[0030] In the following description, a large number of details are provided so as to enable a thorough understanding of the utility model. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the utility model, and the utility model can be implemented without one or more such details. In addition, in order to avoid confusion with the utility model, some technical features known in the art are not described in detail.

[0031] ​​According to one aspect of the present application, a sample point plate unfolding device is provided. The sample point plate unfolding device can be applied to any suitable equipment, including but not limited to a sample point device. Therefore, according to another aspect of the present application, a sample point device is provided. The sample point device can perform sample point on a sample point plate, and the sample point plate after sample point can be unfolded in the sample point plate unfolding device.

[0032] Referring to Figure 1 and Figure 2The sample spotter device can include a sample spreading tank 100 and a holder 200. The sample spreading tank 100 can be configured as a cavity 120 with an opening 110 at one end. A sample spotter 300 can be inserted into the cavity 120 through the opening 110. The sample spotter 300 can be disposed in the cavity 120 by the holder 200. Here, the sample spotter 300 is not strictly required to be completely located in the cavity 120 when the sample spotter 300 is disposed in the cavity 120. When the sample spotter 300 is disposed in the cavity 120, the sample spotter 300 can have a portion located in the cavity 120 and a portion extending out of the cavity 120. The holder 200 can be at least partially located in the cavity 120. The holder 200 can guide the sample spotter 300 to be inserted into the cavity 120. For example, the holder 200 can have a portion resting on the edge of the opening 110 and a portion extending into the cavity 120, and the portion of the holder 200 extending into the cavity 120 can guide the sample spotter 300 to be inserted into the cavity 120. Of course, the holder 200 can also have any other suitable form. The cavity 120 can be connected to a plurality of liquid inlet pipes 400 for injecting liquid into the cavity 120 in a predetermined ratio, and a liquid outlet pipe 500 for discharging liquid in the cavity 120. The plurality of liquid inlet pipes 400 can be respectively connected to external liquid supply devices, which can inject liquid into the cavity 120 through the liquid inlet pipes 400. The liquid supply devices connected to the plurality of liquid inlet pipes 400 can be different, that is, the plurality of liquid inlet pipes 400 can respectively deliver different liquid. By controlling the flow rate of liquid passing through the plurality of liquid inlet pipes 400, the plurality of liquid inlet pipes 400 can inject liquid into the cavity 120 in a predetermined ratio. Here, controlling the flow rate of liquid passing through the plurality of liquid inlet pipes 400 can be achieved by any suitable form. For example, the plurality of liquid inlet pipes 400 can have different structures, so that the plurality of liquid inlet pipes 400 can have different flow areas inside, so that the flow rate of liquid passing through the plurality of liquid inlet pipes 400 can be different, and by suitable structural design, the plurality of liquid inlet pipes 400 can inject liquid into the cavity 120 in a predetermined ratio. The plurality of liquid inlet pipes 400 can also be respectively connected to control valves, and the flow rate can be controlled by the control valves of the plurality of liquid inlet pipes 400, so that the plurality of liquid inlet pipes 400 can inject liquid into the cavity 120 in a predetermined ratio. The liquid outlet pipe 500 can be one or more. The end of the liquid outlet pipe 500 away from the sample spreading tank 100 can be connected to a waste liquid tank or directly connected to the outside. The liquid outlet pipe 500 can discharge liquid in the cavity 120 by any suitable form. For example, the liquid outlet pipe 500 can be connected to a pump, and when it is required to discharge liquid in the cavity 120, the pump can discharge liquid in the cavity 120 through the liquid outlet pipe 500.The liquid discharge pipe 500 can be connected to the bottom of the cavity 120, and the liquid discharge pipe 500 can be connected with a control valve. When the control valve controls the liquid discharge pipe 500 to be opened, the liquid in the cavity 120 can enter the liquid discharge pipe 500 and be discharged to the outside. It can also be that the liquid discharge pipe 500 discharges the liquid in the cavity 120 by using the siphon principle, which will not be repeated here.

