Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery electrode coating technology, and in particular to a sodium-ion battery electrode coating device. Background Technology
[0002] Sodium-ion batteries have stood out among new energy storage devices due to their advantages such as high safety, strong thermal stability and excellent electrochemical performance, and are expected to partially replace lithium-ion batteries. In the preparation process of sodium-ion battery electrodes, the battery electrode coating process is required, followed by drying and pressing to prepare qualified positive / negative electrode sheets.
[0003] In related technologies, patent CN221166806U discloses an electrode coating device for sodium-ion battery production. The device includes a table, a telescopic rod slidably connected to the inner wall of the table, and a telescopic serration fixedly connected to one end of the telescopic rod. A helical gear is 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 placement cavity allows for better positioning of the suction device. When the rotating column reaches the electrode placement platform, the suction pump starts working, sucking up the electrode through the suction tube and suction head. The electrode is placed in the placement cavity to solve the problem that during the pressing process of the battery electrode, the battery is subjected to a large pressure, which may cause deviation after pressing, thus affecting the pressing effect of the battery electrode. However, the device achieves the rotation operation of the suction tube through a complex transmission, which is complex in structure and high in cost. Furthermore, due to the size limitations of the equipment table and telescopic saw teeth, the rotation adjustment range of the suction tube is limited, and only one set of electrode can be transferred at a time, resulting in low efficiency. The electrode placement table lacks a clamping and fixing device, which can easily cause the electrode to shift or slip, affecting subsequent processing. Therefore, we propose a sodium-ion battery electrode coating equipment.
[0004] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0005] The purpose of this invention is to provide a sodium-ion battery electrode coating device to solve the problems mentioned in the background art. The device achieves the rotation operation of the suction tube through complex transmission, which is complex in structure and high in cost. Furthermore, due to the size limitations of the equipment table and telescopic saw teeth, the range of adjustment for the rotation of the suction tube is limited, and only one set of electrodes can be transferred at a time, resulting in low efficiency. The electrode placement table lacks a clamping and fixing device, which can easily lead to electrode displacement or slippage, affecting subsequent processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sodium-ion battery electrode coating device includes a main body, a transfer component fixedly disposed at the center of the main body, a support component symmetrically disposed on both sides of the transfer component, and a suction component detachably and symmetrically disposed at the upper end of the transfer component.
[0008] The transfer assembly includes a rotating disk, which is disposed at the upper end of the main body of the equipment. The lower end of the rotating disk is connected to the output end of a second motor in a second motor box via a second rotating shaft. The second motor box is fixedly disposed in the internal mounting cavity of the main body of the equipment. Two sets of suction assemblies are detachably and symmetrically fixed at the upper end of the rotating disk.
[0009] The bearing assembly includes a rotatable bearing disk. The lower end of the bearing disk is connected to the output end of a first motor in a first motor box via a first rotating shaft. The first motor box is detachably and fixedly installed in an installation cavity inside the main body of the equipment. Four sets of placement cavities are symmetrically and fixedly installed on the upper end of the bearing disk.
[0010] The supporting components are symmetrically arranged on both sides of the transfer component, and there are two sets of supporting components.
[0011] In some embodiments, the suction assembly includes a second telescopic rod detachably fixed to the upper end of the support plate. A fixing rod is bolted to the upper end of the second telescopic rod.

[0012] In some embodiments, a suction head is installed at the lower end of the suction tube, a fixing rod passes through the upper end of the suction tube, and a suction pump is installed on the suction tube.
[0013] In some embodiments, electrode placement assemblies are symmetrically installed on the other two sides of the rotating disk. Each electrode placement assembly includes a vacuum suction cup disposed above the main body of the device. A vacuum tube is integrally formed at the lower end of the vacuum suction cup. An exhaust pipe is integrally formed at one end of the vacuum tube. One end of the exhaust pipe passes through the main body of the device and extends to the outside of the main body. A vacuum pump is installed on the exhaust pipe. A fixing sleeve is installed on the side of the vacuum tube at the upper end of the main body of the device. The fixing sleeve is detachably connected to the upper end of the main body of the device via a connecting rod.
[0014] In some embodiments, a locking disc is sleeved on the side of the first rotating shaft at the lower end of the bearing disk. The lower end of the locking disc is connected and fixed to the upper end face of the first motor box through a first telescopic rod.

