[0063] This application provides a detection device comprising a first imaging mechanism capable of automatically photographing and detecting the top surface of a battery; a second imaging mechanism that extends and retracts to below the bottom surface of the battery to automatically photograph and detect the bottom surface of the battery; and a third imaging mechanism capable of photographing the circumferential sides of the battery as it rotates circumferentially around its central axis. As described above, without flipping the battery, automatic photographing of the top, bottom, and circumferential sides of the battery can be achieved. Its structure is simple and compact, easy to operate, and avoids a series of drawbacks associated with manual inspection.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] like Figure 1-7As shown in the illustration, this application discloses a detection device for detecting the outer surface of a battery. The detection device includes a detection position, a first imaging mechanism 1, a second imaging mechanism 3, and a third imaging mechanism 5. The detection position is used to support the battery 10. The first imaging mechanism 1 is located above the detection position and is used to photograph the top surface of the battery 10. The second imaging mechanism 3 can move to a position below the bottom surface of the battery 10 to photograph the bottom surface of the battery 10. The third imaging mechanism 5 is located to one side of the detection position. The battery 10 includes a central axis perpendicular to the bottom surface of the battery 10. When the battery 10 rotates circumferentially around the central axis, the third imaging mechanism 5 sequentially photographs each circumferential side of the battery 10.

[0066] It should be noted that the circumferential sides of battery 10 are located between the top and bottom surfaces of battery 10; when the battery is rectangular, there are four circumferential sides of battery 10, namely the front, back, left and right sides of battery 10.

[0067] Please see the appendix Figure 3 The central axis of battery 10 is attached Figure 3 The location of the dashed line.

[0068] The detection device of this application includes a first imaging mechanism 1, which can automatically capture images of the top surface of the battery 10; a second imaging mechanism 3, which extends and retracts to the bottom surface of the battery 10 to automatically capture images of the bottom surface of the battery 10; and a third imaging mechanism 5, which can capture images of the circumferential sides of the battery 10 as it rotates around the central axis of the battery 10. As described above, without flipping the battery 10, automatic images of the top surface, bottom surface, and circumferential sides of the battery 10 can be captured. Its structure is simple and compact, easy to operate, and avoids a series of drawbacks associated with manual detection, ensuring the detection effect of the battery, shortening the detection time, and significantly improving its practicality.

[0069] Please see the appendix Figure 3 In some embodiments of this application, the detection device includes a lifting mechanism 2 and a rotating mechanism 4. The lifting mechanism 2 is located above the detection position and is capable of lifting the battery 10 to a position detached from the detection position. A first imaging mechanism 1 is disposed on the lifting mechanism 2 and moves synchronously with the lifting mechanism 2. The rotating mechanism 4 is capable of driving the lifting mechanism 2 to rotate around its central axis to achieve circumferential rotation of the battery 10.

[0070] It should be noted that the rotating mechanism 4 has a rotation axis; when the battery 10 is fixed to the lifting mechanism 2, the rotation axis of the rotating mechanism 4 overlaps with the central axis of the battery 10.

[0071] The lifting mechanism 2 fixes the top surface of the battery 10 to lift the battery 10 upward. When the lifting mechanism 2 fixes the top surface of the battery 10, there is a gap between the first shooting mechanism 1 and the top surface of the battery 10 to avoid the top surface of the battery 10 from causing collision damage to the first shooting mechanism 1.

[0072] When the lifting mechanism 2 lifts the battery 10 to the point of separation from the detection position, it creates a moving space between the bottom surface of the battery 10 and the detection position, allowing the second shooting mechanism 3 to move freely. This enables the second shooting mechanism 3 to move to the bottom surface of the battery 10 without obstruction, thus completing the automatic shooting detection of the bottom surface of the battery 10.

[0073] The rotating mechanism 4 is positioned above the lifting mechanism 2. The rotating mechanism 4 drives the lifting mechanism 2 to rotate, which in turn drives the battery 10, which is fixed to the lifting mechanism 2, to rotate around its central axis, thereby achieving circumferential rotation of the battery 10. During the circumferential rotation of the battery 10, each circumferential side of the battery 10 rotates sequentially to a position opposite to the third shooting mechanism 5, and the third shooting mechanism 5 automatically captures and detects each circumferential side of the battery 10 in sequence.

