Detailed Description

The technical solutions in the embodiments of the present invention will be described below in a clear and complete manner with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

The utility model provides an angle correction device for correcting and limiting a form position/orientation angle (hereinafter, referred to as a material position) of a material, and discloses a method for correcting the material angle by using the device. The purpose of material angle correction lies in: the materials leaving the station of the angle correcting device have uniform state when reaching the subsequent station, so that the materials can be directly subjected to subsequent processing, such as assembly, cleaning, bonding or lubricating. The utility model is not limited by the type of the material, nor is it limited by the subsequent processing of the material. The structural composition and principle of the angle correction device will be described below by taking the angle correction of the dialyzer container part as an example.

The angle correction device comprises a material carrying part 10 used for carrying and fixedly connecting with a container part of a dialyzer, and a main adjusting part 20 which can be detached from the material carrying part 10 to change the motion state of the material carrying part 10. Wherein, the loading part 10 has a preset reference center and has a degree of freedom of rotation with the reference center as a rotation center, and the degree of freedom is defined as a degree of freedom of adjustment movement; the main adjusting member 20 can be connected to the loading member 10, or can be separated from the loading member 10, and has various structural forms, and the main adjusting member is used for applying a driving force to the loading member 10 to change the movement state of the loading member 10 about the adjustment of the freedom degree of movement, and can drive the loading member 10 to start and rotate around a reference center, and can also drive the loading member 10 to decelerate and rotate around the reference center, that is, brake the loading member 10 in the rotation state around the reference center to make the loading member 10 tend to be stationary. The container portion is thus able to follow the rotation of the load member 10 and to synchronously change its own rotation state about the reference center; in addition, the angle correcting device further comprises a calibration member 30, wherein the calibration member 30 can move relative to the reference center and forms a rotation stop connection with the loading member 10 when the calibration member reaches a preset offset position so as to prevent the loading member 10 and the container part from continuously rotating synchronously and keep the loading member 10 in a state that the rotation of the loading member is completely stopped. Therefore, once the calibration member 30 and the material loading member 10 form the rotation-stopping connection, the completion of the angle correction of the container portion is marked, and the container portion reaches the position required by the subsequent process.

Example one

Referring to fig. 1 to 3, the main adjusting member 20 not only can provide a braking force for the rotation of the loading member 10, but also can drive the loading member 10 to rotate around a reference center; the material loading part 10 comprises a plurality of groups of material mounting elements 12 connected with a power output part of the main adjusting part 20, and can respectively and fixedly carry a plurality of groups of container parts, each group of material mounting elements 12 defines a material positioning central line orthogonal to the reference center, and when the container parts are fixedly carried by one group of material mounting elements 12, the axis of the container parts is superposed with the material positioning central line. In this embodiment, each group of material mounting elements 12 includes two material connecting portions arranged oppositely, the two material connecting portions are respectively used for fixedly connecting two ends of the container portion, a connecting line of the two material connecting portions is a material positioning central line, and a plurality of material positioning central lines of the plurality of groups of material mounting elements 12 are crossed in different planes. In other embodiments, the material mounting element 12 may also fix the load-bearing container portion by connecting the side walls of the container portion, for example, the material mounting element 12 is provided with a cylindrical surface adapted to the side walls of the container portion, and the axis of the cylindrical surface is the material positioning center line.

Further, the load carrier 10 also comprises an overflow preventing member 13 for accommodating the material mounting element 12 and the container part. The anti-overflow piece 13 is in a cylindrical shape, one end of the anti-overflow piece facing the main adjusting piece 20 is open for the material installation element 12 and the container part to enter, the end of the anti-overflow piece far away from the main adjusting piece 20 is closed, and the side wall of the cylindrical body is used for preventing the adhesive of the container part from splashing outwards in the high-speed rotation process. When the material angle correction operation is performed, the material mounting element 12 and the anti-overflow piece 13 can be fixedly connected into a whole so as to synchronously rotate, the reference center is the cylinder axis of the anti-overflow piece 13, and a plurality of container parts are distributed at intervals in the anti-overflow piece 13 along the cylinder axis of the anti-overflow piece 13. It should be noted that the overflow prevention element 13 is provided for the requirements of the dialyzer production process, because the container part needs to change its internal adhesive distribution by centrifugation at high speed rotation, so that it is necessary to provide the overflow prevention element 13 to prevent adhesive splashing, whereas the overflow prevention element 13 is not necessarily provided when other types of materials are to be corrected.

