Description

A battery CT detection device and battery industrial CT detection equipment Technical Field

[0001] The present application relates to the field of battery detection technology, and in particular to a battery CT detection device and a battery industrial CT detection equipment. Background Art

[0002] Power batteries are generally divided into three types: steel-cased batteries, soft-pack batteries, and cylindrical batteries. The two processes commonly referred to as "stacking" and "winding" are precisely the processes used to produce these batteries. Compared to wound batteries, stacked batteries offer advantages in performance, completeness, and space efficiency. With the development of new energy vehicles, stacked batteries have gradually captured a portion of the soft-pack battery market and are widely used in these vehicles. However, stacked batteries require more complex manufacturing processes. The stacking process requires each electrode to be cut twice, and a single battery cell involves dozens to hundreds of cuts. Each cut carries the risk of burrs on the electrode cross-section, as well as misalignment, twisting, and rotation during stacking. This complicates battery quality control.

[0003] Checking the slitting of stacked sheets is a problem that every battery manufacturer has to solve. X-ray inspection equipment is often used. X-rays have good internal perspective effects and can clearly see the internal situation of the battery. The complexity of the stacking process determines the need for higher-performance X-ray inspection equipment. Existing X-ray inspection equipment is limited by the X-ray penetration strength and product thickness. The thicker the product, the worse the penetration effect and the worse the inspection effect. In addition, it only inspects batteries at a single angle and cannot analyze and judge defects such as battery pole misalignment, twisting and rotation.

They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0029] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0030] Please refer to Figures 1 and 2 together. An embodiment of the present application provides a battery CT detection device 2, including a support base 21, a driving mechanism 22 and a detection mechanism 23 arranged on the support base 21; the detection mechanism 23 includes an annular mounting frame 231 rotatably arranged on the support base 21, an X-ray component 232 arranged on the annular mounting frame 231, a flat panel detector component 233, a first mounting frame 234 for mounting the X-ray component 232, and a second mounting frame 235 for mounting the flat panel detector component 233. The first mounting frame 234 and the second mounting frame 235 are symmetrically arranged on the annular mounting frame 231 with respect to the rotation center of the annular mounting frame 231; the driving mechanism 22 drives the annular mounting frame 231 to rotate relative to the support base 21 with the center of the annular mounting frame 231 as the rotation center.

[0031] The annular mounting frame 231 of the detection mechanism 23 is driven by the driving mechanism 22 on the support base 21, and rotates relative to the support base 21 with the center of the annular mounting frame 231 as the rotation center, and the first mounting frame 234 and the second mounting frame 235 are symmetrically arranged on the annular mounting frame 231 with the rotation center of the annular mounting frame 231, thereby driving the X-ray component 232 mounted on the first mounting frame 234 and the flat-panel detector component 233 mounted on the second mounting frame 235 to rotate relative to the support base 21 with the center of the annular mounting frame 231 as the rotation center, and the X-ray component 232 and the flat-panel detector component 233 always remain in a state of being arranged facing each other, thereby realizing CT detection of the battery 1 under inspection at multiple angular positions, so as to provide external software technology with conversion into multiple visual high-precision images of the battery 1 at different angles, thereby realizing accurate analysis and judgment of defects such as misalignment, twisting and rotation of the battery 1 pole piece, effectively improving the detection effect, and being conducive to ensuring the safety of the battery 1.

[0032] Please further refer to Figure 2. In this embodiment, the maximum rotation angle of the annular mounting bracket 231 of the battery CT detection device 2 is less than or equal to ±370°, which can obtain a complete 360° of collected data during detection and calibration, and the extra 10° is the rotation angle required for acceleration and deceleration time; at the same time, it prevents the cable of the detection mechanism 23 from being entangled and stretched due to excessive rotation angle of the annular mounting bracket 231, which is beneficial to extending the service life of the battery CT detection device 2. The battery CT detection device 2 also includes a buffer assembly, which is used to slow down the rotation speed of the annular mounting frame 231 when the annular mounting frame 231 rotates to a point close to the maximum rotation angle, thereby avoiding multiple emergency braking of the annular mounting frame 231. The X-ray component 232 and the flat-panel detector component 233 shake on the annular mounting frame 231 under the action of inertia, causing the connection between the components on the annular mounting frame 231 to wear and loosen, resulting in a positional offset between the X-ray component 232 and the flat-panel detector component 233, which is beneficial to reducing the wear of the battery CT detection device 2 during operation, ensuring the detection effect, and helping to extend the service life of the battery CT detection device 2.

