Description

Online CT detection equipment

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on November 22, 2023, with application number 202323165273.5 and application name “Online CT Detection Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the technical field of detection equipment, and in particular to an online CT detection equipment. Background Art

[0003] In the production of lithium batteries, after the battery cells are hot pressed, the alignment between the positive and negative electrodes in the battery cells needs to be tested.

[0004] In the related art, the battery cells after hot pressing are scanned and inspected by offline CT (Computed Tomograph) scanning technology. Usually, the battery cells to be inspected are placed on a detection platform, and then the radiation source emits radiation to scan the battery cells. The receiver receives the radiation that has scanned the battery cells to obtain a three-dimensional model of the battery cells, so as to detect the alignment of the positive and negative electrodes in the battery cells.

[0005] However, when offline CT scanning technology is used to scan and inspect battery cells, the battery cells to be inspected need to be manually placed on the inspection platform. After scanning and inspecting one corner or one side of the battery cell, the angle of the battery cell needs to be manually adjusted to continue scanning and inspecting the battery cell. After the inspection is completed, the inspected battery cell needs to be manually removed and another battery cell to be inspected needs to be manually placed on the inspection platform, resulting in poor scanning and inspection efficiency of the battery cells.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0048] In this disclosure, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this disclosure and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0049] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0050] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0051] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0052] As described in the background technology of this application, in the related art, the hot-pressed battery cells are scanned and inspected by offline CT scanning technology. Specifically, after the hot pressing of the battery cells is completed, the staff fixes the hot-pressed battery cells in an upright state on a jig. During the inspection, the ray emitting source emits X-rays that can be irradiated onto the battery cells at a certain angle to the side of the battery cells, and one of the corners of the battery cells is scanned and inspected. The staff then flips the battery cells over to scan and inspect the other corner of the battery cells. The rays that have scanned the battery cells are received by the receiver and can be transmitted to the computer. A three-dimensional model of the battery cells is obtained on the computer, so that the alignment of the positive and negative electrodes of the battery cells can be detected through the three-dimensional model. After the battery cell inspection is completed, the staff removes the battery cells from the jig to fix the next battery cell to be inspected in an upright state on the jig, and scans and inspects the alignment of the positive and negative electrodes of the next hot-pressed battery cell.

[0053] However, the offline CT scanning technology used to scan and inspect hot-pressed battery cells requires manual loading and unloading of the battery cells, and during the inspection process, the battery cells need to be manually flipped, which greatly slows down the inspection efficiency of the battery cells and is not conducive to improving the production efficiency of lithium batteries.

[0054] Based on this, the present application provides an online CT detection equipment, including a turntable, a loading assembly, an unloading assembly and a CT detection assembly. The loading assembly is used to transport the parts to be inspected on the transmission line to the jig located on the loading station. The jig carries the parts to be inspected and rotates with the turntable to the detection station. The CT detection assembly scans the parts to be inspected on the detection station. After the scanning is completed, the parts to be inspected can be rotated with the jig to the unloading station. At the unloading station, the parts to be inspected that have passed the inspection are transported back to the transmission line by the unloading assembly, and the parts to be inspected that have failed the inspection are transported to the unqualified product storage area. As a result, the part to be inspected can be subjected to online computer tomography scanning during the process of being transmitted to the next process through the transmission line, so as to inspect the part to be inspected. For example, when the part to be inspected is a hot-pressed battery cell, the alignment of the positive and negative electrodes of the hot-pressed battery cell can be inspected; and the part to be inspected can be subjected to online CT scanning inspection, without the need for manual loading and unloading during the CT scanning inspection, thereby effectively improving the inspection efficiency of the part to be inspected. That is, when the part to be inspected is a hot-pressed battery cell, the efficiency of CT scanning inspection of the hot-pressed battery cell can be effectively improved.

[0055] The technical solution of this application will be described in detail below with reference to specific embodiments and drawings.

[0056] Example 1

[0057] The embodiment of the present application provides an online CT detection device, as shown in Figures 1 and 2, for detecting a piece to be detected 30 transported on a transmission line 20. The online CT detection device 10 includes a turntable 1, a loading assembly 2, a unloading assembly 3, and a CT detection assembly 4. The turntable 1 has a loading station 11, an inspection station 12, and an unloading station 13. A jig 5 is provided on the turntable 1. The jig 5 can move between the loading station 11, the inspection station 12, and the unloading station 13 along with the turntable 1. The jig 5 is used to carry the piece to be detected 30; the loading assembly 2 is provided on one side of the turntable 1 and is provided close to the loading station 11. The loading assembly 2 is used to transport the piece to be detected 30 from the transmission line 20 to the jig 5 located on the loading station 11; the unloading assembly 3 is arranged on the other side of the turntable 1 and is close to the unloading station 13. The unloading assembly 3 is used to transport the tested parts 30 that have passed the inspection from the fixture 5 located on the unloading station 13 back to the transmission line 20, and to transport the tested parts 30 that have failed the inspection from the fixture 5 located on the unloading station 13 to the unqualified product storage area; and the CT inspection assembly 4 is arranged on one side of the inspection station 12, and is used to scan the tested parts 30 carried by the fixture 5 located on the inspection station 12.

