Detailed Implementation

[0022] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0023] This embodiment provides an automatic filling device for sodium-nickel battery anode powder, such as... Figure 1As shown, the device includes a feeding mechanism 10, a guiding feeding mechanism 20, and a housing support mechanism 30. The feeding mechanism 10 includes a support frame 11 and a storage hopper 12 and a discharge assembly 13 mounted thereon. The feeding mechanism 10 stores and provides anode powder 40. It is understood that the storage hopper 12 should have a filling port and a discharge port 121. In this embodiment, the filling port is preferably located at the top of the storage hopper 12, and the discharge port 121 is located at the bottom of the storage hopper 12, which has a conical structure. The discharge assembly 13 controls the discharge amount and whether discharge occurs. It is understood that the discharge assembly 13 should be located at the discharge port 121 of the storage hopper 12. The guiding feeding mechanism 20 can be located below the feeding mechanism 10 to receive the anode powder 40. In this embodiment, under normal conditions, the guiding feeding mechanism 20 can be located directly below the feeding mechanism 10 or to one side below the feeding mechanism 10, and the two only connect when needed. In this embodiment, the latter is preferred. This facilitates the handling of nickel-sodium battery casings. The guiding feeding mechanism 20 includes a track frame 24 and a receiving funnel 21. The track frame 24 is vertically arranged, and the receiving funnel 21 is mounted on the track frame 24 via a lifting unit and can move relative to the track frame 24. That is, the lifting unit can drive the receiving funnel 21 to move up and down relative to the track frame 24, thereby adjusting the position of the receiving funnel 21 to align it with the discharge port 136 of the feeding mechanism 10 and the nickel-sodium battery casing placed on the casing support structure. This receiving funnel is used to feed the nickel-sodium battery casing. The anode powder 40 in mechanism 10 is transferred and filled into the sodium-nickel battery housing 32; the housing support mechanism 30 is located directly below the receiving funnel 21, and includes a support base 31 for supporting the sodium-nickel battery housing 32. It is understood that the housing support mechanism 30 should be provided with a columnar receiving groove adapted to the structure of the sodium-nickel battery housing 32 to achieve stable support for the sodium-nickel battery housing 32, thereby ensuring that the receiving funnel and the sodium-nickel battery housing 32 are accurately connected; in this embodiment, the support base 31 is welded from metal materials.

[0024] In this embodiment, preferably, during filling, the discharge port 136 of the feeding mechanism 10, the receiving funnel 21 and the sodium-nickel battery casing are coaxial and tightly connected, and the anode powder 40 received in the receiving funnel 21 will be directly filled into the sodium-nickel battery casing.

[0025] Specifically, this embodiment designs an automatic anode powder 40 filling device consisting of a feeding mechanism 10, a guiding feeding mechanism 20, and a housing support mechanism 30. The feeding mechanism 10 is mainly used to store the anode powder 40, the housing support mechanism 30 is used to support and limit the sodium-nickel battery housing 32, and the guiding feeding mechanism 20 is mainly used to transfer the anode powder 40 in the feeding mechanism 10 and fill it into the sodium-nickel battery housing 32. That is, this embodiment of the device can realize the automatic filling of anode powder 40 without frequent manual intervention, reducing human error, improving the filling efficiency of anode powder 40, solving the existing shortcomings, and has certain practical value and economic benefits.

[0026] As a preferred embodiment, the guide feeding mechanism 20 is located on one side of the feeding mechanism 10, and the two are only connected when needed. This facilitates the placement and removal of the nickel-sodium battery casing on the support base 31. Otherwise, it would be impossible to achieve coaxial and tight connection between the discharge port 136 of the feeding mechanism 10, the receiving funnel 21, and the nickel-sodium battery casing. Of course, when a conduit 26 is connected to the bottom of the receiving funnel 21, such as Figure 5 Alternatively, the guide feeding mechanism 20 can be directly connected to the feeding mechanism 10.