[0033] Optionally, the buffer assembly includes a buffer member 238 provided on the support seat 21 and an abutment block 239 provided on the annular mounting bracket 231 and used to movably abut against the buffer member 238. The abutment block 239 is fixedly connected to the outer wall of the annular mounting bracket 231. When the annular mounting bracket 231 rotates relative to the support seat 21, the abutment block 239 is driven to move relative to the support seat 21 along the outer periphery of the annular mounting bracket 231; when the annular mounting bracket 231 rotates to a position close to the maximum rotation angle, the abutment block 239 abuts against the buffer member 238 on the support seat 21. The buffer member 238 includes a buffer protrusion movably abutted against the abutment block 239 and a buffer guide groove for limiting the moving direction of the buffer protrusion. The abutment block 239 abuts against the buffer protrusion and drives the buffer protrusion to move relative to the support seat 21 along the buffer guide groove. The rotation of the annular mounting frame 231 creates resistance, thereby slowing down the rotation speed of the annular mounting frame 231, so that the rotation speed of the annular mounting frame 231 gradually decreases to a stop; when the annular mounting frame 231 is in a stopped state, the annular mounting frame 231 rotates to the maximum rotation angle, effectively avoiding the X-ray component 232 and the flat-panel detector component 233 from shaking on the annular mounting frame 231 under the action of inertia when the driving mechanism 22 urgently brakes the annular mounting frame 231, causing the connection between the components on the annular mounting frame 231 to wear and loosen, resulting in the position between the X-ray component 232 and the flat-panel detector component 233 being offset, which is beneficial to reducing the wear of the battery CT detection device 2 during operation, ensuring the detection effect, and helping to extend the service life of the battery CT detection device 2.

[0034] Optionally, the support base 21 is provided with an identification block 212 on the outer periphery of the annular mounting frame 231. By providing the identification block 212 on the support base 21, it is convenient for the operator to mark the rotation angle of the annular mounting frame 231 of the detection mechanism 23 relative to the support base 21, thereby facilitating the recording of the scanning angle of the detection mechanism 23 on the battery 1 and the number of collected pictures. The collection angle is proportional to the number of collected pictures. A sufficient number of pictures need to be obtained during 3D reconstruction to facilitate the operator to make accurate inspection results and accurate judgments, and to facilitate the operator to record the work progress and mark the defective position of the battery 1, which is beneficial to ensuring the detection effect, ensuring the safety of the battery 1, and improving the user experience.

[0035] Please further refer to Figures 1 to 3. In this embodiment, the support base 21 of the battery CT detection device 2 is located at the corresponding position of the inner circle of the annular mounting frame 231 and is penetrated by a through hole 211. Battery transmission devices 3 are provided on opposite sides of the support base 21. The battery transmission device 3 on one side transports the battery 1 to the detection station, and the battery transmission device 3 on the other side passes the battery 1 through the through hole 211 and transports it to the detection station, so that the battery CT detection device 2 can simultaneously perform CT detection of multiple angular positions on the two detected batteries 1, so that external software technology can convert them into multiple visual high-precision images of the battery 1 at different angles, thereby realizing accurate analysis and judgment of defects such as misalignment, twisting and rotation of the battery 1 pole piece, and effectively improving the detection effect and detection efficiency.

[0036] Optionally, the detection mechanism 23 further includes a first adjustment component 236 disposed between the X-ray component 232 and the first mounting seat 234. The position of the X-ray component 232 is adjusted by the first adjustment component 236, thereby changing the distance between the X-ray component 232 and the flat panel detector component 233, thereby meeting the use needs of the operator and effectively increasing the applicable range of the battery CT detection device 2; the first adjustment component 236 includes a first adjustment rail 2361 disposed on the first mounting seat 234, a first adjustment frame 2362 slidably disposed on the first adjustment rail 2361, and a first adjustment frame 2362 for driving the first adjustment frame 2362 relative to the first adjustment rail 2361 slides the first adjustment member 2363, and the X-ray component 232 is arranged on the first adjustment frame 2362; the operator drives the first adjustment frame 2362 to slide relative to the first adjustment guide rail 2361 by operating the first adjustment member 2363, so as to drive the X-ray component 232 set on the first adjustment frame 2362 to move relative to the first mounting seat 234 on a preset moving trajectory, thereby changing the distance between the X-ray component 232 and the flat panel detector assembly 233, thereby meeting the operator's usage needs, and at the same time avoiding the position angle between the X-ray component 232 and the flat panel detector assembly 233 from being offset, thereby ensuring the detection effect.

