At present, the tension of the battery pole piece is generally adjusted by a floating roll in the feeding process of the battery pole piece. Fig. 1 is a simplified schematic diagram of a winding mechanism in the related art. Referring to fig. 1, a battery tab 200 is wound on the sides of a first feed roller 300, a dancer 100, and a second feed roller 400 in this order. In the feeding process, if the tension of the battery pole piece 200 is too small, the adjusting floating roller 100 swings to the outer side of the battery pole piece 200, namely swings along the first direction a in fig. 1, so that the tension of the battery pole piece 200 is increased; if the tension of the battery pole piece 200 is too small, the dancer 100 swings to the inner side of the battery pole piece 200, that is, in the second direction B in fig. 1, thereby reducing the tension of the battery pole piece 200.

The applicant noticed that the position of the dancer 100 is related to the tension of the battery sheet 200, and the position of the dancer 100 needs to be detected in order to stabilize the tension of the battery sheet 200. However, in the related art, the position of the floating roller 100 is generally detected by using a rotary potentiometer or a linear potentiometer, but the detection results of the two potentiometers are not accurate enough, and the tension adjustment of the floating roller 100 is affected.

In view of the above, embodiments of the present application provide a dancer-roller position detecting device including a rotating roller, a detecting block, and a sensor, the rotating roller being connected to the dancer roller such that the dancer roller can swing around a rotation axis of the rotating roller. The sensor is used for detecting a detection distance L1 between the sensor and the detection block, and the detection distance L1 is used for representing the relative position of the detection block and the sensor. One of the detection block and the sensor (the assumed sensor) is fixedly arranged, the other one of the detection block and the sensor (the assumed detection block) is arranged at a position of the rotating roller, which is deviated from the rotating axis of the rotating roller, when the rotating roller rotates, the detection distance L1 changes, and the rotating angle alpha of the rotating roller and the detection distance L1 have a mapping relation. When using this floating roll position detection device, be connected the live-rollers with the floating roll, can drive the live-rollers rotation when the floating roll swings like this, thereby the live-rollers rotates and drives and detects the piece and rotate, make detection distance L1 change, because the turned angle alpha of live-rollers has the mapping relation with detection distance L1, thereby can calculate the turned angle alpha of live-rollers, because the turned angle alpha of live-rollers is equal with the swing angle of floating roll again, thereby can confirm the swing angle of floating roll. Because the rotation angle alpha of the rotating roller has a mapping relation with the detection distance L1, and the rotation angle alpha of the rotating roller is equal to the swing angle of the floating roller, the swing angle of the floating roller is in the mapping relation with the detection distance L1, the position of the floating roller can be determined as long as the detection distance L1 is accurately determined, the detection result is accurate, and the tension regulation of the floating roller cannot be influenced.

The device for detecting the position of the floating roller can be applied to a rolling system, so that the position of the floating roller can be accurately determined, the tension of a battery pole piece is stabilized, and smooth proceeding of a material feeding link of the battery pole piece is guaranteed.

The embodiment of the application provides a floating roll position detection device, and the floating roll position detection device can be used for a rolling system. Fig. 2 is a front view of a roller system according to some embodiments of the present application. Referring to fig. 2, the dancer roller position detecting device includes a rotating roller 10, and the rotating roller 10 is connected to a dancer roller 100 such that the dancer roller 100 can swing about a rotation axis of the rotating roller 10. Fig. 3 is a left side view of the rolling system without oscillating the dancer according to some embodiments of the present application, and fig. 4 is a left side view of the rolling system after oscillating the dancer according to some embodiments of the present application. Referring to fig. 3 and 4, the dancing roller position detection device further includes a detection block 20 and a sensor 30, the sensor 30 is used for detecting a detection distance L1 between the sensor 30 and the detection block 20, and the detection distance L1 is used for representing the relative position of the detection block 20 and the sensor 30. One of the detection block 20 and the sensor 30 is fixedly arranged relative to the rotating roller 10, the other of the detection block 20 and the sensor 30 is arranged at a position of the rotating roller 10, which is deviated from the rotating axis of the rotating roller 10, the detection distance L1 changes along with the rotation of the rotating roller 10, and the rotating angle alpha of the rotating roller 10 has a mapping relation with the detection distance L1.

In fig. 2 to 4, the sensor 30 is fixedly installed, and the sensing block 20 is installed at a position of the rotating roller 10 deviated from the rotation axis of the rotating roller 10, so that the sensor 30 is fixed and the sensing block 20 is movable, thereby preventing the sensor 30 from colliding with other devices during repeated movement and damaging the sensor 30. In other implementations, the detection block 20 may be fixedly disposed, and the sensor 30 may be disposed at a position of the rotating roller 10 deviated from the rotation axis of the rotating roller 10. For convenience of explanation, the following explanation of the present application will be given by taking as an example a case where the sensor 30 is fixedly provided and the detection block 20 is provided at a position deviated from the rotation axis of the rotating roller 10.