[0058] It should be noted that the arrow shown in FIG. 1 indicates the transmission direction of the to-be-detected part 30 .

[0059] In this embodiment, the jig 5 can move along with the turntable 1 between the loading station 11, the inspection station 12 and the unloading station 13. The jig 5 is used to carry the part to be inspected 30, so that after the part to be inspected 30 is carried on the jig 5, the jig 5 can carry the part to be inspected 30 and move along with the turntable 1 between the loading station 11, the inspection station 12 and the unloading station 13, and the CT detection component 4 is arranged on one side of the inspection station 12, which can be used to scan the part to be inspected 30 carried by the jig 5 located on the inspection station 12, so as to perform CT scanning detection on the part to be inspected 30.

[0060] The loading component 2 is arranged close to the loading station 11, and is used to transport the workpiece 30 to be inspected from the transmission line 20 to the jig 5 located on the loading station 11, so that the workpiece 30 to be inspected located on the transmission line 20 can be automatically loaded onto the jig 5 located on the loading station 11 through the loading component 2. Compared with manually loading the workpiece 30 to be inspected onto the jig 5 located on the loading station 11, the loading speed of the workpiece 30 to be inspected can be effectively improved, thereby effectively improving the inspection efficiency of the workpiece 30 to be inspected and saving manpower. The blanking component 3 is arranged near the blanking station 13, and is used to transport the qualified to be inspected parts 30 from the jig 5 located on the blanking station 13 back to the transmission line 20, and to transport the unqualified to be inspected parts 30 from the jig 5 located on the blanking station 13 to the unqualified product storage area, so that the to be inspected parts 30 that have completed the inspection and are located on the blanking station 13 can be automatically unloaded by the blanking component 3, that is, the qualified to be inspected parts 30 can be automatically transported from the jig 5 located on the blanking station 13 back to the transmission line 20 through the blanking component 3, and the unqualified to be inspected parts 30 can be transported to the unqualified product storage area through the blanking component 3. Compared with the method of manually transporting the qualified to be inspected parts 30 back to the transmission line 20 and transporting the unqualified to be inspected parts 30 to the unqualified product storage area, the blanking efficiency of the to be inspected parts 30 that have completed the inspection can be effectively improved, thereby further improving the efficiency of CT scanning inspection of the to be inspected parts 30 and further saving manpower.

[0061] The part to be detected 30 may be a battery cell, a mobile phone housing, a tablet housing, etc., which is not limited here.

[0062] The CT detection component 4 may include a ray emission source, a detector and a computer. The emission source may be located on one side of the part to be detected 30 (such as the upper side) and may emit rays, such as X-rays, to scan the part to be detected 30 from top to bottom. The detector may be located on the other side of the part to be detected 30 (such as the lower side) and may receive the rays emitted by the emission source and transmit the received rays to the computer. The computer may establish a three-dimensional model of the part to be detected 30 based on the signal transmitted by the detector to detect the part to be detected 30. For example, when the part to be detected 30 is a hot-pressed battery cell, a three-dimensional model of the hot-pressed battery cell may be generated on the computer, so as to obtain the alignment of the positive and negative electrodes of the battery cell.

[0063] Optionally, the above-mentioned turntable 1 may include a base, a rotating shaft and a disc. The disc can be rotatably connected to the base through the rotating shaft. The loading station 11, the inspection station 12 and the unloading station 13 can be respectively arranged at intervals around the rotating shaft. The jig 5 can be set on the disc so that when the disc rotates, the jig 5 can be driven to rotate between the loading station 11, the inspection station 12 and the unloading station 13.

[0064] The above-mentioned loading component 2 has multiple implementation methods. In one possible implementation method, the loading component 2 may include a gantry and a loading mechanical claw arranged on the gantry. The gantry is arranged between the transmission line 20 and the loading station 11. The loading mechanical claw is movably arranged on the gantry to move between the transmission line 20 and the loading station 11 of the turntable 1 to transport the part to be inspected 30 located on the transmission line 20 to the jig 5 located on the loading station 11.

[0065] In another possible implementation, as shown in Figure 1, the loading assembly 2 includes a loading conveyor belt 21, a first loading transport member 22 and a second loading transport member 23, wherein the loading conveyor belt 21 extends in a direction from the transmission line 20 to the turntable 1, and one end of the loading conveyor belt 21 is used to be set close to the transmission line 20, and the other end is set close to the loading station 11; the first loading transport member 22 is movably set between the transmission line 20 and the loading conveyor belt 21, and is used to transport the part to be inspected 30 located on the transmission line 20 to the loading conveyor belt 21; the second loading transport member 23 is movably set between the loading conveyor belt 21 and the loading station 11, and is used to transport the part to be inspected 30 located on the loading conveyor belt 21 to the jig 5 located on the loading station 11.

