All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In this application, the terms "mounted," "disposed," "provided," "connected," and "connected" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In addition, the terms "first," "second," etc. are used primarily to distinguish between different devices, elements, or components (the particular species and configurations may be the same or different), and are not used to indicate or imply the relative importance and number of indicated devices, elements, or components. Unless otherwise indicated, the meaning of "a plurality" is two or more.

The technical scheme of the present application will be further described with reference to specific embodiments and drawings.

Referring to fig. 1 and fig. 2 together, the embodiment of the present application discloses a conveying device 1, which includes a conveying mechanism 11 and a deviation correcting mechanism 12. The conveying mechanism 11 includes a frame 111, a conveying driving assembly 112, and a belt 113, the conveying driving assembly 112 is disposed on the frame 111, the belt 113 is sleeved on the conveying driving assembly 112, the belt 113 is used for carrying a workpiece to be conveyed, and the conveying driving assembly 112 is used for driving the belt 113 to rotate so as to convey the workpiece to be conveyed along a first direction 131. The deviation rectifying mechanism 12 comprises a deviation rectifying swing roller 121 and a deviation rectifying driving assembly 122, the deviation rectifying swing roller 121 comprises a first end 1211 and a second end 1212 which are opposite, the first end 1211 is movably arranged on the frame body 111, the second end 1212 is connected with the deviation rectifying driving assembly 122, the belt 113 is further sleeved on the deviation rectifying swing roller 121, and when the deviation of the belt 113 exceeds a preset deviation, the deviation rectifying driving assembly 122 is used for driving the second end 1212 to rotate relative to the frame body 111 so as to adjust the deviation of the belt 113 to be within the preset deviation.

It will be appreciated that the belt 113, when being sleeved on the conveying driving assembly 112, may be divided into a working section for conveying the workpiece to be conveyed, i.e., the working section for conveying the workpiece to be conveyed at the initial position to the destination, and a return section for returning from the destination to the initial position to re-convey the workpiece to be conveyed. While the first direction 131 is the conveying direction of the belt 113, i.e. the length direction of the working section.

Since the belt 113 inevitably vibrates during transportation, the belt 113 may move relatively to the conveyor drive assembly 112 during vibration, so that the belt 113 may be offset in the width direction. When the shift amount of the belt 113 in the width direction is small, the accuracy of the transportation of the belt 113 is not affected, or the influence is so small as to be negligible, so that the preset shift amount may be set as a reference, and when the shift amount of the belt 113 in the width direction is within the preset shift amount, the belt 113 may be considered to be in a normal operation state. However, when the belt 113 excessively shifts in the width direction, that is, when the shift amount of the belt 113 in the width direction is excessively large, the belt 113 cannot accurately convey the member to be conveyed to the destination, thereby affecting the execution of the subsequent process, and at this time, the belt 113 may be considered to be in an abnormal operation state.

Therefore, the belt 113 is sleeved on the deviation rectifying swing roller 121, when the deviation of the belt 113 is too large, that is, when the deviation of the belt 113 exceeds the preset deviation, the deviation rectifying swing roller 121 is adjusted to achieve the purpose of adjusting the belt 113, that is, the deviation of the belt 113 is adjusted through adjusting the deviation rectifying swing roller 121, so that the deviation of the belt 113 is adjusted to be within the preset deviation. Specifically, the first end 1211 of the deviation rectifying swing roller 121 is movably connected to the frame 111, and the position of the deviation rectifying swing roller 121 relative to the frame 111 is changed by adjusting the position of the second end 1212, so as to change the relative positions of the belt 113 and the deviation rectifying swing roller 121, thereby achieving the purpose of adjusting the belt 113.

It will be appreciated that the belt 113 may have an optimal position during transportation, and the optimal position may be regarded as a position where the belt 113 is not offset, and the accuracy of transporting the article to be transported to the destination is highest when the belt 113 transports the article to be transported at the optimal position. Therefore, as the amount of deviation of the belt 113 is smaller, the accuracy of the belt 113 during transportation is higher. The preset offset may be regarded as a position where the belt 113 reaches a qualified position where the belt 113 can perform a transportation function, that is, when the offset of the belt 113 reaches a boundary of a range of the preset offset, the belt 113 is in a state where transportation is possible but the transportation accuracy is lowest.

