Description

Technical Field

[0001] The utility model relates to the technical field of sodium-ion battery electrode sheet detection, and particularly relates to an electrode sheet clamping device for a sodium-ion battery. Background Art

[0002] The detection of sodium-ion battery electrode sheets refers to a series of quality control and performance evaluations of electrode sheets (usually thin sheets formed by mixing negative or positive electrode materials with conductive agents, binders, etc.) during the production process of sodium-ion batteries. The quality of the electrode sheets directly affects the performance of the batteries, including energy density, power density, cycle stability, safety, and cost, etc.

[0003] A Chinese patent with the publication number CN106826606A discloses a detection fixture and a detection device for electrode sheet burrs. The working principle of this device is as follows: The moving clamping plate and the fixed clamping plate are arranged oppositely, and the moving clamping plate can move relative to the fixed clamping plate. When it is necessary to detect the burrs of the electrode sheet, move the moving clamping plate so that the gap between the moving clamping plate and the fixed clamping plate has a suitable distance. At this time, place one or more electrode sheets in the gap between the moving clamping plate and the fixed clamping plate and place the electrode sheets closely against the bottom plate. Subsequently, move the moving clamping plate in the opposite direction until the moving clamping plate and the fixed clamping plate press and fix the electrode sheets, and then the electrode sheets on this detection fixture can be detected.

[0004] The deficiencies of the above-mentioned prior art solutions are as follows: After clamping the electrode sheet on the moving clamping plate and the fixed clamping plate, the electrode sheet often has slight vibrations under the action of some environmental factors such as circulating air flow and mechanical resonance. This slight vibration will be amplified several times under the action of the detection instrument, thus easily causing misjudgment of the detection results and affecting the accuracy of the detection results. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an electrode sheet clamping device for a sodium-ion battery, so as to solve the technical problem that in the prior art, the electrode sheet often has slight vibrations under the action of some environmental factors such as circulating air flow and mechanical resonance. This slight vibration will be amplified several times under the action of the detection instrument, thus easily causing misjudgment of the detection results and affecting the accuracy of the detection results.

[0006] The technical problem to be solved by the utility model can be realized through the following technical solutions:

[0007] An electrode sheet clamping device for a sodium-ion battery, including a bottom plate. One end of the bottom plate is fixedly connected with a baffle. A clamping plate that is slidably matched with the baffle is arranged on the bottom plate.

The driving component is arranged on the clamping plate in a cooperative manner. The burr combing component includes a glass plate that is slidably matched with the baffle. A combing strip is fixedly connected to the side of the glass plate close to the clamping plate.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0023] As Figures 1-4 shown, a pole piece clamping device for a sodium-ion battery includes a bottom plate 1. One end of the bottom plate 1 is fixedly connected with a baffle 7. A clamping plate 2 that cooperates with the baffle 7 is slidably fitted on the bottom plate 1. The clamping of the pole piece is realized through the clamping plate 2 and the baffle 7. The device further includes a driving component for driving the clamping plate 2 to approach the baffle 7 and a burr carding component for carding burrs. The driving component is arranged on the clamping plate 2 in a cooperative manner. The burr carding component includes a glass plate 11 that is slidably fitted with the baffle 7. A carding strip 12 is fixedly connected to the side of the glass plate 11 close to the clamping plate 2. The carding strip 12 can be made of foam material; during use, the pole piece is placed between the baffle 7 and the clamping plate 2, ensuring that the upper edge of the pole piece is slightly higher than the top of the clamping plate 2. The clamping plate 2 is pushed close to the baffle 7 through the driving component to realize the clamping of the pole piece. Then, the glass plate 11 and the carding strip 12 are driven to move towards the clamping plate 2. The carding strip 12 scrapes the upper edge of the pole piece, so that the burrs on the upper edge of the pole piece are all carded horizontally and extend in one direction. Then, the glass plate 11 slides onto the upper surface of the clamping plate 2, thereby squeezing and fixing the position of the burrs, which is convenient for the observation of the detection instrument.

[0024] In some specific implementation schemes, in order to facilitate the detection of the pole piece, an electric guide rail 14 is arranged at the bottom of the bottom plate 1; when the burrs on the upper edge of the pole piece are carded and fixed, the bottom plate 1 can be driven to displace to one side through the electric guide rail 14, so that the upper edge of the pole piece passes through the detection end of the detection instrument in sequence from one end to the other end, which is convenient for the detection of burrs.