The combination of an electric telescopic rod and a vacuum suction cup enables automated adjustment of electrode sheet height and stable adsorption, reducing manual intervention. A locking mechanism (locking disc and locking rod) physically locks the load-bearing disc, preventing electrode sheet displacement caused by slight rotation and ensuring placement accuracy. A limiting groove at the lower end of the rotating disk, in conjunction with a limiting rod, limits the rotation angle, preventing over-rotation and improving the positioning accuracy of the transfer components. Both the load-bearing and suction components are detachable for easy replacement or maintenance. An inspection port on the side of the equipment simplifies maintenance of internal components such as motors and vacuum pumps. The electrode placement component uses a vacuum suction cup to fix the electrode sheets, with adsorption / release controlled by a solenoid valve to prevent electrode slippage or positional displacement, ensuring the stability of the plating process.

[0029] The support assembly 2 includes a rotatable support plate 201. The lower end of the support plate 201 is connected to the output end of the first motor in the first motor box 203 via a first rotating shaft 204. The first motor box 203 is detachably and fixedly installed in the mounting cavity inside the main body 1 of the equipment.

[0031] The rotating disk 401 rotates under the drive of the second motor. In conjunction with the suction component 5 set at the upper end of the rotating disk 401, it realizes the suction and transfer of battery electrode sheets. Furthermore, multiple sets of suction component 5, bearing component 2 and electrode sheet placement component 3 are provided, which greatly improves the efficiency of electrode sheet suction and transfer, and thus improves the efficiency of subsequent electrode sheet processing.
[0032] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, the suction assembly 5 includes a second telescopic rod 501 detachably fixed to the upper end of the support plate 201. A fixing rod 502 is bolted to the upper end of the second telescopic rod 501. The fixing rod 502 is horizontally arranged.

The upper end of the suction tube 503 passes through the fixing rod 502. A suction pump 505 is installed on the suction tube 503. Both the first telescopic rod 208 and the second telescopic rod 501 are electric telescopic rods. The height of the suction tube 503 and the suction head 504 are adjusted by the second telescopic rod 501 to realize the automatic suction and transfer of the battery electrode.

The fixing sleeve 306 is detachably connected to the upper end of the main body 1 by a connecting rod 305. The electrode is fixed by the vacuum suction cup 301 to prevent the electrode from shifting or slipping. Solenoid valves are installed on both the suction tube 503 and the vacuum tube 302. After the suction head 504 picks up and fixes the electrode, the solenoid valve on the vacuum tube 302 can be opened to release the vacuum suction cup 301 from fixing the electrode, making it easier for the suction tube 503 to pick up and transfer the electrode.
[0034] In specific implementation of the embodiments of this utility model, such as Figure 1 , 4 As shown, a locking disc 206 is fitted onto the side of the first rotating shaft 204 at the lower end of the bearing plate 201.

At the same time, the limiting groove 404 and the limiting rod 405 at the lower end of the rotating plate 401 ensure that the rotating plate 401 does not rotate excessively, thereby improving the transfer accuracy of the rotating plate 401 and the upper suction component 5.

After adsorption is completed, the second telescopic rod 501 rises, and the rotating disk 401 rotates to the target position (placement cavity) under the drive of the second motor.
[0040] Locking and limiting: During the operation of the rotating disk 401, the bearing disk 201 is fixed in position by inserting the locking rod 207 into the locking hole 205 to avoid rotational error;

[0042] Electrode plating and cycling:
[0043] Electrode release: After being transferred to the target position, the solenoid valve on the suction tube 503 opens, releasing the electrode to the plating station (placement chamber);
