Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
The invention provides a pole piece winding and unwinding device, which is shown in fig. 1-3, and comprises a machine base 1, a supporting seat 2, a pair of shaft seats 3, a pair of shaft posts 4 and a receiving roller 5, wherein the shaft seats 3 are connected with the supporting seat 2 through a first screw rod 23 and a first sliding rail 21; a shaft connecting column 4 is connected with the driving wheel; the machine base 1 is connected with the supporting seat 2 through a second sliding rail 22;
Also comprises a detector 6, a control system and a first cylinder 7; the receiving roller 5 is used for receiving the pole piece wound or unwound by the winding roller 0; the detector 6 is arranged at the edge of the roller body of the receiving roller 5; the detector 6 is used for detecting a displacement difference signal between the winding roller 0 and the pole piece and transmitting the displacement difference signal to the control system; the control system is used for carrying out logical operation according to signals and instructing the first air cylinder 7 to drive the supporting seat 2 to slide relative to the base 1.
The pole piece winding and unwinding device adjusts the distance between the shaft connecting posts 4 through matching the shaft connecting base 3 and the first sliding rail 21, so as to adapt to pole piece winding rollers 0 with different widths. In the winding and unwinding process, the offset generated when the pole piece winding rollers 0 with different widths are wound and unwound is different, and the distance between the supporting seat 2 and the machine base 1 is monitored in real time and adjusted in real time, so that the winding and unwinding can be kept in parallel in real time, and the adverse stress between the pole piece and the detection device is reduced.
In order to improve the fastening firmness of the shaft connecting column 4 to the winding roller 0 and avoid the bad stress of the winding roller 0 to the shaft connecting column 4, as shown in fig. 4, the shaft connecting column 4 comprises a shaft cap 41 and a shaft rod 42, and the shaft cap 41 is conical and is provided with long slots 411 uniformly distributed along the circumference. That is, the conical design is helpful to clamp the roller 0, and the design of the long slot 411 can improve the clamping degree of the roller 0 and the shaft connecting column 4 and has certain elastic deformation, so that the roller is prevented from being clamped or marks are left on the shaft connecting column 4.
According to the pole piece winding and unwinding device provided by the invention, the shaft cap 41 and the shaft rod 42 are linked through the axial bearing ball bearing and the radial bearing ball bearing which are sleeved on the shaft rod 42. I.e. during high speed rotation, stresses to which the shaft cap 41 is subjected in the radial and axial directions are effectively prevented from being transmitted to the shaft 42. The service life of the shaft 42 is improved.
In the pole piece winding and unwinding device, one shaft connecting column 4 is connected with a driving wheel, the other shaft connecting column 4 is connected with a second air cylinder 8, and the pushing direction of the second air cylinder 8 is parallel to the axial direction of the shaft connecting column 4. In the dynamic winding and unwinding process, the radial generated bad stress can be effectively avoided, and therefore dynamic clamping force balance is achieved.
In the pole piece winding and unwinding device, a first cylinder 7 is connected with a machine base 1 through a push arm 9. The first cylinder 7 drives the pushing arm 9 to displace, so that the supporting seat 2 is pushed to displace in parallel relative to the machine base 1. The first cylinder 7 is arranged in parallel relative to the shaft-connection column 4, the push arm 9 is arranged vertically relative to the shaft-connection column 4, and the push arm 9 is fixedly connected with the support seat 2 by a plurality of screws.
The first cylinder 7 comprises a first cylinder 71 and a first rod 72, the first cylinder 71 is pivotally connected to the base 1, and the first rod 72 is pivotally connected to the push arm 9. By adopting the connection mode, the first cylinder 7 only transmits the driving force in the axial direction, and the radial bad stress can be effectively reduced.
The principle of the first cylinder 7 pushing the support base 2 to displace in parallel is as follows: after the air cylinder is instructed by the control system, the pressure in the first cylinder body 71 changes, so that the rod body is pushed to axially displace, the push arm 9 is driven to axially displace, and the supporting seat 2 is further displaced in parallel relative to the base 1.
In order to improve the flatness of the displacement of the push arm 9 against the support base 2, the push arm 9 is provided with a downwardly extending catch projection 91. Namely, when the pushing arm 9 pushes the supporting seat 2 to displace, the pushing arm is a T-shaped stress surface, so that the pushing arm can be pushed in the axial direction.
The second sliding rail 22 is used as a sliding connection part of the supporting seat 2 and the machine base 1, and the preferred shape of the second sliding rail is I-shaped, so that the supporting seat 2 and the machine base 1 can be effectively prevented from being dislocated.
In order to improve the connection stability between the support base 2 and the base 1, a slider 11 matched with the second slide rail 22 may be further disposed on the base 1. At least two slides 11 are provided on each second slide 22. The supporting seat 2 is provided with a limiting block 24 matched with the sliding block 11 so as to prevent the sliding block 11 from dislocation.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