[0066] Therefore, the distance between the turntable 1 and the transmission line 20 can be arranged according to actual conditions, and the loading conveyor belt 21 can also temporarily store the parts to be inspected 30, so that after the part to be inspected located on the loading station 11 is rotated to the inspection station 12 along with the fixture 5, the next part to be inspected 30 can be promptly transported to the loading station 11 through the second loading transport member 23, and there is no need to wait for the next part to be inspected 30 to be loaded because the next part to be inspected 30 is still on the way to the loading station 11, thereby making the inspection of the parts to be inspected 30 more compact, thereby effectively improving the inspection efficiency of the parts to be inspected 30.

[0067] The loading conveyor belt 21 may be any one of a flat conveyor belt, a roller conveyor belt, a mesh conveyor belt, etc., and is not limited here.

[0068] In addition, the turntable 1 can be positioned on one side of the transmission line 20, and the feed conveyor belt 21 can extend perpendicularly to the direction of extension of the transmission line 20, thereby shortening the length of the feed conveyor belt 21 and saving costs. Of course, the feed conveyor belt 21 can also extend at other angles relative to the direction of extension of the transmission line 20, such as 80°, 60°, etc., which is not limited here and can be set according to actual circumstances.

[0069] Optionally, the first loading and transporting member 22 is used to translate the part to be inspected 30 located on the transmission line 20 to the loading conveyor belt 21; the second loading and transporting member 23 can rotate the part to be inspected 30 during the process of transporting the part to be inspected 30 so that the part to be inspected 30 can be matched and fixed on the jig 5.

[0070] As a result, the first loading and transporting member 22 can have lower transporting requirements, reducing the difficulty of manufacturing the first loading and transporting member 22 and reducing costs; at the same time, the second loading and transporting member 23 can rotate the part to be inspected 30 as needed during the process of transporting the part to be inspected 30 to the loading station 11, so that after the part to be inspected 30 is placed on the jig 5, the jig 5 can be fixed conveniently, and the subsequent CT detection component 4 can scan and detect the part to be inspected 30 on the jig 5.

[0071] For example, when the part 30 to be inspected is a hot-pressed battery cell, and the battery cell is a square battery cell, the battery cell is generally placed in a flat position on the transmission line 20, so that the battery cell can be relatively stable during the transmission process, avoiding the battery cell from being damaged due to tipping over during the transmission process; at this time, the battery cell located in a flat position on the transmission line 20 can be directly translated to the loading conveyor belt 21 by the first loading conveyor 22, so that the battery cell can continue to be transported in a flat position on the loading conveyor belt 21, and when it is transported to the jig 5 on the loading station 11 by the second loading conveyor 23, the second loading conveyor 23 can transport the battery cell to the jig 5, and allow the battery cell to continue to be carried on the jig 5 in a flat position, which facilitates the loading of the battery cell onto the jig 5, and also facilitates the CT detection component 4 to scan and detect the battery cell starting from one top corner of the battery cell.

[0072] The first loading and transporting member 22 includes a guide rail and a manipulator. The guide rail is arranged between the transmission line 20 and the loading conveyor belt 21. The manipulator is slidably connected to the guide rail and can also be lifted and lowered in the vertical direction. The second loading and transporting member 23 includes a four-axis robot.

[0073] In this way, the structure of the first loading and transporting member 22 can be relatively simple and easy to implement, and the second loading and transporting member 23 can rotate the part to be inspected 30 during the process of transporting the part to be inspected 30. The production of four-axis robots is relatively mature and also easy to implement, which reduces costs.

[0074] Of course, the first loading and transporting member 22 may also include a robot, such as a three-axis robot, a four-axis robot, a five-axis robot, etc., which is not limited here.

[0075] The second loading and transporting part 23 can also be a guide rail and a robot. The robot can be slidably set on the guide rail, and the robot can include a rotating motor, a lifting hydraulic cylinder and a clamping claw. The outer shell of the lifting hydraulic cylinder can be slidably connected to the guide rail, the telescopic end of the lifting hydraulic cylinder can be connected to the rotating motor, and the rotating drive end of the rotating motor can be connected to the clamping claw to drive the clamping claw to rotate, and the clamping claw can clamp the part to be inspected 30.

[0076] The above-mentioned manipulator may include a mechanical claw to clamp and pick up the inspection piece 30; or the manipulator may include a suction cup, which is provided with an adsorption hole connected to the vacuum equipment, and the suction cup can pick up the inspection piece 30 by vacuum adsorption; of course, the manipulator can also pick up the inspection piece 30 by other methods, such as adhesive picking, which is not limited here.

[0077] The unloading component 3 may also have multiple implementation methods. In one possible implementation method, the unloading component 3 may include a gantry and a unloading mechanical claw arranged on the gantry. The gantry is arranged between the unloading station 13, the unqualified product storage area and the transmission line 20. The unloading mechanical claw can be movably arranged on the gantry to move between the unloading station 13, the unqualified product storage area and the transmission line 20, and transport the qualified parts to be inspected 30 in the jig 5 located on the unloading station 13 back to the transmission line 20, and transport the unqualified parts to be inspected 30 to the unqualified storage area.