Referring to fig. 1 to 3 again, the angle correcting apparatus further includes a sensing unit 40 and a marking unit 50 connected to the loading member 10 in a following manner, the sensing unit 40 has a sensing triggering area with a specific spatial shape, and as long as the marking unit 50 moves past or at least partially lies within the sensing triggering area when following the rotation of the loading member 10, the sensing unit 40 can learn the movement past or in-place condition of the marking unit 50 and generate a position signal. The in-place signal can be used as a command to instruct the main adjusting member 20 to stop driving the carrier 10, or to instruct the main adjusting member to apply a braking force to the carrier 10 to stop the rotation of the carrier 10, and in any case, the main adjusting member 20 can respond to the in-place signal and cause the carrier 10 to tend to stop from rotating. In the first embodiment, the in-place signal is specifically used for indicating that the main adjusting member 20 stops driving the loading member 10 to rotate; the control system may also record the amount of rotational displacement of the carrier 10 below: the amount of displacement by which the carrier 10 has rotated is the period of time from when the marking unit 50 passes the sensing triggering area to when the carrier 10 has completely stopped rotating. For convenience of description, the displacement is defined as the redundant displacement of the carrier 10. Obviously, the above-mentioned issuing timing of the in-place signal may be the recording start timing of the redundancy shift amount. The calibration member 30 can be moved toward the predetermined offset position in response to the go-to-go signal and/or in response to the carriage 10 completely ceasing to rotate, however, whether the calibration member 30 will reach the predetermined offset position depends on the amount of redundant displacement, and the detailed principles and reasons will be explained below.

Specifically, the marking unit 50 is located outside the reference center, has a fixed circular motion track, and the sensing unit 40 can stop at a sensing position also located outside the reference center to wait for the marking unit 50 to move through or reach the induction triggering area. Therefore, the redundant displacement may be the length of the circular arc track rotated by the marking unit 50 from the time when the marking unit 50 passes through the sensing triggering area to the time when the marking unit 50 completely stops moving, or the central angle between the position of the marking unit 50 when the marking unit completely stops moving and the reference center line and the central angle between the sensing position and the reference center line.

The reasons for the redundant displacement include: 1) the main adjusting part 20 stops driving the loading part 10, lags behind the control system in time from receiving the in-place signal, and the main adjusting part 20 additionally drives the loading part 10 to rotate to form redundant displacement; 2) due to the high rotational speed of the carrier member 10, the carrier member 10 cannot immediately stop rotating under inertia.

In this embodiment, the marking unit 50 is connected to the bottom wall of the overflow preventing member 13 relatively far from the end of the main adjusting member 20, the sensing unit 40 is connected to the sensing pushing member 70 installed on the conveying line, and the sensing pushing member 70 preferably adopts a cylinder, which can push the sensing unit 40 to extend to move to the sensing position, and can also drive the sensing unit 40 to retract to exit the sensing position after the container portion angle correction is completed. The distance from the marking unit 50 to the reference center is consistent with the distance from the sensing position to the reference center, and the sensing unit 40 has an avoidance space, and when the sensing unit is pushed out by the sensing pushing member 70 and stops at the sensing position, the marking unit 50 can rotate along with the anti-overflow member 13 and pass through the avoidance space, which is the above-mentioned sensing triggering area. In other embodiments, the sensing unit 40 may also be fixedly disposed on the conveying line, and the sensing pusher 70 is omitted.