[0033] The sample point plate development cylinder device provided by the utility model can inject multiple different liquids into the development cylinder 100 according to a predetermined proportion, so that the multiple different liquids can be mixed to form the required development liquid according to the predetermined proportion. After the sample point plate 300 is developed, the liquid discharge pipe 500 can discharge the development liquid in the development cylinder 100. During the development of the sample point plate 300, the development liquid is prepared, the development liquid is injected into the development cylinder 100, and the waste liquid after the development is discharged, all of which do not need manual operation. Therefore, the automation degree of the sample point plate development cylinder device when the sample point plate 300 is developed can be higher, and the development efficiency can be higher, so that the timeliness requirement of the sample point experiment can be met.

[0034] In an embodiment of the utility model, referring to Figure 3 、 Figure 4 and Figure 5 , the placing rack 200 can include a support part 210 arranged on the edge of the opening 110. The support part 210 can be simply arranged on the edge of the opening 110, or can be arranged on the edge of the opening 110 by clamping, threaded connection or other forms. The support part 210 can cover the opening 110, and the placing rack 200 with the support part 210 can be more stably arranged on the edge of the opening 110. The support part 210 can be formed with an insertion opening 211, and the insertion opening 211 can be communicated with the opening 110. Since the support part 210 is arranged on the opening 110, the support part 210 can be higher than the opening 110, so that the insertion opening 211 can be higher than the opening 110. When the sample point plate 300 is inserted into the cavity 120, it can first pass through the insertion opening 211 and then pass through the opening 110. By arranging the support part 210 on the edge of the opening 110, the placing rack 200 can be more stably arranged on the edge of the opening 110, so that the structure of the whole device can be more stable, and the placing rack 200 can more stably guide the sample point plate 300 to be inserted into the cavity 120.

[0035] In an embodiment of the utility model, referring to Figure 3 、 Figure 4 and Figure 5The edge of the insertion port 211 can extend into the cavity 120 from the opening 110 to form a positioning portion 220, and the bottom of the positioning portion 220 can be suspended. When the sample plate 300 extends into the cavity 120, it can at least partially abut against the positioning portion 220 to extend into the cavity 120. Therefore, the placing rack 200 can better position the sample plate 300, thereby better guiding the sample plate 300 to extend into the cavity 120. After the plurality of liquids enter the cavity 120 through the plurality of liquid inlet pipes 400 in a predetermined ratio, the developing liquid formed by mixing the liquids can be located at the bottom of the cavity 120. The suspended bottom of the positioning portion 220 can avoid adversely affecting the mixing of the liquids in the cavity 120 to form the developing liquid, and can also avoid adversely affecting the development of the sample plate 300 in the developing tank 100.

[0036] Exemplarily, the positioning portion 220 can limit the sample plate 300 to be parallel to the positioning portion 220. After the sample plate 300 is arranged in the cavity 120, it can be parallel to the positioning portion 220, for example, the sample plate 300 can abut against the positioning portion 220. Such a placing rack 200 has a simpler structure, thereby making the sample plate developing tank device have a simpler overall structure and being easier to implement.

[0037] Exemplarily, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the sample plate 300 can have a first end 310 close to the opening 110 and a second end away from the opening 110, and the positioning portion 220 can limit the sample plate 300 to gradually move away from the positioning portion 220 from the first end 310 to the second end. After the sample plate 300 is arranged in the cavity 120, the first end 310 of the sample plate 300 can be located above the second end. The positioning portion 220 can limit the sample plate 300 to gradually move away from the positioning portion 220 from the first end 310 to the second end by any suitable means, for example, an inclined limiting member can be arranged on the positioning portion 220, and the sample plate 300 can abut against the limiting member. The inclined direction of the limiting member is such that the sample plate 300 abutting against the limiting member gradually moves away from the positioning portion 220 from the first end 310 to the second end. The sample plate 300 is inclined from the first end 310 to the second end, and the direction of the support force on the liquid on the sample plate 300 is more conducive to the liquid climbing on the sample plate 300, thereby the sample plate 300 in the sample plate developing tank device can have a better development effect.

