The application material belt deviation correcting device is used for correcting the position in material area, and material belt deviation correcting device includes: the fixing base 10 is provided with a guide shaft 100; the deviation rectifying roller 12, the deviation rectifying roller 12 comprises a swinging support shaft 120 and a roller 122 sleeved on the swinging support shaft 120; in actual use, the tape will pass around the surface of the roller 122; the swing support shaft 120 is provided with an inner cavity, a joint bearing 124 is arranged in the inner cavity, and the joint bearing 124 is arranged on the guide shaft 100 in a sliding manner; the driving mechanism 14, the driving mechanism 14 is used for driving one end of the swing supporting shaft 120 close to the fixed seat 10 to rotate around the knuckle bearing 124, so as to adjust the position of the surface of the roller 122 and further realize the correction of the position of the material belt passing through the surface of the roller 122.
In the material belt deviation rectifying device of the application, the rectifying roller 12 comprises a swing supporting shaft 120 and a roller 122 sleeved on the swing supporting shaft 120, a joint bearing 124 is arranged in an inner cavity of the swing supporting shaft 120, one end of the swing supporting shaft 120 close to the fixed seat 10 is driven to rotate around the joint bearing 124 through the driving mechanism 14, the swing supporting shaft 120 drives the roller 122 to swing when swinging, and then the position of the surface of the roller 122 can be adjusted to rectify the position of the material belt wound on the surface of the roller 122; and because the knuckle bearing 124 is slidably disposed on the guide shaft 100, that is, the swing support shaft 120 is also sleeved on the guide shaft 100, so that the swing angle of the swing support shaft 120 is limited by the guide shaft 100, and one end of the swing support shaft 120 close to the fixed seat 10 rotates at a small angle around the knuckle bearing 124, that is, the position of the material belt wound around the surface of the roller 122 is subjected to small-angle swing deviation correction, so as to improve the winding quality of the battery cell and further improve the product yield.
Further, the drive mechanism 14 includes a drive assembly 140 and a connection assembly 142; the connecting assembly 142 is connected to an end of the swing support shaft 120 close to the fixed seat 10, and the driving assembly 140 is configured to drive the connecting assembly 142 to move in a direction perpendicular to the axial direction of the guide shaft 100, so as to drive the end of the swing support shaft 120 close to the fixed seat 10 to rotate around the joint bearing 124. It can be understood that, since the connection component 142 is connected to the end of the swing support shaft 120 close to the fixed seat 10, the connection component 142 is driven by the driving component 140 to move along the direction perpendicular to the axial direction of the guide shaft 100, and then the end of the swing support shaft 120 close to the fixed seat 10 can be driven to move along the direction perpendicular to the axial direction of the guide shaft 100, and since the joint bearing 124 disposed in the inner cavity of the swing support shaft 120 is slidably disposed on the guide shaft 100, the swing support shaft 120 as a whole cannot move along the direction perpendicular to the axial direction of the guide shaft 100, but the end of the swing support shaft 120 close to the fixed seat 10 rotates around the joint bearing 124.
Specifically, as shown in fig. 3, the joint bearing 124 includes a sliding portion 1240 slidably provided on the guide shaft 100, and a rotating portion 1242 fitted around the outside of the sliding portion 1240. The sliding portion 1240 may slide on the guide shaft 100, and the rotating portion 1242 may rotate around the sliding portion 1240; therefore, when the driving assembly 140 drives the connecting assembly 142 to move the end of the swing support shaft 120 close to the fixed seat 10 in a direction perpendicular to the axial direction of the guide shaft 100, the swing support shaft 120 drives the rotating portion 1242 to rotate around the sliding portion 1240, and the swing support shaft 120 drives the sliding portion 1240 to move along the guide shaft 100. It will be appreciated that at this time, not only does the end of the swing support shaft 120 near the fixed base 10 rotate about the joint bearing 124, but the joint bearing 124 itself slides along the guide shaft 100.