[0074] The lifting mechanism 2 works in conjunction with the second shooting mechanism 3 to automatically photograph and detect the bottom surface of the battery 10 without flipping it up or down. The rotating mechanism 4, the lifting mechanism 2, and the third shooting mechanism 5 work together to automatically photograph the sides of the battery 10 in all directions. The above structure is simple and compact, easy to operate, and avoids a series of drawbacks of manual inspection, ensuring the detection effect of the battery, shortening the detection time, and greatly improving its practicality.

[0075] Please see the appendix Figure 3 In some embodiments of this application, the lifting mechanism 2 includes a negative pressure adsorption component 21 and a lifting telescopic component 22. The negative pressure adsorption component 21 can generate adsorption force to adsorb and fix the battery. The lifting telescopic component 22 can drive the negative pressure adsorption component 21 together with the battery 10 away from the detection position along a third direction, wherein the third direction is parallel to the central axis.

[0076] It should be noted that the third party is attached. Figure 3 The direction indicated by the middle arrow. The lifting telescopic component 22 drives the battery 10 away from the detection position in a third direction, that is, the lifting telescopic component 22 drives the battery 10 upward. The adsorption force generated by the negative pressure adsorption component 21 is a vacuum negative pressure adsorption force; the adsorption force generated by the negative pressure adsorption component 21 adsorbs onto the top surface of the battery 10.

[0077] The first imaging mechanism 1 is fixed to the negative pressure adsorption component 21. When the battery 10 is in the detection position, the lifting telescopic component 22 drives the negative pressure adsorption component 21 and the first imaging mechanism 1 to the initial position. At this time, the first imaging mechanism 1 maintains a certain distance from the top surface of the battery 10 so that the first imaging mechanism 1 can perform a comprehensive and complete imaging inspection of the top surface of the battery 10 without any blind spots. When the first imaging mechanism 1 completes the imaging inspection of the top surface, the lifting telescopic component 22 drives the negative pressure adsorption component 21 to move closer to the detection position along a third direction until the negative pressure adsorption component 21 contacts the top surface of the battery 10, and the negative pressure adsorption component 21 adsorbs and fixes the top surface of the battery 10. Then, the lifting telescopic component 22 drives the negative pressure adsorption component 21 and the battery 10 to move away from the detection position along a third direction until there is enough space between the bottom surface of the battery 10 and the detection position for the second imaging mechanism 3 to move freely.

[0078] The negative pressure adsorption component 21 has a simple structure and realizes the adsorption and fixation operation of the battery 10. Its action response is stable and reliable. The adsorption force generated can firmly adsorb the battery 10 without causing any scratches or damage to the surface of the battery 10, thus ensuring the surface precision of the battery 10. The lifting telescopic component 22 has a simple structure and realizes the upward lifting operation of the battery 10. Its action response is stable and reliable, and the movement distance can be precisely controlled.

[0079] Furthermore, the first shooting mechanism 1 includes a first camera, which may be a first electronic camera.

[0080] Please see the appendix Figure 3-4 In some embodiments, the negative pressure adsorption assembly 21 includes an electric controller 211, a valve 212, a suction cup 213, and an air pump 214. The electric controller 211 is communicatively connected to the valve 212 and the air pump 214; the suction cup 213 is provided on the bottom surface of the electric controller 211; the suction cup 213 is connected to the air pump 214 through a flexible hose, and the flexible hose is provided with a valve 212 to control the opening and closing of the air passage between the suction cup 213 and the air pump 214. The electric controller 211 controls the valve 212 to open and controls the air pump 214 to remove the air from the suction cup 213, so as to adsorb the suction cup 213 onto the top surface of the battery 10 under vacuum negative pressure.

[0081] One or more suction cups 213 are provided; preferably, multiple suction cups 213 are provided, and the multiple suction cups 213 are divided into four groups. The four groups of suction cups 213 are distributed at the four corners of the bottom surface of the electric controller 211 to uniformly and comprehensively adsorb and fix the battery 10. Further, the first shooting mechanism 1 is fixed to the bottom surface of the electric controller 211 and is located in the middle area of ​​the bottom surface of the electric controller 211.

[0082] Please see the appendix Figure 3-4In some embodiments, the lifting telescopic assembly 22 may be a linear telescopic assembly. The linear telescopic assembly may be any one of a hydraulic cylinder telescopic assembly, an electric cylinder telescopic assembly, or a pneumatic cylinder telescopic assembly.

