[0041] According to a first aspect of the present utility model, there is provided a powder automatic sampling device, which includes a feeding channel 60, a sampling component and a second driving member 20.

[0042] Hereinafter, the specific structures of the above components of the powder automatic sampling device according to the present embodiment will be described.

[0043] In the present embodiment, as Figure 2 and Figure 3 shown, the powder automatic sampling device is used to sample the powder in a material container 70, and the material container 70 may be a ton bag.

[0044] In the present embodiment, as Figures 1 to 3 shown, the sampling component includes a sampling member 10 and a first driving member 12. The sampling member 10 can reciprocate on the feeding channel 60. A discharging position 61 is provided on the feeding channel 60, and the discharging position 61 is located at one end in the extending direction of the feeding channel 60. When the sampling member 10 moves to the discharging position 61, discharging and dumping work is performed.

[0045] In the present embodiment, as Figures 2 to 4As shown, the material taking member 10 is arranged above the material container 70. The material taking member 10 has a sunken material holding part 11. Specifically, the side wall of the material taking member 10 is formed with an inwardly sunken groove structure, so that the powder sample can be contained in the material holding part 11. The first driving member 12 is connected to the material taking member 10 and is used to drive the material taking member 10 to rotate, so that the material holding part 11 faces or backs away from the material container 70. During the process that the material holding part 11 rotates from facing the material container 70 to backing away from the material container 70, part of the powder in the material container 70 is taken out, thus realizing automatic sampling. The first driving member 12 can be a rotary motor or a rotary cylinder, etc., as long as it can drive the material taking member 10 to rotate.

[0046] In this embodiment, as Figures 1 to 3 shown, the second driving member 20 is connected to the material taking assembly and is used to drive the material taking assembly to reciprocate on the feeding channel 60, so as to convey the material holding part 11 filled with the powder sample to the discharging position 61 to prepare for discharging the sample. Specifically, the sampling process of the powder automatic sampling device is as follows: the second driving member 20 drives the material taking member 10 to move above the material container 70, and the first driving member 12 rotates the material taking member 10 to rotate the material holding part 11 facing the material container 70 to face away from the material container 70, so that part of the powder in the material container 70 is filled into the material holding part 11. The second driving member 20 drives the material taking member 10 to move to the discharging position 61, and the first driving member 12 rotates the material taking member 10 to pour out the powder in the material holding part 11, thus realizing one-time automatic sampling. There is no need for personnel to participate in the sampling process, which improves the sampling efficiency, saves manpower, and also avoids the risk of foreign objects falling caused by humans, ensuring product quality.

[0047] It should be noted that after the powder sample is discharged at the discharging position 61, the second driving member 20 drives the material taking member 10 to retreat above the material container 70 to prepare for the next sampling.

[0048] In this embodiment, the sampling frequency can be set during the charging process of the material container 70. For example, the sampling frequency can be set according to the total weight of the material container 70. During the charging process of the material container 70, when the weight of the material container 70 reaches the first sampling requirement, the charging into the material container 70 is stopped, and the powder automatic sampling device and the material container 70 move towards each other, so that the material receiving part 11 is located above the powder. After the material receiving part 11 rotates, the powder on the upper layer in the current material container 70 can be sampled. After the first sampling is completed, continue to charge the material container 70 until the weight of the material container 70 reaches the next sampling requirement, and then move the material receiving part 11 above the powder again to sample the powder newly loaded into the material container 70, so as to realize the segmented sampling of the powder in the material container 70, and further ensure that the detection data of the sample can accurately reflect the overall state of the material contained in the material container 70. The number of samplings and / or the time interval can be set according to actual detection requirements. It should be noted that the movement of the powder automatic sampling device and the material container 70 towards each other can be realized by driving devices such as motors, cylinders or manipulators.

[0049] Specifically, in a preferred embodiment, the first driving member 12 drives the material taking member 10 to rotate 180° each time, so that the material taking member 10 realizes the action of scooping out the powder from the material container 70 during the rotation process and transports the powder along the feeding channel 60 to the discharging position 61 under the action of the second driving member 20. After the second driving member 20 transports the material receiving part 11 to the discharging position 61, the first driving member 12 drives the material taking member 10 to rotate again to set the material receiving part 11 downward, so that all the powder in the material receiving part 11 is poured out.

[0050] Further, in this embodiment, as Figures 2 to 4 shown, the material taking member 10 is formed into a strip structure. The material taking member 10 can be a rod-shaped structure such as a cylindrical or prismatic shape. The second driving member 20 is connected to one end of the material taking member 10 in the length direction, and the material receiving part 11 is arranged at the other end of the material taking member 10 in the length direction. In this way, there is a certain distance between the first driving member 12 and the powder, which ensures the normal operation of the first driving member 12 and avoids contamination.

[0051] In a preferred embodiment, as Figure 1 shown, a plurality of second driving members 20 are provided. The plurality of second driving members 20 are distributed on both sides of the material taking member 10. In this way, the plurality of second driving members 20 can jointly drive the material taking assembly to move, improve the bearing capacity of the second driving member 20, ensure the smooth movement of the material taking assembly, and thus ensure the smooth transportation of the powder sample. In an alternative embodiment, two second driving members 20 are provided, and the two second driving members 20 are respectively arranged on both sides in the radial direction of the material taking member 10.

