Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a sodium ion battery detection device. Background Art

[0002] Sodium-ion battery is a secondary battery that mainly relies on the movement of sodium ions between the positive and negative electrodes to work. After the sodium ion production is completed, the sodium ions need to be detected and processed. The extrusion block is pushed by a hydraulic rod to move and the sodium-ion battery is squeezed and detected.

[0003] In the application document of a battery extrusion testing machine for lithium battery safety testing proposed with application number 202411314106.9, the setting of the clamping and feeding mechanism is detected, which can realize the engagement of the sliding tooth plate and the arc sliding tooth extrusion column to drive the arc sliding tooth extrusion column to squeeze the tension spring at the non-tooth surface, so that the tension spring begins to gradually move upward. At the same time, the lithium battery can be pushed under the tension spring under the push of the L-shaped push plate, and pulling the first push handle again can make the tension spring quickly clamp the surface of the lithium battery. Compared with the existing technology, which usually places the lithium battery directly on the test bench for extrusion, it is not only cumbersome to operate, but also difficult to ensure the stability and safety of clamping. The advantage of this scheme lies in its innovative extrusion matching mechanism. Through the extrusion matching of the sliding tooth plate and the arc sliding tooth, it is achieved that the tension spring is driven to clamp the lithium battery while pushing the L-shaped push plate, which not only improves the flexibility of operation, but also enhances the stability and safety of clamping.

[0004] When placing parts, personnel need to manually align the positions, resulting in low sodium ion battery placement efficiency. In addition, the battery is continuously squeezed around during battery testing, causing the battery to be subjected to forces on the outside and top during testing, making it difficult for the force on the top to spread outward during testing, which can easily lead to inaccurate sodium ion battery testing. In addition, during the testing process, there is no protective mechanism on the outside of the battery, resulting in a wide range of impact when the lithium battery explodes during testing. Therefore, it is necessary to provide a sodium ion battery testing device to solve the above technical problems. Summary of the Invention

[0038] A clamping member 401 is provided inside the shell 1, a connecting driving member 402 is provided in the middle of the clamping member 401, a conversion member 403 is provided at the bottom of the connecting driving member 402, a rotating shaft 404 is fixedly connected to the middle of the conversion member 403, a winding roller 405 is fixedly sleeved on the outside of one end of the rotating shaft 404, a connecting rope 406 is wrapped around the outside of the winding roller 405, a rope adjusting member 407 is fixedly connected to the top of the connecting rope 406, a driving rope 408 is provided at one end of the rope adjusting member 407, and one end of the driving rope 408 is fixedly connected to the top surface of the extrusion plate 3, so as to realize the clamping and positioning of the lithium battery and the extrusion detection of the center position of the lithium battery.

[0039] The clamping member 401 includes a threaded rod 4011 and a clamping plate 4012;

[0040] Three threaded rods 4011 are provided inside the shell 1, and a cross slot is opened inside the shell 1.

The outer sides of the two threaded rods 4011 are slidably connected with clamping plates 4012, and the outer ends of the other threaded rod 4011 are both connected to clamping plates 4012 by threads. There are four clamping plates 4012, and the outer sides of the clamping plates 4012 are in contact with the inner walls of the cross slot. The movement of the clamping plates 4012 can be achieved by rotating the threaded rods 4011, thereby achieving the clamping of the sodium ion battery. The end faces of the clamping plates 4012 are bonded with rubber plates to avoid damage to the sodium ion battery during clamping.

[0041] The two threaded rods 4011 are connected to the two clamping plates 4012 via a clamping adjustment member 415 . The clamping adjustment member 415 includes a threaded cylinder 4151 and a rectangular adjustment rod 4152 .

[0042] The ends of the two clamping plates 4012 are rotatably embedded in a threaded cylinder 4151, and the two ends of the outer side of the threaded cylinder 4151 are fixedly connected with rectangular adjusting rods 4152.

After the position of the clamping plate 4012 is determined, the personnel adjusts the rectangular adjusting rod 4152 so that the rectangular adjusting rod 4152 contacts the inner wall of the cross groove to limit the threaded cylinder 4151 and ensure the stability of the movement of the threaded cylinder 4151. Subsequently, the movement of the clamping plate 4012 can be realized by rotating the threaded rod 4011, thereby realizing the positioning and clamping of sodium ion batteries of different sizes, thereby expanding the scope of application of the detection equipment.

The fixed cylinder 4072 is fixedly connected to the connecting rope 406. A driving rope 408 is wound on the outer side of the winding shaft 4073. An insertion slot is provided at one end of the top of the moving block 4071, and a plurality of insertion holes are provided at the end of the winding shaft 4073 corresponding to the insertion holes. The latch 4074 is located in the insertion slot and one of the insertion slots, thereby fixing the winding shaft 4073 and thereby driving the rope adjusting member 407 by the driving rope 408.

