slides out of the main frame 210, the first limit block 232 moves in the direction in which the pallet 220 slides out under the driving action of the rotating belt 234, so that the first limit block 232 and the second limit block 233 are located at the two ends of the pallet 220 along the sliding direction of the pallet 220, so that the subsequently placed materials 10 are all located between the first limit block 232 and the second limit block 233.

[0059] In summary, the stacking mechanism 200 has a simple structure and is easy to use. It can improve the efficiency of storing materials 10 and simplify the action of storing the materials 10. It can also organize the internal materials 10 so that the materials 10 can be arranged in order.

[0060] Furthermore, in the present embodiment, while storing the material 10, in order to facilitate counting of the stored material 10, the material storage unit 230 also includes a counter, which is used to detect the length of the rotating belt 234 between the first limit block 232 and the second limit block 233, or to detect the distance between the first limit block 232 and the second limit block 233, and calculate the amount of material 10 in the material chute 231 according to the length or distance.

[0061] Specifically, in the process of calculating the amount of material 10 in the material chute 231 based on the length or distance, it is necessary to compare the length of the rotating belt 234 between the first limit block 232 and the second limit block 233 or the distance between the first limit block 232 and the second limit block 233 with the size of the stored material 10 along the extension direction of the material chute 231, so as to calculate the amount of material 10 in the material chute 231.

[0062] It should be noted that when calculating the amount of material 10 in the material chute 231 based on the length of the rotating belt 234 between the first limit block 232 and the second limit block 233 or the distance between the first limit block 232 and the second limit block 233, in order to calculate the length of the rotating belt 234 between the first limit block 232 and the second limit block 233 or the distance between the first limit block 232 and the second limit block 233, the sliding distance of the driving rotating motor along the extension direction of the material chute 231 can be calculated, and a distance sensor or a grating sensor or other structures can also be set. Since the aforementioned distance sensor or grating sensor or other structures are prior art, they will not be repeated here.

[0063] In this embodiment, in order to increase the storage capacity of the stacking mechanism 200, each pallet 220 is connected to two material storage units 230, and the two material storage units 230 are arranged side by side. In other embodiments of the present invention, each pallet 220 may be connected to more than two material storage units 230.

[0064] Please refer to Figure 1-Figure 5 In the present embodiment, when the material chute 231 is set, the function of the material chute 231 is to guide the material 10 to be stored along the sliding direction of the pallet 220. Therefore, in order to form the material chute 231, each material storage unit 230 includes two baffles 236, and the two baffles 236 extend along the sliding direction of the pallet 220. The two baffles 236 are arranged at intervals, and the area between the two baffles 236 forms a material chute 231 where the material 10 exists and for the material 10 to slide.

[0065] Based on the above structural setting, in order to facilitate taking out the material 10 on the pallet 220 or putting the material 10 into the pallet 220, the stacking mechanism 200 also includes a plurality of second drive units 241, and the plurality of second drive units 241 are connected to the main frame 210, and the plurality of second drive units 241 are in one-to-one transmission connection with the plurality of pallets 220, and each second drive unit 241 is used to drive the corresponding pallet 220 to slide out of the main frame 210 or slide into the main frame 210. Therefore, when it is necessary to take out the material 10 on the pallet 220 or put the material 10 into the pallet 220, the corresponding second drive unit 241 drives the corresponding pallet 220 to slide relative to the main frame 210, so that the material storage unit 230 on the pallet 220 can slide out of or into the main frame 210.

[0066] For further information, please refer to Figure 1-Figure 8 In this embodiment, based on the above structure, in order to facilitate the release of the material 10 in the material chute 231, the material 10 in the material chute 231 can be pushed out of the material chute 231 under the action of the first limit block 232. Such a release method requires the first driving unit 235 to drive the rotating belt 234 to rotate, so as to drive the first limit block 232 to move in the direction of the second limit block 233. At the same time, the position of the second limit block 233 needs to be adjusted so that the second limit block 233 opens the inner end of the material 10 slider, that is, the second limit block 233 is cancelled. The limiting effect of the material 10 in the material chute 231; it should be noted that along the sliding direction of the support plate 220 relative to the main frame 210, the end of the support plate 220 that first slides into the main frame 210 is the inner end of the support plate 220 and the material chute 231;

