[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0038] In the field of battery manufacturing technology, accurate and stable transfer of separators for coating and lamination has a crucial impact on the quality of the resulting battery cells.

[0039] Reference Figure 1As shown, an embodiment of the present application provides a diaphragm transmission mechanism, which includes a material roll 1, a tension control component 2, a diaphragm transmission correction component 3, a diaphragm buffer component 4, a tension isolation component 5 and a coating component 6, wherein: after the diaphragm 11 is sent out from the material roll 1, it passes through the tension control component 2, the diaphragm transmission correction component 3, the diaphragm buffer component 4, the tension isolation component 5 and the coating component 6 in sequence; the tension control component 2 is used to detect and adjust the tension of the diaphragm 11 in transportation; the diaphragm transmission correction component 3 is used to detect and adjust the conveying path of the diaphragm 11 in transportation; the diaphragm buffer component 4 is used to cache a diaphragm 11 of a predetermined length, and convey the cached diaphragm 11 to the tension isolation component 5; the tension isolation component 5 is used to isolate the tension of the diaphragm 11 and convey the diaphragm 11 after the tension is isolated to the coating component 6; the coating component 6 is used to convey the diaphragm 11 after the tension is isolated to a stacking platform (not shown) for laying.

[0040] During specific implementation, the diaphragm transmission mechanism includes a material roll 1, a tension control component 2, a diaphragm transmission correction component 3, a diaphragm buffer component 4, a tension isolation component 5 and a coating component 6 which can be fixedly installed on the installation wall 7, and the stacking platform is arranged below the coating component 6, and the stacking platform can usually move back and forth relative to the coating component 6, and when the stacking platform is located on both sides of the coating component 6, the battery pole piece is transported to the diaphragm 11 and placed thereon, and during the reciprocating movement, the diaphragm 11 is bent and coated on the battery pole piece.

[0041] The above introduces the overall structure of the diaphragm transmission mechanism. Figure 2 , Figure 3 Combined with Figure 1 As shown, the diaphragm transmission correction component 3 is further described.

[0042] The embodiment of the present application provides a membrane transmission deviation correction component 3, which includes a driving component 32, a rotating component 33, a rotating shaft 34 and a substrate 31, wherein: one end of the substrate 31 can be fixedly arranged on the installation wall 7, and the extension of one end to the other end is perpendicular to the installation wall 7, and the driving component 32 is installed on the substrate 31; the rotating component 33 is rotatably connected with the substrate 31 through the rotating shaft 34, and the rotating component 33 includes a first roller 331, the first roller 331 is used to support the membrane 11 and guide the conveying path of the membrane 11, the rotating shaft 34 is perpendicular to the first roller 331, and the rotating component 33 is driven by the driving component 32 to rotate around the rotating shaft 34. The rotating component 33 rotates around the rotating shaft 34 under the driving action of the driving component 32, and when the rotating component 33 rotates, the transmission direction (angle) of the membrane 11 supported by the first roller 331 is adjusted, so that the position deviation of the membrane 11 during the transmission process can be corrected.

[0043] In some embodiments, the rotating component 33 also includes a second roller body 332 parallel to the first roller body 331. The first roller body 331 and the second roller body 332 are used to support the diaphragm 11 and form a transmission plane that guides the transmission path of the diaphragm. The rotating shaft 34 extending in the vertical direction is perpendicular to the transmission plane. When the first roller body 331 and the second roller body 332 support the transmission of the diaphragm 11, the transmission plane of the diaphragm 11 is defined between the two roller bodies. When the rotating component 33 rotates, the transmission angle of the diaphragm 11 in the transmission plane is adjusted. Therefore, the position deviation of the diaphragm 11 during the transmission process can be corrected. The diaphragm 11 is jointly supported and transmitted by the first roller body 331 and the second roller body 332, and the transmission of the diaphragm 11 is relatively stable.

[0044] In some embodiments, the rotating component 33 as described above also includes: a rotating connection portion 333, which extends above the transmission plane and the extension direction is perpendicular to the rotation axis 34. Exemplarily, the rotating connection portion 333 can adopt a plate-like structure, and the surface of the plate-like structure is parallel to the transmission plane and perpendicular to the rotation axis 34, and one end of the rotation axis 34 is installed on the rotating connection portion 333. It can be understood that the plate-like structure facilitates the stable connection between the rotating connection portion 33 and the rotation axis 34; two roller connection portions 334, each roller connection portion 334 extends in a direction perpendicular to the rotating connection portion 333, and each roller connection portion 334 is respectively connected to one end of the rotating connection portion 333, and the first roller 331 and the second roller 332 are installed between the two roller connection portions 334 to obtain stable support for the roller connection portion 334.

