Description

Technical Field

[0001] The present disclosure relates to the technical field of battery materials, and in particular to a stirring paddle detection mechanism and a reaction device. Background Art

[0002] In the process of battery material production, positive electrode slurry and negative electrode slurry need to be configured in the cylinder assembly. The slurry is a mixture of positive electrode main material and conductive agent dispersed in solvent NMP, which is a suspension; when preparing negative electrode slurry, the slurry is a mixture of negative electrode main material graphite, thickener and binder dispersed in solvent water, which is also a suspension. Therefore, the positive electrode slurry and negative electrode slurry in the cylinder need to be stirred separately.

[0003] During the batching process, in order to better mix the slurry, a stirring paddle with a larger diameter is used for stirring, so that the stirring paddle is as close to the inner diameter of the cylinder assembly as possible. However, during the process of feeding and discharging and the raising and lowering of the stirring paddle, the stirring paddle will deviate to a certain extent, resulting in the stirring paddle not being at the center of the cylinder assembly. If the stirring paddle deviates seriously, it will directly cause the cylinder to be scraped. If the stirring paddle deviates less, since the stirring paddle is closer to one side of the inner wall of the cylinder assembly, a slight scraping of the cylinder will also occur when the paddle material is stirred. Scraping the cylinder will cause metal debris from the cylinder assembly and the stirring paddle to contaminate the slurry, causing a certain impact on production.

[0004] For example, the lifting type lithium battery cell slurry stirring device disclosed in the comparative document CN201921486145.1 includes a base, a moving assembly, a connecting rod assembly and a stirring assembly; the base is in the shape of a horizontal plate, the cross section of the base is H-shaped, there are recessed chutes on the top surfaces of both sides of the base, a horizontal plate is horizontally arranged in the middle of the base, and the moving assembly is installed on the horizontal plate; stirring barrels are arranged at both ends of the chutes on both sides; a frame is fixedly connected to the middle of the base, and the connecting rod assembly is arranged in the middle of the top surface of the top plate of the frame, and the connecting rod assembly includes a rotating motor, a first connecting rod, and two second connecting rods; the stirring assembly includes a mounting plate, a lifting motor, a lifting gear, and a lifting plate, and a fixed plate is horizontally fixedly connected to the bottom end of the lifting plate, and the stirring motor on the fixed plate drives the stirring rod to rotate. This scheme can realize the stirring of the cell slurry, and can be moved and stirred up and down during use, which is convenient for adjustment. However, this solution cannot determine whether the stirring component is offset. When the stirring component is offset, it is easy to scratch the stirring barrel and produce debris, causing the slurry in the stirring barrel to be contaminated, thereby affecting the production of the slurry.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figures 1 to 4 As shown, the stirring paddle detection mechanism 10 of an embodiment of the present disclosure includes a cylinder assembly 100, a stirring structure 200 and a detection structure 300. The cylinder assembly 100 is provided with a reaction chamber 101, and the reaction chamber 101 is used to load raw materials for reaction. The top of the cylinder assembly 100 is also provided with a through hole 102 connected to the reaction chamber 101. The stirring structure 200 includes a driving assembly 210, a stirring shaft 220 and a stirring paddle 230. The driving assembly 210 is connected to the top of the cylinder assembly 100. The driving assembly 210 is used to control the rotation and movement of the stirring shaft 220. The driving assembly 210 can also adjust the stirring shaft 220 for lifting and lowering. The stirring shaft 220 is penetrated by the through hole 102. The two ends of the stirring shaft 220 are respectively connected to the driving assembly 210 and the stirring paddle 230. The stirring paddle 230 is located in the reaction chamber 101.

[0033] Furthermore, the detection structure 300 includes a deformation component 310 and an image detection component 320. There are multiple deformation components 310. Multiple deformation components 310 are connected to the inner wall of the cylinder assembly 100. Multiple deformation components 310 are arranged at circumferential intervals along the center of the stirring paddle 230. The image detection component 320 is installed at the bottom of the reaction chamber 101. The image detection component 320 is used to detect the deformation of each deformation component 310, and the image detection component 320 obtains the position of the stirring paddle 230.