The rotating roller 10 is connected to the floating roller 100, and the swing axis of the floating roller 100 is the rotation axis of the rotating roller 10, so that when the floating roller 100 swings, the rotating roller is driven to rotate, and at this time, the swing angle of the floating roller 100 is equal to the rotation angle α of the rotating roller 10.

In the embodiment of the present application, the detection block 20 is disposed at a position of the rotating roller 10 that is offset from the rotational axis of the rotating roller 10, so that when the rotating roller 10 rotates, the detection block 20 also rotates, and the rotational axis of the detection block 20 is the rotational axis of the rotating roller 10. The detection distance L1 varies when the rotating roller 10 rotates.

In the embodiment of the present application, the shape of the detection block 20 is not limited, and the detection block 20 may have a cubic shape, a triangular prism shape, or the like.

In the embodiment of the present application, the material of the detection block 20 is not limited, for example, the material of the detection block 20 may be metal or nonmetal.

In the embodiment of the present application, the detection distance L1 is a distance between the sensor 30 and the detection block 20 along the extending direction C of the detection portion of the sensor 30. In some cases, the detection distance L1 is the minimum distance between the sensor 30 and the detection block 20; in other cases, the detection distance L1 is not the minimum distance between the sensor 30 and the detection block 20, and is related to the position relationship between the detection block 20 and the sensor 30.

In one implementation of the embodiment of the present application, there is a one-to-one mapping relationship between the rotation angle α of the rotating roller 10 and the detection distance L1.

In this embodiment, when the device for detecting the position of the floating roller is used in a rolling system, the rotating roller 10 is connected to the floating roller 100, the rotating roller 10 is driven to rotate when the floating roller 100 swings, the detecting block 20 also rotates, so that the detecting distance L1 between the detecting sensor 30 and the detecting block 20 changes, the rotating angle α of the rotating roller 10 can be determined by detecting the distance L1, and then the swinging angle of the floating roller 100 is determined by the rotating angle α of the rotating roller 10, because the initial position of the floating roller 100 is known, the position of the floating roller 100 can be determined by the swinging angle of the floating roller 100. Because the mapping relation exists between the rotation angle alpha of the rotating roller 10 and the detection distance L1, and the swing angle of the floating roller 100 is equal to the rotation angle alpha of the rotating roller 10, the position of the floating roller 100 can be determined as long as the detection distance L1 is accurately determined, and the detection result is more accurate.

Referring to fig. 2 to 4, the dancer position detection apparatus further comprises a connecting disc 40. The connection disc 40 is rigidly connected with the rotating roller 10, the rotation axis of the connection disc 40 is parallel to the rotation axis of the rotating roller 10, and the other of the detection block 20 and the sensor 30, which is arranged at a position deviated from the rotation axis of the rotating roller 10, is fixedly connected with the end surface of the connection disc 40.

In the embodiment of the present application, the rotation axis of the connection disc 40 is parallel to the rotation axis of the rotation roller 10, and the connection disc 40 is rigidly connected to the rotation roller 10, so that the rotation roller 10 can rotate to drive the connection disc 40 to rotate, and the rotation angle of the rotation roller 10 is equal to the rotation angle of the connection disc 40.

Illustratively, the detecting block 20 is fixedly connected with the end face of the connecting disc 40, and the detecting block 20 is located at a position of the connecting disc 40 deviated from the rotating axis of the connecting disc 40, and the rotating roller 10 can drive the detecting block 20 to rotate through the connecting disc 40.

As shown in fig. 3 and 4, the area of the end surface of the coupling disk 40 is larger than the area of the end surface of the rotatable roller 10, i.e., the circle on which the end surface of the coupling disk 40 is located is larger than the circle on which the end surface of the rotatable roller 10 is located.

In the embodiment of the present application, the connecting disc 40 is provided to install the detecting block 20, the circle where the end surface of the connecting disc 40 is located can be set to be larger, and the detecting block 20 is arranged on the connecting disc 40, so that compared with the case that the detecting block 20 is directly arranged on the rotating roller 10, the circle where the detecting block 20 is located when the detecting block 20 rotates is larger, when the rotating angle α of the rotating roller 10 is fixed, the distance of the detecting block 20 rotating is larger, that is, the change of the detecting distance L1 is larger, and the detecting block can be detected more easily, thereby further improving the accuracy of the detection.

Illustratively, the detection block 20 may be disposed at a position of the connecting disk 40 close to the side edge, which may make the variation of the detection distance L1 larger when the floating roller 100 swings, and further improve the detection accuracy.

Referring to fig. 2, the connection disc 40 is coaxially and fixedly connected with the rotating roller 10, and the detection block 20 is connected to an end surface of the connection disc 40 on a side far from the rotating roller 10.

The connecting disc 40 is coaxially and fixedly connected with the rotating roller 10, the structure is simpler, the detection block 20 is connected to the end face of the connecting disc 40, far away from the rotating roller 10, namely the detection block 20 is movable, and the sensor 30 is prevented from colliding with other devices in the repeated moving process to damage the sensor 30.