[0078] In another possible implementation of the blanking assembly 3, as shown in FIG1 , the blanking assembly 3 includes a blanking conveyor belt 31, a first blanking transport member 32, a second blanking transport member 33, and a defective product transport assembly, wherein the blanking conveyor belt 31 extends in a direction from the turntable 1 to the transmission line 20, and one end of the blanking conveyor belt 31 is arranged close to the blanking station 13, and the other end is used to be arranged close to the transmission line 20; the first blanking transport member 32 is movably arranged between the blanking station 13 and the blanking conveyor belt 31 The unqualified product conveying component is arranged on one side of the unloading conveyor belt 31, and is used to convey the unqualified product 30 to be inspected that has completed the inspection from the jig 5 located on the unloading station 13 to the unloading conveyor belt 31; the second unloading conveying component 33 is movably arranged between the unloading conveyor belt 31 and the transmission line 20, and is used to convey the unqualified product 30 to be inspected that has passed the inspection from the unloading conveyor belt 31 back to the transmission line 20; and the unqualified product conveying component is arranged on one side of the unloading conveyor belt 31, and is used to convey the unqualified product 30 to be inspected that has failed the inspection from the unloading conveyor belt 31 to the unqualified product storage area.

[0079] In this way, the inspected part 30 can be promptly removed from the unloading station 13 by the first unloading transporting part 32 and temporarily stored on the unloading conveyor belt 31, so that the next inspected part 30 located on the inspection station 12 can be promptly rotated to the unloading station 13 along with the jig 5 after the inspection is completed, and can be transported to the unloading conveyor belt 31 by the first unloading transporting part 32. This reciprocating process can effectively prevent the next inspected part 30 from having to wait on the inspection station 12 after the inspection is completed due to the unloading part 30 located on the unloading station 13 not being removed in time, thereby making the inspection efficiency of the online CT inspection equipment 10 higher.

[0080] The structure of the unloading conveyor belt 31 may be substantially the same as that of the loading conveyor belt 21 , and details may be referred to above, which will not be described again here.

[0081] In addition, the extension direction of the unloading conveyor belt 31 can be perpendicular to the extension direction of the transmission line 20, so that the length of the unloading conveyor belt 31 can be shorter, saving costs; it is also possible that the extension direction of the unloading conveyor belt 31 and the extension direction of the transmission line 20 are at other angles, such as 80°, 60°, etc., which are not limited here and can be set according to actual conditions.

[0082] The first unloading transport member 32 can have a substantially identical structure to the first loading transport member 22, or the second loading transport member 23, without limitation. The second unloading transport member 33 can have a substantially identical structure to the first loading transport member 22, or the second loading transport member 23, without limitation.

[0083] The above-mentioned defective product handling component can have multiple implementation methods. In one possible implementation method, the defective product handling component may include a linear guide rail and a defective product handling robot slidably connected to the linear guide rail. The linear guide rail can be arranged between the unloading conveyor belt 31 and the defective product storage area, so that the defective product robot can slide between the unloading conveyor belt 31 and the defective product storage area. The structure is simple and easy to implement.

[0084] In another possible implementation, as shown in Figure 1, the defective product handling component may include a defective product conveyor belt 35 and a third unloading conveyor 34, wherein the defective product conveyor belt 35 is arranged between the unloading conveyor belt 31 and the defective product storage area; and the third unloading conveyor 34 is movably arranged between the defective product conveyor belt 35 and the unloading conveyor belt 31, and is used to transport the unqualified parts to be inspected 30 from the unloading conveyor belt 31 to the defective product conveyor belt 35.

[0085] In this way, the transporting distance of the third unloading transport member 34 will not be affected by the distance between the unloading conveyor belt 31 and the unqualified product storage area, that is, the transporting path of the third unloading transport member 34 can be shorter, so that the unqualified parts to be inspected 30 located on the unloading conveyor belt 31 can be removed in time, effectively preventing the unqualified parts to be inspected 30 from being transported back to the transmission line 20 due to lack of time to remove them.

[0086] The structure of the defective product conveyor belt 35 may be roughly the same as that of the loading conveyor belt 21 . For details, please refer to the above and will not be described again here.

[0087] Moreover, the defective product conveyor belt 35 can be arranged side by side with the unloading conveyor belt 31, and one end of the defective product conveyor belt 35 can be arranged close to the transmission line 20, so that when the defective product conveyor belt 35 transfers the unqualified parts to be inspected 30 to one end close to the transmission line 20, the unqualified parts to be inspected 30 can be manually removed and placed in the defective product storage area. At the same time, it can also be convenient for the second unloading conveyor 33 to manually transport the qualified parts to be inspected 30 to the transmission line 20, and to manually monitor the parts to be inspected 30 transmitted on the transmission line 20. At the same time, the arrangement of the defective product conveyor belt 35 and the unloading conveyor belt 31 can occupy a smaller space, thereby reducing the space occupied by the online CT detection equipment 10.

[0088] In addition, the length of the defective product conveyor belt 35 can be shorter than the length of the unloading conveyor belt 31. For example, the length of the defective product conveyor belt 35 can be half, 2 / 3, 3 / 4, etc. of the length of the unloading conveyor belt 31. In addition, the third unloading transport member 34 can be arranged at the end of the defective product conveyor belt 35 away from the transmission line 20, so as to facilitate the transportation of the third unloading transport member 34 while making the defective product conveyor belt 35 occupy a smaller space, thereby facilitating the arrangement of the online CT detection equipment 10.

