The moving and rotating assembly 60 is used for placing an object 80 to be measured, and a rotation center shaft of the horizontal rotator 50 passes through the object 80 to be measured.

Specifically, the base 10 is a base body for supporting, and the base 10 includes a base 11 and a mass 12, the mass 12 being placed on the base 11, the mass 12 being made of a material having a large weight and being not easily deformed, such as marble or the like. A rubber pad is placed between the mass block 12 and the base 11. The base 11 is made of steel, iron and other materials, and the base 11 is provided with supporting legs for adjusting the height or the level. The base 11 can be further provided with a power supply 13 and a control cabinet 14, the power supply 13 supplies power to electric devices such as an X-ray emitter 31 and an X-ray detector 32, and the control cabinet 14 controls each executing device. First stand 21 and second stand 22 all set up in quality piece 12, specifically vertically set up in quality piece 12, have certain distance between first stand 21 and the second stand 22, and first stand 21 can be fixed the setting in quality piece 12, and second stand 22 can the activity set up in quality piece 12, for example, second stand 22 can slide for quality piece 12. The X-ray emitter 31 is used for emitting X-rays, the X-ray detector 32 is used for sensing the X-rays, the X-ray emitter 31 is movably connected with the first upright 21, and the X-ray emitter 31 can slide relative to the first upright 21, for example, the X-ray emitter 31 slides relative to the vertical plane in which the first upright 21 is located. The X-ray detector 32 is movably connected to the second upright 22, and the X-ray detector 32 is slidable relative to the second upright 22, e.g., the X-ray detector 32 slides in a vertical plane relative to the second upright 22.

The translation assembly refers to an assembly moving in a plane, the plane is related to the position of the translation assembly, the first translation assembly 40 is disposed on the base 10, and then the first translation assembly 40 moves in the plane corresponding to the base 10, and when the first translation assembly 40 moves, the horizontal rotator 50, the moving rotation assembly 60 and the object 80 to be measured on the moving rotation assembly 60 are driven to move together. The horizontal rotator 50 is a device that rotates in a horizontal plane, and the moving and rotating assembly 60 is a movable and rotatable assembly, and when performing a spiral scan or an axial scan, the horizontal rotator 50 rotates and drives the moving and rotating assembly 60 and the object 80 to be measured to rotate. The moving and rotating assembly 60 is used for adjusting the position of the area to be scanned of the object 80. The moving and rotating assembly 60 transfers the region to be scanned of the object 80 to the position of the rotation center axis of the horizontal rotator 50 by moving and rotating.

Since the rotation center axis of the horizontal rotator 50 passes through the object 80 to be measured, the region to be scanned of the object 80 to be measured can be moved or rotated to the position of the rotation center axis of the horizontal rotator 50 by moving the rotating assembly 60, and along with the rotation of the horizontal rotator 50, the region to be scanned of the object 80 to be measured is not easy to rotate beyond the coverage of the X-rays emitted by the X-ray emitter 31, that is, is more easy to be irradiated by the X-rays emitted by the X-ray emitter 31.

The X-rays emitted from the X-ray emitter 31 are conical, and when the object 80 rotates with the horizontal rotator 50, the region to be scanned of the object 80 is located in the conical region of the X-rays. The object 80 to be measured may be a battery, and the area to be scanned is a pole piece area of the battery, typically, a corner of the battery. By moving and rotating the moving rotation assembly 60, the angular bisector of one corner of the battery can be brought close to or coincident with the rotation center axis of the horizontal rotator 50, and the range covered by the area to be scanned is minimized as the horizontal rotator 50 rotates.

In a preferred embodiment of the present utility model, referring to fig. 1-3, the moving rotary assembly 60 comprises:

a mover 61 provided to the horizontal rotator 50;

a vertical rotator 62 provided to the mover 61;

a clamp 63 disposed on the vertical rotator 62 and used for clamping the object 80 to be tested;

Wherein the shifter 61 is used for driving the vertical rotator 62 to move in the horizontal direction;

The vertical rotator 62 is used to drive the clamp 63 to rotate in a vertical plane.

