Detailed implementation manners

[0014] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0016] As Figures 1 to 7 shown, a structural diagram of a device for detecting a sodium-ion battery provided by an embodiment of the present invention includes a frame body 1, a directional feeding mechanism 100, a synchronous clamping mechanism 200, a bidirectional drive mechanism 300, and a real-time detection mechanism 400; the directional feeding mechanism 100 is hinged to the side surface of the frame body 1 and is used to receive the sodium-ion battery body 7 to be detected and transfer it; the synchronous clamping mechanism 200 is arranged at the top and bottom of the flap 2, and the synchronous clamping mechanism 200 abuts against both ends of the sodium-ion battery body 7 and is used to fix the position of the sodium-ion battery body 7; the working end of the synchronous clamping mechanism 200 is driven by a synchronous drive unit to drive multiple sodium-ion battery bodies 7 to rotate synchronously; the bidirectional drive mechanism 300 is rotatably installed on the frame body 1, and the bidirectional drive mechanism 300 is connected to the second longitudinal axis 13 in the synchronous clamping mechanism 200 through a drive gear 26 to drive the sodium-ion battery body 7 and the synchronous clamping mechanism 200 to move simultaneously when the synchronous drive unit works; the real-time detection mechanism 400 is arranged on the side surface and both ends of the sodium-ion battery body 7, the real-time detection mechanism 400 is connected to the bidirectional drive mechanism 300, and dynamically detects the outer side surface of the sodium-ion battery body 7 during movement along with the bidirectional drive mechanism 300.

[0017] In an example of the present invention, during use, a plurality of sodium-ion battery bodies 7 are neatly arranged on the side of the frame body 1 through the directional feeding mechanism 100. The synchronous tightening mechanism 200 is used to fix the sodium-ion battery bodies 7, and the arranged synchronous drive unit drives the plurality of sodium-ion battery bodies 7 to rotate synchronously. On the one hand, both ends of the sodium-ion battery bodies 7 are detected. On the other hand, the longitudinal axis two 13 in the rotating state drives the bidirectional drive mechanism 300 to rotate through the drive gear 26, and the bidirectional drive mechanism 300 pushes the real-time detection mechanism 400 to move along the side of the sodium-ion battery body 7 to perform real-time dynamic detection on the outside of the sodium-ion battery body 7.

[0018] As Figure 2 shown, as a preferred embodiment of the present invention, the directional feeding mechanism 100 includes a flap 2, a telescopic member 3, a placement groove 4, a protective pad 5 and a baffle 6; The flap 2 is hinged to the side of the frame body 1, and a telescopic member 3 is installed between the frame body 1 and the flap 2 for pushing the flap 2 to swing along the frame body 1; The placement grooves 4 are arranged at equal intervals on the side of the flap 2, and a protective pad 5 is installed in each placement groove 4; A baffle 6 is further installed on the side of the flap 2 to prevent the sodium-ion battery body 7 from falling off.

[0019] In an example of the present invention, the protective pad 5 is made of rubber material to prevent damage to the surface of the sodium-ion battery body 7 during transportation. During use, the elongation of the telescopic member 3 is adjusted by an external controller 14, and the telescopic member 3 pushes the flap 2 to swing along the side of the frame body 1 to deflect the sodium-ion battery body 7 placed on the placement groove 4.

[0020] As Figure 1 , Figure 3 and Figure 4 shown, as another preferred embodiment of the present invention, the synchronous tightening mechanism 200 includes a longitudinal axis one 8, a horizontal rod 9, a C-shaped rod 10, an elastic support member one 11, a pull handle 12 and a longitudinal axis two 13; The horizontal rod 9 is arranged in the bottom space of the frame body 1, and a plurality of longitudinal axes one 8 are rotatably connected to the horizontal rod 9, and the longitudinal axes one 8 are slidably connected to the frame body 1; The bottom end of the horizontal rod 9 is fixedly connected to a C-shaped rod 10, an elastic support member one 11 is sleeved in the C-shaped rod 10 within the frame body 1, and a pull handle 12 is arranged at the bottom of the C-shaped rod 10; The longitudinal axis two 13 is arranged corresponding to the longitudinal axis one 8, and the longitudinal axis one 8 and the longitudinal axis two 13 are respectively abutted against both ends of the sodium-ion battery body 7.