[0083] Preferably, the lifting telescopic assembly 22 is an electric cylinder telescopic assembly; the electric cylinder telescopic assembly includes a first fixed cylinder 221 and a first telescopic rod 222; the first telescopic rod 222 is capable of telescopic movement relative to the first fixed cylinder 221 in a third direction. An electric controller 211 is fixed to the bottom surface of the first telescopic rod 222 so as to telescopic movement in a third direction under the drive of the first telescopic rod 222.

[0084] Please see the appendix Figure 3 In some embodiments of this application, the third shooting mechanism 5 includes a third camera 51 and a third shooting telescopic assembly 52. ​​The third camera 51 is capable of capturing images of the circumferential sides of the battery 10. The third shooting telescopic assembly 52 is capable of moving the third camera 51 telescopically along a third direction, so that the third camera 51 is positioned opposite the circumferential side of the battery 10. The third direction is parallel to the central axis. Furthermore, the third camera 51 may be a third electronic camera.

[0085] As shown above, by setting the third shooting telescopic component 52, the position of the third camera 51 along the third direction is adjusted, so that the third camera 51 can be positioned relative to the circumferential side of the battery 10, so that the third camera 51 can take a full and complete picture of each circumferential side of the battery 10 without any blind spots.

[0086] Please see the appendix Figure 3-4 In some embodiments, the third telescopic assembly 52 can be a linear telescopic assembly. The linear telescopic assembly can be any one of a motor screw assembly, a hydraulic cylinder telescopic assembly, an electric cylinder telescopic assembly, or a pneumatic cylinder telescopic assembly.

[0087] Preferably, the third telescopic shooting assembly 52 is a motor screw assembly; the third telescopic shooting assembly 52 includes a second slide 521, a second servo motor 522, a second threaded rod 523, and a second slide plate 524. The second slide 521 provides mounting points for the second servo motor 522, the second threaded rod 523, and the second slide plate 524, and the second slide 521 has a second groove extending along a third direction; the second servo motor 522 is fixed to the top of the second groove along the third direction, and the output end of the second servo motor 522 is connected to the second threaded rod 523 for transmission; the second threaded rod 523 is parallel to the third direction, and the bottom end of the second threaded rod 523 is connected to the bearing of the second groove; the second slide plate 524 is threaded onto the outside of the second threaded rod 523, and the second slide plate 524 is fixedly connected to the third camera 51. Furthermore, the second slide plate 524 guides and slides within the second groove to reduce friction and improve the reliability and stability of operation.

[0088] Based on the dimensions of the battery 10 along a third direction, the second servo motor 522 can drive the second threaded rod 523 to rotate, thereby driving the second slide plate 524 and the third camera 51 to adjust their positions along a third direction. This allows the third camera 51 to be positioned relative to the circumferential side of the battery, thus accurately capturing images of each circumferential side of the battery 10 and enhancing its practicality.

[0089] Please see the appendix Figure 3 In some embodiments of this application, the second shooting mechanism 3 includes a second camera 31 and a second shooting telescopic assembly 32. The second camera 31 is capable of shooting the bottom surface of the battery 10. The second shooting telescopic assembly 32 is capable of driving the second camera 31 to extend and retract along a second direction, so that the second camera 31 moves to the bottom surface of the battery 10. The second direction is perpendicular to the third direction. Furthermore, the second camera 31 may be a second electronic camera.

[0090] It should be noted that the second direction is attached. Figure 3 The direction indicated by the middle arrow.

[0091] As described above, by setting the second shooting telescopic component 32, the position of the second camera 31 along the second direction is adjusted so that the second camera 31 can move to the bottom of the battery 10 and be positioned opposite the bottom of the battery 10, so that the second camera 31 can take a full and complete picture of the bottom of the battery 10 without any blind spots.

[0092] Please see the appendix Figure 3-4 In some embodiments, the second telescopic shooting component 32 may be a linear telescopic component; the linear telescopic component may be any one of a motor screw component, a hydraulic cylinder telescopic component, an electric cylinder telescopic component, or a pneumatic cylinder telescopic component.

