[0003] In the production process of lithium batteries, restraint trays are typically used to fix and load the batteries for convenient batch transport and precise positioning. To improve the efficiency of capacity testing, capacity testing equipment usually accommodates multiple restraint trays simultaneously, with each tray loading multiple lithium batteries, thereby increasing the capacity testing efficiency of the equipment.

[0090] Please see Figures 5 to 7 In some embodiments of this application, a restraint tray 20 is provided, comprising: a support assembly 21, a fixing device 22, a clamping device 23, a processing module 24, and a data port 25. The fixing device 22 has at least two components and is used to fix the lithium battery 60 under test. The fixing device 22 is slidably mounted on the support assembly 21. The clamping device 23 is mounted on the support assembly 21 and is used to clamp or release the fixing device 22 to fix the lithium battery 60 under test or to allow at least a portion of the structure of the fixing device 22 to be removed along with the lithium battery 60 under test. The processing module 24 is used to store and process relevant data information of the lithium battery 60 under test. The processing module 24 is disposed on the fixing device 22 so that the processing module 24 can be removed along with the lithium battery 60 under test. Data port 25 is electrically connected to processing module 24. Data port 25 is mounted on fixing device 22. Data port 25 is used to enable processing module 24 to exchange data information with the outside world. Data port 25 is mounted on fixing device 22 so that data port 25 can be removed along with lithium battery 60 under test. During capacity testing, processing module 24 acquires and records data information.

[0091] During the capacity testing of the lithium battery 60 under test, the lithium battery 60 under test is loaded, fixed, and positioned using the restraint tray 20. Multiple lithium batteries 60 under test are loaded onto the restraint tray 20, thus enabling simultaneous capacity testing of multiple lithium batteries 60 under test, thereby improving the capacity testing efficiency. After the lithium battery 60 under test is loaded into the restraint tray 20, it is fixed by the fixing device 22, and the fixing device 22 is clamped by the clamping device 23, thereby fixing and positioning the fixing device 22, and improving the positional accuracy of the lithium battery 60 under test in the restraint tray 20. When it is time to remove the lithium battery 60 under test from the restraint tray 20, the lithium battery 60 under test is released by the clamping device 23, so that at least a portion of the structure in the fixing device 22 can detach from the restraint tray 20 along with the lithium battery 60 under test. A processing module 24 and a data port 25 are provided in the fixing device 22. During the process of at least a portion of the structure in the fixing device 22 detaching from the restraint tray 20 along with the lithium battery 60 under test, the processing module 24 and the data port 25 also detach from the restraint tray 20 along with the portion of the structure in the fixing device 22 and the lithium battery 60 under test. During the capacity grading test of the lithium battery 60 under test, the processing module 24 acquires and records data information about the lithium battery 60 under test. After the capacity grading test is completed, during the process of the external device removing the lithium battery 60 under test from the restraint tray 20, the data information in the processing module 24 is acquired through the data port 25, and the lithium battery 60 under test is classified and placed according to the data information, thereby achieving automatic sorting of the lithium battery 60 under test, thus further improving the capacity grading efficiency of the lithium battery 60 under test.

[0092] Please see Figures 9 to 10 In some embodiments of this application, data port 25 includes a wired port.

[0093] External devices connect to the wired port via data plugs and contact points to exchange data with the processing module 24. During the capacity testing of the lithium battery 60 under test, the capacity testing device 30 connects to the wired port via data plugs and contact points to transmit the test data of the lithium battery 60 to the processing module 24, whereby the processing module 24 stores and processes the data. After the capacity testing of all the lithium batteries 60 under test in the restraint tray 20 is completed, the sorting device 40 sorts the lithium batteries 60 under test according to the test results. During the sorting process, the sorting device 40 connects to the wired port via data plugs and contact points to read the data information about the lithium batteries 60 stored in the processing module 24, and classifies the lithium batteries 60 under test according to the data information, placing different categories of lithium batteries 60 under test into different trays. In this way, the lithium battery 60 under test can be automatically sorted, thereby improving the capacity sorting efficiency of the lithium battery 60 under test.

