Referring to fig. 1, an embodiment of the present invention provides a deviation rectifying and roller passing device, which includes a roller 10, a first driving assembly 20 and a second driving assembly 30.
The first driving assembly 20 is used for driving the first end of the roller 10 to move along the first direction, and the first driving assembly 20 is in sliding fit with the first end of the roller 10 in the second direction, and the first end of the roller 10 can rotate around the third direction while sliding.
The second driving assembly 30 is configured to drive the second end of the over-roller 10 to move along the first direction, and the second driving assembly 30 is slidably engaged with the second end of the over-roller 10 in the second direction, and the second end of the over-roller 10 can rotate around the third direction while sliding.
The first direction, the second direction and the third direction are not parallel to each other.
In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other, the first direction is a vertical direction, the second direction is an axial direction of the passing roller 10, and the third direction is a horizontal direction perpendicular to the vertical direction and the axial direction of the passing roller 10.
By adopting the deviation rectifying roller 10 device, when the material belt passes through the roller 10, the first driving component 20 and/or the second driving component 30 can drive the roller 10 to respectively move at two ends in a first direction perpendicular to the belt surface of the material belt, so that the two ends of the roller 10 move and rotate in a second direction relative to the first driving component 20 and/or the second driving component 30, and the roller 10 tilts and swings in the width direction of the material belt, so that the material belt is rectified in the axial direction (namely in the second direction) of the roller 10.
Specifically, when the material belt is offset towards the first end of the passing roller 10, the first end of the passing roller 10 can be driven by the first driving component 20 to move upwards along the first direction, and at the moment, the second end of the passing roller 10 is driven by the roller body to move towards the first end along the second direction, and simultaneously rotates clockwise around the third direction, so that the whole passing roller 10 is inclined towards the second end of the passing roller 10, and the material belt moves towards the second end of the passing roller 10 along the inclined direction of the passing roller 10 for deviation correction; similarly, when the material belt is offset towards the second end of the passing roller 10, the second driving assembly 30 drives the passing roller 10 to incline towards the first end of the passing roller 10, so that the material belt can move towards the first end of the passing roller 10 for deviation correction.
Thus, by controlling the first driving assembly 20 and the second driving assembly 30, the material belt can be rectified back and forth in two directions and rectified in rotation around the third direction. In addition, in the deviation rectifying process, the two ends of the passing roller 10 can be controlled to move at the same time, so that the inclination degree and direction of the passing roller 10 can be quickly adjusted according to the deviation change amount, and the quick response and high-precision adjustment of deviation rectifying of the material belt can be realized.
Meanwhile, the first driving assembly 20 and the second driving assembly 30 can also drive the two ends of the passing roller 10 to move by the same distance, so that the passing roller 10 translates in the first direction, and the integral deviation correction of the material belt in the first direction is realized.
Compared with the existing single-roller deviation rectifying structure, the invention not only can realize bidirectional deviation rectifying of the material belt, but also has higher deviation rectifying precision, can further improve the processing quality of the battery and reduce the rejection rate.
In one embodiment of the present invention, the apparatus for correcting skew passing through rollers 10 further comprises:
a first detector 41 for detecting a change in pressure applied to the first end of the over-roller 10;
and/or a second detector 42 for detecting a change in pressure applied to the second end of the over-roll 10.
Specifically, the first detector 41 may be disposed at a lower side of the first end of the over-roller 10 to be in contact with the over-roller 10. The second detector 42 may be disposed below the second end of the over-roller 10 in contact with the over-roller 10. The first detector 41 and the second detector 42 each employ a pressure sensor. The pressure applied to the pass roller 10 is applied as the web passes the pass roller 10, and the pressure received at the ends of the pass roller 10 remains substantially constant when the web is in the neutral position of the pass roller 10, and increases at the biased end when the web is deflected. By detecting the pressure change across the roll 10, the direction of the web offset and the degree of offset can be known.
Specifically, an increase in the pressure applied to the end of the overroller 10 indicates that the web is offset toward the end, and the greater the pressure, the greater the degree of offset. Therefore, by providing pressure sensors at both ends of the passing roller 10, the pressure sensor can detect the pressure change at both ends of the passing roller 10 to feed back the deviation correcting effect in real time.
Referring to fig. 1 to 3, in the present embodiment, a first detector 41 is provided at the lower side of a first end of the over-roller 10, a second detector 42 is provided at the lower side of a second end of the over-roller 10, and pressure changes at both ends of the over-roller 10 are detected by the first detector 41 and the second detector 42, so that the first driving assembly 20 and the second driving assembly 30 are driven according to the detected pressure changes to adjust a height difference between both ends of the over-roller 10, thereby changing an inclination direction of the over-roller 10, and realizing deviation correction of a web in a width direction.