[0034] In this embodiment, a plurality of deformation components 310 are first arranged at intervals on the inner wall of the cylinder assembly 100, and the driving component 210 then moves the stirring shaft 220 and the stirring paddle 230 up and down to the same horizontal plane as the deformation component 310, and the image detection component 320 installed at the bottom of the reaction chamber 101 is turned on, and the image detection component 320 detects and records the initial data of the deformation component 310; the driving component 210 then controls the stirring shaft 220 and the stirring paddle 230 to rotate to perform slow stirring of the empty cylinder. When the stirring paddle 230 is too close to the inner wall of the cylinder assembly 100, the deformation component 310 contacts the stirring paddle 230 and is deformed. The image detection component 320 detects and records the deformation data of the deformation component 310 to obtain the position of the stirring paddle 230, the adjustment direction of the stirring paddle 230 and the adjustment distance, and then the stirring shaft 220 and the stirring paddle 230 are moved by the driving component 210 for adjustment.

[0035] The above-mentioned stirring paddle detection mechanism 10 has multiple deformation components 310 arranged at circumferential intervals along the center of the stirring paddle 230. The deformation components 310 are deformed when in contact with the stirring paddle 230. The position information of the stirring paddle 230 is obtained by detecting the changes of the deformation components 310 through the image detection component 320, thereby accurately controlling the stirring paddle 230 to move to a safe position, avoiding the position deviation of the stirring paddle 230 in the reaction chamber 101, preventing the stirring paddle 230 from scraping the cylinder to generate debris, avoiding the contamination of slurry production by debris, protecting the stirring paddle 230 and reducing the work of production and maintenance.

[0036] like Figure 5 As shown, in one embodiment, each deformation component 310 includes a magnetic connection member 311, a metal wire 312 and a deformation member 313, each magnetic connection member 311 is connected to the inner wall of the cylinder assembly 100, each magnetic connection member 311 is arranged at intervals along the circumference of the center of the stirring paddle 230, one end of each metal wire 312 is fixed to the corresponding magnetic connection member 311, and the other end of each metal wire 312 is connected to the corresponding deformation member 313. In this embodiment, the cylinder assembly 100 does not need to be processed by magnetic attraction, and the deformation component 310 can be quickly installed on the inner wall of the cylinder assembly 100 for detection. After the detection, the magnetically attracted deformation component 310 can be quickly disassembled, which speeds up the detection and adjustment speed of the stirring paddle 230 position, thereby speeding up the slurry production speed.

[0037] like Figure 5 As shown, in one embodiment, there are multiple metal wires 312, multiple metal wires 312 are connected to the center of a magnetic connection member 311, and the other ends of multiple metal wires 312 are respectively connected to corresponding deformable members 313. In this embodiment, the deformable member 313 is easier to deform, and multiple metal wires 312 are connected to corresponding deformable members 313 to increase the connection strength between the deformable member 313 and the magnetic connection member 311, thereby reducing the deformation member 313 from falling off.

[0038] like Figure 1 and Figure 6 As shown, in one embodiment, the image detection component 320 includes a magnetic fixing part 321 and an image capturing part 322. The magnetic fixing part 321 is connected to the bottom of the image capturing part 322. The magnetic fixing part 321 is adsorbed on the inner wall at the bottom of the cylinder assembly 100. The image capturing part 322 is used to detect the deformation of the deformation component 310. In this embodiment, the image capturing part 322 needs to be disassembled after the detection is completed, and raw materials are added to the reaction container to produce the slurry. The magnetic fixing part 321 is connected to the inner wall at the bottom of the cylinder assembly 100 by magnetic attraction, so that the image capturing part 322 can be quickly disassembled and assembled on the cylinder assembly 100 through the magnetic fixing part 321, thereby speeding up the production speed of the slurry.

[0039] like Figure 6 As shown, in one embodiment, there are multiple magnetic fixing members 321, and the multiple magnetic fixing members 321 are spaced apart at the bottom of the image capturing member 322, and the multiple magnetic fixing members 321 are all adsorbed on the inner wall at the bottom of the cylinder assembly 100. In this embodiment, the adsorption capacity between the multiple magnetic fixing members 321 and the cylinder assembly 100 is increased, the connection strength between the image capturing member 322 and the cylinder assembly 100 is increased, and the image capturing member 322 is prevented from moving, so that the detection result of the image capturing member 322 is more accurate.

