Description

Technical Field

[0001] This utility model application relates to the field of sodium-ion battery technology, specifically a separator coating device for sodium-ion battery production. Background Technology

[0002] Sodium-ion batteries are rechargeable batteries that operate on a similar principle to lithium-ion batteries, but use sodium ions as charge carriers. The positive and negative electrodes are made of materials that allow sodium ions to intercalate and deintercalate, and the electrolyte is an organic solution containing sodium salts or a solid electrolyte. During charging and discharging, Na⁺ migrates back and forth between the positive and negative electrodes, converting electrical energy into chemical energy. Sodium-ion batteries have potential applications in large-scale energy storage and low-speed electric vehicles due to the abundance of sodium resources, low cost, and high safety. However, their energy density and cycle life are slightly lower than lithium-ion batteries, making them a current research focus. Their technological development aims to supplement, rather than completely replace, lithium batteries, promoting the diversification of clean energy storage.

[0003] Traditional diaphragm coating methods typically involve workers placing the diaphragm on a coating device and then pushing it with a moving block on the activation device to apply the coating. To ensure uniform coating, the moving block often moves slowly. When workers need to process multiple diaphragms, this coating method greatly reduces coating efficiency. Utility Model Content

[0004] To address the problem that the slow movement speed of the moving blocks often significantly reduces the coating efficiency of this coating method, this invention provides a membrane coating device for sodium-ion battery production to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A membrane coating apparatus for sodium-ion battery production includes a coating apparatus body. A movable block body is disposed on the top surface of the coating apparatus body. A first coating frame is fixed on the top surface of the coating apparatus body. A second coating frame is fixed on the top surface of the first coating frame. Another movable block body is slidably disposed on the top surfaces of the first coating frame and the second coating frame, respectively. A connecting block is fixed on both sides of each movable block body. A connecting hole is symmetrically opened on each connecting block. A connecting rod is disposed between every two adjacent connecting blocks. The connecting rod is slidably disposed inside the connecting hole on one side of the two connecting blocks. A connecting nut is threaded to the top and bottom surfaces of each connecting rod. The three movable block bodies are connected by the connecting rod.

[0006] Furthermore, the top surfaces of the coating device body, the first coating rack, and the second coating rack are all provided with connection holes, and each of the moving block bodies is slidably disposed inside the connection hole.

[0007] Furthermore, a fixed frame is fixed inside the lower part of the first coating frame, and a sliding rod is provided above the fixed frame. The sliding rod is slidably connected to another movable block body on the top surface of the first coating frame.

[0008] Furthermore, a rodless cylinder is fixed inside the lower part of the second coating rack, and the output end of the rodless cylinder extends to the center of the bottom end of the third moving block body on the top surface of the second coating rack.

[0009] Furthermore, the bottom end of the first coating rack is fixed with a first fixing foot, and the top surface of the coating device body is provided with a slot that mates with the first fixing foot. The first fixing foot is fixedly connected to the coating device body by a first fixing bolt.

[0010] Furthermore, the bottom end of the second coating rack is fixed with a second fixing foot, and the top surface of the first coating rack is provided with a second slot that mates with the second fixing foot. The second fixing foot is fixedly connected to the first coating rack by a second fixing bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a first coating frame is set on the top surface of the coating device body, and the first coating frame is fixedly connected to the coating device body by a first fixing bolt. At the same time, a second coating frame is set on the top surface of the first coating frame, and the second coating frame is fixed to the first coating frame by a second fixing bolt. Simultaneously, a moving block body is slidably set on the top surface of the coating device body, the first coating frame, and the second coating frame, and the three moving block bodies are connected by a connecting rod. When the coating device body moves the moving block bodies on the top surface of the coating device body, the three moving block bodies move simultaneously through the connecting rod, and the three diaphragms are coated simultaneously. This solves the problem that the moving speed of the moving blocks is often slow, which greatly reduces the coating efficiency of this coating method.

[0012] 2. In this utility model, by setting a sliding rod inside the first coating frame, the main body of the moving block above the first coating frame is slidably connected to the sliding rod, which improves the stability of the main body of the moving block above the first coating frame. At the same time, a rodless cylinder is set inside the second coating frame, so that the output end of the rodless cylinder moves simultaneously with the movement of the coating device body, thereby assisting the coating device body to drive the three second coating frames to move, avoiding the problem that the three moving block bodies cannot move at the same time or that the column gets stuck.

Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A membrane coating device for sodium-ion battery production includes a coating device body 1, a movable block body 4 on the top surface of the coating device body 1, a first coating frame 2 fixed on the top surface of the coating device body 1, a second coating frame 3 fixed on the top surface of the first coating frame 2, and another movable block body 4 slidably disposed on the top surfaces of the first coating frame 2 and the second coating frame 3, respectively, with connecting blocks 5 fixed on both sides of each movable block body 4, and connecting holes 6 symmetrically opened on each connecting block 5, with a connecting rod 7 disposed between every two adjacent connecting blocks 5, the connecting rod 7 slidably disposed inside the connecting hole 6 on one side of the two connecting blocks 5, and connecting nuts 8 threadedly connected to the top and bottom surfaces of each connecting rod 7, the three movable block bodies 4 being connected by the connecting rods 7, so that the coating device body 1, the first coating frame 2 and the second coating frame 3 can be coated simultaneously.

[0018] Specifically, the top surfaces of the coating device body 1, the first coating rack 2, and the second coating rack 3 are all provided with connection holes 6, and each moving block body 4 is slidably disposed inside the connection hole 6 to improve the sliding stability of the moving block body 4.

[0019] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixed frame 11 is fixed inside the lower part of the first coating frame 2, and a sliding rod 12 is provided above the fixed frame 11. The sliding rod 12 is slidably connected to another movable block body 4 on the top surface of the first coating frame 2. A first fixed foot 14 is fixed at the bottom end of the first coating frame 2. A slot is opened on the top surface of the coating device body 1 to cooperate with the first fixed foot 14. The first fixed foot 14 is fixedly connected to the coating device body 1 by the first fixed bolt 9, thereby improving the fixing strength of the first coating frame 2.

[0020] Specifically, a rodless cylinder 13 is fixed inside the lower part of the second coating frame 3. The output end of the rodless cylinder 13 extends to the center of the bottom end of the third moving block body 4 on the top surface of the second coating frame 3. A second fixed foot 15 is fixed at the bottom end of the second coating frame 3. A second slot that mates with the second fixed foot 15 is opened on the top surface of the first coating frame 2. The second fixed foot 15 is fixedly connected to the first coating frame 2 by a second fixed bolt 10, thereby improving the fixing strength of the second coating frame 3.

[0021] Working principle: Based on the required number of diaphragms to be coated, the first fixing foot 14 is placed in the slot on the top surface of the coating device body 1, allowing the first coating frame 2 to be placed on the top surface of the coating device body 1. Simultaneously, the four first fixing feet 14 are fixed to the coating device body 1 using the first fixing bolts 9. Then, the vertical positions of the two moving block bodies 4 are aligned, and the connecting rod 7 is passed through the connecting hole 6 on the same side of the two connecting blocks 5. The two ends of the connecting rod 7 are then fixed using the connecting nut 8, thus connecting the two moving block bodies 4 together via the connecting rod 7. Next, the second fixing foot 15 is aligned with another slot on the top surface of the first coating frame 2, and the second coating frame 3 is fixed to the first coating frame 2 using the second fixing bolt 10. Simultaneously, through the above method, another connecting rod 7 connects the first coating frame 2 and the second coating frame 3... The moving block body 4 is fixed together, and two connecting rods 7 are respectively set inside the two connecting holes 6 of the connecting block 5 to avoid mutual interference between the two connecting rods 7. When the operator places the diaphragm on the top surface of the coating device body 1, the first coating rack 2 and the second coating rack 3, the moving block body 4 above the coating device body 1 is moved by starting the coating device body 1. At the same time, the three moving block bodies 4 are connected together by the two connecting rods 7, so that the three moving block bodies 4 move at the same time. At this time, the rodless cylinder 13 is activated, so that the rodless cylinder 13 pushes the connecting block 5 above the second coating rack 3 to move. At the same time, the moving speed of the rodless cylinder 13 is the same as the moving speed of the moving block body 4 on the top surface of the coating device body 1. Meanwhile, the moving block body 4 on the top surface of the first coating rack 2 is slidably connected to the slide rod 12, so that the movement of the three moving block bodies 4 is more stable.