[0093] Preferably, the second telescopic shooting component 32 is a motor lead screw assembly; please refer to the appendix. Figure 4-5 The second telescopic camera assembly 32 includes a first slide 321, a first servo motor 322, a first threaded rod 323, a first sliding plate 324, and an extension plate 325. The first slide 321 provides mounting points for the first servo motor 322, the first threaded rod 323, the first sliding plate 324, and the extension plate 325. The first slide 321 has a first groove extending along a second direction. The first servo motor 322 is located at the end of the first groove along the second direction away from the detection position, and the output bearing of the first servo motor 322 is inserted into the first groove. The output end of the first servo motor 322 is connected to the first threaded rod 323. The first threaded rod 323 is parallel to the second direction, and the end of the first threaded rod 323 away from the first servo motor 322 is connected to the bearing of the first groove. The first sliding plate 324 is threaded onto the outside of the first threaded rod 323. The extension plate 325 is fixedly connected to the first sliding plate 324 and to the second camera 31. Furthermore, the first slide plate 324 is guided to slide within the first groove to reduce friction and improve the reliability and smoothness of operation.

[0094] When the lifting mechanism 2 lifts the battery 10 upwards, the first servo motor 322 drives the first threaded rod 323 to rotate, thereby driving the first slide plate 324, together with the extension plate 325 and the second camera 31, to move along the second direction towards the battery 10 until they are below the bottom surface of the battery 10, so that the bottom surface of the battery 10 can be accurately photographed, enhancing its practicality.

[0095] Please see the appendix Figure 3 In some embodiments of this application, the rotating mechanism 4 includes a rotating gear set 41 and a rotating rod 42. The rotating rod 42 is drivenly connected to the rotating gear set 41 and fixedly connected to the lifting mechanism 2. The rotating gear set 41 can drive the rotating rod 42 and the lifting mechanism 2 to rotate.

[0096] It should be noted that the first fixing cylinder 221 of the lifting telescopic component 22 is fixedly connected to the bottom of the rotating rod 42; the rotating rod 42 is driven to rotate by the rotating gear set 41, the rotation of the rotating rod 42 drives the lifting telescopic component 22 to rotate, the rotation of the lifting telescopic component 22 drives the negative pressure adsorption component 21 to rotate, and the rotation of the negative pressure adsorption component 21 drives the battery 10, which is adsorbed and fixed by the negative pressure adsorption component 21, to rotate.

[0097] The rotary gear set 41 consists of several gears that work together to drive each other. It has the advantages of compact structure, simple maintenance, large transmission ratio, precise control, low noise and high efficiency.

[0098] Please see the appendix Figure 4In some embodiments of this application, the rotating gear set 41 includes a first transmission gear 411, a second transmission gear 412, and a sensing and identification component 413. Please refer to the appendix. Figure 7 The first transmission gear 411 has first transmission teeth arranged along one-quarter of its circumference. The second transmission gear 412 has second transmission teeth arranged along its entire circumference, and the second transmission teeth can mesh with the first transmission teeth for transmission. The second transmission gear 412 is coaxially connected to the rotating rod 42. The first transmission gear 411 includes a first rotational trajectory that meshes with the second transmission gear 412 and a second rotational trajectory that does not mesh with the second transmission gear 412. When the first transmission gear 411 runs to a certain position on the second rotational trajectory, it can trigger the sensing and recognition component 413 to generate a first control signal to control the third shooting mechanism 5 to take a picture.

[0099] It should be noted that when the first transmission tooth of the first transmission gear 411, located in one-quarter of its circumferential direction, meshes with the second transmission tooth of the second transmission gear 412, the first transmission gear 411 drives the second transmission gear 412 to rotate one-quarter of a turn; at this time, the first transmission gear 411 is located on the first rotation trajectory. When the first transmission gear 411 continues to rotate, the first transmission tooth is not located in three-quarters of its circumferential direction, and the first transmission gear 411 cannot drive the second transmission gear 412 to rotate, so the second transmission gear 412 remains in a fixed position; at this time, the first transmission gear 411 is located on the second rotation trajectory. The rotation of the second transmission gear 412 drives the rotating rod 42 to rotate, the rotation of the rotating rod 42 drives the lifting mechanism 2 to rotate, and the rotation of the lifting mechanism 2 drives the battery 10 to rotate.

