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.

[0025] In one embodiment of the present application, a filling device is provided, which can avoid the occurrence of air bubbles in the to-be-filled member during the filling process. In the following, a filling device according to an embodiment of the present application will be described in detail with reference to the drawings.

[0026] As Figure 1As shown, the filling device comprises a mounting frame 1 and a filling assembly 2, the filling assembly 2 is obliquely arranged on the mounting frame 1, and a filling position for placing a to-be-filled member is arranged below the filling assembly 2. The filling assembly 2 has a penetrating portion 21 capable of penetrating into the to-be-filled member placed on the filling position, and a liquid outlet 211 is formed on the penetrating portion 21 and capable of abutting against the inner side wall of the to-be-filled member.

[0027] The mounting frame 1 can be arranged along a vertical direction, and the filling assembly 2 can be arranged on the mounting frame 1 and form a certain oblique angle with the mounting frame 1, so that the filling assembly 2 can form a certain oblique angle with the to-be-filled member placed along the vertical direction.

[0028] The to-be-filled member can have an open side for filling the filling liquid, and the penetrating portion 21 of the filling assembly 2 can penetrate into the to-be-filled member through the open side and make the liquid outlet 211 on the penetrating portion 21 abut against the side wall of the to-be-filled member. The to-be-filled member can be a test tube, a beaker or the like, which is not limited in the present application.

[0029] The filling position can be located on the moving path of the penetrating portion 21 of the filling assembly 2, so that when the to-be-filled member is placed on the filling position, the penetrating portion 21 of the filling assembly 2 can accurately penetrate into the to-be-filled member.

[0030] One end of the filling assembly 2 close to the to-be-filled member can be the liquid outlet 211, and the other end of the filling assembly 2 away from the to-be-filled member can be a liquid inlet, and the filling liquid can enter the liquid inlet of the filling needle 23 and be discharged from the liquid outlet 211 of the filling needle 23.

[0031] The filling device of the present application can obliquely arrange the filling assembly 2 on the mounting frame 1, when the to-be-filled member is placed on the filling position, the liquid outlet 211 of the filling assembly 2 can abut against the inner side wall of the to-be-filled member, so that the filling liquid filled through the filling assembly 2 can flow into the to-be-filled member along the inner side wall of the to-be-filled member, avoiding the splashing of the liquid in the to-be-filled member during the filling process, effectively reducing the waste of the filling liquid, and improving the operation environment and the safety of the operator. When the filling device is applied to biological detection, the situation of generating bubbles in the to-be-filled member during the filling process can be avoided, effectively improving the accuracy of the biological detection result.

[0032] In some embodiments, as shown in Figures 1 to 3 The filling assembly 2 comprises a mounting plate 22 and a filling needle 23, the mounting plate 22 is obliquely arranged on the mounting frame 1, the filling needle 23 is arranged on the mounting plate 22, and the penetrating portion 21 is formed on the end of the filling needle 23 away from the mounting plate 22.

[0033] The number of filling needles 23 can be multiple, and the multiple filling needles 23 are arranged at intervals along the length direction of the mounting plate 22 to improve the filling efficiency of the filling assembly 2.

[0034] The mounting plate 22 can be long strip-shaped or square-shaped, and preferably long strip-shaped. The long strip-shaped mounting plate 22 can uniformly and evenly arrange the multiple filling needles 23 arranged thereon. The shape of the mounting plate 22 is not limited in the application.

[0035] In the above embodiment, the mounting plate 22 can be arranged on the mounting rack 1 at an angle, so that the filling needle 23 forms a certain angle with the to-be-filled member. The filling needle 23 can be arranged on the mounting plate 22, so that the mounting plate 22 can provide support to the filling needle 23, thereby improving the stability of the filling needle 23 during movement and effectively improving the reliability of the filling assembly 2.

[0036] In some embodiments, as shown in Figures 1 to 3 The filling assembly 2 further comprises a positioning assembly 24 arranged on the mounting plate 22. The positioning assembly 24 is used to limit the relative position of the filling needle 23 and the mounting plate 22.

