[0060] See Figures 1 to 4 As shown, Embodiment 1 of this application provides an automatic wrinkle-removing system for diaphragms, including: a machine body 1, an arc height adjustment device 4, a control system, a first guide roller 2, and a second guide roller 3. The first guide roller 2 and the second guide roller 3 are rotatably mounted on the machine body 1, parallel and spaced apart. The arc height adjustment device 4 is mounted on the machine body 1, located between the first guide roller 2 and the second guide roller. The arc height adjustment device 4 includes multiple arc height adjustment components 42. The control system is electrically connected to the arc height adjustment device 4 to control the lifting and lowering movement of each arc height adjustment component 42. The diaphragm 9 extends sequentially through the first guide roller 2, the arc height adjustment device 4, and the second guide roller 3. The diaphragm 9 is located at the bottom of the first guide roller 2 and the second guide roller 3, and at the top of the arc height adjustment device 4. The limiting effect of the first guide roller 2 and the second guide roller 3 ensures that the diaphragm 9 can fully contact the arc height adjustment device 4, allowing the arc height adjustment device 4 to effectively act on the diaphragm 9 and improve the wrinkle-removing effect. The arc height adjustment device 4 of this application includes multiple arc height adjustment components 42.

[0061] In a possible implementation, the arc height adjustment assemblies 42 are arranged along a first direction, and each arc height adjustment assembly has a rotating member for contacting the diaphragm, and the rotating member can rotate at least around a first rotating axis parallel to the first direction. The first direction is parallel to the direction of the first guide roller, or the length direction of the first guide roller, so that the arc height adjustment device 4 can accurately remove the wrinkles of the diaphragm 9 according to the actual wrinkle position of the diaphragm 9 in the width range of the diaphragm 9, and the wrinkle removal effect is improved. Meanwhile, the arc height adjustment assemblies 42 are arranged along a second direction, and the second direction is from the first guide roller to the second guide roller. The second direction can be perpendicular to the first direction, or the second direction is perpendicular to the first rotating axis, so that the diaphragm 9 can be removed within a certain distance range in the movement direction of the diaphragm 9.

[0062] In the embodiments of the present application, the arc height adjustment assemblies 42 can be arranged in multiple rows and multiple columns, and the arc height adjustment device 4 can control the corresponding multiple arc height adjustment assemblies 42 to rise according to the size of the actual wrinkle area of the diaphragm 9, so that the diaphragm 9 forms a slope surface to remove the wrinkles, and the wrinkle removal effect is improved.

[0063] In a possible implementation, the arc height adjustment device 4 includes a seat body 41 fixed to the machine body 1, and each arc height adjustment assembly 42 is arranged in the seat body 41. The arc height adjustment assembly 42 includes a driving mechanism and an adjusting part 423 for contacting the diaphragm 9. The adjusting part 423 is movably arranged in the seat body 41, and the driving mechanism is arranged in the seat body 41. The driving mechanism and the adjusting part 423 are in transmission connection to drive the adjusting part 423 to move up and down.

[0064] The driving mechanism includes a rotating driving member 421 and a lead screw 422, and the adjusting part 423 includes a bracket 4231 and a rotating member 4232. The rotating member 4232 can be cylindrical, spherical or other shapes, and the shape of the rotating member 4232 is not limited in the present application. The bracket 4231 is movably arranged in the seat body 41, and the rotating member 4232 is rotatably connected to the bracket 4231. The rotating member 4232 is used to contact the diaphragm 9 to generate an arc surface on the diaphragm 9 to achieve the purpose of removing wrinkles. The bracket 4231 has a threaded groove, one end of the lead screw 422 is connected to the rotating shaft of the rotating driving member 421, and the lead screw 422 is threadedly connected to the threaded groove of the bracket 4231. The forward / reverse rotation of the rotating driving member 421 can drive the adjusting part 423 to move up and down. In the embodiments of the present application, the arc height adjustment assembly 42 adopts the lead screw 422 nut scheme to realize the up and down movement of the adjusting part 423, and has stable performance and high reliability.

[0065] The seat body 41 can include a housing, the rotary driving member 421 can be a motor, the rotary driving member 421 is located inside the housing, the support 4231 can include two side rods and a bottom rod, the bottom rod is connected to the bottom of the two side rods, the rotary member 4232 is located between the two side rods, and the rotary member 4232 is located at the top of the two side rods, and the rotary member 4232 is rotatably arranged.

Each rotary member 4232 is arranged in multiple rows and multiple columns.