[0094] In some embodiments of this application, the data port 25 includes a wireless port. The wireless port includes at least one of a Bluetooth interaction port 34 and an NFC interaction port 34.

[0095] External devices interact with the wireless port via wireless interaction port 34, thereby exchanging data information with the processing module 24. During the capacity grading test of the lithium battery 60 under test, the capacity grading test device 30 interacts with the wireless port via wireless interaction port 34, thereby transmitting the test data of the lithium battery 60 under test to the processing module 24, whereby the processing module 24 stores and processes the data information of the lithium battery 60 under test. After the capacity grading test of all the lithium batteries 60 under test in the restraint tray 20 is completed, the sorting device 40 sorts the lithium batteries 60 under test according to the test results. During the sorting process, the sorting device 40 interacts with the wireless port via wireless interaction port 34, thereby reading the data information about the lithium batteries 60 under test stored in the processing module 24, and classifying the lithium batteries 60 under test according to the data information, placing different categories of lithium batteries 60 under test into different trays. In this way, automatic sorting of the lithium batteries 60 under test is achieved, improving the capacity grading efficiency of the lithium batteries 60 under test.

[0096] In some embodiments of this application, the fixing device 22 is also provided with a QR code.

[0097] During the capacity testing of the lithium battery 60 under test, the capacity testing device 30 obtains specific data information of the lithium battery 60 by reading the QR code in the fixing device 22 that holds the lithium battery 60 under test, and records the specific data information of the lithium battery 60 under test into the system, and binds the detected data information about the lithium battery 60 under test with the specific data information of the lithium battery 60 under test. After the capacity testing of all the lithium batteries 60 under test in the restraint tray 20 is completed, the sorting device 40 sorts the lithium batteries 60 under test according to the test results. During the sorting process of the lithium batteries 60 under test, the sorting device 40 obtains specific data information of the lithium battery 60 under test by reading the QR code in the fixing device 22 that holds the lithium battery 60 under test, and queries the data information of the lithium battery 60 under test after the capacity testing based on the specific data information, and classifies the lithium batteries 60 under test according to the data information of the lithium battery 60 under test, and places the lithium batteries 60 under test of different categories into different trays. In this way, the lithium battery 60 under test can be automatically sorted, thereby improving the capacity sorting efficiency of the lithium battery 60 under test.

[0098] In some embodiments of this application, the fixing device 22 is also equipped with an electronic tag. The electronic tag exchanges data information with external devices via wireless communication.

[0099] During the capacity testing of the lithium battery 60 under test, the capacity testing device 30 writes the test data information of the lithium battery 60 under test into an electronic tag via wireless communication. After the capacity testing of all the lithium batteries 60 under test in the restraint tray 20 is completed, the sorting device 40 sorts the lithium batteries 60 under test according to the test results. During the sorting process, the sorting device 40 reads the data information of the lithium battery 60 under test from the electronic tag via wireless communication, and classifies the lithium batteries 60 under test according to the data information, placing different categories of lithium batteries 60 under test into different trays. In this way, the automatic sorting of the lithium batteries 60 under test is achieved, improving the capacity testing efficiency of the lithium batteries 60 under test.

[0100] In some embodiments of this application, the data information includes the internal resistance data, capacity data, production number, etc. of the lithium battery 60 under test.

[0101] In some embodiments of this application, the fixing device 22 includes: a traveling component 221, a first fixing component 222, and a second fixing component 223. The traveling component 221 is provided with a battery slot 2211 for accommodating and fixing the lithium battery 60 under test, and a data port 25 is disposed in the traveling component 221. The first fixing component 222 is provided with a first fixing groove 2221. The second fixing component 223 is slidably connected to the first fixing component 222, and the second fixing component 223 is provided with a second fixing groove 2231, which faces the first fixing groove 2221. During the fixing process of the fixing device 22 fixing the lithium battery 60 under test, the lithium battery 60 is loaded into the traveling component 221, and the fixing device 22 clamps the traveling component 221 between the first fixing component 222 and the second fixing component 223. One side of the traveling component 221 is embedded in the first fixing groove 2221, and the other side of the traveling component 221 is embedded in the second fixing groove 2231. The relative sliding direction of the first fixing component 222 and the second fixing component 223 is toward the direction of the clamping force of the fixing device 22 on the accompanying component 221.