[0040] like Figure 1 As shown, in one embodiment, the image detection component 320 further includes a laser positioning member 321, which is connected to the top of the image capture member 322, and is used to emit positioning light. In this embodiment, the laser positioning member 321 emits a red laser beam along the inner wall of the cylinder assembly 100, and the inner wall of the cylinder assembly 100 presents a plurality of positioning red dots, and the deformation component 310 can be sequentially installed on the positioning red dots, so that the deformation component 310 is accurately installed, so that the image detection component 320 can detect the position of the stirring paddle 230 more accurately, and adjust the position of the stirring paddle 230 more accurately.

[0041] like Figure 5As shown, in one embodiment, the deformable member 313 is a spherical structure. In this embodiment, the spherical deformable member 313 is easy to manufacture and convenient for the image detection component 320 to detect the deformation of the deformable member 313, thereby speeding up the detection speed of the image detection component 320 to detect the deformable member 313.

[0042] like Figures 1 to 3 As shown, in one embodiment, the diameter of the deformable member 313 is the difference between the maximum inner diameter of the reaction chamber 101 and the maximum inner diameter of the stirring paddle 230 . In the present embodiment, when the diameter of the deformable member 313 is smaller than the difference between the maximum inner diameter of the reaction chamber 101 and the maximum inner diameter of the stirring paddle 230, the deformable member 313 is not easily deformed, the stirring paddle 230 is offset, the stirring paddle 230 is too close to the inner wall of the cylinder assembly 100, and the stirring paddle 230 is prone to scraping the cylinder; when the diameter of the deformable member 313 is larger than the difference between the maximum inner diameter of the reaction chamber 101 and the maximum inner diameter of the stirring paddle 230, the stirring paddle 230 is not offset and the deformable member 313 is deformed, the image detection component 320 detects the deformable member 313 inaccurately, and cannot determine whether the stirring paddle 230 is offset; when the diameter of the deformable member 313 is equal to the difference between the maximum inner diameter of the reaction chamber 101 and the maximum inner diameter of the stirring paddle 230, the deformation of the deformable member 313 occurs when the stirring paddle 230 is offset, and the image detection component 320 accurately detects the deformation of the deformable member 313, thereby accurately adjusting the position of the stirring paddle 230.

[0043] like Figure 1 As shown, in one embodiment, the cylinder assembly 100 includes a tank cover 110 and a tank body 120, the tank body 120 is provided with a through hole 102, and the tank cover 110 is arranged to cover the entrance of the tank body 120. In this embodiment, the reaction container 101 of the tank body 120 is opened by lifting the tank cover 110, so as to install the deformation assembly 310 and the image detection assembly 320. When working, materials can be put into the entrance of the tank body 120, and then the entrance of the tank body 120 is tightly covered by the tank cover 110, so as to prevent the materials from splashing.

[0044] The present application also provides a reaction device including the stirring paddle detection mechanism 10 in any of the above embodiments. In this embodiment, the image detection component 320 detects the change of the deformation component 310, and then adjusts the position of the stirring paddle 230, thereby avoiding the stirring paddle 230 from scraping the cylinder to generate debris, thereby reducing the pollution to the slurry production.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] The above-mentioned stirring paddle detection mechanism 10 and reaction device, multiple deformation components 310 are arranged at circumferential intervals along the center of the stirring paddle 230, the deformation component 310 contacts the stirring paddle 230 to generate deformation, and the image detection component 320 detects the change of the deformation component 310 to obtain the position information of the stirring paddle 230, thereby accurately controlling the stirring paddle 230 to move to a safe position, avoiding the position deviation of the stirring paddle 230 in the reaction chamber 101, preventing the stirring paddle 230 from scraping the cylinder to generate debris, avoiding the pollution of slurry production by debris, protecting the stirring paddle 230 and reducing the work of production and maintenance.

[0047] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