[0027] In this embodiment, the guide feeding mechanism 20 is preferably located on one side of the feeding mechanism 10, and a horizontal slide rail 14 is provided at the bottom of the feeding mechanism 10. The horizontal slide rail 14 includes a support rail 144 and a drive unit. The drive unit can drive the feeding mechanism 10 to slide relative to the support rail 144 to achieve docking or separation with the guide feeding mechanism 20. Specifically, in a normal scenario, the initial point of the feeding mechanism 10 is located at one end of the horizontal slide rail 14. When needed, the drive unit is activated, and the feeding mechanism 10 is moved relative to the support rail 144 to the other end. At this time, the feeding mechanism 10 is exactly above the receiving funnel 21. Then, the height of the receiving funnel 21 is adjusted by the lifting unit to tightly dock with the discharge port 121 of the storage hopper 12 for powder receiving. After filling is completed, the drive unit is activated again to reset the feeding mechanism 10 to the initial point.

[0028] In this embodiment, the drive unit includes a drive motor A141 and a lead screw A142, which are located on the support rail 144. Figure 4 As shown, the bottom of the feeding mechanism 10 is connected to the lead screw A142 via a slider 143. The slider 143 can move relative to the lead screw A142, thereby driving the feeding mechanism 10 to move. In this embodiment, the bottom of the feeding mechanism 10 is provided with a slide rail, and a guide rail is provided on the support rail 144. The feeding mechanism 10 and the support rail 144 are stably connected by the sliding fit of the slide rail and the guide rail, which improves the stability of the operation of the feeding mechanism 10.

[0029] As a preferred embodiment, the discharge assembly 13 includes a horizontal extension plate 131 and a discharge gate 132, such as Figure 2 As shown, a horizontal extension plate 131 is fixed to a support frame 11, and a discharge port 136 is provided on the horizontal extension plate 131. The horizontal extension plate 131 serves as a support mechanism to support a discharge gate 132. The discharge gate 132 is fixed to the horizontal extension plate 131 and serves as a switch assembly to control the opening and closing degree of the discharge port 121 of the storage hopper 12. The discharge gate 132 is provided with a discharge slot 133, which is connected to the discharge port 121 on the storage hopper 12. The discharge port 136 on the horizontal extension plate 131 is coaxial and sealed together. It is understood that adjacent ports can be directly connected or connected through a flexible hose. In this embodiment, it is preferred to connect through a flexible hose to improve the sealing performance of the connection. At the same time, a telescopic push rod 134 and a sealing plate 135 are provided on the discharge gate 132. The telescopic push rod 134 can push the sealing plate 135 to move relative to the discharge gate 132 to close or open the discharge slot 133, thereby realizing the control of the discharge port 121 of the storage hopper 12.

[0030] like Figure 3 The diagram shown is an exploded view of the discharge assembly 13 provided in this embodiment. As can be seen from the diagram, the discharge gate 132 is a composite plate consisting of a layer plate 1321 and a cover plate 1322. The cover plate 1322 is disposed at the upper end of the layer plate 1321. The layer plate 1321 has a sandwich structure with a cavity inside. In this embodiment, the cavity is preferably a rectangular cavity corresponding to the diameter of the discharge slot hole 133. The sealing plate 135 is disposed within the cavity of the layer plate 1321 and has a reciprocating movement space within the cavity of the layer plate 1321. The track groove 1323 has a telescopic push rod 134 located at one end of the shelf 1321 and connected to the sealing plate 135. In use, the telescopic push rod 134 is activated, which drives the sealing plate 135 to move within the track groove 1323. When the telescopic push rod 134 extends, it drives the sealing plate 135 to move into the discharge slot 133 to close the discharge slot 133. When the telescopic push rod 134 retracts, it drives the sealing plate 135 to move away from the discharge slot 133 to open the discharge slot 133.