[0100] As described above, when the first transmission gear 411 rotates and is located on the first rotation trajectory, the second transmission gear 412 drives the battery 10 to rotate a quarter turn. At this time, the first circumferential side of the battery 10 rotates to be opposite the position of the third camera 51. When the first transmission gear 411 continues to rotate and is located on the first rotation trajectory, the second transmission gear 412 and the battery 10 remain stationary, so that the third camera 51 has enough time to focus on the first circumferential side of the battery 10 and complete a clear image of the first circumferential side of the battery 10.

[0101] When the first transmission gear 411 continues to rotate and is located on the second first rotation trajectory, the second transmission gear 412 drives the battery 10 to continue rotating a quarter turn.

[0104] As shown above, the first transmission gear 411 rotates a total of four times to drive the second transmission gear 412 to rotate one time, so that the four circumferential sides of the battery 10 are respectively aligned with the position of the third camera 51, thereby completing a complete and clear image of each circumferential side of the battery 10.

[0105] Furthermore, the sensing and recognition component 413 can automatically identify whether the first transmission gear 411 has run to the second rotation trajectory, so as to automatically trigger the automatic shooting function of the third camera 51, avoiding manual control of the shooting command, and thus realizing automatic shooting of the various circumferential sides of the battery 10, with a high degree of automation.

[0117] Furthermore, multiple first fasteners 913 are provided, and the multiple first fasteners 913 are divided into four groups. The four groups of first fasteners 913 are respectively fixed to the four corners of the cover plate 912.

[0118] Please see the appendix Figure 1 In some embodiments of this application, the supporting mechanism 9 includes a detection platform 92, support legs 93, and support columns 94.

[0119] As mentioned above, the protective box 91 provides support and fixing points for the installation of the rotating mechanism 4 and the lifting mechanism 2; and through the support height of the support column 94, the rotating mechanism 4 and the lifting mechanism 2 are positioned above the detection position, so as to realize the lifting of the battery 10 from the detection position to the position above the detection position.

[0120] Please see the appendix Figure 1-4 In some embodiments of this application, the detection device includes a conveying mechanism 6, which is used to convey the battery 10 from the loading position to the detection position along a first direction.

[0121] The first direction is attached. Figure 1 The direction indicated by the middle arrow. Conveying mechanism 6 can be either a robotic arm mechanism or a belt conveyor mechanism.

[0122] Preferably, the conveying mechanism 6 is a belt conveyor mechanism; the belt conveyor mechanism includes a belt conveyor device 61; the belt conveyor device 61 includes a driving conveyor shaft and a driven conveyor shaft arranged at intervals along a first direction, and a conveyor belt sleeved on the driving conveyor shaft and the driven conveyor shaft. The battery 10 is placed on the conveyor belt and moves from the loading position to the detection position located at the bottom of the protective box 91 under the conveyor belt.

[0123] As described above, by transmitting the battery 10 through the transmission mechanism 6, the displacement of the battery 10 in the first direction can be adjusted so that the battery 10 is accurately positioned at the detection position.

[0124] Please see the appendix Figure 1-4 In some embodiments of this application, the detection device includes a positioning mechanism 7, which includes a first positioning telescopic component 71 and a second positioning telescopic component 72 disposed opposite to each other along a second direction. The first positioning telescopic component 71 and the second positioning telescopic component 72 are respectively located on opposite sides of the detection position. The first positioning telescopic component 71 and the second positioning telescopic component 72 can be relatively close to each other so that the battery 10 is positioned at the detection position.

[0125] It should be noted that the first positioning telescopic assembly 71 and the second positioning telescopic assembly 72 have the same structure and are arranged symmetrically. The first positioning telescopic assembly 71 includes a first linear telescopic member and a first clamping plate 713; the first linear telescopic member can be any one of a hydraulic cylinder telescopic member, an electric cylinder telescopic member, or a pneumatic cylinder telescopic member. Preferably, the first linear telescopic member is an electric cylinder telescopic member; the electric cylinder telescopic member includes a second fixed cylinder 711 and a second telescopic rod 712; the first clamping plate 713 is fixed to the second telescopic rod 712. Similarly, the second positioning telescopic assembly 72 includes a second linear telescopic member and a second clamping plate; the second linear telescopic member can be any one of an electro-hydraulic cylinder telescopic member, an electric cylinder telescopic member, or a pneumatic cylinder telescopic member; the second clamping plate is fixed to the telescopic rod of the second linear telescopic member.