[0021] In an example of the present invention, when the handle 12 is pulled outwards, the handle 12 pulls the U-shaped rod 10 to slide along the bottom of the frame body 1, and the horizontal rod 9 and the longitudinal axis 1 8 move synchronously. After placing a plurality of sodium-ion battery bodies 7 on the longitudinal axis 1 8, the handle 12 is released. Under the action of the elastic support member 1 11, the horizontal rod 9 and the longitudinal axis 1 8 are pushed upwards, and the longitudinal axis 1 8 and the longitudinally arranged longitudinal axis 2 13 cooperate to complete the work of tightly fixing the sodium-ion battery body 7.

[0022] As Figure 4 shown, as another preferred embodiment of the present invention, the synchronous drive unit includes a double-track pulley 17, a synchronous belt 18, and a drive motor 19; A plurality of double-track pulleys 17 are provided and are respectively installed on the longitudinal axis 2 13 and the controller 14, and the plurality of double-track pulleys 17 are in the same horizontal plane; Among them, a synchronous belt 18 is installed on each double-track pulley 17 in a staggered manner to facilitate the synchronous rotation of a plurality of longitudinal axes 2 13 and the controller 14; The longitudinal axis 2 13 is connected to the shaft end of the drive motor 19 installed on the frame body 1 through a coupling.

[0023] In an example of the present invention, when the drive motor 19 works, it drives the longitudinal axis 2 13 at one end to rotate through the arranged coupling. The longitudinal axis 2 13 and the double-track pulley 17 at this position rotate synchronously, and the synchronous belt 18 arranged therewith drives the longitudinal axes 2 13 at other positions to rotate synchronously, thereby driving the sodium-ion battery body 7 and the longitudinal axis 1 8 at the corresponding positions to rotate.

[0024] As Figure 5 and Figure 6 shown, as another preferred embodiment of the present invention, the bidirectional drive mechanism 300 includes a drive lead screw 20, a movable sleeve 21, a bracket 22, an incomplete gear 23, a torsion spring 24, and a limit groove 25; The movable sleeve 21 is installed inside the frame body 1. The movable sleeve 21 is slidably connected to the limit groove 25 opened on the frame body 1. The movable sleeve 21 is driven by the drive lead screw 20 installed inside the frame body 1, and a bracket 22 is installed at the end of the movable sleeve 21; The top end of the drive lead screw 20 is installed with an incomplete gear 23. The incomplete gear 23 is in a meshing state with the drive gear 26. The bottom end of the drive lead screw 20 is also installed with a torsion spring 24. The end of the torsion spring 24 is fixedly connected to the frame body 1.

[0025] In one embodiment of the present invention, when the longitudinal shaft 2 13 rotates, the driving gear 26 moves synchronously therewith. Since the driving gear 26 is meshed with the incomplete gear 23, the incomplete gear 23 and the driving screw 20 can be driven to rotate along the frame 1, thereby pushing the movable sleeve 21 and the bracket 22 to slide along the limiting groove 25 opened on the frame 1. The torsion spring 24 is elastically deformed under the force. When the incomplete gear 23 and the driving gear 26 are in a disengaged state, the torsion spring 24 drives the driving screw 20 to rotate in the opposite direction during the restoration process, thereby pushing the movable sleeve 21 and the bracket 22 to move in the opposite direction, so that the bracket 22 returns to the initial position.

[0026] like Figure 5 and Figure 7 As shown, as another preferred embodiment of the present invention, the real-time detection mechanism 400 includes a guide column 27, a fixing block 28, an elastic support member 29 and a leakage detection head 30; The guide posts 27 are provided in plurality and are symmetrically mounted on the bracket 22; A fixing block 28 is installed at one end of the guide column 27, and the fixing block 28 is connected to an elastic support member 29 sleeved on the guide column 27; A leakage detection head 30 is also installed at the other end of the guide column 27 , and the leakage detection head 30 is electrically connected to the controller 14 external to the frame 1 .

[0027] In one example of the present invention, when the bracket 22 slides along the limit groove 25, the guide column 27, the fixed block 28, the elastic support member 29 and the leakage detection head 30 move synchronously therewith, and the leakage detection heads 30 at multiple positions are in contact with the outer side of the sodium ion battery body 7, so as to facilitate leakage detection of the outer side of the sodium ion battery body 7, and when the leakage detection head 30 contacts the end face of the sodium ion battery body 7, the elastic support member 29 is elastically deformed by force, and the guide column 27 and the leakage detection head 30 move along the end face of the sodium ion battery body 7 to detect it.