[0067] Therefore, in order to enable the second limit block 233 to move relative to the material chute 231 to open the inner end of the slide block of the material 10, each material storage unit 230 includes a limit seat 237 and an elastic member 238, the second limit block 233 is slidably connected to the limit seat 237, and the second limit block 233 has a first position located at the inner end of the material chute 231 and abutting against the material 10 in the material chute 231, and a second position opening the inner end of the material chute 231; the elastic member 238 is connected to the limit seat 237 and the second limit block 233, and the elastic member 238 is used to make the second limit block 233 have a tendency to move from the first position to the second position;

[0068] That is, when the second limit block 233 is subjected to an external force that overcomes the elastic member 238 and slides relative to the limit seat 237 under the action of the external force, the second limit block 233 can move to the first position and be located at the inner end of the material chute 231 and is used to abut against the material 10 in the material chute 231; and when the second limit block 233 is only subjected to the force of the elastic member 238, the second limit block 233 can move from the first position to the second position under the action of the elastic force to open the inner end of the material chute 231.

[0069] In summary, the stacking mechanism 200 further includes a limiting frame 242, a transmission rod 243, a third driving unit 244 and a plurality of third limiting blocks 245; the limiting frame 242 is connected to the main frame body 210, the transmission rod 243 is movably connected to the limiting frame 242, the third driving unit 244 is connected to the limiting frame 242, and is transmission-connected to the transmission rod 243; the plurality of third limiting blocks 245 are all connected to the transmission rod 243, and the plurality of third limiting blocks 245 correspond one-to-one to the plurality of second limiting blocks 233;

[0070] Among them, the third driving unit 244 is used to drive the transmission rod 243 to move relative to the limit frame 242 so that each third limit block 245 is abutted against the corresponding second limit block 233, and the corresponding second limit block 233 overcomes the elastic force of the elastic member 238 and moves to the first position, or each third limit block 245 is disengaged from the corresponding second limit block 233, and the corresponding second limit block 233 moves to the second position under the action of the elastic force of the elastic member 238.

[0071] Therefore, by driving the transmission rod 243 to move relative to the limit frame 242 through the third driving unit 244, multiple third limit blocks 245 can be moved relative to the main frame 210, and then each third limit block 245 can be moved relative to the corresponding second limit block 233, and each third limit block 245 can be moved to a position that is abutted against the corresponding second limit block 233, and through the abutment between each third limit block 245 and the corresponding second limit block 233, each corresponding second limit block 233 overcomes the elastic force of the elastic member 238 and moves from the second position to the first position; and when each third limit block 245 moves to a position where it is disengaged from the abutment with the corresponding second limit block 233, the second limit block 233 is only subjected to the force of the elastic member 238. At this time, the second limit block 233 will move from the first position to the second position under the action of the elastic member 238.

[0072] For further information, please refer to Figure 1-Figure 13In this embodiment, the stacking mechanism 200 also includes a lifting unit 250, which is located on the same side of the main frame 210 as the plurality of second limit blocks 233, and the lifting unit 250 is used to receive the material 10 pushed out by the first limit block 232 in one of the material chutes 231 when the second limit block 233 is in the second position.

[0073] Specifically, the lifting unit 250 includes a mounting frame 251, a tray 252 and a fourth driving unit 253; the mounting frame 251 is connected to the main frame 210, the tray 252 is slidably connected to the mounting frame 251 along the vertical direction, and the fourth driving unit 253 is connected to the mounting frame 251;

[0074] The tray 252 slides in the vertical direction relative to the mounting frame 251 under the driving action of the fourth driving unit 253 to have a position parallel to the inner end of one of the material chutes 231 , thereby receiving the material 10 released from the material chute 231 .

[0075] Therefore, through such a setting, the fourth driving unit 253 drives the tray 252 to move in the vertical direction to adjust the height of the tray 252, so that it can be adjusted to the same height as the material chute 231 in one of the pallets 220, and then, under the action of the corresponding first driving unit 235, the first limit block 232 in the corresponding material chute 231 is driven to move, so that the material 10 in the material chute 231 can be pushed into the tray 252; then, the fourth driving unit 253 drives the tray 252 to move in the vertical direction, so that the material 10 in the tray 252 can be lifted to a height that is convenient for taking out, so as to facilitate taking out the material 10.

[0076] It should be noted that, from the above content, it can be seen that before the tray 252 receives the material 10, it is necessary to drive the transmission rod 243 to move relative to the limit frame 242 through the third driving unit 244, so as to drive the movement of multiple third limit blocks 245, thereby making the multiple second limit blocks 233 be located in the second position; and after the tray 252 receives the material 10, it is necessary to drive the transmission rod 243 to move relative to the limit frame 242 through the third driving unit 244, so as to drive the movement of multiple third limit blocks 245, thereby making the multiple second limit blocks 233 be located in the first position.