[0045] After the personnel first move the four clamping plates 4012 to the end of the cross slot, they reel in the driving rope 408 by rotating the reeling shaft 4073 according to the size of different sodium-ion batteries, and adjust the length of the rope wrapped around the outside of the driving rope 408. After adjusting the rope to the appropriate length, the reeling shaft 4073 is then fixed by the pin 4074 to facilitate the extrusion test of different sodium-ion batteries.

[0046] The connecting drive member 402 includes four bevel gears. The first bevel gear is fixedly installed on the outside of the three threaded rods 4011. The second bevel gear is rotatably connected to the bottom surface of the middle part of the cross groove.

The two third bevel gears are meshed and connected. The rotation of the rotating shaft 404 can realize the rotation of the second bevel gear, thereby driving the threaded rod 4011 to rotate.

[0048] A plurality of fixing rods are installed inside the housing 1 by screws, and the connecting rope 406 is slidably connected to the inside of the fixing rods to ensure that the connecting rope 406 moves stably and realizes stable rotation of the rotating shaft 404.

[0049] Example 2

[0050] Based on the first embodiment, Figure 3 、 Figure 6 、 Figure 7 and Figure 9 As shown, the other end of the rotating shaft 404 is fixedly connected to a drive connector 409, and both ends of the top of the drive connector 409 are rotatably connected to a protective cylinder 410. The protective cylinder 410 is rotatably connected to the two ends inside the shell 1. The drive connector 409 includes a three-wheel belt connection structure, a gear drive connection structure, a rotating shaft and two two-wheel belt connection structures. When the rotating shaft 404 rotates, the protection cylinder 410 is rotated through the connection of the drive connector 409, so that the two protection cylinders 410 rotate 90° to form protection on the outside of the sodium ion battery.

[0051] One end of the rotating shaft 404 is fixedly connected to a three-wheel belt connection structure, one end of the three-wheel belt connection structure is fixedly connected to a two-wheel belt connection structure, the other end of the three-wheel belt connection structure is fixedly connected to a gear drive connection structure, one end of the gear drive connection structure is fixedly connected to another two-wheel belt connection structure, and one end of the two two-wheel belt connection structures is provided with a rotating shaft, which is rotatably connected to the inside of the shell 1, and the protective cylinder 410 is fixedly connected to the shell 1. A rubber sleeve is embedded in the outer side of one end of the rotating shaft, and the rubber sleeve is bonded to the inside of one end of the two-wheel belt connection structure, so that the rotating shaft and the two-wheel belt connection structure are frictionally connected. After the protective cylinder 410 rotates 90°, it can be achieved that the two-wheel belt connection structure rotates without driving the protective cylinder 410 to rotate, thereby not affecting the use of the detection equipment.

[0052] A start switch 411 is provided at the bottom of a protective tube 410 at one end of the interior of the housing 1, and a dust collecting and heat dissipating element 412 is provided on the outside of the housing 1. The dust collecting and heat dissipating element 412 includes a dust collecting and heat dissipating element 412, a fixing frame 4121, a collecting frame 4122, a collecting fan 4123 and a connecting pipe 4124;

[0053] A fixing frame 4121 is installed at one end of the top of the shell 1 by screws, and a collecting frame 4122 is slidably connected inside the fixing frame 4121. A collecting fan 4123 is fixedly connected to one end of the fixing frame 4121. One end of the fixing frame 4121 is connected to a protective cylinder 410 through a connecting pipe 4124. The output end of the starting switch 411 is electrically connected to the input end of the collecting fan 4123, and the input end of the starting switch 411 is electrically connected to the output end of the external power supply. After the protective cylinder 410 rotates 90°, the starting switch 411 is turned on and the collecting fan 4123 is started to clean impurities on the surface of the sodium ion battery and ventilate the space formed between the two protective cylinders 410 to better detect and process the sodium ion batteries. At this time, the impurities are collected and processed by the collecting frame 4122. When there are many impurities inside the collecting frame 4122, personnel can clean the impurities in the collecting frame 4122 by moving the collecting frame 4122.

[0054] An air volume adjustment member 416 is provided at one end of the connecting pipe 4124 inside the protective tube 410. The air volume adjustment member 416 includes a baffle 4161 and a fixing screw 4162.

[0055] One end of the protective cylinder 410 is slidably connected to a baffle 4161 through a T-slot, and a fixed screw 4162 is threadedly connected to the inside of the baffle 4161. The end face of the fixed screw 4162 contacts the end face of the T-slot. The personnel moves the baffle 4161 to fit the aperture size of the end of the connecting pipe 4124. After adjusting the aperture of the connecting pipe 4124 to an appropriate size, the baffle 4161 is moved by the fixed screw 4162. By adjusting the aperture of the end of the connecting pipe 4124, the temperature of the space formed between the two protective cylinders 410 is controlled and processed, so that the sodium ion battery can be detected and processed at different temperatures, thereby improving the applicability of the sodium ion detection equipment.

