Embodiments of the present disclosure provide a posture adjustment structure including: the base body extends along the X direction and is provided with a bearing surface, and the bearing surface is suitable for placing a tested object; the first adjustment subassembly sets up in the base member below, and wherein, first adjustment subassembly includes: the rack can slide in the X direction relative to the base body; the deflector rod is rotatably arranged on the stand by taking the Y shaft as a rotation axis; the poking head is arranged on the poking rod and can be abutted against the measured object under the driving of the poking rod so as to drive the measured object to deviate around the Y direction on the bearing surface and/or drive the measured object to move along the X direction on the bearing surface.

The gesture adjustment structure of the present disclosure can be used to adjust the motion gesture of a conveyed object on a production line; the device can also be used in the field of radiation detection and used for adjusting the detected object to a preset detection position. When applied in the field of radiation detection, there are at least the following scenarios in which the use of the attitude adjustment structure in the present disclosure is required, the scenarios are described below:

It can be appreciated that in the field of radiation detection, radiation imaging techniques can image the damage condition inside an object, facilitating the judgment of a inspector. In the detected object, the detection size of the region to be detected is small, for example, in the detection process of the lithium battery, it is necessary to detect the thin film or the glue layer of the lithium battery, but the thickness of the thin film or the glue layer of the lithium battery is small, and as shown in fig. 1, a black region denoted by 41 in the drawing is the thin film or the glue layer, an axis parallel to the main beam surface 61 is defined as a Z axis, and an axis parallel to the advancing direction of the object 4 is defined as an X axis. The Y axis is defined to be perpendicular to both the X axis and the Z axis. Wherein the imaging area 62 of radiation emitted by the light engine 6 is approximately conical. In actual detection, the inventor finds that when the detected layer (the detection surface parallel to the main beam surface) of the film or the adhesive layer deviates in the Z direction or the Y direction, the detected layer is influenced by the shape of the imaging region, and when the detected layer deviates from the imaging region, part of the detected layer cannot be detected, so that the problem of detection misalignment exists.

Based on the above-described problems, as shown in fig. 2 to 13, and fig. 15 and 16, a specific implementation of the posture adjustment structure in the embodiment of the present disclosure is shown.

Referring to fig. 3, the posture adjustment structure in the embodiment of the present disclosure includes a base 1, a first adjustment assembly 2, and a second adjustment assembly 3. Wherein, the object 4 is placed on the base 1, and the first adjusting component 2 is used for adjusting the object 4 to deviate on the base 1 around the Y direction, i.e. the direction indicated by the double-headed arrow in fig. 3.

Referring to fig. 4, the base body 1 in the embodiment of the present disclosure is arranged to extend in the X direction. A plurality of objects 4 may be placed on the base 1 at intervals. The substrate 1 may be a common production line, such as a production station, a placement line, etc.

Referring to fig. 10, the base 1 is designed as a line-type support frame, which includes two oppositely disposed frame bodies 12, and the first adjusting assembly 2 is disposed between the two frame bodies 12. The two frame bodies 12 are L-shaped in cross section, so that the two frame bodies comprise a horizontal supporting arm and a vertical supporting arm, the supporting rail 13 is arranged on the horizontal supporting arm, the upper surface of the supporting rail 13 is configured to be the bearing surface 11, the object 4 to be measured spans the two supporting rails 13 and is supported by the bearing surface 11 of the supporting rail 13, and the function of placing the object 4 to be measured is realized.

The object 4 in the embodiment of the disclosure may be a lithium battery, and when the lithium battery is placed on the carrying surface 11, it is required to basically ensure that a plane where the thickness of the glue layer or the film layer is located is set towards the optical machine of the imaging system.

Fig. 4 to 10 show a specific structure of the first adjusting assembly 2.

Referring to fig. 10, the first adjusting assembly 2 includes a frame 21, and the frame 21 is movably disposed on the base 1 and is slidable relative to the base 1. As shown in fig. 10, the frame 21 is a square frame structure, two oppositely disposed frame sides of which are respectively provided with a slide block 51, a slide rail 52 is mounted on an inner side surface of a vertical wall of the frame body 12 of the base 1, the slide block 51 is slidably disposed on the slide rail 52, and the movement of the frame 21 in the X direction relative to the base 1 is realized under the drive of an external force.