[0102] During the loading and fixing of the lithium battery 60 under test, the fixing device 22 first loads the lithium battery 60 under test into the accompanying component 221, which protects and initially fixes the lithium battery 60 under test. After loading the lithium battery 60 under test into the accompanying component 221, the accompanying component 221 is inserted between the first fixing component 222 and the second fixing component 223, with one side of the accompanying component 221 embedded in the first fixing groove 2221 and the other side embedded in the second fixing groove 2231. The accompanying component 221, which contains the lithium battery 60 under test, is then clamped between the first fixing component 222 and the second fixing component 223, thereby limiting and fixing the accompanying component 221 through the side walls of the first fixing groove 2221 and the second fixing groove 2231.

[0103] The lithium battery under test 60 is loaded by the accompanying component 221. During the handling, fixing, positioning or processing of a single lithium battery under test 60, the accompanying component 221 protects the lithium battery under test 60 and prevents it from being damaged.

[0104] After the accompanying component 221 moves into place, under the force of the clamping device 23, the first fixing component 222 and the second fixing component 223 move closer to each other and clamp the accompanying component 221. Different models of lithium batteries under test 60 require different sizes of accompanying components 221, resulting in different distances between the first fixing component 222 and the second fixing component 223 after clamping the accompanying component 221. This allows the first fixing component 222 and the second fixing component 223 to clamp accompanying components 221 of different sizes, thus enabling the restraint tray 20 to be compatible with different models of lithium batteries under test 60. This improves the compatibility of the restraint tray 20.

[0105] When the lithium battery 60 to be tested needs to be removed individually, the first fixing component 222 and the second fixing component 223 can maintain a tight clamp on the accompanying component 221, thereby removing the lithium battery 60 to be tested from the accompanying component 221, while the accompanying component 221 remains between the first fixing component 222 and the second fixing component 223. During the process of individually loading the lithium battery 60 to be tested, the lithium battery 60 to be tested is placed into the empty accompanying component 221. At this time, the empty accompanying component 221 can be fixed to the loading structure of the lithium battery 60 to be tested, and is also fixed between the first fixing component 222 and the second fixing component 223. The accompanying component 221 protects the lithium battery 60 to be tested, thereby preventing the lithium battery 60 to be deformed by clamping.

[0106] Please see Figure 9 In some embodiments of this application, both the processing module 24 and the data port 25 are located in the accompanying component 221.

[0107] By setting the processing module 24 and data port 25 in the accompanying component 221, the processing module 24 and data port 25 can be transported together with the lithium battery under test 60, so that data information can be exchanged with the outside world at each stage of the processing or testing of the lithium battery under test 60, which facilitates the processing or testing of the lithium battery under test 60.

[0108] In some embodiments of this application, a QR code and / or electronic tag is provided on the accompanying component 221.

[0109] By setting a QR code and / or electronic tag on the accompanying component 221, the QR code and / or electronic tag can be transported together with the lithium battery under test 60, so that data information can be exchanged with the outside world at each stage of the processing or testing of the lithium battery under test 60, which facilitates the processing or testing of the lithium battery under test 60.