[0066] The existing arc-shaped roller adopts rubber material to coat the roller surface for adjusting the arc height, and the friction coefficient is high. In the rotating process, friction is easy to occur, the surface appearance of the base film is damaged, foreign matter dust is easy to inlay, the diaphragm 9 is cut, the overall safety performance after the battery is assembled is affected, and in the running process, the power mechanism is easy to wear, affecting the service life. The diaphragm 9 contacts the rubber material, and a large amount of static electricity is easy to generate, causing the diaphragm 9 to be punctured and affecting the safety performance. In view of this, in the embodiment of the application, the material of the rotary member 4232 and the contact part of the film is upgraded from rubber to metal, the friction is reduced, the surface scratch of the diaphragm 9 is avoided, the consistency of the diaphragm 9 is reduced, the powder inlaid in the rubber material is prevented, the diaphragm 9 is cut, the positive and negative poles are short-circuited, the battery safety accident is affected. By adopting the metal structure, the static electricity value of the corresponding diaphragm 9 can also be eliminated, the diaphragm 9 is prevented from being punctured, and the safety performance of the product is improved.

[0067] In the diaphragm automatic wrinkle removal system, the static electricity value can be tested by a non-contact handheld static electricity detector, and a conventional static electricity detector can be used, such as SIMCO, Konavost, etc.

[0068] The following is a comparison table of the processing conditions of the conventional wrinkle removal system and the diaphragm automatic wrinkle removal system (the material of the rotary member 4232 contacting the film is upgraded from rubber to metal) at different vehicle speeds (Table 1). As can be seen from Table 1, by replacing the material of the rotary member 4232, the scratch defects generated in the production process are obviously reduced.

[0073] Embodiment two

[0074] The embodiment two of the present application provides a control method of the above-mentioned automatic crease-removing system for the diaphragm, comprising:

[0075] Step S1, the control system detects the crease amount of the diaphragm 9;

[0076] Step S2, the control system compares the crease amount with a preset value to determine the lifting amount of the arc height adjusting assembly 42;

[0077] Step S3, the control system controls the arc height adjusting assembly 42 to perform corresponding lifting action.

[0078] Specifically, in step S1, the control system divides the diaphragm 9 in the detection area into a plurality of crease areas according to the crease condition of the diaphragm 9 in the detection area, respectively acquires the crease amount of each crease area, and each crease area corresponds to a plurality of arc height adjusting assemblies 42;

[0079] The control system can divide the detection area into multiple creasing areas when the diaphragm 9 in the detection area has multiple creases, and determine the creasing amount of each creasing area. Each creasing area has a corresponding plurality of arc height adjustment assemblies 42 at the arc height adjustment device 4. That is, when the diaphragm segment in the current detection area moves to the top of the arc height adjustment device 4, each arc height adjustment assembly 42 corresponding to each creasing area is located at the bottom of the corresponding creasing area. The creasing area can be removed by controlling the lifting of the arc height adjustment assembly 42 corresponding to the creasing area.

[0080] In step S2, the control system calculates the lifting amount of each arc height adjustment assembly 42 corresponding to the creasing area according to the creasing amount of each creasing area. The creasing amount can be understood as the creasing size.

[0081] In step S3, the control system controls each arc height adjustment assembly 42 corresponding to each creasing area to perform corresponding lifting action.

[0082] Optionally, in step S2, the control system first determines the lifting amount of the target arc height adjustment assembly 42 corresponding to each arc height adjustment assembly 42 of the creasing area according to the creasing amount of the creasing area, and determines the lifting amount of each adjacent arc height adjustment assembly 42 according to the lifting amount of the target arc height adjustment assembly 42. The target arc height adjustment assembly 42 can be the arc height adjustment assembly 42 corresponding to the creasing vertex in the creasing area, or the target arc height adjustment assembly 42 can be the arc height adjustment assembly 42 corresponding to the middle position of the creasing area. The creasing amount of the creasing area can be the creasing amount of the creasing vertex of the creasing area. According to the creasing amount, the lifting amount of the target arc height adjustment assembly 42 can be determined, and the lifting height of other arc height adjustment assemblies 42 corresponding to the creasing area can be adaptively adjusted according to the target arc height adjustment assembly 42.

[0083] Regarding the calculation of the lifting amount of the target arc height adjustment assembly 42, a calibration coefficient can be first set:

[0084] The calibration coefficient X = 1 + (preset allowable deviation upper limit - preset allowable deviation lower limit) / (film thickness deviation upper limit - film thickness deviation lower limit). The calibration coefficient is used to compensate for the machining deviation. Then the lifting amount of the target arc height adjustment assembly 42 = (creasing amount detection value of the creasing area - preset value) x calibration coefficient X.

[0085] Specifically, the lifting amount of each arc height adjustment assembly 42 corresponding to each creasing area is determined by the following method:

[0086] The difference of the lifting amount of two adjacent arc height adjusting components 42 along the first direction is set as a first coefficient, and the lifting amount of the arc height adjusting component 42 far from the target arc height adjusting component 42 is smaller among the two adjacent arc height adjusting components 42;

[0087] The difference of the lifting amount of two adjacent arc height adjusting components 42 along the second direction is set as a second coefficient, and the lifting amount of the arc height adjusting component 42 far from the target arc height adjusting component 42 is smaller among the two adjacent arc height adjusting components 42.

[0088] Table 2 shows the lifting amount of each arc height adjusting component 42 corresponding to the creping area in the embodiment; wherein T is the first direction, M is the second direction, b is the first coefficient, and c is the second coefficient.