Specifically, the mover 61 is a device that moves along a straight line, and the vertical rotator 62, the clamp 63, and the object 80 to be measured can be driven to move along a straight line by the mover 61. The moving direction of the mover 61 is the connecting direction of the first upright 21 and the second upright 22, and the moving direction of the mover 61 may be the connecting direction perpendicular to the first upright 21 and the second upright 22. The vertical rotator 62 refers to a device that rotates in a vertical plane, and the moving direction of the mover 61 may be perpendicular to the vertical plane or may be parallel to the vertical plane. If the moving direction of the mover 61 is perpendicular to the vertical plane where the vertical rotator 62 rotates, the mover 61 and the vertical rotator 62 can move the region to be scanned of the object 80 to be scanned in a larger degree of freedom, which is beneficial to adjusting the position of the region to be scanned of the object 80 to be scanned.

As shown in fig. 2 to 5, the mover 61 includes a mounting base 611, a penetrating screw motor 612, a slider 613, a guide rail 614, and a support plate 615. The penetrating screw motor 612 is arranged on the supporting plate 615 and is rotationally connected with the mounting seat 611, the guide rail 614 is arranged on the mounting seat 611, the guide rail 614 is in sliding connection with the sliding block 613, and the sliding block 613 is arranged on the supporting plate 615. The mounting base 611 is mounted on the horizontal rotator 50, and the support plate 615 is provided with the vertical rotator 62. The vertical rotator 62 includes a vertical plate 621 and a driving member 622, the vertical plate 621 is rotatably connected to the jig 63, the driving member 622 is provided to the vertical plate 621, and the driving member 622 drives the jig 63 to rotate.

The fixture 63 is an apparatus for holding the object 80 to be measured, and the fixture 63 can be flexibly changed to adapt to batteries with different sizes, when the moving direction of the mover 61 is perpendicular to the vertical plane where the vertical rotator 62 rotates, the batteries with different thicknesses can be close to or coincide with the rotation center axis of the horizontal rotator 50 by moving the mover 61.

In a preferred embodiment of the present utility model, referring to fig. 8-13, the first translation assembly 40 is an integral translation assembly, which includes:

the integrated module 41 is formed with a first hole structure 411, a second hole structure 412 and a third hole structure 413;

A first screw 42 disposed in the first hole structure 411 and the second hole structure 412;

A first driving member 43 connected to a first screw 421 of the first screw 42 to drive the first screw 421 to rotate;

A second screw 44 disposed in the third hole 413;

A second driving member 45 connected to a second screw 441 of the second screw 44 to drive the second screw 441 to rotate;

Wherein the central axis of the first aperture structure 411 and the central axis of the second aperture structure 412 coincide;

The central axis of the first hole structure 411 is perpendicular to the central axis of the third hole structure 413.

Specifically, the screw rod refers to a device for converting rotational motion into linear motion, the screw rod includes a screw rod and a nut, the nut is in threaded connection with the screw rod, and when the screw rod rotates, the nut moves along the length direction of the screw rod, thereby converting rotational motion of the screw rod into linear motion of the nut. The first screw 421 of the first screw rod 42 is installed in the first hole structure 411 and the second hole structure 412, the first screw rod 421 is located at a position of a central axis of the first hole structure 411, that is, at a position of a central axis of the second hole structure 412 (the central axes of the first hole structure 411 and the second hole structure 412 are coincident if the first hole structure 411 and the second hole structure 412 are coaxial), the first screw rod 421 is coaxial with the first hole structure 411 (or the second hole structure 412), so long as the first hole structure 411 and the second hole structure 412 are coaxial, it is advantageous to accurately determine the position of the central axis of the first screw rod 421, and a moving direction of the first nut 422 of the first screw rod 42 is the central axis of the first screw rod 421 of the first screw rod 42. The second nut 442 of the second screw rod 44 is installed in the third hole structure 413, the second nut 442 is coaxial with the third hole structure 413, and since the central axis of the third hole structure 413 is perpendicular to the central axis of the first hole structure 411, the central axis of the second nut 442 is perpendicular to the central axis of the first hole structure 411, that is, perpendicular to the central axis of the first screw rod 421 of the first screw rod 42, and thus, the moving direction of the first nut 422 of the first screw rod 42 is perpendicular to the moving direction of the second nut 442 of the second screw rod 44 (that is, the moving direction of the integrated module 41), the orthogonality is higher. In addition, because the movable module assembled and spliced adopts a plurality of parts to be connected and assembled, each part has processing errors, assembly stress can be formed among the parts in the installation process, so that the rigidity is reduced, and deformation can be caused by smaller sizes of the parts. Compared with the assembled and spliced mobile module, the integrated module 41 has higher rigidity, is not easy to deform and is beneficial to long-term use.