As an example, the driving assembly 140 of the present application includes a driving motor 1400 and a lead screw 1402; the lead screw 1402 may include a lead screw main body and a lead screw nut sleeved on the lead screw main body, the lead screw main body is rotatably supported on the fixing base 10, and an extending direction of the lead screw main body is perpendicular to an axial direction of the guide shaft 100; the feed screw nut is connected with the connecting assembly 142; the driving motor 1400 is disposed on the fixing base 10, an output end of the driving motor 1400 is connected to one end of the lead screw main body through the coupling 1404, and the driving motor 1400 is configured to drive the lead screw main body to rotate so as to drive the lead screw nut to move along an extending direction of the lead screw main body, and further drive the connecting assembly 142 connected to the lead screw nut to move along a direction perpendicular to an axial direction of the guide shaft 100. It can be understood that, through the connection between the lead screw nut and the connection component 142, when the driving motor 1400 drives the lead screw main body to rotate, the lead screw nut sleeved on the lead screw main body can move along the lead screw main body, and since the extending direction of the lead screw main body is perpendicular to the axial direction of the guide shaft 100, the lead screw nut can drive the connection component 142 connected with the lead screw nut to move along the direction perpendicular to the axial direction of the guide shaft 100. In addition, the driving motor 1400 drives the material belt correction device to correct the position of the material belt, and the material belt correction device is high in response speed and correction efficiency.
Further, the connection assembly 142 includes a connection block 1420 connected to the lead screw nut, a rotation shaft 1422 disposed on the connection block 1420, and a swing frame 1424 connected to the rotation shaft 1422. It can be understood that, when the driving motor 1400 drives the lead screw body to rotate so that the lead screw nut moves along the extending direction of the lead screw body, the lead screw nut drives the connecting block 1420 and the rotating shaft 1422 to move along the direction perpendicular to the axial direction of the guiding shaft 100, and the swing frame 1424 moves along the direction perpendicular to the axial direction of the guiding shaft 100 along with the rotating shaft 1422; since the end of the swing support shaft 120 close to the fixed seat 10 is mounted on the swing frame 1424, when the swing frame 1424 moves along the direction perpendicular to the axial direction of the guide shaft 100 along with the rotating shaft 1422, the end of the swing support shaft 120 close to the fixed seat 10 is actually driven to rotate around the joint bearing 124, and to realize that the end of the swing support shaft 120 close to the fixed seat 10 rotates around the joint bearing 124, the swing frame 1424 also rotates around the rotating shaft 1422 while moving along the direction perpendicular to the axial direction of the guide shaft 100 along with the rotating shaft 1422.
Please refer to fig. 1 to fig. 4, wherein fig. 4 is a schematic diagram of the working principle of the material belt deviation rectifying device of the present invention. It can be understood that a1 and a2 are positions of the knuckle bearing 124 comprising a sliding part 1240 slidably disposed on the guide shaft 100 and a rotating part 1242 sleeved outside the sliding part 1240, wherein a1 is an initial position of the knuckle bearing 124, and a2 is a position of the corrected knuckle bearing 124; b1 and B2 are positions of the rotating shaft 1422, wherein B1 is an initial position of the rotating shaft 1422, and B2 is a position of the corrected rotating shaft 1422; since not only the end of the swing support shaft 120 close to the fixed base 10 rotates around the joint bearing 124 but also the joint bearing 124 itself slides along the guide shaft 100 when the driving assembly 140 drives the connecting assembly 142 to move the end of the swing support shaft 120 close to the fixed base 10 in a direction perpendicular to the axial direction of the guide shaft 100, the actual center of rotation of the end of the swing support shaft 120 close to the fixed base 10 is not at the joint bearing 124, but at a position close to point C, i.e., the instantaneous center of rotation is at and around point C. Preferably, the center of the initial position B1 of the rotation shaft 1422 may be located on an extension of the right side of the deviation rectification roller 12, and the point C is located at the midpoint of the right side of the deviation rectification roller 12. In a specific embodiment, when the driving motor 1400 drives the lead screw body to rotate to drive the lead screw nut, the connecting block 1420 connected to the lead screw nut, and the rotating shaft 1422 to move rightward, the swing frame 1424 moves along the rotating shaft 1422 in a direction perpendicular to the axial direction of the guiding shaft 100, and drives the end of the swing support shaft 120 close to the fixing base 10 to rotate around the knuckle bearing 124, at this time, the rotating portion 1242 rotates around the sliding portion 1240, and at the same time, the swing support shaft 120 drives the sliding portion 1240 to move towards the end close to the fixing base 10 along the guiding shaft 100, so that the end of the swing support shaft 120 close to the fixing base 10 rotates around the rotation center C, that is, the swing support shaft 120 realizes an anticlockwise swing angle through the knuckle bearing. Similarly, when the driving motor 1400 drives the lead screw body to rotate to drive the lead screw nut, the connecting block 1420 connected to the lead screw nut, and the rotating shaft 1422 to move leftward, the rotating portion 1242 rotates around the sliding portion 1240, and the swing support shaft 120 drives the sliding portion 1240 to move toward the end far away from the fixing base 10 along the guide shaft 100, at this time, the swing support shaft 120 can swing clockwise by an angle through the joint bearing 124.