[0038] Exemplarily, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The positioning part 220 can be provided with a positioning groove 221 in the same direction as the insertion opening 211. The sample plate 300 inserted into the cavity 120 through the insertion opening 211 can extend into the positioning groove 221 and be positioned through the positioning groove 221. The positioning groove 221 can have any suitable form, and only part of the sample plate 300 can pass through the positioning groove 221. For example, in the embodiment shown in the figure, only two sides of the sample plate 300 extend into the positioning groove 221. The sample plate 300 extending into the cavity 120 can first pass through the insertion opening 211, then pass through the opening 110, and finally pass through the positioning groove 221. By designing the extension direction of the positioning groove 221, the extension direction of the sample plate 300 when passing through the positioning groove 221 can be positioned, so that the inclination direction of the sample plate 300 after extending into the cavity 120 can be positioned. Moreover, after the sample plate 300 extends into the positioning groove 221, the positioning groove 221 can fix the position of the sample plate 300, and at least the part of the sample plate 300 passing through the positioning groove 221 will maintain a fixed relative position with the positioning groove 221. By providing the positioning groove 221, the sample plate 300 arranged in the cavity 120 will be more stable, and the positioning effect of the positioning groove 221 on the sample plate 300 can make the sample plate 300 arranged in the cavity 120 incline in the desired direction.

[0039] In an embodiment of the present application, referring to Figure 2 The liquid discharge pipe 500 and the plurality of liquid inlet pipes 400 can all extend into the cavity 120 from the opening 110. When the liquid discharge pipe 500 and the plurality of liquid inlet pipes 400 all extend into the cavity 120 from the opening 110, the frame 130 or the bottom of the sample plate spreading tank 100 does not need to be provided with an opening to connect with the liquid discharge pipe 500 and the plurality of liquid inlet pipes 400, so that the liquid tightness of the overall device is better, and the liquid in the cavity 120 is less likely to leak out.

[0040] For example, referring to Figure 1 and Figure 2 The positioning part 220 can separate the sample plate 300 from the liquid discharge pipe 500, and separate the sample plate 300 from the plurality of liquid inlet pipes 400. In such a sample plate spreading tank device, the sample plate 300 can be less likely to be disturbed by the liquid discharge pipe 500 and the plurality of liquid inlet pipes 400 when being spread, so that the spreading effect of the sample plate 300 in such a sample plate spreading tank device can be better.

[0041] In an embodiment of the present application, a blowing member (not shown in the figure) for blowing air to the sample plate 300 arranged in the cavity 120 can be arranged in the cavity 120. The blowing member can blow air to the sample plate 300 arranged in the cavity 120, so that the sample plate 300 can be spread more efficiently and better.

[0042] In an embodiment of the present application, referring toFigure 6 The sample point plate unwinding device can include a plurality of unwinding groups, each unwinding group can include two unwinding cylinders 100, the two unwinding cylinders 100 in each unwinding group can be connected by a connecting piece 600, and the connecting piece 600 can fix the relative position between the two unwinding cylinders 100. Such a sample point plate unwinding device can simultaneously unwind a plurality of sample point plates 300, and the overall unwinding efficiency is higher. The two unwinding cylinders 100 in each unwinding group are connected by the connecting piece 600, and the relative positions of the two unwinding cylinders 100 do not change, and the whole can be more stable.

[0043] Exemplarily, referring to Figure 6 The two unwinding cylinders 100 in each unwinding group can be provided with a blowing piece (not shown in the figure) for blowing the sample point plate 300 located in the cavity 120, and the connecting piece 600 can be provided with a baffle 610, the baffle 610 can be located between the two unwinding cylinders 100 and can separate the two unwinding cylinders 100, and the top of the baffle 610 can be not lower than the opening 110. The baffle 610 can avoid the blowing piece provided in the unwinding cylinder 100 from interfering with the other unwinding cylinder 100 in the same unwinding group, so that the unwinding effect of the sample point plate 300 in the two unwinding cylinders 100 in each unwinding group can be better, and thus the unwinding effect of the sample point plate 300 in such a sample point plate unwinding device can be better.