It will be appreciated that in some embodiments, the slider 52 may also be mounted to the frame 21, with the slide rail 51 being mounted to the base 1.

It is understood that the external force may be driven by human force, and may be electrically driven, hydraulically driven, pneumatically driven, etc.

The first adjustment assembly 2 in the embodiments of the present disclosure further comprises a rotating member. The rotating member is rotatably disposed on the frame 21 with the Y axis as a rotation axis, and is driven by an external force to drive the object to be measured to deviate around the Y direction on the bearing surface, and the rotating member is driven by the frame 21 to drive the object to be measured to move along the X direction.

It can be understood that there may be various structural forms of the rotating member, and the rotating member in the embodiment of the present disclosure adopts a form of combining a shift lever and a shift head, and the specific structure is as follows:

referring to fig. 5, a lever 22 is mounted on the chassis 21, and the lever 22 is rotatably provided on the chassis 21 with the Y axis as a rotation axis. Referring to fig. 9, a rotation shaft 211 is provided in the Y direction on the frame 21, and the rotation shaft 211 is fixed to the frame 21. Further, the frame 21 has a frame horizontally arranged between the frame bodies 12, the rotating shaft 211 is arranged at the center of the upper end face of the frame, and the arrangement at the center can ensure that the length of the rotating arm of the deflector 22 arranged on the rotating shaft 211 is kept consistent, so that the adjustment of the subsequent offset angle is convenient.

It will be appreciated that in order to rotatably mount the lever 22 on the shaft 211, in the embodiment of the present disclosure, the lever 22 is disposed on the adapter block 25, and the two levers 22 are disposed on the adapter block 25 opposite to each other, respectively. The middle position of the adapter block 25 is provided with a mounting hole, and a bearing and a retainer ring 27 for limiting the bearing from falling out of the mounting hole are embedded in the mounting hole. The rotating shaft 211 is cooperatively arranged in the bearing, so that the rotation of the rotating block 25 around the rotating shaft 211 is realized, and the deflector 22 is driven to rotate around the Y direction.

Referring to fig. 4, the first adjusting assembly 2 in the embodiment of the disclosure further includes a shift head 23, where the shift head 23 is disposed on the shift lever 22, and the shift head 23 can abut against the measured object 4 to drive the measured object 4 to shift around the Y direction on the bearing surface 11 and drive the measured object to move along the X direction on the bearing surface under the driving of the shift lever 22.

In the embodiment of the disclosure, the ends of the two shift levers 22 are respectively provided with a shift head 23, the shift heads 23 protrude from the bearing surface 11, and can be abutted against the end surface of the measured object 4 facing away from the moving direction when the stand 21 moves, and in order to realize deflection of the measured object 4, the abutting position of the shift heads 23 deviates from the center position of the end surface.

It can be understood that the process of the shift head 23 driving the measured object 4 to shift around the Y direction on the bearing surface 11 is as follows, when the rack 21 is driven to move to the measured object 4 by an external force, if the measured object is detected to shift around the Y direction, the adapter 25 rotates to drive the shift lever 22 to rotate, so that the shift head 23 on the shift lever 22 acts on the measured object 4, and the shift head 23 pushes the measured object 4 to rotate, thereby correcting the shift of the measured object 4. The detection mode of whether the detected object 4 deviates in the Y direction can detect the space position coordinate of the current detected object 4 through a position sensor so as to judge whether the detected object 4 deviates; the determination may also be performed by the detection result of the previous object 4, and if the detection result of the previous object 4 is that the offset occurs, the offset adjustment needs to be performed on the current object 4.

It will be appreciated that after the offset correction of the object 4 is completed, when the frame 21 continues to move along the X direction, the shift head 23 can push the object 4 to move along the X direction, and then the next detection step is performed.

It will be appreciated that in some embodiments, the shift head 23 may only abut against the object 4 under the driving of the shift lever 22 to drive the object 4 to shift on the bearing surface 11 around the Y direction. The movement of the object 4 to be measured in the X direction may be driven by other structures.