With continued reference to fig. 1 and 2, in some embodiments, the deviation correcting driving assembly 122 is configured to drive the second end 1212 to rotate along the first direction 131 relative to the frame 111, so as to adjust the deviation of the belt 113 within a predetermined deviation.

The second end 1212 is driven by the deviation correcting driving assembly 122 to rotate along the first direction 131 relative to the frame 111, so that the deviation of the belt 113 can be adjusted, the belt 113 can be prevented from being deviated relative to the horizontal direction to make the belt 113 unstable during operation, and meanwhile, uneven tension of the belt 113 can be prevented from aggravating abrasion of the belt 113.

In other embodiments, the deviation correcting driving assembly 122 may also drive the second end 1212 to rotate relative to the frame 111 in a direction perpendicular to the first direction 131 and the width direction of the belt 113.

Referring to fig. 2 and fig. 3 together, in some embodiments, the deviation rectifying mechanism 12 further includes a swing roller slider 123, the swing roller slider 123 is disposed on the frame 111, the swing roller slider 123 is provided with a sliding groove 1231 extending along the first direction 131, the second end 1212 is disposed through the sliding groove 1231, and the deviation rectifying driving assembly 122 is configured to drive the second end 1212 to rotate in the sliding groove 1231 relative to the frame 111.

Wherein the width of the runner 1231 matches the diameter of the second end 1212 to limit displacement of the slider in a direction perpendicular to both the first direction 131 and the width of the belt 113, i.e., to limit movement of the second end 1212 only in the direction of extension of the runner 1231, thereby limiting rotation of the second end 1212 relative to the frame 111 only in the first direction 131. At the same time, to avoid the greater friction between the second end 1212 and the runner 1231 as it moves, the width of the runner 1231 may be slightly greater than the diameter of the pendulum roller, thereby reducing the amount of force that needs to be applied to move the second end 1212.

For example, the swing roller slider 123 may be disposed near the second end 1212 and face a surface opposite to the first end 1211 of the frame 111, where the frame 111 may also be provided with a through slot similar to the chute 1231, the second end 1212 sequentially penetrates the through slot and the chute 1231 and may protrude from the chute 1231, and the deviation correcting driving assembly 122 drives a portion of the second end 1212 protruding from the chute 1231. Of course, the swing roller slider 123 may be provided at other positions of the frame 111, which is not limited herein.

In other embodiments, the chute 1231 may also be provided on the frame 111.

Referring to fig. 3, in some embodiments, the deviation rectifying mechanism 12 further includes a limiting member 124, where the limiting member 124 is disposed on the swing roller slider 123 and is used to limit the angular range of rotation of the second end 1212 relative to the frame 111.

When the deviation correcting driving assembly 122 drives the second end 1212 to move along the sliding groove 1231, the problem of excessive movement of the second end 1212 is easy to occur without other limiting means, so that the second end 1212 needs to be driven to move in the opposite direction, and the maintenance time is prolonged. By providing the stopper 124, the angular range of the second end 1212 with respect to the frame 111 can be limited, that is, the range of the path along which the second end 1212 moves in the extending direction of the chute 1231 can be limited. When the second end 1212 moves to abut against the limiting member 124, it means that the second end 1212 has moved to the limit range, and the offset of the belt 113 is within the preset offset, and if the second end 1212 moves further, the offset of the belt 113 exceeds the preset offset, so that the adjustment is excessive.

In other embodiments, the limiting member 124 may also be disposed on the frame 111.

In some more specific embodiments, the limiting member 124 is disposed on the swing roller slider 123, at least a portion of the limiting member 124 is disposed in the sliding groove 1231, and a portion of the limiting member 124 disposed in the sliding groove 1231 can selectively reciprocate along the first direction 131, and the portion of the limiting member 124 disposed in the sliding groove 1231 is used to limit the angular range of rotation of the second end 1212 relative to the frame 111.