In some embodiments, the carrier 10 further comprises: at least two rotation stopping connecting pieces 11 which are fixed in relative positions and can be fixedly arranged relative to the material mounting element 12 in the material angle correcting process; the calibration member 30 includes the rotation stopping positioning surface 31, and the calibration member 30 can be close to the preset offset position and contact one of the rotation stopping connection members 11 through the rotation stopping positioning surface 31 first, and then outputs a driving force to the rotation stopping connection member 11, so as to drive the material mounting element 12 and the anti-overflow member 13 to rotate around the reference center together until the rotation stopping positioning surface 31 contacts the other rotation stopping connection member 11, at this time, the calibration member 30 is in the preset offset position, at least two rotation stopping connection members 11 are all abutted to the rotation stopping positioning surface 31, and the material carrying member 10 cannot continue to rotate. The driving force output from the calibration piece 30 to the rotation-stopping connection piece 11 has a component orthogonal to the reference center. For convenience of description, the driving force of the calibration piece 30 acting on the rotation-stopping connection piece 11 is hereinafter referred to as a posture correction torque.

In this embodiment, the rotation-stopping connecting member 11 is fixedly installed on the bottom wall of the overflow-preventing member 13, which is relatively far away from one end of the main adjusting member 20, and includes four positioning pins which are relatively fixedly arranged and four bearings which are respectively sleeved with the corresponding positioning pins one by one. The preset offset position is located outside the reference center, and the rotation stop positioning surface 31 moves close to the reference center while the calibration member 30 moves close to the preset offset position. The rotation stop positioning surface 31 is preferably provided as a flat surface, and the direction of movement of the calibration member 30 close to the preset bias position is perpendicular to the rotation stop positioning surface 31. Of course, the direction of the movement of the calibration member 30 near the predetermined offset position may form other angles with the rotation stop positioning surface 31.

Specifically, four rotation stopping connecting pieces 11 are uniformly arranged on the bottom wall of the anti-overflow piece 13 around the reference center. If the bottom wall of the overflow preventing member 13 is viewed in the extending direction of the reference center, when the aligning member 30 reaches the preset offset position, the line segment representing the rotation stop positioning surface 31 intersects the circle where the four rotation stop coupling members 11 are located. In the present embodiment, the calibration member 30 is translated near the reference center in the cylinder radial direction of the overflow prevention member 13. As mentioned above, whether the calibration member 30 is to be moved closer to the predetermined offset position depends on the amount of the redundant displacement.

Referring to fig. 4 to fig. 6, the relative position relationship between the rotation stop connecting element 11, the marking unit 50 and the sensing unit 40 shown in fig. 4 represents: the calibration member 30 being in the preset offset position is just in contact with two of the rotation stop connectors 11 simultaneously, the degree of freedom of the rotation of the loading member 10 around the reference center is limited, and the marking unit 50 is just in the induction triggering area of the sensing unit 40 being parked in the sensing position, which marks the completion of the material angle correction. Fig. 5 and fig. 6 show two possible results of the relative position relationship between the rotation stopping connection member 11, the marking unit 50 and the sensing unit 40 when the main adjustment member 20 drives the loading member 10 to rotate for the first time by an arbitrary angle and the loading member 10 stops rotating, the angle β in fig. 5 shows the central angle corresponding to the redundancy displacement at this time, and the angle α in fig. 6 shows the central angle corresponding to the redundancy displacement at this time.

In the situation shown in fig. 5, the calibration member 30 may continue to move to the preset offset position, and the rotation-stopping positioning surface 31 may first contact the shaded rotation-stopping connection member 11a, and then drive the loading member 10 to rotate counterclockwise by a certain angle until the rotation-stopping positioning surface 31 contacts the rotation-stopping connection member 11b, and finally the relative positional relationship between the rotation-stopping connection member 11, the marking unit 50 and the sensing unit 40 is switched to the state shown in fig. 4. It can be seen that, for the case shown in fig. 5, the calibration member 30 drives the material loading member 10 to rotate to the angular displacement correction amount corresponding to the case shown in fig. 4, which is exactly the angular displacement stroke corresponding to the redundant displacement amount, that is, the case shown in fig. 5 can directly offset the redundant displacement amount by the movement of the calibration member 30 close to the preset offset position.

