[0002] In the process of in-vitro diagnosis, biological samples (such as blood, urine or tissue, etc.) are usually dropped into a microfluidic disc for testing to obtain diagnostic information. Before testing with the microfluidic disc, the testing reagent can be processed by freeze-drying to form a freeze-dried ball, and the freeze-dried ball can be implanted into the disc hole on the microfluidic disc. The testing reagent processed by freeze-drying can be stably stored at room temperature, which not only prolongs the shelf life of the testing reagent and reduces the transportation and storage costs of the testing reagent, but also allows the addition of biological samples directly to the microfluidic disc when testing is required, greatly simplifying the testing operation process.

Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0026] In the following description, a large number of details are provided in order to enable a thorough understanding of the present application. However, those skilled in the art can understand that the description below only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0027] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0028] One embodiment of the present application provides a feeding device, which can accommodate different sizes and shapes of materials. A feeding device according to an embodiment of the present application will be described in detail below with reference to the drawings.

[0029] As shown in Figure 1 and Figure 2 , the feeding device comprises a tray 1, a plurality of positioning assemblies 2 and an adjusting assembly 3. The tray 1 has a plurality of loading positions 11 for stacking materials to form a material group, and the plurality of loading positions 11 are arranged at intervals along the circumferential direction of the tray 1. The plurality of positioning assemblies 2 correspond to the plurality of loading positions 11 one by one, and the positioning assembly 2 comprises a first positioning part 21 and a second positioning part 22, which cooperate to form a storage space for storing the material group. The first positioning part 21 is fixedly arranged near the center of rotation of the tray 1, and the second positioning part 22 is movably arranged near the outer edge of the tray 1. The adjusting assembly 3 is connected to the second positioning parts 22 of the adjacent two loading positions 11. The second positioning parts 22 of the adjacent two loading positions 11 are driven to move synchronously by the adjusting assembly 3, so as to simultaneously adjust the storage spaces of the adjacent two loading positions 11 to adapt to different materials.

[0030] The material can be in the shape of a sheet, and the sheets of material are stacked in a vertical direction to form a group of materials. By stacking the materials on the tray 1, the three-dimensional space of the tray 1 can be reasonably utilized, while ensuring that a large amount of materials can be stored, and the volume of the tray 1 can be avoided.

[0031] As shown in Figure 2 The number of loading positions 11 on the tray is six, and the six loading positions 11 can be uniformly spaced along the circumferential direction of the tray 1, so as to maximize the use of the space of the tray while ensuring the balance of the whole tray, and effectively improve the rationality of the layout of the tray.

[0032] The number of the first positioning part 21 and the second positioning part 22 of the same positioning assembly 2 can be two respectively, and the two first positioning parts 21 and the two second positioning parts 22 can be enclosed to form a storage space for storing a group of materials, and an open side can be formed on the side away from the tray 1, so as to conveniently take the materials through the open side. As shown in Figure 2 The tray 1 can be spaced apart along the circumferential direction of the tray 1, and the first positioning part 21 and the second positioning part 22 can be respectively abutted with the edge of the material, so as to limit the displacement of the material in the horizontal direction.

[0033] The adjusting assembly 3 can be multiple, and the adjusting assembly 3 and the positioning assembly 2 can be spaced apart along the circumferential direction of the tray 1. The adjusting assembly 3 can be connected with the second positioning part 22 of the two adjacent loading positions 11 respectively, and drive the second positioning part 22 of the two adjacent loading positions 11 to move synchronously, so as to adjust the storage space of the two adjacent loading positions 11, so that the storage space can be compatible with materials of different shapes and sizes. It can be understood that when it is necessary to adjust two second positioning parts 22 on a loading position 11 at the same time, two adjusting assemblies 3 on both sides of the loading position 11 need to be adjusted.

[0034] The loading device of the utility model can accommodate materials of different sizes and shapes by the cooperation of the first positioning part 21 and the second positioning part 22 on the loading position 11, and the synchronous movement of the second positioning part 22 of the two adjacent loading positions 11 driven by the adjusting assembly 3, so as to adjust the storage space of the two adjacent loading positions 11 at the same time. Therefore, the volume and the occupied space of the loading device are effectively reduced, the manufacturing cost of the loading device is reduced, and the practicability of the loading device is improved.