It will be appreciated that after the second end 1212 moves once, the relative position between the belt 113 and the deviation rectifying roller 121 may change when the belt 113 is at the optimal position during transportation, and if the position of the limiting member 124 relative to the sliding groove 1231 remains unchanged, the offset of the belt 113 exceeds the preset offset when the second end 1212 moves next and abuts against the limiting member 124. In order to avoid the above situation, after the second end 1212 moves once, the relative position between the limiting member 124 and the sliding slot 1231 needs to be changed correspondingly, that is, the position of the limiting member 124 needs to be adjusted, so that the offset of the belt 113 is adjusted to be within the preset offset after the second end 1212 moves next time and abuts against the limiting member 124.

In addition, since the smaller the offset of the belt 113, the higher the transportation accuracy of the belt 113, the position of the stopper 124 can be adjusted so that the second end 1212, when moving and abutting against the stopper 124, can bring the offset of the belt 113 within the preset offset, close to the non-offset position, thereby improving the transportation accuracy.

In other embodiments, the portion of the limiting member 124 located in the sliding groove 1231 can also rotate relative to the swing roller block 123 to adjust the range of movement of the second end 1212 within the sliding groove 1231.

Referring to fig. 4, in some embodiments, a deviation correcting shaft 1111 is disposed on the frame 111, and a first end 1211 is rotatably connected to the deviation correcting shaft 1111 and is rotatable about an axial direction of the deviation correcting shaft 1111, so that a second end 1212 is rotatable relative to the frame 111.

In order to enable the second end 1212 to rotate relative to the frame 111 along the first direction 131, the axial direction of the deviation correcting rotating shaft 1111 may be perpendicular to the first direction 131 and the width direction of the belt 113, and when the deviation correcting driving assembly 122 applies a force to the second end 1212 along the first direction 131, the first end 1211 rotates about the axial direction of the deviation correcting rotating shaft 1111, so as to achieve the purpose of rotating the second end 1212 relative to the frame 111 along the first direction 131.

In other embodiments, first end 1211 may be rotatably coupled to frame 111.

Referring to fig. 1 and 2 again, in some embodiments, the deviation correcting driving assembly 122 includes a cylinder 1221 and a floating joint 1222, the floating joint 1222 is connected between the cylinder 1221 and the second end 1212, and the cylinder 1221 drives the floating joint 1222 to rotate the second end 1212 relative to the frame 111 to adjust the deviation of the belt 113 within a predetermined deviation.

Notably, the second end 1212 moves when the output force of the cylinder 1221 is not equal to the tension of the belt 113.

For example, the cylinder 1221 may be disposed in a second direction 132 of the second end 1212, wherein the second direction 132 is opposite the first direction 131. When the output force of the air cylinder 1221 is equal to the tension of the belt 113, the second end 1212 remains stationary, i.e., the second end 1212 remains in place; when the output force of the air cylinder 1221 is greater than the tension of the belt 113, the second end 1212 moves in the first direction 131; when the output force of the air cylinder 1221 is less than the tension of the belt 113, the second end 1212 moves in the second direction 132.

In addition, since the cylinder 1221 may vibrate somewhat during operation, the floating joint 1222 coupled to the cylinder 1221 may dampen vibrations of the cylinder 1221, thereby reducing the effects of vibrations of the cylinder 1221 on the second end 1212.

In other embodiments, the disclosure-correcting drive assembly 122 may include a telescoping member coupled to the second end 1212, wherein the telescoping member moves the second end 1212 when telescoping.

With continued reference to fig. 1 and 2, in some embodiments, the offset actuator assembly 122 further includes a proportional valve control assembly 1223, the proportional valve control assembly 1223 being coupled to the cylinder 1221 and configured to adjust the driving force applied by the cylinder 1221 to the second end 1212 to rotate the second end 1212 relative to the frame 111.

The proportional valve control component 1223 is provided to increase or decrease the force output by the cylinder 1221, so that the effect of regulating the magnitude of the driving force applied to the second end 1212 can be achieved by adjusting the proportional valve control component 1223 without changing the force actually output by the cylinder 1221.

Illustratively, the air cylinder 1221 is disposed in the second direction 132 of the second end 1212, wherein the second direction 132 is opposite the first direction 131, and the force output by the air cylinder 1221 may be equal to the tension of the belt 113 and remain the same; when it is desired to move the second end 1212 in the first direction 131, the force output by the cylinder 1221 is increased when applied to the second end 1212 by adjusting the proportional valve control assembly 1223, i.e., such that the driving force applied to the second end 1212 is greater than the tension of the belt 113, thereby causing the second end 1212 to move in the first direction 131; when it is desired to move the second end 1212 in the second direction 132, the force output by the cylinder 1221 is reduced when applied to the second end 1212 by adjusting the proportional valve control assembly 1223 such that the driving force applied to the second end 1212 is less than the tension of the belt 113, thereby causing the second end 1212 to move in the second direction 132.

