Description

Technical Field

[0001] The utility model belongs to the technical field of winding and unwinding devices, and particularly relates to a swing roller mechanism and a roller press. Background Art

[0002] In the rolling and slitting machines in the secondary battery industry, the tension on both sides of the pole piece is often unstable after rolling, resulting in inconsistent states of the membrane surfaces on both sides of the pole piece between the rollers. One membrane surface is tightened while the other is in a sunken state, causing the pole piece to be easily wrinkled at the pull-through and swing rollers. Moreover, due to ground subsidence, the rolling equipment is segmented, and the settlement of the main section and the pull-through section are inconsistent, resulting in large horizontal changes between the main section roller and the pull-through section roller, which is also very easy to cause wrinkles at the pull-through and swing rollers.

[0003] The pole piece is wrinkled when it passes through the swing roller, that is, one end of the pole piece passing through the swing roller is loose and the other end is tight, and the loose end is easy to wrinkle and needs to be tightened. In the prior art, the two ends of the swing roller in most of the split pull swing roller mechanisms are fixed on the swing arm and cannot be adjusted, so the tightness of the two ends of the pole piece cannot be adjusted. Utility Model Content

[0004] The purpose of the utility model is to provide a swing roller mechanism to solve the above-mentioned technical problems, so as to achieve the effect of adjusting the tightness of the pole piece passing through the swing roller.

[0013] Furthermore, the linkage member is a screw rod, one end of which is connected to the driving end of the driving member, and the other end of which is threadedly connected to the bearing seat;

[0014] Wherein, the driving member is used to drive the screw to rotate.

[0015] Furthermore, the driving component is a servo motor.

[0016] Furthermore, the driving member is a cylinder, and the linkage member is a push rod.

[0017] Furthermore, the swing arm further comprises:

[0018] The bearing seat is installed in the slide groove, and the bearing seat can be moved and adjusted along the Y direction of the slide groove.

[0019] Furthermore, the displacement sensor is an electronic displacement ruler, and a measuring end of the electronic displacement ruler abuts against the bearing seat in the Y direction.

[0020] A roller press comprises a tension roller and any one of the swing roller mechanisms described above, wherein the pole piece passes through the swing roller mechanism and the tension roller in sequence.

[0021] Furthermore, it also includes a pressure sensor, which is arranged at both ends of the tension roller in the axial direction, and is used to detect the tension on both sides of the pole piece after being rolled by the tension roller and feed it back to the swing roller mechanism.

[0022] The beneficial effects of the utility model are:

[0023] By setting the swing roller mechanism, the driving mechanism is used to control one or both ends of the roller of the swing roller mechanism to move along the Y direction, so that the two ends of the roller form an angle deviation in the X direction, so that the pole piece passing through the roller can be kept tight on both sides in the X direction, and the pole ear wrinkles in the middle of the pole piece are eliminated, effectively reducing the scrap amount caused by wrinkling at the pull-out swing roller due to large changes in the membrane surface state of the pole piece after rolling; and reducing the equipment debugging production time and improving production efficiency.

[0031] Embodiment 1:

[0032] This embodiment provides a swing roller mechanism, including:

[0033] Two swing arms 1, each of which is provided with a bearing seat 2;

[0034] A roller 3, wherein both ends of the roller 3 are respectively installed in two bearing seats 2, wherein at least one bearing seat 2 can be moved and adjusted along the swing arm 1Y direction;

[0035] The driving mechanism is installed on the swing arm 1 and is used to drive the bearing seat 2 to move and adjust along the Y direction.

[0036] In the present technical solution, a bearing seat 2 is arranged on a swing arm 1 and can move along the Y direction. The pole piece after rolling passes through a swing roller mechanism, and the roller 3 of the swing roller mechanism pulls the pole piece to pass through. The driving mechanism on the swing arm 1 controls a bearing seat 2 to move along the Y direction of the swing arm 1, so that the roller 3 is inclined at a certain angle along the X direction, so that the pole piece passing through the roller 3 can be pulled by the roller 3 on both sides in the X direction to keep it taut and not easy to wrinkle.

[0037] It is worth mentioning that the bearing seats 2 on the two swing arms 1 can also be arranged to move along the Y direction. By setting two driving mechanisms to respectively control the movement of the two bearing seats 2 in the Y direction, a certain angle deviation is formed between the two ends of the roller 3, so that the pole pieces of the wiring passing through the roller 3 can be kept taut on both sides in the width direction.

[0038] In summary, by setting up the swing roller mechanism, the driving mechanism is used to control one or both ends of the roller 3 of the swing roller mechanism to move along the Y direction, so that the two ends of the roller 3 form an angle deviation in the X direction, so that the pole piece passing through the roller 3 can be kept tight on both sides in the X direction, and the wrinkles of the pole ear in the middle of the pole piece are eliminated, which effectively reduces the scrap amount caused by wrinkling at the pull-out swing roller due to the large change in the membrane surface state of the pole piece after rolling; and reduces the equipment debugging production time and improves production efficiency.

[0043] By setting the displacement transmission device 4, the distance moved by one or both ends of the roller 3 in the Y direction can be accurately measured, so as to more accurately control the angular deviation formed by the two ends of the roller 3 in the X direction within a suitable range, so as to achieve the best wrinkle removal effect of the swing roller mechanism.

[0051] Furthermore, the driving component 5 is a servo motor.

[0052] In this technical solution, the screw is rotatably mounted on the bearing seat 2 of the swing arm 1, and the servo motor controls the screw to rotate, so that the threaded connection amount between the bearing seat 2 and the screw changes, thereby realizing the movement of the bearing seat 2 in the Y direction.

[0053] It is worth mentioning that the driving mechanism can also use other mechanisms that can realize the movement of the bearing seat 2 along the Y direction, for example, the driving member 5 and the linkage member 6 are respectively selected from a cylinder and a push rod, and the cylinder drives the push rod to move the bearing seat 2 along the Y direction. Preferably, a servo motor and a lead screw are used to realize the accurate and smooth movement of the bearing seat 2.