[0045] The rotating connecting part 333 and the two roller connecting parts 334 extending above the transmission plane can form a stable frame as a basis for stably supporting the first roller 331 and the second roller 332. The first roller 331 and the second roller 332 supported stably can more stably transmit the diaphragm 11. In addition, the frame can adjust the transmission angle of the diaphragm 11 supported by the rollers as the rotating shaft 34 rotates.

[0046] In some examples, the first end of the rotating shaft 34 is rotatably connected to the base plate 31 through a bearing seat 335, and the second end of the rotating shaft 34 is fixedly mounted on the rotating connection portion 333. In some examples, the first end of the rotating shaft 34 is fixedly mounted on the base plate 31, and the second end of the rotating shaft 34 is rotatably connected to the rotating connection portion 333 through a bearing seat 335. The connection through the bearing seat 335 makes the mechanical support more stable and helps to improve the stability of the rotation. Specifically, it helps to ensure that the rotation is in the same plane. Although the example of using the bearing seat 335 to cooperate with the rotating shaft 34 to realize the rotation of the rotating component 33 has been introduced above, it can be understood that the specific structural form of the rotation driven by the rotating shaft 34 is not limited to the aforementioned form. For example, the first end of the rotating shaft 34 is directly rotatably connected to the base plate 31, the second end of the rotating shaft 34 is directly rotatably connected to the rotating connection portion 333, or one of the first end and the second end is directly rotatably connected to the corresponding component.

[0047] In some embodiments, the driving component 32 is rotatably mounted on the substrate 31, and the driving end of the driving component 32 is transmission-connected to one of the roller body connecting parts 334, and the driving end of the driving component 32 can be extended and reciprocated. In the extension direction of the rotating connecting part 333, the driving end of the driving component 32 drives the connected roller body connecting part 334, so that the roller body connecting part 334 can reciprocate, so that through the transmission connection, the driving end of the driving component 32 can make the rotating component 33 rotate as a whole in the plane, so as to facilitate the adjustment of the transmission angle of the diaphragm in the transmission plane.

[0048] In some embodiments, the driving component 32 includes an electric push rod cylinder, which is arranged on one side of the rotating component 33 (for example, it can be fixedly connected to the base plate 31), and the piston rod of the electric push rod cylinder is connected to one side of the rotating component 33 to drive the rotating component 33 to rotate around the rotating shaft 34. The electric push rod cylinder has good synchronization and is less dependent on maintenance, which is convenient for intelligent control, and stable rotation is obtained by the electric push rod cylinder. It can be understood that the specific structural form of the driving component 32 is not limited to the aforementioned form. For example, in other embodiments, the driving component 32 described above can also use components such as a motor, the output shaft of the motor is connected to the rotating shaft 34 through a coupling or a pulley assembly, and the motor drives the rotating shaft 34 to rotate to drive the rotating component 33 to rotate. The modular cooperation of the motor and the coupling or the pulley assembly is convenient for maintenance and replacement, and through the adjustment of the coupling and the pulley assembly, it is more convenient to finely adjust the step angle of rotation.

[0049] In some other embodiments of the present application, the aforementioned diaphragm transmission correction component 3 also includes a detection component 35 for detecting whether the diaphragm is deviated. The detection component 35 is usually arranged downstream of the rotating component 33. After the diaphragm 11 is supported and transmitted by the rotating component 33, the position information is promptly detected by the detection component 35 to determine whether the transmission direction is deviated, thereby facilitating timely correction of the transmission direction of the diaphragm 11.

[0050] As an embodiment, the detection component 35 includes a mounting rod 351 connected to the substrate 31, and two sensors 352 symmetrically installed on the mounting rod 351. The two sensors 352 are respectively arranged near the side edges of the diaphragm 11, and the distance between the two sensors 352 is smaller than the width of the diaphragm 11. Each sensor 352 is used to sense the position of the corresponding side edge of the diaphragm 11. The two sensors 352 are arranged to detect the positions of the two side edges of the diaphragm 11, so as to more accurately determine whether the transmission of the diaphragm 11 is deflected.