[0110] In some embodiments of this application, a restraint tray 20 is provided, comprising: a support assembly 21, a fixing device 22, and a clamping device 23. The fixing device 22 is slidably mounted on the support assembly 21. The fixing device 22 includes a following component 221, a first fixing component 222, and a second fixing component 223. The first fixing component 222 and the second fixing component 223 are arranged opposite to each other, and the distance between them is adjustable. The clamping device 23 is mounted on the support assembly 21 and is used to at least bring the first fixing component 222 and the second fixing component 223 closer together. The first fixing component 222 has a first compression ramp 2222 on its inlet side, and the second fixing component 223 has a second compression ramp 2232 on its inlet side. The first compression ramp 2222 and the second compression ramp 2232 are arranged opposite to each other. The accompanying component 221 has a first pressing protrusion 2212 on the side near the first fixing component 222, and a second pressing protrusion 2213 on the side near the second fixing component 223. When the fixing device 22 fixes the lithium battery 60 to be tested, the lithium battery 60 to be tested is loaded into the accompanying component 221, and the accompanying component 221 enters between the first fixing component 222 and the second fixing component 223 from the inlet side. During the process of the accompanying component 221 entering between the first fixing component 222 and the second fixing component 223, the first pressing protrusion 2212 presses the first pressing slope 2222, and the second pressing protrusion 2213 presses the second pressing slope 2232, so that the first fixing component 222 and the second fixing component 223 overcome the force of the clamping device 23 and move away from each other.

[0111] Different models of lithium batteries under test 60 have different external dimensions. Different accompanying components 221 are designed for different models of lithium batteries under test 60, thereby protecting the lithium batteries under test 60 from damage during transportation and loading. After the lithium batteries under test 60 are loaded into the accompanying component 221, the accompanying component 221 is inserted between the first fixing component 222 and the second fixing component 223 through the inlet of the fixing device 22. The first pressing protrusion 2212 and the second pressing protrusion 2213 respectively press the first pressing inclined surface 2222 and the second pressing inclined surface 2232, thereby causing the first fixing component 222 and the second fixing component 223 to overcome the force of the clamping device 23 and move away from each other. This allows the accompanying component 221 carrying the lithium batteries under test 60 to smoothly enter between the first fixing component 222 and the second fixing component 223. After the accompanying component 221 moves into place, under the force of the clamping device 23, the first fixing component 222 and the second fixing component 223 move closer to each other and clamp the accompanying component 221. Different models of lithium batteries under test 60 require different sizes of accompanying components 221, resulting in different distances between the first fixing component 222 and the second fixing component 223 after clamping the accompanying component 221. This allows the first fixing component 222 and the second fixing component 223 to clamp accompanying components 221 of different sizes, thus enabling the restraint tray 20 to be compatible with different models of lithium batteries under test 60. This improves the compatibility of the restraint tray 20.

[0112] Please see Figures 12 to 14 In some embodiments of this application, the first extrusion protrusion 2212 and the second extrusion protrusion 2213 are respectively provided outward on both sides of the accompanying component 221.

[0113] By having the first pressing protrusion 2212 and the second pressing protrusion 2213 protrude from both sides of the accompanying component 221, the accompanying component 221 enters between the first fixing component 222 and the second fixing component 223. The first pressing protrusion 2212 and the second pressing protrusion 2213 then contact the inner walls of the first fixing component 222 and the second fixing component 223, respectively. This prevents the sidewall of the accompanying component 221 from contacting the inner walls of the first fixing component 222 and the second fixing component 223, thereby reducing the contact area between the accompanying component 221 and the first fixing component 222 and the second fixing component 223. This reduces the frictional resistance when the accompanying component 221 slides relative to the first fixing component 222 and the second fixing component 223, making the process of the accompanying component 221 entering between the first fixing component 222 and the second fixing component 223 smoother.

[0114] In some embodiments of this application, the restraint tray 20 further includes a guide device 26. The guide device 26 guides the fixing device 22 from both sides of the fixing device 22. Both the first fixing component 222 and the second fixing component 223 are guided by the guide device 26.

[0115] As the first fixing component 222 and the second fixing component 223 move closer or further apart, the guide device 26 guides the first fixing component 222 and the second fixing component 223, thereby making their sliding process smoother. Furthermore, the guide device 26 limits the movement of the first fixing component 222 and the second fixing component 223, ensuring that they can only move along the guiding direction of the guide device 26, thus improving the reliability of the restraint tray 20 in positioning the lithium battery 60 under test.