The integrated module 41 is formed by integrally processing, and the first hole structure 411, the second hole structure 412 and the third hole structure 413 are structures formed on the integrated module 41, instead of components mounted on the integrated module 41, so that coaxiality of the first hole structure 411 and the second hole structure 412 is improved, and orthogonality of a central shaft of the third hole structure 413 and a central shaft of the first hole structure 411 is improved, and therefore linear motion directions of two screw rods on the integrated module 41 are mutually perpendicular and are less affected by a mounting mode. In addition, with the use of the integral module 41, the first screw 421 of the first screw 42 is restricted within the first hole structure 411 and the second hole structure 412, and the first screw 421 is also not easily deformed.

The first nut 422 of the first screw rod 42 may be connected to the horizontal rotator 50, and of course the second screw rod 44 may be mounted on the mass 12 of the base 10 to enable movement of the horizontal rotator 50 in a horizontal plane. The first aperture structure 411 and the second aperture structure 412 are located on the same side of the unitary module 41, and the first aperture structure 411 and the third aperture structure 413 are located on opposite sides of the unitary module 41.

The length direction of the second screw 441 of the second screw 44 is parallel to the line between the first column 21 and the second column 22, and by driving the rotation of the second screw 441, the second nut 442 of the second screw 44 moves in the direction of the line between the first column 21 and the second column 22, and the distance between the object 80 to be measured and the X-ray emitter 31 and the distance between the object 80 to be measured and the X-ray detector 32 can be adjusted, so that the magnification ratio can be adjusted. The length direction of the first screw 421 of the first screw 42 is perpendicular to the connection line between the first upright 21 and the second upright 22, and by driving the rotation of the first screw 421, the first nut 422 of the first screw 42 moves along the direction perpendicular to the connection line between the first upright 21 and the second upright 22, so that the light emitting direction of the object 80 to be measured to the X-ray emitter 31 can be adjusted.

Because the mass block 12 is not easy to deform (is not easy to deform along with temperature change and is not easy to deform along with the increase of service time), and the integrated module 41 is adopted, the first screw rod 42 and the second screw rod 44 are less affected by installation deviation, and the moving position of the object 80 to be measured in the horizontal plane is kept accurate for a long time.

In a preferred embodiment of the present utility model, referring to fig. 12-13, the integral module 41 has a rib 414 formed thereon, the rib 414 and the first hole structure 411 are located on the same side of the integral module 41, and the integral translation assembly further includes:

the first guide rail 46 abuts against the convex rib 414;

the first slider 47 is slidably connected to the first guide rail 46.

Specifically, since the first nut 422 of the first screw 42 may be coupled to the horizontal rotator 50, the first guide rail 46 may be installed on the integrated module 41 in order to guide the movement of the horizontal rotator 50. In order to make the first guide rail 46 parallel to the central axis of the first hole structure 411, that is, parallel to the central axis of the first screw 421 of the first screw 42, a bead 414 is formed on the integral module 41, the bead 414 being integrally formed with the integral module 41, the bead 414 not being a member mounted on the integral module 41 but being a structure of the integral module 41. The ribs 414 also prevent the first guide rail 46 from deforming during use because the first guide rail 46 abuts the ribs 414. The protruding rib 414 protrudes out of the integrated module 41, the protruding rib 414 abuts against the first guide rail 46 towards the side surface of the first guide rail 46, and after the first guide rail 46 is clung to the side surface, the linearity of the first guide rail 46 is better, and the parallelism with the first screw 421 of the first screw rod 42 is better. The first guide rail 46 may be provided with a first slider 47, the first slider 47 sliding on the first guide rail 46, the first slider 47 being connected to the horizontal rotator 50. The first guide rail 46 and the first slider 47 may also support another moving module.