[0056] Example 3

[0057] On the basis of embodiment 1 or 2, Figure 3 and Figure 8 As shown, a gear connector 413 is provided at one end of the rotating shaft 404, and a cleaning member 414 is installed at one end of the gear connector 413 inside the housing 1. The cleaning member 414 includes an adjusting screw 4141, a height adjusting rod 4142 and a cleaning rod 4143;

[0058] An adjusting screw 4141 is rotatably connected to one end of the housing 1, and height adjustment rods 4142 are slidably connected to both ends of the housing 1. One height adjustment rod 4142 is threadedly connected to the adjusting screw 4141, and the tops of the two height adjustment rods 4142 are connected by a cleaning rod 4143. The gear connector 413 includes two parallel gears, which are meshed and connected. One end of the rotating shaft 404 is fixedly connected to a parallel gear, and one end of the adjusting screw 4141 is fixedly connected to another parallel gear. The number of teeth of the parallel gear at the end of the rotating shaft 404 is greater than the number of teeth of the parallel gear at the end of the adjusting screw 4141.

[0059] When the rotating shaft 404 rotates, the adjusting screw 4141 is connected and driven by the gear connecting member 413. The adjusting screw 4141 is threadedly connected to the height adjustment rod 4142 to realize the movement of the height adjustment rod 4142. The movement of the height adjustment rod 4142 drives the movement of the cleaning rod 4143. The cleaning rod 4143 cleans the extrusion surface of the sodium ion battery to avoid the problem that impurities on the surface of the sodium ion battery affect the extrusion detection of the sodium ion battery. By adjusting the height adjustment rod 4142, personnel can adjust the height of the cleaning rod 4143, which is convenient for cleaning sodium ion batteries at different heights.

[0060] After the personnel adjust the rope adjusting member 407 to adjust the driving rope 408 to the appropriate position, according to the actual situation, the personnel adjust the air volume adjusting member 416, and adjust the position of the clamping plate 4012 by the clamping adjusting member 415, adjust the clamping plate 4012 to the appropriate position, and place the sodium ion battery between the four clamping plates 4012. The personnel rotate the rotating shaft 404, and connect the conversion member 403 with the conversion member 403 to realize the movement of the clamping plate 4012, clamp the sodium ion battery, and make the sodium ions be in the center of the shell 1, so as to better detect and process the sodium ions, and no manual positioning is required, which improves the placement of the sodium by the personnel. To improve the efficiency of the sodium ion battery, personnel open the hydraulic rod 2 to drive the extrusion plate 3 to move, and the sodium ion battery is squeezed and tested by the movement of the extrusion plate 3. The movement of the extrusion plate 3 pulls the driving rope 408 to move, and the rope adjustment member 407 is driven to move by the driving rope 408, and then the connecting rope 406 is driven to move. The movement of the connecting rope 406 drives the winding roller 405 to rotate, and the rotating shaft 404 rotates in the opposite direction, so that the clamping plate 4012 is away from the sodium ion battery, so that the sodium ion battery is not clamped at the end when the sodium ion battery is deformed during the extrusion process, so as to avoid the middle and both ends of the sodium ion battery being subjected to force, which affects the sodium ion battery detection. The problem occurs, and as the rotating shaft 404 rotates, the protective cylinder 410 is rotated through the connection of the driving connector 409. When the sodium ion battery is detected, the outer side of the sodium ion battery is protected to avoid the problem of sodium ion explosion affecting the internal parts of the shell 1. The temperature control process can be better during the detection, so that the sodium ion battery can be detected and processed at different temperatures. When the protective cylinder 410 rotates, the dust is collected and the temperature is controlled by starting the switch 411 and the dust collecting and heat dissipating member 412 to ensure the accuracy of the sodium ion battery detection. In this process, the cleaning rod 4143 is driven to move through the connection of the gear connector 413. The surface of the sodium ion battery is cleaned and double-cleaned to improve the cleaning effect of the sodium ion battery and avoid the problem of impurities affecting the detection of the sodium ion battery. After cleaning the sodium ion battery, the cleaning piece 414 is moved to the other end of the shell 1 without affecting the detection of the sodium ion battery. After the sodium ion battery detection is completed and placed for a period of time, if the sodium ion battery does not explode or be damaged, the sodium ion battery is taken out and a new sodium ion battery is placed. Then the personnel rotates the rotating shaft 404 to reset the protective tube 410, the rope adjustment piece 407 and the cleaning piece 414. Then, the next sodium ion battery can be detected and processed according to the above steps.