[0037] Optionally, the detection mechanism 23 further includes a second adjustment component 237 provided between the flat panel detector assembly 233 and the second mounting base 235. The position of the flat panel detector assembly 233 is adjusted by the second adjustment component 237, thereby changing the distance between the X-ray assembly 232 and the flat panel detector assembly 233, thereby meeting the use requirements of the operator, effectively expanding the applicable scope of the battery CT detection device 2, and meeting more use scenarios; the second adjustment component 237 includes a second adjustment guide rail 2371 provided on the second mounting base 235, A second adjustment frame 2372 is slidably mounted on the second adjustment guide rail 2371, and a second adjustment member 2373 is used to drive the second adjustment frame 2372 to slide relative to the second adjustment guide rail 2371. The second adjustment frame 2372 is provided with a flat panel detector assembly 233. The operator operates the second adjustment member 2373 to drive the second adjustment frame 2372 to slide relative to the second adjustment guide rail 2371, thereby driving the flat panel detector assembly 233 mounted on the second adjustment frame 2372 to move relative to the second mounting base 235 along a preset movement trajectory, thereby changing the spacing between the X-ray assembly 232 and the flat panel detector assembly 233, thereby meeting the operator's usage requirements and preventing the position angle between the X-ray assembly 232 and the flat panel detector assembly 233 from shifting, thereby ensuring the detection effect. The specific structure of the first adjustment member 2363 and the second adjustment member 2373 is not limited here; optionally, the first adjustment member 2363 and the second adjustment member 2373 are both adjustment bolts.

After the batteries 1 are simultaneously transported to the detection station by the battery transmission devices 3 arranged on opposite sides of the battery CT detection device 2, the two battery transmission devices 3 respectively adjust the two batteries 1 at multiple angular positions, and then the battery CT detection device 2 performs CT detection on the two inspected batteries 1 at multiple angular positions, so as to be converted by external software technology into multiple visual high-precision images of the batteries 1 at different angles, thereby achieving accurate analysis and judgment of defects such as misalignment, twisting and rotation of the battery 1 pole piece, effectively improving the detection effect and detection efficiency, and helping to ensure the safety of the battery 1.

In this embodiment, the battery transmission device 3 includes a support frame 31, a mounting platform 32 arranged on the support frame 31, and an adjustment mechanism 33 for adjusting the position of the mounting platform 32. A accommodating fixture 34 for placing the battery 1 is detachably connected to the mounting platform 32. The adjustment mechanism 33 includes a Y-axis driving member 333, a first X-axis driving member 331, a Z-axis driving member 334, and an R-axis driving member 335, which are arranged between the support frame 31 and the mounting platform 32 and stacked in sequence from bottom to top. The battery transmission device 3 is provided with a mounting table 32 on the support frame 31 for detachably connecting the accommodating fixture 34. The top surface of the accommodating fixture 34 is recessed inward to form a placement groove adapted to the battery 1. The battery 1 to be tested is placed in the placement groove of the accommodating fixture 34, and the accommodating fixture 34 with the battery 1 is carried to prevent collision damage to the battery 1 during transportation, so that the operator can load and unload the battery 1 and quickly fix the accommodating fixture 34 with the battery 1 to a preset position on the mounting table 32. At the same time, the position of the mounting table 32 is adjusted by using the adjustment structure provided between the support frame 31 and the mounting table 32, so that the operator can adjust the position of the mounting table 32 according to the operation requirements. The battery 1 is adjusted to the required angle to facilitate the battery CT detection device 2 to perform CT detection on the battery 1 to be detected at multiple angular positions; the adjustment mechanism 33 includes a Y-axis driving member 333, a first X-axis driving member 331, a Z-axis driving member 334, and an R-axis driving member 335, which are arranged between the support frame 31 and the mounting platform 32 and stacked in sequence from bottom to top.