[0089] The structure of the third unloading conveying member 34 may be substantially the same as that of the first loading conveying member 22 , or may be substantially the same as that of the second loading conveying member 23 , which is not limited here.

[0090] Optionally, the blanking assembly 3 also includes a fourth blanking transport member, which is movably arranged between the unqualified product conveyor belt 35 and the unqualified product storage area, and is used to transport the unqualified parts to be inspected 30 from the unqualified product conveyor belt 35 to the unqualified product storage area.

[0091] Thus, the unqualified parts to be tested 30 can be promptly transported to the unqualified storage area by the fourth unloading and transporting member, thereby improving the efficiency of taking out the unqualified parts to be tested 30 and saving manpower.

[0092] The structure of the fourth unloading transport member may be substantially the same as that of the first loading transport member 22 , and details may be referred to above, which will not be described again here.

[0093] Optionally, the online CT detection equipment 10 may also include an identification component, which is arranged downstream of the unloading station 13 and also upstream of the unqualified product handling component. The identification component is electrically connected to the unqualified product handling component. The identification component is used to scan and identify the qualified and unqualified parts 30 to be inspected respectively.

[0094] It needs to be explained that the above-mentioned identification component is arranged downstream of the unloading station 13 and also upstream of the defective product handling component, which means that in the inspection process of the parts to be inspected 30, the identification component is located downstream of the unloading station 13 and upstream of the defective product handling component, and it does not mean that in terms of orientation, the identification component is located downstream of the unloading station 13 and upstream of the defective product handling component.

[0095] In this way, the unqualified parts to be inspected 30 can be detected in time after being removed from the unloading station 13, so that the unqualified product handling component can be controlled in time to transport the unqualified parts to be inspected 30 to the unqualified product storage area, effectively preventing the unqualified parts to be inspected 30 from being transferred to the transmission line 20 by the unloading conveyor belt 31.

[0096] Among them, the recognition component can be an industrial camera, a QR code scanner, a barcode scanner, etc., which is not limited here and can be selected according to actual conditions.

[0097] In addition, the online CT detection equipment 10 may also include a control component, which can be electrically connected to the CT detection component 4, the identification component and the unqualified product handling component respectively, so that when the to-be-detected part 30 detected by the CT detection component 4 is unqualified, the identification code of the unqualified to-be-detected part 30 can be transmitted to the control component, the identification component scans the to-be-detected part 30 unloaded from the unloading station 13 to identify the code, and transmits the scanned identification code of the to-be-detected part 30 to the control component, the control component can compare the identification code transmitted from the identification component with the identification code of the unqualified to-be-detected part 30 transmitted by the CT detection component 4, and once the identification codes are consistent, the unqualified product handling component can be controlled to transport the corresponding to-be-detected part 30 to the unqualified product storage area.

[0098] The online CT detection equipment 10 may also include a code scanning component, which can be arranged upstream of the loading station 11, such as on one side of the transmission line 20, so as to facilitate code scanning and identification of the parts to be detected 30 on the transmission line 20, or on one side of the loading conveyor belt 21, so as to scan and identify the parts to be detected 30 located on the loading conveyor belt 21; and the code scanning and identification component can be electrically connected to the control component to transmit the identification code of the parts to be detected 30 identified by the code scanning to the control component.

[0099] It should be explained that the above-mentioned code scanning component is arranged upstream of the loading station 11, which means that in the inspection process of the part 30 to be inspected, the code scanning component is located upstream of the loading station 11, and does not mean that the code scanning component is located upstream of the loading station 11 in terms of direction position.

[0100] In some embodiments, as shown in FIG2 , the inspection station 12 includes a first inspection station 121 and a second inspection station 122 , and the loading station 11 , the first inspection station 121 , the second inspection station 122 and the unloading station 13 are evenly spaced around the axis of the turntable 1 .

[0101] In this way, the angles between any two adjacent stations among the loading station 11, the first inspection station 121, the second inspection station 122 and the unloading station 13 are all 90°, so that the part to be inspected 30 on the jig 5 can be rotated to the next station every time the turntable 1 rotates 90°, thereby making the rotation control of the jig 5 and the part to be inspected 30 on the jig 5 driven by the turntable 1 relatively simple and easy to implement.

[0102] In addition, the inspection station 12 includes a first inspection station 121 and a second inspection station 122, so that a part of the inspected part 30 can be inspected at the first inspection station 121, and another part of the inspected part 30 can be inspected at the second inspection station 122, so that the inspected part 30 can be inspected in steps, so that the inspected part 30 only needs to rotate around one axis at the first inspection station 121 and the second inspection station 122, thereby making the rotation control of the inspected part 30 at the first inspection station 121 and the second inspection station 122 relatively simple and easy to implement.

[0103] The rotation of the inspected component 30 on the first inspection station 121 may be at any angle, such as 360°, 30°, or 90°, which is not limited here.