In the situation shown in fig. 6, if the calibration member 30 continues to move to the preset offset position, the rotation-stopping positioning surface 31 first contacts the rotation-stopping connection member 11a marked with the shade, and then drives the material loading member 10 to rotate clockwise by a certain angle until the rotation-stopping positioning surface 31 contacts the rotation-stopping connection member 11c, and finally the relative position relationship among the rotation-stopping connection member 11, the marking unit 50 and the sensing unit 40 cannot be switched to the state shown in fig. 4. Therefore, for the case shown in fig. 6, the aligning member 30 does not move to the preset offset position immediately after the main adjusting member 20 stops driving the loading member 10. The control system records the magnitude of the redundant displacement shown in fig. 6 and calculates the angular displacement (for convenience of explanation, referred to as compensation angular displacement) required by the loading member 10 from the state shown in fig. 6 to the state shown in fig. 4, and instructs the main adjusting member 20 to drive the loading member 10 to rotate clockwise or counterclockwise for the second time, the main adjusting member 20 can drive the loading member 10 to rotate clockwise (2 pi- α) or drive the loading member 10 to rotate counterclockwise by α until the relative position relationship between the rotation-stopping connecting member 11, the marking unit 50 and the sensing unit 40 is switched to the state close to that shown in fig. 4 or fig. 5, because of system delay or inertia effect, the main adjusting member 20 drives the loading member 10 to rotate twice according to the compensation angular displacement and still cannot reach the state shown in fig. 4, so that the control system also needs to record a new redundant displacement, and determines whether the calibration member 30 moves to the preset offset position according to the new redundant displacement, if the new redundant displacement is large, the calibration member 30 still cannot move to the predetermined offset position, and the above steps need to be repeated again.

It should be noted that, in the present embodiment, four rotation-stopping connecting pieces 11 uniformly arranged around the reference center are only a preferred embodiment, and the number of rotation-stopping connecting pieces 11 is not limited to four, and does not need to be uniformly arranged around the reference center; the rotation stop positioning surface 31 is not necessarily provided as a flat surface. The rotation stopping connecting member 11 may be configured in other structures, and the bearing sleeve is selected to be provided with a positioning pin so as to reduce the wear generated by the multiple contact action of the calibration member 30 and the loading member 10, and improve the feedback sensitivity of the loading member 10 to the driving contact of the calibration member 30.

In other embodiments, a correction slope may be provided for the calibration member 30, and the correction slope abuts the rotation stop positioning surface 31. The calibration member 30 can move in a direction parallel to the rotation stop positioning surface 31 thereof with respect to the reference center, and can push the rotation stop connection member 11 through the correction slope side to output a posture correction torque to the carrier member 10. If the bottom wall of the overflow preventing member 13 is viewed in the extending direction of the reference center, the line segment representing the rotation stop positioning surface 31 is cut off from the circle on which the four rotation stop connecting members 11 are located, and the line segment representing the straightening slope is inclined with respect to the rotation stop positioning surface 31 toward the side of the rotation stop positioning surface 31 away from the reference center. During the movement of the calibration member 30 relative to the reference center, the correction slope first contacts one of the rotation stop connectors 11, and then drives the carrier member 10 to rotate until the rotation stop locating surface 31 contacts the other rotation stop connector 11.