[0051] Exemplarily, the sensor 352 is a grating sensor, and the two sides of the diaphragm are respectively located in the sensing area of ​​a grating sensor. The grating displacement sensor 352 is based on optical interference and diffraction technology, and measures the moving distance of the light beam on the grating to achieve accurate measurement of the displacement of the object. It has good electrical insulation performance and is stable, safe and reliable.

[0052] The above describes the diaphragm transmission correction component 3. Now let's go back to the diaphragm transmission mechanism embodiment provided in this application. Figure 1 As shown, the diaphragm transmission mechanism is further described.

[0053] During the stacking operation, the distance between the coating assembly 6 and the stacking platform changes dynamically. When this distance change occurs, for example, when the distance changes from large to small, if the redundant diaphragm between the coating assembly 6 and the stacking platform is not pulled back for buffering in time, the diaphragm 11 will become wrinkled or too loose, which will affect the cyclic stacking operation and reduce the quality of the battery cell stacking.

[0054] The diaphragm buffer component 4 is arranged on the transmission path of the diaphragm and is located between the diaphragm transmission correction component 3 and the tension isolation component 5. By means of this arrangement, the film coating component can be as close as possible, and when the distance between the film coating component 6 and the lamination platform changes, the length of the diaphragm between the diaphragm transmission correction component 3 and the tension isolation component 5 is timely adjusted. Exemplarily, when the distance between the film coating component 6 and the lamination platform changes from large to small, the length of the diaphragm between the diaphragm transmission correction component 3 and the tension isolation component 5 changes from short to long, that is, the diaphragm redundancy caused by the change in the distance between the film coating component 6 and the lamination platform is pulled back to the cache, and when the distance between the film coating component 6 and the lamination platform changes from small to large, the length of the diaphragm between the diaphragm transmission correction component 3 and the tension isolation component 5 changes from long to short, that is, the diaphragm cached between the diaphragm transmission correction component 3 and the tension isolation component 5 is released to be transmitted between the film coating component 6 and the lamination platform.

[0055] In one embodiment, the diaphragm buffer assembly 4 includes a guide rail 41 and a fixed roller 42 arranged on the installation wall 7, and a sliding roller 43 slidably installed on the guide rail 41. The diaphragm located between the diaphragm transmission correction assembly 3 and the tension isolation assembly 5 is jointly supported and transmitted by the fixed roller 42 and the sliding roller 43, and the sliding roller 43 can slide back and forth on the guide rail 41. The reciprocating sliding can change the length of the diaphragm between the fixed roller 42 and the sliding roller 43, wherein: the guide rail 41 is arranged between the diaphragm transmission correction assembly 3 and the tension isolation assembly 5, and is located on a common side of the diaphragm transmission correction assembly 3 and the tension isolation assembly 5, and the distance from one end to the other end of the guide rail 41 relative to the diaphragm transmission correction assembly 3 (and the tension isolation assembly 5) is from near to far.

[0056] In specific implementation, the tension control component 2 in the diaphragm transmission mechanism may include a tension motor, a tension sensor and a swing roller assembly; the swing roller assembly supports and transmits the diaphragm, the tension sensor is installed on the tension motor, and the swing roller assembly is installed on the movable part of the tension motor; the tension sensor detects the tension change of the diaphragm passing through the swing roller assembly in real time, and controls the tension motor to drive the swing roller assembly to rotate forward or reverse, so as to adjust the tension degree of the diaphragm passing through the swing roller assembly, that is, to adjust the tension of the diaphragm.

[0057] In addition, during specific implementation, the tension barrier assembly 5 in the diaphragm transmission mechanism may include a vacuum adsorption roller installed on the installation wall 7, the vacuum adsorption roller is arranged on the transmission path of the diaphragm 11 and supports the diaphragm 11, and the vacuum adsorption roller is provided with an adsorption hole, which is connected to the vacuum generating equipment. The diaphragm 11 on the surface of the vacuum adsorption roller is adsorbed, so that the upstream tension barrier is disconnected to prevent it from being transmitted to the downstream to affect the cyclic stacking operation and reduce the quality of the battery cell stacking.