[0104] Likewise, the rotation of the inspected component 30 on the second inspection station 122 may be any angle, such as 360°, 30°, or 90°, which is not limited here.

[0105] In other embodiments, as shown in FIG. 2 , the loading station 11 , the inspection station 12 , and the unloading station 13 are respectively provided with jigs 5 .

[0106] In this way, when the jig 5 carries the part to be inspected 30 and moves to the inspection station 12, the part to be inspected 30 that has been inspected on the inspection station 12 can be moved to the unloading station 13 along with the jig 5. The part to be inspected 30 on the jig 5 located on the unloading station 13 can be unloaded at this time, and the empty jig 5 can be moved to the loading station 11, so that the next part to be inspected 30 can be loaded onto the loading station 11. This cycle can be repeated, so that the part to be inspected 30 can be continuously moved to the inspection station 12 for inspection, thereby making the detection efficiency of the online CT detection equipment 10 higher.

[0107] Exemplarily, when the inspection station 12 includes a first inspection station 121 and a second inspection station 122, and the loading station 11, the first inspection station 121, the second inspection station 122, and the unloading station 13 are evenly spaced around the rotation axis of the turntable 1, the second loading transport member 23 can transport the part to be inspected 30 on the loading conveyor belt 21 to the jig 5 on the loading station 11. The turntable 1 is then rotated 90° (e.g., 90° clockwise), and the jig 5 and the part to be inspected 30 on the jig 5 are rotated to the first inspection station 121. At this time, the CT inspection component 4 scans the first corner of the part to be inspected 30. For example, when the part to be inspected 30 is a square battery cell, the CT inspection component 4 scans the first corner of the battery cell, that is, scans the first corner of the battery cell from the upper side of the battery cell downward until the scanning and inspection of the first corner of the battery cell is completed. Then, the turntable 1 can continue to rotate 90°, so that the jig 5 and the part to be tested 30 on the jig 5 are rotated to the second inspection station 122. Still taking the part to be tested 30 as a square battery cell as an example, the battery cell can be rotated to the second corner, so that the second corner of the battery cell rotated to the second inspection station 122 can be located within the detection range of the CT detection component 4 near the second inspection station 122. The CT detection component 4 can scan the second corner of the battery cell to complete the alignment detection of the positive and negative electrodes of the battery cell. Then, the turntable 1 continues to rotate 90°, so that the jig 5 and the part to be tested 30 on the jig 5 that have been inspected are rotated to the unloading station 13, so that the first unloading transporting member 32 can pick up the inspected part to be tested 30 and transport it to the unloading conveyor belt 31, such as the first unloading transporting member 32 can pick up the inspected battery cell and transport it to the unloading conveyor belt 31. Finally, the turntable 1 rotates another 90°, returning the empty jig 5 at the unloading station 13 to the loading station 11, where a new part 30 to be inspected (e.g., a new hot-pressed battery cell to be inspected) can be loaded onto the jig 5. This reciprocating process continues as the turntable 1 rotates, continuously loading the jig 5 at the loading station 11, effectively improving the inspection efficiency of the online CT inspection equipment 10.

[0108] In some embodiments, as shown in FIG. 3 to FIG. 5 , a rotating assembly 6 may be further provided on the turntable 1 , and the fixture 5 may be rotatably disposed on the turntable 1 via the rotating assembly 6 .

[0109] In this way, the jig 5 can drive the part to be inspected 30 to rotate, so that when the CT detection component 4 is on the detection station 12, the part to be inspected 30 can also be rotated by the jig 5 when scanning the part to be inspected 30. Compared with manually rotating the part to be inspected 30, the detection efficiency of the part to be inspected 30 can be effectively improved, thereby further improving the detection efficiency of the online CT detection equipment 10.

[0110] Among them, the rotating component 6 can have multiple implementation methods. In one possible implementation method, the rotating component 6 may include a rotating motor, and the rotating output shaft of the rotating motor is connected to the fixture 5 so that the fixture 5 can rotate around the rotating output shaft of the rotating motor. The structure is simple and easy to implement.

[0111] In a second possible embodiment, as shown in Figures 3-6, the rotating assembly 6 includes a first rotating member 61 and a second rotating member 62, the first rotating member 61 is arranged on the turntable 1, and the rotation output end of the first rotating member 61 is connected to the second rotating member 62, and the rotation output end of the second rotating member 62 is connected to the jig 5, the rotation axis of the first rotating member 61 and the rotation axis of the second rotating member 62 are perpendicular to each other, the first rotating member 61 is used to drive the part to be detected 30 to rotate around the rotation axis of the first rotating member 61, and the second rotating member 62 is used to drive the part to be detected 30 to rotate around the rotation axis of the second rotating member 62, that is, the first rotating member 61 can have a first rotation axis (as shown by the dotted line a1 in Figure 4), the second rotating member 62 can have a second rotation axis (as shown by the dotted line a2 in Figure 4), the first rotation axis can be perpendicular to the second rotation axis, the first rotating member 61 is used to drive the part to be detected 30 to rotate around the first rotation axis, and the second rotating member 62 is used to drive the part to be detected 30 to rotate around the second rotation axis.