[0031] In this embodiment, a pad 137 fixed by a screw can be provided on one side between the feeding gate 132 and the horizontal extension plate 131. The pad 137 adjusts the state of the feeding gate 132 relative to the horizontal plane, making it non-horizontally placed. Its main function is to convert the circular discharge port formed by the overlap of the feeding slot hole 133 and the discharge port 136 into a crescent-shaped discharge port, thereby adjusting the feeding speed and flow rate and ensuring the continuity and stability of the anode powder 40 feeding. In this embodiment, the thickness of the pad 137 is related to the state of the anode powder 40. The thickness and installation position of the pad 137 can be continuously adjusted during the machine adjustment process to determine the ideal position. In this embodiment, the maximum thickness of the pad 137 is about 1 cm, so it does not affect the normal use of the telescopic push rod 134 and the sealing plate 135.

[0032] As a preferred embodiment, the feeding mechanism 10 is provided with a vibrator 15, which is preferably installed at the bottom of the horizontal extension plate 131. The vibrator 15 can provide vibration force to the feeding mechanism 10 to prevent the anode powder 40 from accumulating in the storage hopper 12.

[0033] In this embodiment, a material level sensor 122 is provided on the storage hopper 12 near the discharge port 121. The material level sensor 122 can monitor the amount of anode powder 40 in the storage hopper 12 in real time.

[0034] As a preferred embodiment, the guide feeding mechanism 20 includes a vertical track frame 24 and a receiving funnel 21. The receiving funnel 21 is mounted on the track frame 24 via a lifting unit. The lifting unit includes a drive motor B22 and a lead screw B23. The receiving funnel 21 is connected to the lead screw B23 via a sliding sleeve 25. The sliding sleeve 25 can move up and down relative to the lead screw B23 to adjust the position of the receiving funnel 21.

[0035] As a preferred embodiment, the housing support mechanism 30 includes a weighing sensor 33, which is disposed at the bottom of the support base 31. The weighing sensor 33 can collect and control the amount of anode powder 40 filled into the sodium-nickel battery housing 32, thereby improving the accuracy of anode powder 40 filling. At the same time, the collected anode powder 40 filling data is saved, which can be used as a basis for judging whether the feeding status is qualified or unqualified, and can also be used as a basis for the influencing factors of anode powder 40 filling amount in the cell performance analysis.

[0036] The principle used in this embodiment includes: Sufficient anode powder 40 is added to the storage hopper 12 of the feeding mechanism 10 in advance, and the discharge gate 132 is kept closed. At the same time, a suitable pad 137 is selected to adjust the discharge flow rate of the discharge slot 133. When filling is required, first place the sodium-nickel battery casing on the support base 31, then start the drive motor B22 to rotate the lead screw B23, which in turn moves the receiving funnel 21 relative to the lead screw B23 through the sliding sleeve 25 until it aligns with the sodium-nickel battery casing placed on the support base 31. Then start the drive motor A141 to rotate the lead screw A142, which, under the action of the slider 143, moves the feeding mechanism 10 as a whole until it aligns with the receiving funnel 21. After alignment, start the telescopic push rod 134 to move the sealing plate 135 to open the discharge slot 133. At this time, the anode powder 40 in the storage hopper 12 will fall into the receiving funnel 21 and be filled through the receiving funnel 21. During the filling process, if necessary, the vibrator 15 is activated to vibrate the feeding mechanism 10 inside the sodium-nickel battery casing. At the same time, the remaining amount of anode powder 40 in the storage hopper 12 is monitored by the material level sensor 122, and the filling amount of anode powder 40 in the sodium-nickel battery casing is collected by the weighing sensor 33 and transmitted to the remote host computer for storage. After filling is completed, the drive motor A141 is first activated to drive the lead screw A142 to rotate in the opposite direction to move the feeding mechanism 10 as a whole to the side of the guide unloading mechanism 20 to complete the reset. Then, the drive motor B22 is activated to drive the lead screw B23 to rotate in the opposite direction to move the receiving funnel 21 to the designated position. Finally, the sodium-nickel battery casing can be removed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