In some embodiments, the calibration member 30 may include at least two rotation-stopping contact portions, the material-carrying member 10 includes a rotation-stopping matching portion, and the calibration member 30 can move close to the preset offset position, and contact the rotation-stopping matching portion through one of the rotation-stopping contact portions, and then drive the material-carrying member 10 to rotate around the reference center until the calibration member 30 reaches the preset offset position and contacts the other rotation-stopping contact portion, so as to form a rotation-stopping connection with the material-carrying member 10. The principle of operation of this embodiment is substantially the same as that of the embodiment represented in fig. 1 to 6.

In some embodiments, the structure of the rotation stopping connecting member 11 may also be different from the previous embodiments, where the rotation stopping connecting member 11 includes two force receiving portions that are fixed relatively and formed integrally or connected integrally, and the calibration member 30 can move close to the preset offset position and contact one of the force receiving portions first, and then drive the loading member 10 to rotate to the reference center until the calibration member 30 reaches the preset offset position, at which time the calibration member 30 keeps contact with both of the force receiving portions.

Further, the angle correcting apparatus further includes a braking member capable of responding to a position signal generated when the marking unit 50 passes through the sensing triggering area, and then being connected to the power output portion of the main adjusting member 20, or at least being connected to the carrier member 10 at a position other than the reference center, thereby providing a braking torque to the carrier member 10 opposite to the driving direction of the main adjusting member 20. And from the moment when the in-place signal is sent out to the moment when the loading part 10 stops rotating, the angular displacement of the loading part 10 in the period is the redundant displacement. It should be noted that the braking member can be carried by the main adjusting member 20 itself or can be independent of the main adjusting member 20. The significance of the brake member being connected to the power take-off of the main adjusting member 20 or the carrier member 10 outside the reference center is to provide as large a braking torque as possible, thereby reducing the amount of redundant displacement.

Further, the angle correcting apparatus further includes a clutch mechanism 60, and the clutch mechanism 60 can simultaneously connect the carrier member 10 and the main adjusting member 20 so that the main adjusting member 20 outputs a driving torque to the carrier member 10. Referring to fig. 1, the clutch mechanism 60 of the present embodiment includes a matching transmission assembly 61 and a pushing assembly 62, the matching transmission assembly 61 is connected to the driving end of the main adjusting member 20 in a following manner, and includes a wear-resistant member for directly abutting against the loading member 10, preferably a polyurethane ring, and the pushing assembly 62 can drive the matching transmission assembly 61 to abut against or separate from the loading member 10 along the extending direction of the reference center, and includes a telescopic element elastically deformed in the extending direction of the reference center. After the main adjusting part 20 drives the loading part 10 to rotate and stop for the first time, if the redundant displacement of the loading part 10 is small, the pushing mechanism drives the matching transmission component 61 to be separated from the loading part 10, so that the driving connection between the main adjusting part 20 and the loading part 10 is released, and the calibration part 30 can push the loading part 10 without obstruction; if the redundant displacement of the loading member 10 is large, the pushing mechanism keeps the state of connecting the main adjusting member 20 and the loading member 10, so that the main adjusting member 20 drives the loading member 10 to rotate for the second time.

Example two

Referring to fig. 7, unlike the first embodiment, the main function of the main adjusting member 20 of the second embodiment is to apply a braking torque to the loading member 10 so as to stop the rotation of the loading member 10 in a rotating state as soon as possible. The power source for driving the carrier member 10 to rotate can be generated by the main adjusting member 20 or can be provided by a driver independent from the main adjusting member 20. Thus, in the second embodiment, the main adjusting member 20 makes the carrier member 10 approach to the stationary state from the rotating state by suppressing the rotation of the carrier member 10. Similar to the embodiment, the angle correcting device further comprises a marking unit 50 which is connected with the loading member 10 in a follow-up mode, and a sensing unit 40 with a sensing triggering area, wherein the marking unit 50 passes through a sensing position which is located outside the reference center just along the rotating track of the loading member 10, and the sensing unit 40 can pause at the sensing position to wait for the marking unit 50 to pass through the sensing triggering area.