[0112] It should be explained that the above-mentioned rotation axis of the first rotating member 61 and the rotation axis of the second rotating member 62 are perpendicular to each other, which means that the rotation axis of the first rotating member 61 and the rotation axis of the second rotating member 62 are approximately perpendicular to each other, and does not mean that the rotation axis of the first rotating member 61 and the rotation axis of the second rotating member 62 must be at an angle of 90°.

[0113] Thus, the jig 5 can drive the part to be detected 30 to rotate around the second rotation axis, so that after one side or one vertex angle of the part to be detected 30 is detected, the other side or another vertex angle of the part to be detected 30 can be flipped around the second rotation axis to a detectable area. Compared with manually flipping the part to be detected 30 carried on the jig 5, not only the detection efficiency of the part to be detected 30 is improved, but also manpower can be saved. And the first rotating member 61 can drive the second rotating member 62 to rotate around the first rotation axis to drive the jig 5 to rotate around the first rotation axis, so that the part to be detected 30 carried on the jig 5 can be rotated around the first rotation axis, so that after one side or one vertex angle of the part to be detected 30 is detected, the part to be detected 30 can flip the other side or another vertex angle around the first rotation axis to a detectable area, further improving the detection efficiency of the part to be detected 30 and further saving manpower. At the same time, it can also make each part of the part to be detected 30 fully scanned and detected, further improving the detection efficiency of the part to be detected 30.

[0114] The angle at which the detected member 30 is rotated by the first rotating member 61 may be 30°, 50°, 180°, 360°, etc., which is not limited here. The rotation angle of the detected member 30 may be adjusted according to actual conditions. Similarly, the angle at which the detected member 30 is rotated by the second rotating member 62 may be 30°, 50°, 180°, 360°, etc., which is not limited here.

[0115] Exemplarily, when the part to be inspected 30 is a square battery cell after hot pressing, and the inspection assembly includes an emission source, a detector and a computer, the battery cell to be inspected is carried on the jig 5. At this time, the emission source can emit X-rays to the battery cell on the jig 5 located on the inspection station 12 to detect the first vertex corner of the battery cell. The detector receives the X-rays passing through the first vertex corner of the battery cell and transmits them to the computer. Specifically, when scanning and inspecting the first vertex corner of the battery cell, while irradiating the battery cell with X-rays, the first rotating member 61 drives the second rotating member 62 to rotate around the first rotating axis, so that the battery cell can rotate around the first rotating axis until the scanning and inspection of the first vertex corner of the battery cell is completed; then The second rotating member 62 can drive the jig 5 to rotate about the second rotation axis, so that the battery cell can rotate about the second rotation axis to rotate the second vertex angle of the battery cell to a position where it can be scanned by X-rays for scanning and detection. The detector receives the X-rays passing through the second vertex angle of the battery cell and transmits them to the computer. In addition, during the scanning of the second vertex angle of the battery cell, the first rotating member 61 drives the second rotating member 62 to rotate about the first rotation axis, so that the second vertex angle of the battery cell can rotate about the first rotation axis until the scanning and detection of the second vertex angle of the battery cell is completed, thereby generating a three-dimensional model of the battery cell on the computer and detecting the alignment of the positive and negative electrode sheets of the battery cell. The operation is simple and convenient. The second vertex angle of the battery cell can be a vertex angle diagonally opposite to the first vertex angle of the battery cell.

[0116] It should be noted that the above is only one embodiment of performing CT scanning on a hot-pressed battery cell. Other parts to be inspected 30 (such as a mobile phone casing, etc.) can also be scanned and inspected using the online CT inspection device 10. In addition, the rotation order and number of rotations of the first rotating member 61 and the second rotating member 62 can be adjusted according to actual conditions. That is, when scanning and inspecting a battery cell, the inspection order of the four corners of the battery cell can be varied and can be adjusted according to actual conditions.

[0117] In addition, when the inspection station 12 includes a first inspection station 121 and a second inspection station 122, and a jig 5 is respectively provided on the loading station 11, the first inspection station 121, the second inspection station 122 and the unloading station, after one side or one corner of the part to be inspected 30 is scanned at the first inspection station 121, the turntable can be rotated by a certain angle to rotate the jig and the part to be inspected 30 on the jig to the second inspection station 122 for continued scanning and inspection, and in the process of the turntable 1 rotating to the second inspection station 122, the jig 5 can drive the part to be inspected 30 to rotate to the other side or another corner, so that when the part to be inspected 30 rotates the turntable 1 to the second inspection station 122, the other side or another corner of the part to be inspected 30 can be within the scanning range of the CT scanning component set near the second inspection station 122, so that the part to be inspected 30 can be scanned by the CT scanning component immediately after it is rotated to the second inspection station 122, thereby effectively improving the scanning efficiency.

[0118] Moreover, while the part to be inspected 30 continues to be scanned and inspected at the second inspection station 122, the first inspection station 121 can scan and inspect the new part to be inspected 30 that is rotated from the loading station 11 along with the fixture 5, so that the first inspection station 121 and the second inspection station 122 can scan and inspect two parts to be inspected 30 at the same time, thereby making the inspection efficiency of the online CT inspection equipment 10 higher.