It will be appreciated that in some embodiments, the rotating member may also be a combination of a turntable and a lifting structure. Specifically, the turntable is arranged on the lifting structure, the turntable 21 can do lifting motion in the Y direction under the driving of the lifting structure, and the turntable 21 can receive the tested object 4 on the substrate 1 when lifting. The turntable is rotatably arranged on the lifting structure at the same time, and the turntable is driven by external force to rotate around the Y direction after bearing the measured object 4. Further, the lifting structure is fixed on the frame 1, and the turntable can also move along the X direction under the drive of the frame 1, so that the adjustment of the Y-direction offset of the measured object is realized.

In the embodiment of the present disclosure, the first adjusting assembly 2 further includes a first driving unit 26, where the first driving unit 26 is configured to push the rotation of the adapter block 25, specifically, the first driving unit 26 has a push rod 261 that can move toward or away from the adapter block 25, and a first motor 262. One end of the push rod 261 is movably connected to the adapter 25, and one end is connected to the first motor 262. In order to ensure that the push rod 261 can push the adapter block 25 to rotate around the rotating shaft 211, the push rod 261 needs to be connected to an end of the adapter block 25 away from the rotating shaft 211 to form a rotation moment when pushing.

Referring to fig. 6, a first motor 262 is provided on the frame 21, and the first motor 262 rotates to drive the push rod 261 to rotate. The end face of the conversion block 251 facing the push rod 261 is provided with a screw sleeve 251, the push rod 261 is provided with a thread section matched with the screw sleeve 251, and when the push rod 261 rotates, the thread section rotates in the screw sleeve 251 to drive the conversion block 251 to rotate.

It will be appreciated that in the embodiment of the present disclosure, the two sets of first driving units 26 are symmetrically arranged about the rotation shaft 211, and when the driving lever 22 is driven to rotate, the push rod 261 of one first driving unit 26 moves toward the driving lever 26, and the push rod 261 of the other first driving unit 26 moves away from the driving lever 26.

It will be appreciated that in other embodiments, the number of the first driving units 26 may be one, and when the number of the first driving units 26 is one, the push rod 261 and the adaptor 25 may be adjusted by a universal joint and a telescopic rod, so as to implement the reciprocating swing of the driving lever 22 around the Y direction.

It will be appreciated that in some embodiments the number of dials 23 mounted on the lever 22 may be plural to accommodate adjustment of the position of the dials.

As described above, in the embodiment of the present disclosure, when the frame 21 moves, the function of pushing the object 4 to be measured to move in the X direction by the shift head 23 is provided, and the object 4 to be measured is placed on the base 1 in a spaced manner. When the rack 21 drives the previous measured object 4 to move to the next process in the X direction, the rack 21 can be driven to retract, and the shift head 23 is abutted against the end surface of the measured object 4 facing away from the moving direction again, so as to push the measured object 4 to move in the X direction, in order to realize continuous conveying of the measured object 4 on the base 1 by the first adjusting assembly 2, in the embodiment of the disclosure, the shift head 23 is further required to be rotatably arranged on the shift lever 22 and can rotate around the axis direction of the shift lever 22. And is configured in an eccentric structure, wherein the shifting head 23 has a first position extending out of the bearing surface 11 under the drive of eccentric force and a second position being turned over under the bearing surface under the action of external force; when the frame 21 moves along the X direction, the shifting head 23 is used for pushing the object to be measured to move along the X direction when at the first position.