[0035] In some embodiments, as Figure 2 and Figure 3As shown, the adjusting assembly 3 comprises a transmission member 31, two ends of the transmission member 31 are connected with the second positioning portions 22 of the adjacent charging positions 11 respectively to drive the second positioning portions 22 of the adjacent two charging positions 11 to move synchronously.

[0036] The transmission member 31 can be plate-shaped and long-strip-shaped, so that the connection with the second positioning portions 22 is facilitated, the structure of the transmission member 31 is simplified, and the processing difficulty and manufacturing cost of the transmission member 31 are reduced.

[0037] In the above embodiment, the transmission member 31 can drive the second positioning portions 22 of the adjacent two charging positions to move synchronously, so that the accuracy and synchronism of the movement of the two second positioning portions 22 are effectively ensured, the mechanical structure of the adjusting assembly 3 is simplified, the occupied space of the adjusting assembly 3 is saved, and the rationality of the structure layout of the adjusting assembly 3 is effectively ensured.

[0038] In some embodiments, as shown in Figure 2 and Figure 3 The adjusting assembly 3 further comprises a pulling member 32 arranged on the transmission member 31, and the pulling member 32 is used to drive the second positioning portions 22 of the adjacent two charging positions 11 to move towards or away from the rotation center through the transmission member 31.

[0039] The pulling member 32 can be spherical or cylindrical, and the application does not make specific limitations on this.

[0040] The pulling member 32 and the transmission member 31 can be detachably connected or integrally formed, and the detachable connection can include plug-in connection or threaded connection, etc., and the application does not make specific limitations on this.

[0041] In the above embodiment, the user can push and pull the pulling member 32, so that the transmission member 31 connected with the pulling member 32 can drive the second positioning portions 22 of the adjacent two charging positions 11 to move towards or away from the rotation center, so that the storage spaces of the adjacent two charging positions 11 can be adjusted at the same time, and the rationality of the structure layout of the adjusting assembly 3 and the convenience of the user are effectively improved.

[0042] In some embodiments, as shown in Figure 3 The transmission member 31 comprises a first part 311 and a second part 312 connected with two ends of the first part 311 respectively, the tray 1 is respectively provided with a first sliding groove 12 and a second sliding groove 13, the first part 311 is located on the upper surface of the tray 1, and the second part 312 is respectively folded to the lower surface of the tray 1 through the first sliding groove 12 and the second sliding groove 13 and connected with the second positioning portions 22 of the adjacent charging positions 11.

[0043] The second part 312 can be two, and the two second parts 312 are connected to two ends of the first part 311 respectively. The first part 311 and the second part 312 can be designed in one piece.

[0044] The first sliding groove 12 and the second sliding groove 13 can be arranged at intervals along the circumferential direction of rotation, and the length direction of the first sliding groove 12 and the second sliding groove 13 can be parallel to the radial direction of the tray 1.

[0045] The tray 1 can also be provided with a first guide groove and a second guide groove corresponding to the second positioning parts 22 on the adjacent two charging positions 11 respectively. When the two second parts 312 of the transmission member 31 slide along the first sliding groove 12 and the second sliding groove 13 respectively, the second positioning parts 22 on the adjacent two charging positions 11 can slide along the first guide groove and the second guide groove respectively, thereby improving the stability of the movement of the second positioning parts 22.

[0046] In the above embodiment, the transmission member 31 can slide along the first sliding groove 12 and the second sliding groove 13 on the tray 1, thereby driving the second positioning parts 22 of the adjacent two charging positions 11 to move towards or away from the center of rotation, effectively improving the stability of the movement of the transmission member 31. Moreover, the second part 312 can be folded to the lower surface of the tray 1 through the first sliding groove 12 and the second sliding groove 13 respectively, and connected with the second positioning parts 22 of the adjacent charging positions 11, thereby forming a relatively firm connection relationship between the transmission member 31 and the tray 1, effectively improving the firmness and reliability of the feeding device.

[0047] In some embodiments, as shown in Figure 3 The upper surface of the tray 1 is provided with a plurality of positioning holes 14, and the plurality of positioning holes 14 are arranged along the radial direction of the tray 1 between the first sliding groove 12 and the second sliding groove 13. The side of the first part 311 facing the tray 1 is provided with a positioning column matched with the positioning hole 14, and the positioning column is inserted into the positioning hole 14 to limit the displacement of the transmission member 31.