[0037] In the above embodiment, the positioning assembly 24 is used to limit the relative position of the filling needle 23 and the mounting plate 22, so as to avoid the position of the filling needle 23 from deviating, thereby causing the liquid outlet 211 of the filling needle 23 to fail to accurately abut against the inner side wall of the to-be-filled member. This effectively improves the reliability and practicality of the filling assembly 2.

[0038] In some embodiments, as shown in Figures 1 to 3 The positioning assembly 24 comprises a first positioning member 241 and a second positioning member 242. The first positioning member 241 is arranged on the upper wall of the mounting plate 22, and the filling needle 23 is arranged on the first positioning member 241 and the mounting plate 22 in sequence. The second positioning member 242 is arranged on the side wall of the mounting plate 22 and abuts against the filling needle 23.

[0039] The filling needle 23 can be arranged on the first positioning member 241, and the first positioning member 241 is arranged on the upper wall of the mounting plate 22, so as to avoid the filling needle 23 from falling off the mounting plate 22, thereby limiting the displacement of the filling needle 23 relative to the mounting plate 22 in the vertical direction.

[0040] The second positioning member 242 can have an elastic abutting portion on one end close to the filling needle 23. The side wall of the mounting plate 22 can have an insertion hole.

The elastic abutting portion can apply a force to the filling needle 23 to firmly abut the filling needle 23 on the mounting plate 22, thereby limiting the displacement of the filling needle 23 relative to the mounting plate 22 in the horizontal direction.

[0041] When the filling needle 23 needs to be replaced, the second positioning member 242 can be pulled out of the insertion hole of the mounting plate 22, so that the replacement of the filling needle 23 is quickly completed, effectively saving the replacement time.

[0042] When the filling needle 23 is multiple, each filling needle 23 can have a first positioning member 241 and a second positioning member 242 corresponding thereto, so that each filling needle 23 can be independently replaced.

[0043] In the above embodiment, through the cooperation of the first positioning member 241 and the second positioning member 242, the filling needle 23 can be firmly fixed to the mounting plate 22, avoiding the situation that the filling needle 23 falls off, and the replacement of the filling needle 23 can be quickly completed by using the second positioning member 242, effectively improving the reliability and practicality of the filling assembly 2 and the convenience of the replacement of the filling needle 23.

[0044] In some embodiments, a plurality of mounting holes with different hole diameters are formed on the mounting plate 22, and the filling needle 23 is arranged in the mounting hole matched therewith.

[0045] The filling needle 23 can have different diameters according to actual use needs, and the mounting plate 22 can have mounting holes matched with filling needles 23 of different diameters, and filling needles 23 of different diameters can be arranged in the mounting holes matched therewith.

[0046] In the above embodiment, a plurality of mounting holes with different hole diameters can be formed on the mounting plate 22, so that filling needles 23 of different diameters can be arranged on the mounting plate 22, and the filling assembly 2 can simultaneously meet different filling needs, effectively improving the practicality and universality of the filling assembly 2.

[0047] In some embodiments, as shown in Figures 1 to 3 The filling device further comprises a first driving member 3, the filling assembly 2 is connected with the mounting frame 1 through the first driving member 3, and the first driving member 3 is used to drive the filling assembly 2 to reciprocate in a first direction.

[0048] The first direction can be represented as the direction of the Y axis in the Cartesian coordinate system, that is, the vertical direction. The first driving member 3 can drive the filling assembly 2 to reciprocate in the vertical direction, so as to ensure that the filling assembly 2 can move into the to-be-filled member.

[0049] The first driving member 3 can be a cylinder or other devices capable of driving the filling assembly 2 to move, and the type of the first driving member 3 is not limited in the application.

[0050] In the above embodiment, the first driving member 3 can be used to drive the filling assembly 2 to reciprocate along the first direction, so that the insertion part 21 of the filling assembly 2 can be inserted into the to-be-filled member when filling is needed, and withdrawn from the to-be-filled member after filling is completed, thereby effectively improving the flexibility and practicability of the filling assembly 2.

[0051] In some embodiments, as shown in Figures 1 to 3 the filling device further comprises a second driving member 4 connected with the first driving member 3, and a driving end of the second driving member 4 is connected with the filling assembly 2. The second driving member 4 is used to drive the filling assembly 2 to reciprocate along the second direction.