In a preferred embodiment of the present utility model, referring to fig. 12-13, the integral module 41 has a trapezoid slot 415 formed thereon, and the trapezoid slot 415 and the rib 414 are located on two sides of the first guide rail 46, respectively;

A trapezoid piece 416 is installed in the trapezoid groove 415, and two sides of the trapezoid piece 416 respectively abut against the first guide rail 46 and the inner wall of the trapezoid groove 415.

Specifically, the trapezoid groove 415 refers to a groove structure having a wedge-shaped cross section, and the trapezoid groove 415 is formed in the integrated module 41, not a member mounted on the integrated module 41. The trapezoid groove 415 is located on the integrated module 41 near the rib 414, and the extending direction of the trapezoid groove 415 is parallel to the central axis of the first hole structure 411, i.e. parallel to the side of the rib 414 facing the first guide rail 46. The trapezoid piece 416 and the rib 414 are respectively located on two sides of the first guide rail 46, so that the first guide rail 46 is clamped and fixed. The trapezoid 416 is mounted in the trapezoid slot 415, and since the waists of the trapezoid slot 415 away from the ribs 414 are inclined (the inclination of the two waists of the trapezoid slot 415 is different, i.e. the trapezoid slot 415 is not an isosceles trapezoid slot 415, for example, a right-angle trapezoid slot 415 may be used), after the trapezoid 416 is mounted, the trapezoid 416 tends to move along the direction of the waists, so that pressure is applied to the first guide rail 46, and the first guide rail 46 is pressed against the ribs 414. The trapezoid element 416 may be installed in the trapezoid slot 415 by using a bolt, specifically, a step hole is formed on the trapezoid element 416, a screw hole is formed at the bottom of the trapezoid slot 415, and the bolt may pass through the step hole and be screwed in the screw hole, so that the trapezoid element 416 is installed. The first guide rail 46 may also be mounted on the integrated module 41 by using bolts, specifically, a stepped hole is formed on the first guide rail 46, and a screw hole is formed on the integrated module 41, where the bolts may pass through the stepped hole and be screwed into the screw hole, so as to implement the mounting of the first guide rail 46. During the installation process, the first guide rail 46 may be placed first, and the bolts on the trapezoid pieces 416 may be tightened to install the trapezoid pieces 416, so that the first guide rail 46 is attached to the ribs 414, and then the bolts on the first guide rail 46 are tightened, so that the first guide rail 46 is fixed to the integrated module 41.

In a preferred embodiment of the present utility model, referring to fig. 8-9 and fig. 11-12, the integrated translation assembly further comprises:

A second sliding block 48 disposed on the integral module 41, wherein the second sliding block 48 and the third hole structure 413 are located on the same side of the integral module 41;

A second guide rail 49 slidably connected to the second slider 48;

wherein the second guide rail 49 and the first screw 421 of the first screw 42 each extend to a corresponding position of the X-ray emitter 31.

Specifically, the integrated module 41 mounts the second slider 48, and the second slider 48 extends in the same direction as the direction of movement of the second nut 442 of the second screw 44 as the direction of movement of the central axis parallel to the third hole structure 413. The second slider 48 is provided with a second guide rail 49, and the second guide rail 49 is mounted on the mass 12 of the base 10. The second screw 44 is provided with a second driving member 45, and the second driving member 45 drives a second screw 441 of the second screw 44 to rotate. The second guide rail 49 and the first screw 421 of the first screw 42 are extended to the corresponding positions of the X-ray emitter 31, and the object 80 to be measured can be moved to a position close to the X-ray emitter 31, so that the adjustment range of the magnification ratio can be further widened.

Specifically, the fracture is a structure formed in the integral module 41, and is not a member attached to the integral module 41. The output shaft of the first driving member 43 passes through the fracture and is connected with the first screw 421 of the first screw rod 42, and the first driving member 43 is used for driving the first screw 421 of the first screw rod 42 to rotate, so that the first nut 422 of the first screw rod 42 moves along the central axis of the first hole structure 411, and the moving module connected with the first nut 422 of the first screw rod 42 is driven to move.