Referring to fig. 2, the apparatus for detecting a position of a dancing roll further comprises a connecting rod 50, the connecting rod 50 is coaxially and fixedly connected with the turning roll 10, and the connecting disk 40 is coaxially and fixedly connected with the connecting rod 50. The connection rod 50 extends in the same direction as the rotating roller 10, and the connection rod 50 rotates in synchronization with the rotating roller 10.

In the embodiment of the present application, the connection rod 50 is provided for connecting the rotating roller 10 and the connection disc 40, and the length of the connection rod 50 may be set as required, so that the position of the connection disc 40 is set, which is more convenient.

According to some embodiments of the present application, the sensor 30 is a fiber optic sensor.

An optical fiber sensor is a sensor that converts the state of an object to be measured into a measurable optical signal.

The optical fiber sensor has high sensitivity, can improve the accuracy of the whole floating roller position detection device, is not easy to damage, and reduces the operation and maintenance cost of the device.

Meanwhile, the optical line sensor has good electrical insulation performance, strong anti-electromagnetic interference capability and strong adaptability, and is easy to realize the remote monitoring of the measured signal.

According to some embodiments of the present application, the rotation angle α is equal to or greater than 0 degrees and equal to or less than 30 degrees.

The rolling system after the floating roller is swung as shown in fig. 4 is taken as an example to describe how the rotation angle α is calculated according to the detected distance L1. When the dancer 100 is in the initial position, referring to fig. 3 and 4, the detection distance L1 between the detection block 20 and the sensor 30 is constant and is denoted as L1 ₀ . And the distance L2 from the point C detected by the sensor 30 on the detection block 20 to the center of rotation of the detection block 20 is also known and determined at this time. When the floating roller 100 swings and the detecting block 20 rotates, as shown in fig. 4, the detecting block 20 moves in a direction away from the sensor 30, and the detecting distance L1 between the detecting block 20 and the sensor 30 increases and is marked as L1 ₁ At this time, L1 ₁ Greater than L1 ₀ Thereby, it can be detected that the rotation angle of the floating roll 100 is arctan (L1) ₁ -L1 ₀ ) L2, i.e. α = arctan (L1) ₁ -L1 ₀ ) and/L2. Since the initial position of the dancer 100 is known, knowing the angle of rotation α determines the position of the dancer 100.

In fig. 4, the detection block 20 moves away from the sensor 30, and the detection distance L1 between the detection block 20 and the sensor 30 increases such that L1 ₁ -L1 ₀ > 0, then α is greater than 0 °; of course, there is a case where the detection block 20 moves in a direction to approach the sensor 30, and the detection distance L1 between the detection block 20 and the sensor 30 decreases, and L1 is the case ₁ -L1 ₀ < 0, then α is less than 0. When the detection block 20 is not moved, α is equal to 0 °, indicating that the rotating roller 10 is not rotating, i.e., the floating roller 100 is not oscillating.

As shown in fig. 1, the dancer 100 may swing clockwise or counterclockwise. With reference to fig. 1 to 4, when the floating roller 100 swings clockwise, the rotating roller 10 is driven to rotate clockwise, and the rotating roller 10 rotates clockwise to drive the detecting block 20 to rotate clockwise, so that the detecting block 20 moves towards the direction close to the sensor 30, and at this time, the detecting distance L1 between the detecting block 20 and the sensor 30 is reduced, and α is smaller than 0 °; the floating roller 100 drives the rotating roller 10 to rotate anticlockwise when swinging anticlockwise, the rotating roller 10 rotates anticlockwise to drive the detecting block 20 to rotate anticlockwise, the detecting block 20 moves towards the direction far away from the sensor 30, the detecting distance L1 between the detecting block 20 and the sensor 30 is increased at the moment, alpha is larger than 0 degrees, namely the swinging direction of the swinging roller can be determined through the relation between alpha and 0.

In the embodiment of the application, the tension of the battery pole piece does not change greatly, so the rotation angle of the floating roller 100 in the rolling system is generally small, the rotation angle alpha is limited, and the phenomenon that the feeding of the battery pole piece is influenced by the overlarge swing of the floating roller 100 is avoided.

Some embodiments of the present application provide a floating roller position adjusting apparatus including the floating roller position detecting device in the above-described embodiments and an adjusting device electrically connected to the sensor 30, the adjusting device being configured to adjust the swing of the floating roller 100 according to the detection distance L1.

In the embodiment of the present application, the adjusting device may directly adjust the swing of the dancer 100 or indirectly adjust the swing of the dancer 100.

In the embodiment of the present application, the actual position of the dancer 100 is determined based on the detection distance L1 detected by the dancer position detection means, and the adjustment means adjusts the dancer 100 to swing based on the actual position and the set position of the dancer 100 so that the dancer 100 swings to the set position.