In other embodiments, the amount of driving force applied to the second end 1212 by the cylinder 1221 may also be controlled by directly adjusting the force output by the cylinder 1221.

With continued reference to fig. 1 and 2, in some embodiments, the deviation correcting mechanism 12 further includes a deviation detecting component 125, where the deviation detecting component 125 is configured to detect an offset of the belt 113.

It will be appreciated that the deviation detecting component 125 may determine whether the deviation of the belt 113 exceeds the preset deviation by detecting whether the position of the belt 113 in the width direction exceeds the position corresponding to the boundary of the range of the preset deviation, if it is determined that the deviation of the belt 113 exceeds the preset deviation, the deviation correcting driving component 122 drives the second end 1212 to move, thereby adjusting the position of the belt 113, and if it is determined that the deviation of the belt 113 does not exceed the preset deviation, the second end 1212 may be kept stationary.

In other embodiments, the deviation detecting assembly 125 may also detect the position of the belt 113 at any moment in the width direction, so as to obtain an accurate deviation of the belt 113.

Of course, in other embodiments, the amount of belt 113 offset may be determined approximately by manual observation, and by manual determination of whether it is necessary to control the deviation correcting drive assembly 122 to move the second end 1212.

Referring to fig. 2 and 5, in some embodiments, the deviation detecting assembly 125 includes a first limit sensor 1251 and a second limit sensor 1252. The first limit sensor 1251 is configured to detect a first excessive deviation of the belt 113 in a positive direction of the width direction, and determine a first deviation of the belt 113 according to the first excessive deviation, and the deviation correcting driving assembly 122 is configured to drive the second end 1212 to rotate along the first direction 131 relative to the frame 111 according to the first deviation, so as to adjust the first deviation of the belt 113 within a preset deviation; the second limit sensor 1252 is configured to detect a second excessive deflection of the belt 113 in a direction opposite to the width direction, and determine a second deflection of the belt 113 according to the second excessive deflection, and the deviation correcting driving assembly 122 is configured to drive the second end 1212 to rotate in a second direction 132 opposite to the first direction 131 relative to the frame 111 according to the second deflection, so as to adjust the second deflection of the belt 113 within a preset deflection.

The first limit sensor 1251 is located in a forward direction of the second limit sensor 1252 in the width direction of the belt 113, and when the belt 113 is in the undeflected position, the first limit sensor 1251 is in a state in which the belt 113 is detected, and the second limit sensor 1252 is in a state in which the belt 113 is not detected.

It is to be understood that the belt 113 may be offset not only in the forward direction but also in the reverse direction in the width direction, and thus the first limit sensor 1251 and the second limit sensor 1252 are provided corresponding to detecting the amounts of offset of the belt 113 in both the forward and reverse directions in the width direction.

The first excessive offset detected by the first limit sensor 1251 and the second excessive offset detected by the second limit sensor 1252 form two boundary values of the preset offset, that is, the offset range between the first excessive offset and the second excessive offset is the preset offset.

Illustratively, when the first limit sensor 1251 is in a state in which the belt 113 is not detected, it indicates that the belt 113 is excessively shifted in the forward direction in the width direction, that is, the first shift amount of the belt 113 exceeds the first excessive shift amount, that is, the first shift amount of the belt 113 exceeds the preset shift amount, at which time the deviation correcting driving assembly 122 drives the second end 1212 to move in the first direction 131 so that the belt 113 is moved in the reverse direction in the width direction, and when the first limit sensor 1251 is again in a state in which the belt 113 is detected, it indicates that the first shift amount of the belt 113 is smaller than the first excessive shift amount, that is, the first shift amount of the belt 113 is within the preset shift amount.