[0025] In some specific embodiments, in order to realize the clamping of the pole piece by the baffle 7 and the clamping plate 2, the driving assembly includes a push rod 3 fixedly connected to the clamping plate 2. A chute 6 is formed on the bottom plate 1, a slide rail 5 is fixedly connected inside the chute 6, and a slider 4 matched with the slide rail 5 is fixedly connected to the bottom of the clamping plate 2. After the pole piece is placed, the push rod 3 can be pushed, and the push rod 3 drives the clamping plate 2 to displace along the slide rail 5, so as to realize the clamping of the pole piece by the clamping plate 2.

[0026] In some specific embodiments, in order to maintain the state of the pole piece to be inspected, multiple groups of mutually matched magnetic blocks 8 are distributed on both the baffle 7 and the clamping plate 2, and a backing plate 9 is fixedly connected to the surface of the clamping plate 2 close to the baffle 7. After the clamping plate 2 and the baffle 7 complete the clamping of the pole piece, the magnetic blocks 8 on the baffle 7 and the clamping plate 2 drive the clamping plate 2 to squeeze the baffle 7, so as to ensure the clamping effect on the pole piece and maintain the state of the pole piece to be inspected. The backing plates 9 on the clamping plate 2 and the baffle 7 are attached to both sides of the pole piece, responsible for increasing the friction force received by the pole piece and at the same time reducing the mechanical damage caused by the magnetic blocks 8 on the clamping plate 2 and the baffle 7.

[0027] In some specific embodiments, in order to realize the automatic maintenance of the glass plate 11, a cleaning sleeve 10 is fixedly connected to the baffle 7, the glass plate 11 is slidably arranged inside the cleaning sleeve 10, and a pull rod 13 is fixedly connected to the glass plate 11. After the detection is completed, the pull rod 13 is pushed, and the pull rod 13 drives the glass plate 11 to displace inside the cleaning sleeve 10, and the inner wall of the cleaning sleeve 10 scrapes the surface of the glass plate 11, so as to realize the maintenance of the surface of the glass plate 11 and ensure the accuracy of the next detection result.

[0028] In some specific embodiments, in order to realize the limit of the clamping plate 2, a limit block 15 matched with the clamping plate 2 is fixedly connected to the bottom plate 1. The clamping plate 2 displaces back and forth along the slide rail 5, and the limit block 15 can limit the clamping plate 2, so as to limit the movement range of the clamping plate 2.

[0029] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:

[0030] During use, place the pole piece between the baffle 7 and the clamping plate 2, ensuring that the upper edge of the pole piece is slightly higher than the top of the clamping plate 2. After the pole piece is placed, the push rod 3 can be pushed. The push rod 3 drives the clamping plate 2 to displace along the slide rail 5, thereby realizing the clamping of the pole piece by the clamping plate 2. After the clamping plate 2 and the baffle 7 complete the clamping of the pole piece, the magnetic blocks 8 on the baffle 7 and the clamping plate 2 will drive the clamping plate 2 to squeeze the baffle 7, thus ensuring the clamping effect on the pole piece and maintaining the pole piece in a state to be inspected. The cushion plates 9 on the clamping plate 2 and the baffle 7 are attached to both sides of the pole piece, responsible for increasing the friction force received by the pole piece and at the same time reducing the mechanical damage caused by the magnetic blocks 8 on the clamping plate 2 and the baffle 7. Then pull the pull rod 13. The pull rod 13 drives the glass plate 11 and the combing strip 12 to move towards the clamping plate 2. The combing strip 12 scrapes the upper edge of the pole piece, so that the burrs on the upper edge of the pole piece are all horizontally combed and extended in one direction. Then the glass plate 11 slides onto the upper surface of the clamping plate 2, thereby squeezing and fixing the position of the burrs, which is convenient for the observation of the detection instrument.

[0031] After the burrs on the upper edge of the pole piece are combed and fixed, the electric guide rail 14 can be used to drive the bottom plate 1 to displace to one side, so that the upper edge of the pole piece passes through the detection end of the detection instrument in sequence from one end to the other end, which is convenient for the detection of burrs. After the detection is completed, push the pull rod 13. The pull rod 13 drives the glass plate 11 to displace into the cleaning sleeve 10. The inner wall of the cleaning sleeve 10 scrapes the surface of the glass plate 11, thereby realizing the maintenance of the surface of the glass plate 11 and ensuring the accuracy of the next detection result. The clamping plate 2 displaces back and forth along the slide rail 5, and the limit block 15 can limit the clamping plate 2, thereby restricting the movement range of the clamping plate 2.

[0032] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