[0048] The plurality of positioning holes 14 can be arranged side by side along the radial direction of the tray 1, as shown in Figure 3 The number of positioning holes 14 in the figure is two. The pulling member 32 can be connected with the first part 311, so as to drive the positioning column on the first part 311 to be separated from one positioning hole 14 on the tray 1 by pulling the pulling member 32, and then pull the pulling member 32 to the other positioning hole 14, and then insert the positioning column on the first part 311 into the other positioning hole 14, thereby completing the adjustment of the second positioning part 22.

[0049] In the above embodiment, the transmission member 31 and the second positioning portion 22 connected with the transmission member 31 can be limited at the adjusted position through the cooperation between the positioning column and the positioning hole 14, the displacement of the second positioning portion 22 under external force is avoided, the firmness of the storage space is effectively improved, and the reliability of the feeding device is improved.

[0050] In some embodiments, as shown in Figure 4 The first positioning portion 21 and / or the second positioning portion 22 are provided with an anti-adhesion member 8, at least part of the anti-adhesion member 8 extends into the storage space, and the anti-adhesion member 8 is used to act on the material below when the adjacent materials in the material group are separated.

[0051] The first positioning portion 21 and / or the second positioning portion 22 can be configured as a hollow structure, and the anti-adhesion member 8 can include an elastic member and a rolling member. The elastic member can be arranged in the first positioning portion 21 and / or the second positioning portion 22, and the arrangement direction can be perpendicular to the length direction of the first positioning portion 21 and / or the second positioning portion 22. One end of the elastic member abuts against the inner wall of the first positioning portion 21 and / or the second positioning portion 22, and the other end of the elastic member abuts against the rolling member. At least part of the rolling member extends into the storage space. The elastic member can be a spring or the like.

[0052] The anti-adhesion member 8 can be arranged on the end of the first positioning portion 21 and / or the second positioning portion 22 away from the tray 1. When the material group moves in the vertically upward direction to the anti-adhesion member 8, the material at the highest position in the material group can abut against the anti-adhesion member 8, and the rolling member moves in the direction away from the storage space. When the material at the highest position passes through the anti-adhesion member 8, the rolling member can apply a force to the material below the material at the highest position under the action of the elastic member, so as to separate the adjacent two materials.

[0053] In the above embodiment, the anti-adhesion member 8 can effectively reduce the adhesion between the materials, ensure that each material can be independently transported, avoid errors in the transportation process due to adhesion, and avoid material loss in the transportation process due to adhesion. The feeding speed and the feeding efficiency of the feeding device are effectively improved, and the possibility of material damage in the feeding process is reduced.

[0054] In some embodiments, the feeding device further includes a rotary driving assembly (not shown in the figure) connected with the tray 1. The rotary driving assembly is used to drive the tray 1 to rotate, so as to make the material group on each loading position 11 rotate to the preset position in sequence.

[0055] The rotary driving assembly can be arranged below the tray 1 and drive the tray 1 to rotate in the clockwise direction or the counterclockwise direction. The rotary driving assembly can adjust the rotation speed and the rotation direction according to different needs to adapt to different processing operations of the materials.

[0056] The preset position can correspond to one loading position 11 on the tray 1, and the rotating driving assembly can drive the tray 1 to rotate, so that the plurality of loading positions 11 on the tray 1 are sequentially rotated to the preset positions. When the loading position 11 corresponds to the preset position, the subsequent processing operation can be performed on the material group on the loading position 11.

[0057] In the above embodiment, the rotating driving assembly can drive the tray 1 to rotate, so that the material group on each loading position 11 on the tray 1 is sequentially rotated to the preset position, thereby facilitating the subsequent processing operation on the material group. In this way, not only the material group can be accurately rotated to the preset position, but also the labor cost can be effectively saved, and the automation control level of the feeding device is improved.

[0058] In some embodiments, as shown in Figure 2 and Figure 5 The feeding device further comprises a jacking assembly 4, which is arranged below the preset position. The jacking assembly 4 jacks up the material group corresponding to the preset position, and jacks up the material at the highest position in the material group to a preset height.

