Description

Technical Field

[0001] This utility model relates to the field of sodium battery production technology, specifically to an electrode coating device for sodium battery production. Background Technology

[0002] In the prior art, a search revealed that Chinese patent (application number: 202322522233.5) discloses an electrode coating equipment for sodium-ion battery production. The equipment includes a table, a telescopic rod slidably connected to the inner wall of the table, a telescopic serration fixedly connected to one end of the telescopic rod, and a helical gear rotatably connected to the inner wall of the table. Through a transmission device, the telescopic serration on the telescopic rod meshes with the helical gear, causing the helical gear to rotate. The movable groove and fixed rod are limiting devices for the rotating column. The placement cavity allows for better limiting of the suction device. When the rotating column rotates to the electrode placement table, the suction pump starts working, sucking up the electrode through the suction pipe and suction head, and placing the electrode in the placement cavity. This solves the problem that during the pressing process of battery electrodes, the battery is subjected to high pressure, causing deviations after pressing, which affects the pressing effect of the battery electrodes.

[0003] However, when using the above-mentioned patent, the electrode is prone to tilting during the manual placement of the electrode on the electrode placement table, and may not be directly under the suction head. This may cause the suction head to fail to effectively pick up the electrode. In addition, manually placing the electrode one by one on the electrode placement table is very time-consuming and affects efficiency. Therefore, improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an electrode coating device for sodium battery production, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electrode coating device for sodium battery production includes a worktable and an inverted U-shaped support. Several legs are fixed to the bottom of the worktable. The lower ends of two legs of the support are fixed to the top of the worktable. A motor is vertically installed at the center of the bottom of the top plate of the support. A connecting plate is fixed to the lower end of the motor's output device. One end of the connecting plate extends along one of the legs of the support. A suction mechanism is installed at the free end of the connecting plate. A support plate is also fixed to the top of the worktable. The support plate is located directly below the suction head of the suction mechanism. A placement mechanism is also provided on the top of the worktable. The placement mechanism is symmetrically arranged with the support plate.

[0007] Specifically, in this utility model, the placement mechanism includes a placement hole opened on the top of the workbench, and a guide structure is also provided at the bottom of the workbench. The upper end of the guide structure is connected to the placement hole, and the guide structure includes a placement cylinder with an upper opening connected to the placement hole and a lower closed end.

[0008] Specifically, in this utility model, a carrier is slidably installed inside the placement tube. The carrier includes a carrier plate slidably installed inside the placement tube. A spring is vertically installed inside the placement tube and is fixed between the bottom of the carrier plate and the placement tube.

[0009] In order to guide the carrier plate and prevent the electrode from tilting, two symmetrically arranged sliding grooves are opened on the inner wall of the placement cylinder, and two symmetrically arranged sliders are fixed on the carrier plate, with the sliders slidably installed in the sliding grooves.

[0010] Compared with the prior art, this utility model has the following advantages: the placement cylinder in the placement mechanism can guide the electrode sheets, prevent the electrode sheets from being placed crookedly by hand, and multiple electrode sheets can be placed in the placement cylinder at one time, which saves more time than placing them one by one by hand.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-3As shown, this utility model provides an electrode coating device for sodium battery production, including a workbench 1 and an inverted U-shaped support 2. Several legs 3 are fixed to the bottom of the workbench 1. The lower ends of two legs of the support 2 are fixed to the top of the workbench 1. A motor 4 is vertically installed at the center of the bottom of the top plate of the support 2. A connecting plate 11 is fixed to the lower end of the output of the motor 4. One end of the connecting plate 11 extends along one of the legs of the support 2. A suction mechanism 5 is installed at the free end of the connecting plate 11. A carrying plate 6 is also fixed to the top of the workbench 1, located directly below the suction head of the suction mechanism 5. All of the above structures are existing technologies. The motor 4 is connected to an external power source and drives the suction mechanism 5 to move back and forth above the support plate 6 and the placement mechanism via the connecting plate 1111. The mechanism stops at the support plate 6 via an external controller. This allows the electrode M in the placement mechanism to be placed onto the sodium-ion battery in the support plate 6. The suction mechanism 5 is also in the prior art. The principle of the entire method of moving the electrode M can also use the patent in the prior art (application number: 202322522233.5), which will not be repeated in this utility model. The top of the workbench 1 is also provided with a placement mechanism, which is symmetrically arranged with the support plate 6.

[0019] like Figure 3-4 As shown, in this utility model, the placement mechanism includes a placement hole on the top of the workbench 1, and a guide structure is provided at the bottom of the workbench 1. The upper end of the guide structure is connected to the placement hole. The guide structure includes a placement cylinder 7, with the upper end of the placement cylinder 7 open and connected to the placement hole, and the lower end closed.

[0020] like Figure 4 As shown, in this utility model, a carrier is slidably installed inside the placement cylinder 7. The carrier includes a carrier plate 8 slidably installed inside the placement cylinder 7. A spring 9 is vertically installed inside the placement cylinder 7 and is fixed between the bottom of the carrier plate 8 and the placement cylinder 7.

[0021] like Figure 5 As shown, in order to guide the bearing plate 8 and prevent the electrode plate M from tilting, two symmetrically arranged sliding grooves 7-1 are opened on the inner wall of the placement cylinder 7. Two symmetrically arranged sliders 10 are fixed on the bearing plate 8, and the sliders 10 are slidably installed in the sliding grooves 7-1.

[0022] The working principle of this utility model is described in detail below: The sodium-ion battery is placed in the placement tray, and multiple electrode plates M are placed in the placement cylinder 7. The weight of the multiple electrode plates M compresses the spring 9 downwards, thus placing the electrode plates M. This allows multiple electrode plates M to be placed at once, which is more time-saving than the traditional manual placement. Moreover, compared with manual placement, the placement cylinder 7 can play a good guiding role and prevent the electrode plates M from tilting. Then, after the electrode plates M are removed one by one, the weight of the remaining electrode plates M in the placement cylinder 7 decreases. Through the elastic force of the spring 9, the electrode plates M are lifted up and brought close to the suction head of the suction mechanism 5. This can save the power of the suction mechanism 5 and does not require increasing the suction force of the suction head. Finally, the cooperation between the slider 10 and the slide groove 7-1 prevents the carrier plate 8 from tilting when moving in the placement cylinder 7.

[0023] Finally, the contribution of this utility model is that the placement cylinder 7 in the placement mechanism can guide the electrode M, preventing the electrode M from being placed crookedly by hand. Moreover, multiple electrode M can be placed in the placement cylinder 7 at one time, which saves more time compared to placing them one by one manually.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