As shown in fig. 7 and 8, the setting head 23 includes: a pushing surface 232 adapted to abut against the object to be measured; the guiding surface 233 is disposed at an angle to the pushing surface 232 and adapted to receive an external force. The shift head 23 in this embodiment has a right triangle shape, the middle pushing surface 232 corresponds to a plane where the right angle side is located, and the guiding surface 233 corresponds to a plane where the oblique angle side is located. And a limiting structure 234 for limiting rotation of the shift head 23 when it moves to the first position, wherein the guide surface 233 impacts the object to be measured to drive the shift head 23 to move to the second position when the frame 21 moves in the negative direction along the X axis. Referring to fig. 7, the limiting structure 234 is a limiting block disposed at the guide surface 233 and protruding from the guide surface 233. With the mounting mode of the shift head 23 in fig. 4, under the action of the eccentric force, the shift head 23 is driven to rotate anticlockwise on the shift lever 22, and when the shift head rotates to a preset position, the limiting structure 234 is blocked by the limiting part on the frame 21 and cannot rotate continuously, wherein the position is the first position, and the shift head cannot rotate anticlockwise. When the frame 21 advances along the direction X, the pushing surface 232 abuts against the object 4, and the reverse acting force applied by the object 4 does not drive the shift head 23 to rotate anticlockwise, so that the shift head 23 can push the object 4 to move along the direction X. When the rack 21 moves along the negative direction of X, i.e. retreats, the guide surface 233 will strike the rear object 4 preferentially, the shift head 23 will rotate clockwise under the action of the striking force, during the movement, the shift head 23 is gradually pressed down to the lower part of the bearing surface 11 by the object 4, which is the second position, until the shift head 23 slides over the object 4, the first position is restored again under the action of the eccentric force, and the push surface 232 is located on the end surface of the object 4 facing away from the movement direction again, at this time, the rack 21 is driven to move forward along the X direction, and the shift head 23 continues to push the object 4 to move along the X direction, so as to enter the next procedure. The steps are repeated to realize the conveying of the measured object 4.

As shown in fig. 8, in order to ensure that the center of the shift head 23 and the rotation center do not coincide, a balancing weight is disposed on the shift head 23 to adjust the eccentricity of the shift head 23, so as to realize that the pushing surface 232 is parallel to the YZ plane at the first position, and the parallel arrangement of the pushing surface 232 and the YZ plane can ensure that the pushing surface 232 is attached to the measured object 4 when the pushing surface 232 pushes the measured object 4, thereby ensuring the stable movement of the measured object 4 on the carrying surface 11.

In the embodiment of the present disclosure, the feeding manner of the object 4 is to transfer one object at a feeding point of the substrate 1 at a certain interval. However, the distance between the feeding point of the object 4 and the imaging area is larger, which results in a larger advancing or retreating stroke of the frame 21 between the feeding point and the imaging area, and increases the transmission time of the object 4. In order to solve the above-mentioned problem, in the embodiment of the present disclosure, the shifting head 23 is rotatably disposed at one end of the frame 21 away from the first adjusting component 2, where the shifting head 23 is disposed at an interval between the shifting head in the first component 2 in the X direction, and the interval distance may be half of the distance between the feeding point and the imaging area, when the frame 21 retreats by an interval distance, the two objects to be measured 4 may be driven to move forward once when the frame advances again, so as to improve the transmission efficiency of the objects to be measured 4.

It can be understood that when the number of the objects to be measured is plural, a plurality of the shifting heads 23 can be adaptively disposed in the X direction, so as to improve the transmission efficiency of the objects 4 to be measured.

As mentioned above, when the measured layer (the detection surface parallel to the main beam surface) of the film or the adhesive layer is offset in the Z direction, the measured layer is also offset from the imaging area due to the shape of the imaging area, and therefore, the embodiment of the present disclosure further includes the second adjusting component 3. When the measured object 4 finishes the offset correction in the Y direction on the first adjusting component 2, the measured object enters the second adjusting component 3 under the pushing of the shifting head 23. Fig. 2 schematically illustrates a process in which the second adjusting member 3 adjusts the offset of the object 4 in the Z direction, as indicated by the double-headed arrow in fig. 2.

Fig. 11 to 13 illustrate a specific structure of the second regulation assembly 3.

A second adjusting assembly 3 disposed on the base 1, the second adjusting assembly 3 including: the support plates 31 are rotatably disposed on the base 1 with the Z axis as a rotation axis, and are adapted to receive a measured object thereon, and in the embodiment of the disclosure, the support plates 31 are of a support beam structure, and in order to stably support the measured object 4, the number of the support plates 31 is two, and are respectively disposed on the base 1 in a hinged manner, wherein hinge seats 33 are respectively and correspondingly disposed on horizontal support arms of two frame bodies 12 of the base 1, so as to realize connection with the support plates 31.

Referring to fig. 15 and 16, the support plate 31 is hinged to the base 1 near one end of the first adjustment assembly 2. And in order to ensure that the object 4 to be measured moves smoothly from the first adjusting assembly 2 to the second adjusting assembly 3, the height of the bearing surface 11 is controlled to be in the Y direction and higher than the upper surface of the supporting plate 31.