[0059] The jacking assembly 4 can include a jacking piece 41 and a linear driving piece 42 for driving the jacking piece 41 to move in the vertical direction. The side wall of the jacking piece 41 can be provided with a sliding rail (not shown in the figure), and the linear driving piece 42 can be provided with a sliding block (not shown in the figure) in sliding connection with the sliding rail. The sliding rail can move in the vertical direction relative to the sliding block, so that the jacking piece 41 can move in the vertical direction, thereby jacking up the material at the highest position in the material group to the preset height.

[0060] The linear driving piece 42 can include a driving piece 421, a driving wheel 422, a transmission wheel 423 and a transmission belt 424. The driving piece 421 can be connected with the driving wheel 422 and drive the driving wheel 422 to rotate in the clockwise direction or the counterclockwise direction. The transmission belt 424 can be arranged between the driving wheel 422 and the transmission wheel 423, and the transmission belt 424 can be fixedly connected with the sliding block. In this way, through the cooperation of the driving wheel 422, the transmission wheel 423 and the transmission belt 424, the circumferential rotation of the driving wheel 422 can be converted into the linear motion of the transmission belt 424, and the jacking piece 41 can be driven to move in the vertical direction by the transmission belt 424 and the sliding block.

[0061] In the above embodiment, the jacking assembly 4 can quickly jack up the material at the preset position to the preset height, thereby reducing the time and labor intensity of manual handling, and further improving the efficiency and automation level of the feeding device.

[0062] In some embodiments, as shown in Figure 1As shown, the feeding device further comprises a sensing member 5, which is used to obtain position information of the material located at the highest position in the material group.

[0063] The sensing member 5 can be arranged close to the open side of the storage space, and when the sensing member 5 senses the position information of the material located at the highest position in the material group during the movement of the material in the storage space along the vertically upward direction driven by the jacking assembly 4, it can be indicated that the material located at the highest position has moved to the position of the preset height, and thus the jacking assembly 4 can stop jacking and use other devices to perform subsequent processing operations on the material located at the highest position.

[0064] The sensing member 5 can be a proximity sensor or an infrared sensor, and the present application does not make a specific limitation thereon, and any device capable of sensing the position information of the material can be used.

[0065] In the above embodiment, the sensing member 5 can provide accurate position information, so that the jacking assembly 4 can stop moving the material group along the vertically upward direction when the material located at the highest position in the material group moves to the position of the preset height, thereby avoiding the overturning of the material group and effectively reducing the risk of accidents, and improving the safety and reliability of the feeding device.

[0066] In some embodiments, as Figure 1 As shown, the feeding device further comprises a transfer assembly 6 and a conveying member 7 for conveying the material, and the conveying member 7 has a carrier placed thereon, and the material located at the preset height is transferred to the carrier by the transfer assembly 6.

[0067] The conveying member 7 can drive the carrier placed thereon to move, and when the conveying member 7 conveys the carrier to the transfer assembly 6, the transfer assembly 6 can take the material located at the highest position in the material group and transfer it to the carrier. The conveying member 7 can be a conveying belt, and the transfer assembly 6 can be a gripper or a suction cup, and the present application does not make a specific limitation thereon.

[0068] In the above embodiment, the cooperation of the transfer assembly 6 and the conveying member 7 can reduce the dependence on manual operation and reduce labor costs, and effectively improve the automation level and efficiency of the feeding device.

[0069] According to another aspect of the present application, a freeze-dried ball implanting device is also provided, which comprises an implanting device and the feeding device as described above, and the feeding assembly is arranged upstream of the implanting device.

[0070] The tray of the feeding device stores a plurality of materials, and the materials can be microfluidic discs, and the feeding device can be used to store the microfluidic discs and convey the microfluidic discs to the implanting device. The implanting device can implant freeze-dried balls into the disc holes of the microfluidic discs.

[0071] The freeze-drying ball planting ball equipment using the above feeding device can form a material group containing storage space through the cooperation of the first positioning part 21 and the second positioning part 22 on the loading site 11, and the adjusting assembly 3 can drive the second positioning part 22 of the adjacent two loading sites 11 to move synchronously, thereby adjusting the storage space of the adjacent two loading sites 11 at the same time, so that the feeding device can accommodate materials of different sizes and shapes, effectively reducing the volume and occupied space of the feeding device, and reducing the manufacturing cost of the feeding device, and improving the practicability of the feeding device.