[0126] As described above, by bringing the first linear telescopic member and the second linear telescopic member closer together, the first clamping plate 713 and the second clamping plate clamp the battery 10, and adjust the displacement of the battery 10 in the second direction, so that the battery 10 is accurately positioned at the detection position.

[0127] Furthermore, the first positioning telescopic assembly 71 also includes a support block 714 having a height in a third direction, and a second fixing cylinder 711 fixed to the top of the support block 714 so that the first clamping plate 713 can be positioned opposite the battery 10 in a third direction.

[0128] Furthermore, the second shooting mechanism 3 is fixedly installed above the second fixed cylinder 711.

[0129] Please see the appendix Figure 2-4 In some embodiments of this application, the detection device includes an identification mechanism 8, which can identify the battery 10 that has been transferred to the detection position by the transmission mechanism 6, and send a second control signal to control the first positioning telescopic component 71 and the second positioning telescopic component 72 to move closer to each other, thereby completing the positioning of the battery 10 at the detection position.

[0130] Please see the appendix Figure 2 , 4 It should be noted that the identification mechanism 8 includes a laser receiver 81 and a laser emitter 82. The transmission mechanism 6 also includes a first fixing plate 62 and a second fixing plate 63 spaced apart along a second direction.

Furthermore, the first fixing plate 62 has a first through-mount hole, and the second fixing plate 63 has a second through-mount hole. One of the laser receiver 81 and the laser emitter 82 is fixedly connected to the first through-mount hole, and the other is fixedly connected to the second through-mount hole.

[0131] When the conveying mechanism 6 does not convey the battery 10 along the first direction to the position opposite to the detection position, the laser receiver 81 will continue to receive the laser emitted by the laser emitter 82. When the conveying mechanism 6 conveys the battery 10 along the first direction to the position opposite to the detection position, the battery 10 will block the laser emitted by the laser emitter 82, and the laser receiver 81 will no longer be able to receive the laser. This triggers the identification mechanism 8 to generate a second control signal to automatically control the first positioning telescopic component 71 and the second positioning telescopic component 72 to move closer to each other, thereby adjusting the displacement of the battery 10 in the second direction so that the battery 10 is accurately positioned at the detection position.

[0132] As described above, the identification mechanism 8 can automatically identify whether the conveying mechanism 6 has conveyed the battery 10 to the position opposite to the detection position along the first direction, so as to automatically trigger the automatic positioning function of the positioning mechanism 7, avoiding manual operation of the positioning command, and thus realize the automatic positioning adjustment of the battery 10 in the second direction, with a high degree of automation.

[0133] The testing procedure for photographing the outer surface of battery 10 using the testing device is as follows:

[0134] ① The battery 10 is conveyed from the loading position to the detection position along the first direction by the conveying mechanism 6;

[0135] ② The identification mechanism 8 detects whether the battery 10 has been conveyed to the correct position along the first direction, and automatically generates a second control signal after it has been conveyed to the correct position, so as to control the positioning mechanism 7 to complete the precise positioning of the battery 10 in the second direction; in this way, the battery 10 is precisely positioned at the detection position.

[0136] ③ The first shooting mechanism 1 takes pictures of the top surface of the battery 10 for testing;

[0137] ④ The lifting mechanism 2 adsorbs and fixes the top surface of the battery 10, and lifts the battery 10 upward along the third direction until it leaves the detection position;

[0138] ⑤ The second shooting mechanism 3 moves along the second direction to a position below the bottom surface of the battery 10 and performs shooting detection on the bottom surface of the battery 10;

[0139] ⑥ The third shooting mechanism 5 moves along the third direction to a position opposite to the circumferential side of the battery 10;

[0140] ⑦ The rotating mechanism 4 drives the lifting mechanism 2, together with the battery 10, to rotate along the central axis so that each circumferential side of the battery 10 is in sequence opposite to the position of the third shooting mechanism 5. At the same time, the third shooting mechanism 5 performs shooting detection on each circumferential side of the battery 10.

[0141] It should be noted that steps ⑥-⑦ can be considered as one major step. You can complete step ⑤ first and then steps ⑥-⑦; or you can complete steps ⑥-⑦ first and then step ⑤; or you can complete steps ⑤ and ⑥-⑦ simultaneously.