[0028] like Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the real-time detection mechanism 400 further includes a leakage detection pad 15 and a leakage detection pad 2 16; The leakage detection gasket 15 is installed at the end of the longitudinal axis 1 8, and the leakage detection gasket 2 16 is installed at the end of the longitudinal axis 2 13; The leakage detection gasket 1 15 and the leakage detection gasket 2 16 are both electrically connected to the external controller 14 to facilitate leakage detection of the sodium ion battery body 7 .

[0029] In one example of the present invention, after the sodium ion battery body 7 is placed on the longitudinal axis 1 8, one end of the sodium ion battery body 7 abuts against the leakage detection gasket 1 15, and the other end of the sodium ion battery body 7 abuts against the leakage detection gasket 2 16, so that leakage detection can be performed on a position that the leakage detection head 30 cannot reach in a tight state.

[0030] In summary, when in actual use, multiple sodium-ion battery bodies 7 are sequentially placed on the placement grooves 4 formed in the flap 2. The bottom end of the sodium-ion battery body 7 abuts against the baffle 6. The elongation of the telescopic member 3 is adjusted by an external controller 14. The telescopic member 3 pushes the flap 2 to swing along the side surface of the frame 1, deflecting the sodium-ion battery body 7 on the placement groove 4. Pull the pull handle 12 outwards. The pull handle 12 pulls the C-shaped rod 10 to slide along the bottom of the frame 1. The horizontal rod 9 and the first longitudinal shaft 8 move synchronously therewith. After multiple sodium-ion battery bodies 7 are placed on the first longitudinal shaft 8, release the pull handle 12. Under the action of the first elastic support member 11, the horizontal rod 9 and the first longitudinal shaft 8 are pushed to move upwards. The first longitudinal shaft 8 and the second longitudinal shaft 13 arranged in cooperation complete the work of tightly fixing the sodium-ion battery body 7. When the driving motor 19 works, one end of the second longitudinal shaft 13 is driven to rotate through the arranged coupling. The second longitudinal shaft 13 and the double-track pulley 17 at this position rotate synchronously therewith, and the second longitudinal shafts 13 at other positions are driven to rotate synchronously through the arranged synchronous belt 18, thereby driving the sodium-ion battery bodies 7 and the first longitudinal shafts 8 at the corresponding positions to rotate. Since the driving gear 26 meshes with the incomplete gear 23, the incomplete gear 23 and the driving lead screw 20 can be driven to rotate along the frame 1 when the second longitudinal shaft 13 rotates, thereby pushing the movable sleeve 21 and the bracket 22 to slide along the limiting groove 25 formed in the frame 1. The guide post 27, the fixed block 28, the second elastic support member 29 and the leakage detection head 30 move synchronously therewith. The leakage detection heads 30 at multiple positions are in contact with the outer side of the sodium-ion battery body 7, so as to facilitate the leakage detection of the outer side of the sodium-ion battery body 7. When the leakage detection head 30 contacts the end face of the sodium-ion battery body 7, the second elastic support member 29 is elastically deformed under force, and the guide post 27 and the leakage detection head 30 move along the end face of the sodium-ion battery body 7 to detect it. At the same time, the first leakage detection gasket 15 and the second leakage detection gasket 16 detect the positions that cannot be contacted by the leakage detection heads 30 at both ends of the sodium-ion battery body 7. After the detection is completed, pull the pull handle 12, and the sodium-ion battery body 7 disengages from the first longitudinal shaft 8. When the incomplete gear 23 is disengaged from the driving gear 26, the torsion spring 24 drives the driving lead screw 20 to rotate in the reverse direction during the process of returning to its original state, thereby pushing the movable sleeve 21 and the bracket 22 to move in the reverse direction, so that the bracket 22 returns to the initial position; this device is convenient for placing the sodium-ion battery body 7, can quickly send multiple sodium-ion battery bodies 7 to the designated positions, has high structural stability during the detection process, and can simultaneously perform leakage detection on both ends and the side of the sodium-ion battery body 7, improving the detection efficiency while ensuring the comprehensiveness of the detection, and can complete the leakage detection work of more sodium-ion battery bodies 7 per unit time.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