In other embodiments, a first detector 41 may also be optionally provided at a first end of the over-roll 10 or a second detector 42 may be provided at a second end of the over-roll 10. Taking the example of providing the first detector 41 at the first end of the over-roller 10, each time the first detector 41 detects a gradual increase in pressure, the first end of the over-roller 10 is driven to move up by the first driving assembly 20 until the first detector 41 detects a pressure value within a set range. When the first detector 41 does not detect the pressure change for a preset time, it can be determined that the material web is shifted toward the second end of the over-roller 10, at which time the second end of the over-roller 10 is driven by the second driving assembly 30 to move upward in the first direction until the first detector 41 can detect the pressure change.
It should be noted that the pressure sensors are not limited to be disposed at the lower sides of the two ends of the roller 10, but may be disposed at the upper sides of the two ends of the roller 10, and the detection effect can be achieved. When the pressure sensor is disposed on the upper end side of the passing roller 10, for example, the pressure sensor is disposed on the upper side of the first end of the passing roller 10 and is used for detecting whether the material belt is offset towards the second end of the passing roller 10, if the pressure sensor detects the pressure increase, the material belt is offset towards the second end of the passing roller 10, and the second end of the passing roller 10 can be driven to move upwards along the first direction by the second driving component 30, so that the material belt moves towards the first end of the passing roller 10 for deviation correction until the pressure detection pressure value is within the set range.
It should also be noted that when the first detector 41 and the second detector 42 are employed at the same time, it is preferable that the first detector 41 and the second detector 42 are disposed on the same side, for example, the first detector 41 and the second detector 42 are disposed on the first end lower side of the passing roller 10 and the second end side lower side of the passing roller 10, respectively, or the first detector 41 and the second detector 42 are disposed on the first end upper side of the passing roller 10 and the second end side upper side of the passing roller 10, respectively. Thereby facilitating detection of pressure changes across the roller 10.
In another embodiment of the present invention, the apparatus for correcting skew passing through rollers 10 further comprises:
a first detector 41 for detecting a change in displacement between the first end of the over-roller 10 and a detection reference position;
and/or a second detector 42 for detecting a change in displacement between the second end of the over-roll 10 and a detection reference position.
Specifically, the first detector 41 may be disposed at a lower side of the first end of the over-roller 10 to detect a displacement variation in the first direction between the first end of the over-roller 10 and the detection reference position, and the second detector 42 may be disposed at a lower side of the second end of the over-roller 10 to detect a displacement variation in the first direction between the second end of the over-roller 10 and the detection reference position. The first detector 41 and the second detector 42 may each employ a laser ranging sensor. Thus, the deviation correcting effect can be fed back in real time by detecting the swing amplitude of the two ends of the passing roller 10.
Taking the first detector 41 as an example, when the first detector 41 is provided at the lower side of the first end of the over roller 10, the movement of the first end of the over roller 10 in the first direction can be detected by the first detector 41. When the material belt is offset towards the second end of the passing roller 10, the passing roller 10 can be made to tilt towards the second end of the passing roller, at this time, the distance value detected by the first detector 41 is increased, the greater the distance value is, the greater the inclination degree of the passing roller 10 is, the greater the offset degree of the material belt is, and then the second end of the passing roller 10 can be driven by the second driving assembly 30 to move along the first direction, so that the material belt is rectified towards the first end of the passing roller 10. Similarly, when the material strip is offset toward the first end of the passing roller 10, the distance detected by the first detector 41 decreases, and the first end of the passing roller 10 can be driven by the first driving assembly 20 to move upwards in the first direction, so that the material strip is offset toward the second end of the passing roller 10.
It should be noted that, the first end of the passing roller 10 may be selectively provided with a laser ranging sensor, or the first end of the passing roller 10 may be provided with a laser ranging sensor, or the first end and the second end of the passing roller 10 may be provided with a laser ranging sensor, and the first end and the second end of the passing roller 10 may be provided with a laser ranging sensor, so that erroneous detection of one of the laser detectors may be avoided, and the stability of the detected ground may be improved; the adoption of a single laser ranging sensor is beneficial to controlling the detection cost.
It should be noted that when pressure sensors are employed for the first detector 41 and/or the second detector 42, the overroller 10 may alternatively be provided in a floating arrangement or in a fixed arrangement relative to the pressure sensors. When the first detector 41 and/or the second detector 42 employ a laser ranging sensor, the over-roller 10 must be floatingly disposed with respect to the laser ranging sensor. The floating arrangement of the over-roller 10 relative to the first detector 41 and/or the second detection sensor is described in more detail below.