The angle correcting device also comprises a rotation stopping connecting part 14 which is arranged on the loading part 10 in a follow-up mode, and different from the first embodiment in which at least two rotation stopping connecting parts 11 are arranged, the number of the rotation stopping connecting parts 14 can be one as long as the rotation stopping connecting parts are positioned outside the reference center. The rotation stop connecting portion 14 follows the trajectory of the rotation of the carrier member 10 about the reference center, and also passes through the preset offset position. The operation of the angle correcting device according to the second embodiment will be described with reference to fig. 7, wherein the direction X indicates the rotation direction of the carriage 10, the rotation direction of the marking unit 50 attached to the carriage 10 and the rotation stopping connection portion 14 attached to the carriage 10, and the direction Y indicates the movement direction of the calibration member 30 to the predetermined offset position.

Firstly, the material loading part 10 is in a rotating state, the material loading part drives the marking unit 50 to pass through an induction triggering area of the sensing unit 40, the sensing unit 40 sends out a position signal when sensing that the marking unit 50 passes through, the main adjusting part 20 responds to the position signal and applies a braking torque to the material loading part 10, at the moment, the calibrating part 30 responds to the position signal and moves close to a preset offset position along a direction Y, and when the rotation stopping connecting part 14 is abutted to the calibrating part 30, the position state adjustment of the dialyzer container part is completed.

Optionally, the loading member 10 can rotate at an extremely fast initial speed, at this time, the driver driving the loading member 10 to rotate is already separated from the loading member 10, the loading member 10 rotates under the inertia effect and drives the marking unit 50 to pass through the sensing unit 40 for multiple times, the sensing unit 40 not only senses the passing of the marking unit 50, but also records the passing time of the marking unit 50, the speed change of the loading member 10 is determined according to the interval length of the multiple times when the marking unit 50 passes through the sensing triggering area, when the rotation speed of the loading member 10 is reduced below a certain threshold, the sensing unit 40 sends out a last in-place signal, the main adjusting member 20 responds to the in-place signal and brakes the loading member 10, and the calibration member 30 responds to the last in-place signal and moves to a preset offset position. The sensing unit 40 may employ an encoder to achieve the above functions.

A method for correcting the angle of a material using an angle adjusting device is described below, the method comprising the steps of:

s10, driving the loading part 10 to rotate by taking the reference center as a rotation center, so that the loading part 10 at least reaches a preset position state;

s20, by the preset position, the sensing unit 40 generates a position signal to instruct the main adjusting member 20 to prevent the loading member 10 from rotating around the reference center;

s30, stopping the rotation of the calibration member 30 by the in-place signal or the material carrying member 10, moving the calibration member 30 to the preset offset position and connecting the material carrying member 10 until the calibration member 30 reaches the preset offset position;

s40, the sensing unit 40 senses whether the marking unit 50 exists in the sensing triggering area, and when the marking unit 50 exists in the sensing triggering area, the angle correction of the material is completed.

Specifically, the preset bit states mentioned in step S10 represent: during the synchronous rotation of the marking unit 50 with the carrier 10, the carrier 10 is in the position at the moment when the marking unit 50 reaches the sensing position. The calibration piece 30 has been previously parked in the sensing position to await the marker unit 50 to reach and pass its sensing trigger zone. Therefore, although the material angle correction method does not specifically limit the specific angular displacement amount by which the main adjusting member 20 first drives the loading member 10 to rotate, the driving stroke should be large enough to cover the situation that the loading member 10 is in the preset position.

The rotation of the loading member 10 can be driven by the main adjusting member 20, or by an external driver to drive the loading member 10. If an external drive is used to drive the carrier 10 to rotate, as in the case of the second embodiment, the main adjusting member 20 is specifically configured to apply a braking torque to the carrier 10 to bring the carrier 10 to a stop from rotating as quickly as possible. Thus, for the above first embodiment, step S10 includes: s11, the main adjusting member 20 drives the loading member 10 to rotate around the reference center as the rotation center, so that the loading member 10 at least reaches the preset position.