The second driving member 4 can drive the filling assembly 2 to reciprocate in the horizontal direction, so as to ensure that the filling assembly 2 can be moved to the position of the to-be-filled member.

[0053] The second driving member 4 can be a pneumatic cylinder or other devices capable of driving the filling assembly 2 to move, and the type of the second driving member 4 is not limited in the present application.

[0054] In the above embodiment, the second driving member 4 can be used to drive the filling assembly 2 to reciprocate along the second direction, so that the filling assembly 2 can be flexibly moved to the position of the to-be-filled member, thereby achieving a larger filling range and further improving the flexibility and practicability of the filling assembly 2.

[0055] In some embodiments, as shown in Figure 2 the filling device further comprises a third driving member 5 and a liquid receiving member 6 connected with the third driving member 5. After the filling assembly 2 completes filling, the third driving member 5 drives the liquid receiving member 6 to move below the filling assembly 2.

[0056] The above filling completion can be understood as when the liquid outlet 211 of the filling assembly 2 is separated from the inner side wall of the to-be-filled member after the filling assembly 2 adds the filling liquid into the to-be-filled member.

[0057] Before filling by using the filling assembly 2, the third driving member 5 can drive the liquid receiving member 6 to move away from the filling assembly 2, so as to avoid the movement path of the filling assembly 2 when moving into the to-be-filled member. After filling is completed, the third driving member 5 can drive the liquid receiving member 6 to move close to the filling assembly 2, so that the residual filling liquid on the filling assembly 2 can drop onto the liquid receiving member 6.

[0058] The liquid receiving area of the liquid receiving member 6 can be greater than the projection area of the filling assembly 2, so that the liquid receiving member 6 can completely cover the liquid outlet 211 of the filling assembly 2, thereby avoiding the situation that the residual filling liquid on the filling assembly 2 drops to the area outside the liquid receiving member 6.

[0059] The liquid receiving member 6 can be in the shape of a groove, and a drain opening for draining residual filling liquid can be arranged on the bottom wall of the liquid receiving member 6, and the filling liquid dropped onto the liquid receiving member 6 can be drained through the drain opening.

[0060] The third driving member 5 can be a cylinder or other device capable of driving the liquid receiving member 6 to move, and the type of the third driving member 5 is not limited in the application.

[0061] In the above embodiment, the third driving member 5 can drive the corresponding movement of the liquid receiving member 6 according to the use needs of the filling assembly 2, thereby avoiding the pollution of the filling device and the environment where the filling device is located due to the dripping of residual filling liquid on the filling assembly 2, effectively improving the practicality of the filling device and the convenience of use of the user.

[0062] In some embodiments, as shown in Figure 2 and Figure 3 The filling device further comprises a liquid filling pipe, a first fixing member 7 and a second fixing member 8, the first fixing member 7 and the second fixing member 8 are sequentially arranged above the filling needle 23 in the vertical direction, and the liquid filling pipe is sequentially arranged in the first fixing member 7 and the second fixing member 8 and connected with the liquid inlet of the filling needle 23.

[0063] The liquid filling pipe can be a flexible hose, which can avoid affecting the movement of the filling assembly 2. Each filling needle 23 can have a corresponding liquid filling pipe.

[0064] The first fixing member 7 and the second fixing member 8 can be respectively installed on the mounting rack 1, the installation height of the second fixing member 8 can be higher than the arrangement height of the filling needle 23, and the installation height of the first fixing member 7 can be higher than the installation height of the second fixing member 8, so that the filling liquid in the liquid filling pipe can flow into the liquid inlet of the filling needle 23 in the vertical direction after sequentially passing through the first fixing member 7 and the second fixing member 8.

[0065] In the above embodiment, the filling liquid in the liquid filling pipe can flow into the liquid inlet of the filling needle 23 after sequentially passing through the first fixing member 7 and the second fixing member 8, thereby avoiding affecting the filling amount and filling speed of the filling liquid due to the bending of the liquid filling pipe, and further improving the practicality of the filling device and the user experience.