Referring to fig. 3, in one embodiment of the present invention, the apparatus for correcting deviation across the roller 10 further comprises: a first mounting plate 71; the roller 10 is disposed on the first mounting plate 71, the first mounting plate 71 is slidably engaged with the first and second driving assemblies 20 and 30 in the second direction, and the first mounting plate 71 is also rotatable about the third direction while being slid. The first detector 41 and/or the second detector 42 are provided on the first mounting plate 71.
By providing the first mounting plate 71, the first detector 41 and/or the second detector 42 and the roller 10 are conveniently arranged on the same plate, so that the deviation rectifying function and the deviation rectifying detection function are integrated, and the simplification of the deviation rectifying device of the roller 10 is facilitated. Moreover, the first detector 41 and/or the second detector 42 can be arranged perpendicular to the material belt surface, so that the first detector 41 and/or the second detector 42 can realize accurate material belt offset detection while moving along with the roller 10.
In one embodiment of the invention, the over-roller 10 is fixedly arranged on the first mounting plate 71, and the first detector 41 and/or the second detector 42 are fixedly arranged on the first mounting plate 71, in which case the first detector 41 and/or the second detector 42 employ a pressure sensor and are in contact with the first end of the over-roller 10 and/or the second end of the over-roller 10. The pressure sensor is capable of detecting a change in pressure applied to both ends of the over-roll 10 in a first direction, thereby detecting a deviation of the web on the over-roll 10 from the pressure change. In this embodiment, the positions of the over-roller 10 and the first detector 41 and/or the second detector 42 are relatively fixed, so that interference of external factors on the detection of the material belt offset by the first detector 41 and/or the second detector 42 can be effectively reduced, the accuracy of the material belt offset detection is ensured, and a good foundation is provided for deviation correction of the material belt.
In another embodiment of the present invention, the first detector 41 and/or the second detector 42 are fixedly disposed on the first mounting plate 71, the over roller 10 is floatingly disposed on the first mounting plate 71, and both ends of the over roller 10 can be relatively far from or near to the first detector 41 or the second detector 42 in the first direction. At this time, the first detector 41 and/or the second detector 42 may employ a pressure sensor or a laser ranging sensor.
If a pressure sensor is used for the first detector 41 and/or the second detector 42, the pressure sensor is kept at a certain transition distance from the end of the over roller 10. When the displacement of the end of the over roller 10 in the first direction is within this transition distance, the pressure sensor does not output a correction signal; when the displacement of the end of the over roller 10 in the first direction exceeds the transition distance, the end of the over roller 10 contacts with the pressure sensor, at this time, the pressure sensor outputs a deviation correcting signal outwards, and the deviation correcting control unit drives the first driving component 20 and/or the second driving component 30 to move over the first end and/or the second end of the roller 10 according to the deviation correcting signal, so as to correct the deviation of the material belt on the over roller 10.
By adopting the arrangement, the frequency of deviation correction can be reduced.
Further, the first mounting plate 71 may be optionally provided with a first adjusting seat 51 and/or a second adjusting seat 52, the first detector 41 is disposed on the first adjusting seat 51, and the second detector 42 is disposed on the second adjusting seat 52, so that the distance between the first detector 41 and the first end of the roller 10 is adjusted by the first adjusting seat 51, and the distance between the second detector 42 and the second end of the roller 10 is adjusted by the second adjusting seat 52, so as to realize adjustment of deviation rectifying detection precision.
Specifically, the larger the transition distance between the pressure sensor and the over roller 10 is, the larger the end part of the over roller 10 needs to be displaced in a moving way, namely the larger the swing of the over roller 10 is, the larger the swing of the over roller 10 can be sensed by the pressure sensor, and the deviation correcting precision is lower at the moment; on the contrary, the smaller the transition distance between the pressure sensor and the passing roller 10 is, the smaller the passing roller 10 swings to a small extent, so that the pressure sensor can sense the deviation, and the deviation rectifying accuracy is higher.
Illustratively, in the embodiment of the present invention, two single-axis precision sliding tables are provided as the first adjusting seat 51 and the second adjusting seat 52 on the first mounting plate 71, the two sliding tables being provided on the lower sides of both ends of the passing roller 10, respectively. The sliding table is provided with a 7-shaped first fixing plate 511 and a second fixing plate 521, and the vertical parts of the first fixing plate 511 and the second fixing plate 521 are fixed on the sliding table.