Similarly, when the second limit sensor 1252 is in the state of detecting the belt 113, it indicates that the belt 113 is excessively shifted in the opposite direction of the width direction, that is, the second shift amount of the belt 113 is equal to or exceeds the second excessive shift amount, that is, the second shift amount of the belt 113 is equal to or exceeds the preset shift amount, at this time, the deviation correcting driving assembly 122 drives the second end 1212 to move in the second direction 132 opposite to the first direction 131, so that the belt 113 is moved in the positive direction of the width direction, and when the second limit sensor 1252 is again in the state of not detecting the belt 113, it indicates that the second shift amount of the belt 113 is smaller than the second excessive shift amount, that is, the second shift amount of the belt 113 is within the preset shift amount.

In other embodiments, the deviation detecting component 125 may also be provided with a first baffle and a second baffle on two sides of the belt 113 in the width direction, when the belt 113 contacts with the first baffle or the second baffle, the deviation detecting component 122 is controlled to drive the second end 1212 to move so as to adjust the deviation of the belt 113 within the preset deviation.

With continued reference to fig. 2 and 5, in some specific embodiments, the deviation detecting assembly further includes a deviation detecting origin sensor 1253, where the deviation detecting origin sensor 1253 is configured to detect a normal deviation of the belt 113 in a forward and reverse direction of the width direction, and the normal deviation is within a preset deviation.

It will be appreciated that when the belt 113 is moved from the undeflected position to the position where the offset is excessive, even if the second end 1212 is moved to adjust the position of the belt 113, the belt 113 is difficult to reach the same position after adjustment as when undeflected, that is, the position of the belt 113 after adjustment is intended to coincide with the position when undeflected, which is too difficult to occur even during actual debugging. If the position where the belt 113 is theoretically not offset is regarded as the optimal position of the belt 113, the belt 113 is not substantially at the optimal position after adjustment. The position of the belt 113 after the deviation is compared with the position of the belt 113 when the deviation is not caused, and if the deviation is small, the transportation accuracy of the belt 113 is not changed greatly, and the position of the belt 113 after the deviation can be regarded as the optimal position.

Therefore, the belt 113 may have a normal offset when it is in the optimal position, and when the offset of the belt 113 is within the normal offset, the transportation accuracy of the belt 113 does not change greatly, and the belt 113 may be regarded as approximately unbiased. In the adjustment process of the belt 113, the belt 113 in the excessively offset state is adjusted until the offset amount is within the normal offset amount, that is, the adjustment of the belt 113 is completed. It should be noted that the range of the normal offset is within the range of the preset offset, that is, the boundary value of the normal offset is smaller than the boundary value of the preset offset. In addition, the correction origin sensor 1253 is disposed between the first limit sensor 1251 and the second limit sensor 1252, so as to ensure that the normal offset range is within the preset offset range.

Illustratively, the deviation correcting origin sensor 1253 includes a first detection point and a second detection point, and the first detection point is located in a positive direction of the second detection point along the width direction of the belt 113, in other words, the first detection point is closer to the first limit sensor 1251 than the second detection point.

When the first limit sensor 1251 and the first detection point are in a state where the belt 113 can be detected and the second detection point and the second limit sensor 1252 are in a state where the belt 113 is not detected, the shift amount of the belt 113 is within the normal shift amount, and at this time, the belt 113 is in the optimum position, that is, the belt 113 can be regarded as being in the unbiased position.

When the first limit sensor 1251 is in a state in which the belt 113 is detected, the first detection point, the second detection point, and the second limit sensor 1252 are all in a state in which the belt 113 is not detected, the belt 113 is shifted in the positive direction in the width direction of the belt 113, and the shift amount of the belt 113 exceeds the normal shift amount but is still within the preset shift amount, and at this time, the belt 113 is not in the optimum position but is not in an excessively shifted state.

When the first limit sensor 1251, the first detection point, and the second detection point are in a state in which the belt 113 is detected, and the second limit sensor 1252 is in a state in which the belt 113 is not detected, the belt 113 is shifted in the opposite direction to the width direction of the belt 113, and the shift amount of the belt 113 exceeds the normal shift amount, but is still within the preset shift amount, and at this time, the belt 113 is not in the optimal position, but is not in an excessively shifted state.

In other embodiments, a reference line may be provided, and adjusting the belt 113 to approximately fit the reference line to the edge of the belt 113 during the adjustment of the belt 113 may be regarded as adjusting the belt 113 to an optimal position.