Further, in one embodiment, step S30 includes:

s31, acquiring the relative position difference between the marking unit 50 and the sensing unit 40 when the loading piece 10 is in a static state;

s32, comparing the relative position difference with a preset reference position difference, and when the relative position difference is smaller than the reference position difference, indicating the calibration piece 30 to move to a preset offset position and driving the loading piece 10 to rotate until the calibration piece 30 reaches the preset offset position; when the relative position difference is greater than or equal to the reference position difference, the carrier 10 is driven to rotate again, and the steps S10 to S30 are repeated.

The in-place signal may be a condition for triggering step S20, the timing of issuance of which is also the initial timing for recording the amount of redundancy displacement. From the sending of the in-position signal to the time when the carrier 10 stops rotating and reaches the stationary state, the angular displacement of the carrier 10 is the redundant displacement, that is, the relative position difference between the marking unit 50 and the sensing unit 40 at the sensing position in step S31, at this time, the relative position difference represents the included angle between the connecting line from the marking unit 50 to the reference center and the connecting line from the sensing position to the reference center.

As for step S32, as mentioned above, whether the calibration piece 30 is to be moved to the preset bias position depends on the magnitude of the redundant displacement amount, i.e., the relative position difference between the marking unit 50 and the sensing unit 40 at the sensing position. The reference position difference is a preset judgment reference, and when the redundant displacement is greater than the reference position difference, the system controls the calibration member 30 to move to a preset offset position, so that the container part can reach the required position only by being driven by the main adjusting member 20 and the calibration member 30 once respectively. Otherwise, the main adjusting member 20 needs to drive the loading member 10 to rotate for the second time, that is, in step S32, when the relative position difference is greater than or equal to the reference position difference, the loading member 10 is driven to rotate again, and steps S10 to S30 are repeated, so as to make the loading member 10 reach the preset position state again and reduce the redundant displacement amount after the second rotation as much as possible. Generally, the angle correction of the container portion can be completed by the carrier 10 through at most two drives of the main adjusting member 20 and one drive of the calibration member 30, but there is a very low possibility that the carrier 10 needs to be driven three or more times by the main adjusting member 20 and additionally the angle correction can be completed by one drive of the calibration member 30. If the servo motor is selected as the main adjusting member 20, the possibility that the redundant displacement amount is larger than the reference position difference is significantly reduced, and there is no need to drive the carrier member 10 to rotate again, and the steps S10 to S30 are repeated.

Further, in step S40, when the marking unit 50 is not located in the sensing triggering area, the calibration member 30 is instructed to drive the carriage 10 to rotate until the marking unit 50 is located in the sensing triggering area. Specifically, step S40 further includes the steps of: and S41, acquiring the relative position difference between the marking unit 50 and the sensing unit 40 again, and finishing the material angle correction when the relative position difference is smaller than or equal to the preset critical deviation.

For step S41, the predetermined critical deviation provides an allowable error interval for the container angle correction, that is, after the calibration member 30 drives the loading member 10 to rotate, the relative position difference between the marking unit 50 and the sensing unit 40 at the sensing position does not exceed the predetermined critical deviation, and it is determined that the position of the container reaches the desired final position.

Further, in step S41, when the relative position difference is greater than the preset threshold deviation, the calibration member 30 is instructed to drive the carrier member 10 to rotate again until the relative position difference is smaller than the preset threshold deviation, and it should be noted that the calibration member 30 used for driving the carrier member 10 to rotate here may be the calibration member 30 that drives the carrier member 10 in step S30, or may be another independent calibration member 30. For example, two opposite calibration members 30 may be provided at the container portion angle correction station, and each of the two calibration members has a rotation stop positioning surface 31 disposed opposite to each other, and can be used to drive the carrier member 10 to rotate in a clockwise direction or a counterclockwise direction to eliminate an error amount of which the relative position difference is larger than a preset critical deviation.