Please refer to fig. 1 to fig. 5, wherein fig. 5 is a schematic diagram of a deviation rectifying principle of the material belt deviation rectifying device of the present invention. It can be understood that, in the actual production process, when the tape is deviated, for example, the actual center line L1 of the tape before deviation correction is parallel to the theoretical center line L2, the deviation correcting roller 12 needs to rotate clockwise around the rotation center C to drive the point D where the corrected actual center line L3 intersects the theoretical center line L2 when the tape is delivered from the deviation correcting roller 12, to be located on the left side of the deviation correcting roller 12, so that the center line of the tape is corrected to the theoretical center line L2 when the tape is delivered from the left side of the deviation correcting roller 12 and is delivered by the next passing roller.
Referring to fig. 1, as an alternative embodiment, the driving mechanism 14 further includes a guiding assembly 144, the guiding assembly 144 includes a base 1440, a sliding rail 1442 fixedly disposed on the base 1440, and a sliding member 1444 slidably connected to the sliding rail 1442, the sliding member 1444 is connected to the connecting block 1420; when the lead screw nut drives the connecting block 1420 to move in a direction perpendicular to the axial direction of the guide shaft 100, the connecting block 1420 drives the sliding member 1444 to slide on the sliding rail 1442. It can be understood that the extending direction of the sliding rail 1442 should be parallel to the extending direction of the lead screw body, so that when the lead screw nut drives the connecting block 1420 to move along the direction perpendicular to the axial direction of the guide shaft 100, the connecting block 1420 can drive the sliding member 1444 to slide on the sliding rail 1442, so as to enhance the moving accuracy and stability of the connecting block 1420 and the rotating shaft 1422, and thus, the deviation rectification accuracy of the material belt deviation rectification device can be improved. Specifically, the slider 1444 includes a slider 14440 slidably disposed on the slide rail 1442, a moving plate 14442 connected to the slider 14440, and a driving block 14444 mounted on the moving plate 14442, the driving block 14444 being connected to the connecting block 1420.
Referring to fig. 3, as an implementation manner, the roller 122 is sleeved on the swing supporting shaft 120 through a bearing 1220, one end of the swing supporting shaft 120 away from the fixing base 10 is sleeved with a lock nut 126, and one end of the lock nut 126 close to the fixing base 10 abuts against the bearing 1220. The bearing 1220 is prevented from moving in the axial direction of the guide shaft 100 by pressing the bearing 1220 with the lock nut 126.
Further, an end cover 128 is disposed on a side of the lock nut 126 away from the fixing base 10, and an end of the end cover 128 close to the fixing base 10 abuts against an end of the swing support shaft 120 away from the fixing base 10. By the end cap 128 abutting the upper end of the swing support shaft 120, the swing support shaft 120 can be prevented from moving in the axial direction of the guide shaft 100.