[0119] For example, when the inspection station 12 includes the first inspection station 121 and the second inspection station 122, the loading station 11, the first inspection station 121, the second inspection station 122 and the unloading station 13 are evenly spaced around the rotation axis of the turntable 1, and the loading station 11, the first inspection station 121, the second inspection station 122 and the unloading station are respectively provided with a jig 5, the second loading transport member 23 can transport the part to be inspected 30 on the loading conveyor belt 21 to the jig 5 on the loading station 11. Then the turntable 1 rotates 90° (such as 90° clockwise), and the jig 5 and the part to be detected 30 on the jig 5 are rotated to the first detection station 121. At this time, the CT detection component 4 scans the first corner of the part to be detected 30, and simultaneously rotates the part to be detected 30 during the scanning detection process until the part to be detected 30 is rotated to a certain angle so that the scanning detection of the first corner of the part to be detected 30 is completed. For example, when the part to be detected 30 is a square battery cell, when the CT detection component 4 scans the first top corner of the battery cell, that is, scans the first top corner of the lower battery cell from the upper side of the battery cell, the first rotating member 61 can simultaneously drive the second rotating member 62 to rotate around the first rotation axis, so that the battery cell can rotate around the first rotation axis until the scanning detection of the first top corner of the battery cell is completed. Then, the turntable 1 can continue to rotate 90°, so that the jig 5 and the part to be detected 30 on the jig 5 are rotated to the second detection station 122. The example of the part to be detected 30 being a square battery cell is still used for explanation. During the process of the turntable 1 rotating 90°, the second rotating member 62 can drive the jig 5 to rotate around the second rotation axis, so that the battery cell can rotate around the second rotation axis and rotate to the second vertex angle. The second vertex angle and the first vertex angle are two vertex angles opposite to each other along the diagonal of the battery cell. Alternatively, after the turntable rotates 90°, the second rotating member 62 drives the jig 5 to rotate around the second rotation axis. The second rotating shaft rotates to rotate the battery cell to the second vertex angle, so that the second vertex angle of the battery cell rotated to the second inspection station 122 can be located within the detection range of the CT inspection assembly 4 near the second inspection station 122. The CT inspection assembly 4 can scan the second vertex angle of the battery cell, and while scanning, the first rotating member 61 drives the second rotating member 62 to rotate around the first rotating shaft, so that the second vertex angle of the battery cell can rotate around the first rotating shaft until the second vertex angle of the battery cell is scanned and inspected, thereby completing the alignment inspection of the positive and negative electrode sheets of the battery cell. In addition, when the part to be inspected 30 continues to be scanned and inspected at the second inspection station 122, the first inspection station 121 can simultaneously scan and inspect the new part to be inspected 30, so that the online CT inspection device 10 can have a more compact beat for the inspection of the part to be inspected 30, thereby making the inspection efficiency of the online CT inspection device 10 higher.

[0120] The first rotating member 61 may include a connecting base and a rotary drive. The connecting base may be fixedly mounted on the turntable 1. The rotary drive may be fixedly mounted on the connecting base. The rotary output end of the rotary drive is connected to the second rotating member 62. The rotary drive may be any one of a servo motor, a stepper motor, a DD (Direct Driver) motor, etc., and is not limited here.

[0121] The second rotating member 62 may have substantially the same structure as the first rotating member 61 , which will not be described in detail herein. Detailed descriptions may be made with reference to the above description.

[0122] Optionally, as shown in Figures 3 and 4, the jig 5 may include a supporting plate 51 and a pressing member 52. The pressing member 52 may be movably arranged on the supporting plate 51 in a direction close to or away from the supporting plate 51 to press the part to be tested 30 between the pressing member 52 and the supporting plate 51, so as to fix the part to be tested 30 more firmly on the supporting plate 51 to prevent the part to be tested 30 from slipping off the jig 5 during the testing process; or the part to be tested 30 may be loosened between the pressing member 52 and the supporting plate 51 to facilitate the removal of the part to be tested 30.

[0123] The pressing member 52 may be any one of a pressing block, a pressing roller, a pressing plate, etc., and is not limited here.

[0124] In addition, the jig 5 may also include a reset elastic member 53, one end of the reset elastic member 53 is connected to the clamping member 52, and the other end is connected to the supporting plate 51. The reset elastic member 53 is used to provide a force for the clamping member 52 to rotate toward the supporting plate 51, so that the part to be tested 30 can be firmly fixed on the jig 5.

[0125] The jig 5 may also include a clamping drive member and a pressure block. The driving end of the clamping drive member is connected to the pressure block, which is used to drive the pressure block to move toward or away from the clamping member 52. When the pressure block squeezes the clamping member 52 in the direction close to the clamping member 52, the clamping member 52 can move in the direction away from the supporting plate 51 to loosen the part to be tested 30 between the clamping member 52 and the supporting plate 51. The operation of removing the part to be tested 30 from the jig 5 is simple and convenient.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