[0052] In addition, in this embodiment, as Figures 1 to 3 shown, the powder automatic sampling device further includes a support member 30. The support member 30 is formed into a tubular structure. Part of the feeding channel 60 is arranged inside the support member 30. A material taking port 31 is formed on the side wall of the support member 30 facing the material container 70. In this way, while the support member 30 provides a supporting force, it also ensures that the material taking member 10 is communicated with the material container 70. Preferably, the material taking member 10 and the support member 30 are coaxially arranged to prevent the inner wall of the support member 30 from being scratched by the material taking member 10 during the transportation of materials, so as to avoid generating foreign matters.

[0053] In a preferred embodiment, the powder automatic sampling device further includes an inflatable seal. The inflatable seal is connected to the support member 30. The inflatable seal is an airbag which has a cavity inside. By filling gas into the cavity, the inflatable seal expands to close the material taking port 31, thereby improving the sealing performance of the feeding channel 60, preventing the powder sample from being exposed to the air, and ensuring the accuracy of the sampling and detection results.

[0054] Furthermore, in this embodiment, as Figure 1 shown, the powder automatic sampling device further includes a first mounting seat 41 and a second mounting seat 42 to play a role in supporting and fixing. Specifically, the first mounting seat 41 is connected to the first driving member 12, and the second mounting seat 42 is connected to the support member 30 and the second driving member 20. Both the first mounting seat 41 and the second mounting seat 42 can be formed into plate-like structures with mounting holes. The first mounting seat 41 and the second mounting seat 42 are preferably made of metal materials, such as aluminum alloy 6061 material, so as to ensure the structural strength of the first mounting seat 41 and the second mounting seat 42.

[0055] Even further, in this embodiment, as Figure 1 shown, the second driving member 20 includes a housing 21 and a driving end 22. The driving end 22 is formed into a rod-like structure. One end of the driving end 22 in the length direction is slidably connected to the housing 21, and the other end is connected to the first mounting seat 41. The housing 21 is mounted on the second mounting seat 42. The driving end 22 can slide relative to the housing 21. In this way, during the sliding process, the first mounting seat 41 moves in the direction of approaching or moving away from the second mounting seat 42, so as to drive the material taking assembly to reciprocate on the feeding channel 60.

[0056] In this embodiment, the second driving member 20 can be a linear cylinder or a linear motor. However, the structure of the second driving member 20 is not limited to this, and it can also be a linkage mechanism, etc., as long as it can drive the material taking assembly to reciprocate.

[0057] In addition, in this embodiment, as Figures 1 to 3As shown, the powder automatic sampling device further includes a discharging member 50. The discharging member 50 is formed into a cylindrical structure surrounding the discharging position 61. A discharging port is provided at the bottom of the discharging member 50. The first driving member 12 rotates the material taking member 10 to pour the powder in the material containing part 11 out from the discharging port. Preferably, the discharging port is formed into a reduced opening structure, so that the bottom of the discharging member 50 is formed into a funnel-shaped structure to ensure accurate falling of the powder during pouring.

[0058] Further, in this embodiment, the powder automatic sampling device further includes a sample containing member. The sample containing member is arranged at the discharging port. The powder poured out from the material containing part 11 enters the sample containing member through the discharging member 50 to ensure complete storage of the sample and avoid affecting the accuracy of the detection result due to contact with air. In this embodiment, the sample containing member can be a sealed bag. A sealing strip is arranged at the opening position of the sealed bag. After the powder sample enters the sample containing member, the sampling personnel remove the sealed bag from the discharging port and seal it, and then replace it with a new sample containing member to prepare for the next sampling.

[0059] In a preferred embodiment, the material taking member 10 is a non-metallic member, for example, made of nylon material. In this way, reaction with the powder or the material container 70 during the material taking process is avoided, the purity and quality of the powder are ensured, contamination is avoided, and the detection accuracy is improved. Further, the supporting member 30 is also a non-metallic member to avoid reaction between the supporting member 30 and the powder or the material container 70, further ensuring the purity and quality of the powder and improving the detection accuracy.

[0060] According to the powder automatic sampling device of the present utility model, the second driving member drives the material taking member to move above the material container, and the second driving member rotates the material taking member to rotate the material containing part facing the material container to face away from the material container, so that a part of the powder in the material container is filled into the material containing part. The second driving member drives the material taking member to move to the discharging position, and the first driving member rotates the material taking member to pour out the powder in the material containing part. In this way, one automatic sampling is realized, without the need for personnel to participate in the sampling process, the sampling efficiency is improved, labor is saved, and the risk of foreign objects falling caused by humans is also avoided, ensuring the product quality.

[0061] According to a battery production device provided by the present utility model, which includes the above-mentioned powder automatic sampling device, the production efficiency and production reliability of the battery production device can be effectively improved, and to a certain extent, the production cost of the battery production device can also be reduced, having good application value.

[0062] Finally, it should be noted that the above-described embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the technical field of the present application can still modify the technical solutions described in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application.