[0077] In addition, it can be known from the above content that each pallet 220 in this embodiment can be connected to two material storage units 230, and the two material storage units 230 are arranged side by side; therefore, when each pallet 220 is connected to two or more material storage units 230, when the tray 252 receives the material 10, it is necessary not only to adjust the height of the tray 252, but also to drive the tray 252 to move horizontally so as to correspond to one of the material slideways 231 at the same height;

[0078] Thus, the mounting frame 251 includes a first mounting plate 254, a second mounting plate 255 and a fifth driving unit 256; the first mounting plate 254 is connected to the main frame body 210; the second mounting plate 255 is slidably connected to the first mounting plate 254 along the arrangement direction of the two material storage units 230 on the same pallet 220, the tray 252 is slidably connected to the second mounting plate 255 along the vertical direction, and the fifth driving unit 256 is connected to the second mounting plate 255; the fifth driving unit 256 is connected to the first mounting plate 254, and is used to drive the second mounting plate 255 to slide relative to the first mounting plate 254.

[0079] That is, the fifth driving unit 256 can be used to drive the second mounting plate 255 to slide relative to the first mounting plate 254, thereby driving the tray 252 connected to the second mounting plate 255 to slide along the arrangement direction of the two material storage units 230, so that the tray 252 is adjusted to a position corresponding to one of the multiple material chutes 231 arranged side by side.

[0080] For further information, please refer to Figure 1-Figure 13 In this embodiment, when the above-mentioned lifting unit 250 is set, since the lifting unit 250 and the second limit block 233 are located on the same side of the main frame 210, a space for the second limit block 233 to slide is formed between the lifting unit 250 and the main frame 210. At the same time, in order to enable the tray 252 of the lifting unit 250 to abut against the corresponding material chute 231 when receiving the material 10, so that the material 10 can smoothly move from the material chute 231 to the tray 252, the lifting unit 250 also includes a tray frame 257 and a sixth drive unit 258, the tray frame 257 is connected to the second mounting plate 255, and the sixth drive unit 258 is connected to the tray frame 257;

[0081] The tray 252 is slidably connected to the tray frame 257 along the sliding direction of the pallet 220 , and the sixth driving unit 258 is used to drive the tray 252 to move along the sliding direction of the pallet 220 so that the tray 252 has a position to abut against the inner end of one of the material chutes 231 .

[0082] Therefore, through such a setting, the tray 252 can be driven by the sixth driving unit 258 to move along the sliding direction of the support plate 220, so that the tray 252 can abut against the inner end of the material chute 231.

[0083] It should be noted that, from the foregoing content, it can be seen that the fourth driving unit 253 can drive the tray 252 to move in the vertical direction, the fifth driving unit 256 can drive the tray 252 to slide along the arrangement direction of the two material storage units 230, and the sixth driving unit 258 can drive the tray 252 to move along the sliding direction of the pallet 220. Therefore, the fourth driving unit 253, the fifth driving unit 256 and the sixth driving unit 258 can drive the tray 252 to move along the X-axis, Y-axis and Z-axis directions in space, so that the position of the tray 252 can be accurately adjusted according to the requirements of use.

[0084] In summary, please refer to Figure 1-Figure 13 Based on the above content, the present invention also provides a biological detection device, which includes a device body and the above-mentioned stacking mechanism 200; the stacking mechanism 200 is connected to the device body.

[0085] The stacking mechanism 200 may be connected to the device body or outside the device body, and is used to store the material 10 required by the biological detection device, and the material 10 may be a Tip head box.

[0086] By adopting the above-mentioned stacking mechanism 200, the biological detection device has the following advantages:

[0087] It has the function of automatically arranging the Tip header boxes;

[0088] The number of Tip header boxes can be automatically calculated, which is convenient for experimenters to understand whether the number of Tip header boxes meets the requirements of a process experiment;

[0089] It has the function of storing Tip head boxes;

[0090] Can store different specifications of Tip boxes (200 μl and 1000 μl);

[0091] It has the function of providing boxes of corresponding specifications at the designated location. The tray 252 in the lifting unit 250 has the ability to move in the X, Y, and Z axes, and has a large stroke in the Z axis direction, so it can provide boxes of corresponding specifications at the designated location.

[0092] Small size can be integrated inside the equipment, convenient for supporting the continuous automated biological experiment process in a closed environment;

[0093] The material slides in the material slideway 231 on the upper support plate 220 assembly of the box, and the sliding friction is small.

[0094] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