[0044] In an embodiment of the present application, the sample point plate unwinding device can include a cover plate device 700, the cover plate device 700 can include a cover plate 710 and a driving piece 720, and the cover plate 710 can be away from the opening 110 or cover the opening 110 under the action of the driving piece 720. The driving piece 720 can control the cover plate 710 to cover the opening 110 when needed, for example, when the sample point plate 300 is not needed to be unwound, the cover plate 710 can cover the opening 110 under the action of the driving piece 720, avoiding the cavity 120 from being affected by external environmental pollution. When the sample point plate 300 needs to be unwound, the cover plate 710 can be away from the opening 110 under the action of the driving piece 720, so that the sample point plate 300 can extend into the cavity 120 through the opening 110.

[0045] Exemplarily, the spreading tank 100 can include a frame 130 and a bottom plate opposite to the opening 110, and the frame 130 and the bottom plate can enclose to form the cavity 120. The frame 130 can include an observation surface 131, and at least the observation surface 131 of the frame 130 is transparent. The spotting plate spreading tank device can further include an image acquisition device, which can be of any suitable form. The image acquisition device can acquire the spreading condition of the spotting plate 300 in the cavity 120 through the observation surface 131. The spreading condition of the spotting plate 300 can be observed through the image acquisition device, so that the spotting plate 300 can be adjusted in time when the spreading of the spotting plate 300 has a problem, and the spotting plate 300 can be taken out in time after the spreading of the spotting plate 300 is completed. The overall efficiency of such a spotting plate spreading tank device is higher when the spotting plate 300 is spread, and the spreading effect is better.

[0046] For the spotting equipment provided by the utility model, the spotting equipment can include a carrying device and any one of the spotting plate spreading tank devices described above, and the carrying device can be of any suitable form. For example, the carrying device can include a mechanical hand, which can grab the spotting plate 300 and drive the spotting plate 300 to move. The carrying device can insert the spotting plate 300 into the cavity 120 or can take the spotting plate 300 out of the cavity 120. In such a spotting equipment, the spotting plate 300 is inserted into the cavity 120 or taken out of the cavity 120 without manual operation; and during the spreading of the spotting plate 300, the dispensing of the spreading solution, the injection of the spreading solution into the spreading tank 100 and the discharge of the waste solution after the spreading are all without manual operation. The automation degree of such a spotting equipment when the spotting plate 300 is spread can be higher, and the spreading efficiency can be higher, which can meet the timeliness requirement of the spotting experiment.

[0047] Exemplarily, the spotting equipment can further include a transfer device, which can include a plurality of transfer grooves for temporarily storing the spotting plates 300 after the spreading is completed, and the carrying device can insert the spotting plates 300 after the spreading is completed into the transfer grooves or can take the spotting plates 300 after the spreading is completed out of the transfer grooves. When a plurality of spotting plates 300 are simultaneously spread, subsequent operations on the plurality of spotting plates 300 can not be performed simultaneously, so that the plurality of spotting plates 300 after the spreading is completed are first inserted into the transfer grooves, which can avoid the spotting plates 300 after the spreading is completed from being still spread in the spreading tank 100, so that the spotting plates 300 can be prevented from being excessively spread in the spotting plate spreading tank device. In such a spotting equipment, the spreading effect of the spotting plate 300 can be better.

[0048] Exemplarily, the transfer device can include a sensor detecting the spotting plate 300 in the plurality of transfer slots. The sensor can detect whether the spotting plate 300 exists in the plurality of transfer slots, so that the transfer device can avoid inserting the spotting plate 300 with the spreading completed into the transfer slot where the spotting plate 300 has been placed. The transfer device can also take out the required spotting plate 300 from the transfer slot according to the detection result of the sensor. The spotting device can have a higher degree of automation.