[0116] In some embodiments of this application, the guiding device 26 includes a first guide member 261 and a second guide member 263. The first guide member 261 is provided with a first guide groove 262. The second guide member 263 is provided with a second guide groove 264. The first guide member 261 and the second guide member 263 are respectively disposed on both sides of the fixing device 22. A first ball bearing 224 and a second ball bearing 225 are respectively disposed on both sides of the fixing device 22. The first ball bearing 224 is adapted to the first guide groove 262, and the second ball bearing 225 is adapted to the second guide groove 264. The first ball bearing 224 can roll in the first guide groove 262 along the sliding direction of the fixing device 22, and the second ball bearing 225 can roll in the second guide groove 264 along the sliding direction of the fixing device 22.

[0117] A first ball bearing 224 and a second ball bearing 225 are respectively installed on both sides of the fixing device 22. Both the first ball bearing 224 and the second ball bearing 225 can roll relative to the fixing device 22. During the sliding process of the fixing device 22 relative to the support assembly 21, the first guide member 261 and the second guide member 263 guide the fixing device 22 from both sides, thereby ensuring the stability of the sliding process of the fixing device 22. During the guiding process of the fixing device 22 by the first guide member 261 and the second guide member 263, the first ball bearing 224 rolls in the first guide groove 262, and the second ball bearing 225 rolls in the second guide groove 264. This makes the friction between the fixing device 22 and the guide member 26 during the guiding process of the fixing device 22 a rolling friction force, thereby reducing the resistance during the sliding process of the fixing device 22 and making the sliding process of the fixing device 22 smoother. The guiding device 26 limits the first ball bearing 224 via the first guide member 261 and the second ball bearing 225 via the second guide member 263, thereby limiting the fixing device 22 and positioning it to prevent it from moving within the support assembly 21. During the clamping device 23's fixation of the fixing device 22, the accompanying component 221 is clamped between the first fixing component 222 and the second fixing component 223. The clamping device 23 provides clamping or pushing force, bringing the first fixing component 222 and the second fixing component 223 closer together and tightly clamping the lithium battery 60 under test. Both the first fixing component 222 and the second fixing component 223 can slide relative to the support assembly 21 under the guidance of the guiding device 26, making the distance between them adjustable. This allows the fixing device 22 to accommodate lithium batteries 60 of different thicknesses under test. However, by allowing the fixing device 22 to slide relative to the support assembly 21, the distance between adjacent fixing devices 22 becomes adjustable, thus providing sufficient space between the fixing devices 22 to accommodate lithium batteries 60 of different thicknesses. Once all fixing devices 22 are loaded with lithium batteries 60, the clamping device 23 provides a pushing force, causing adjacent fixing devices 22 to press and squeeze against each other, further clamping the lithium batteries 60 and ensuring the fixing devices 22 remain stably in the desired position, thereby guaranteeing the positional accuracy of the lithium batteries 60 in the restraint tray 20. The guiding device 26 uses rolling balls within the guide groove to facilitate smoother sliding of the first fixing assembly 222, the second fixing assembly 223, and the fixing device 22 as a whole. By installing rolling balls on the fixing device 22, the guiding process during the movement of the fixing device 22 is ensured to occur on a continuous and smooth track, thus guaranteeing the continuity and stability of the sliding of the fixing device 22. Understandably, if the ball bearings are installed on the guide device 26, the fixing device 22 will vibrate or get stuck when passing through adjacent ball bearings.If ball bearings are not installed, the friction between the fixing device 22 and the guide device 26 will be sliding friction, which will increase the resistance of the fixing device 22 during the sliding process and increase the risk of jamming during the sliding process of the fixing device 22.

[0118] Please see Figures 7 to 12 In some embodiments of this application, the first fixing component 222 includes a first fixing member 2225 and a first opening guide member 2224, wherein the first fixing member 2225 and the first opening guide member 2224 are detachably connected. The first fixing member 2225 is provided with a first ball groove, and the first opening guide member 2224 is provided with a second ball groove. The first ball groove and the second ball groove are arranged opposite to each other, and both the first ball groove and the second ball groove are adapted to the first ball member 224. The first ball member 224 is rotatably mounted in the first ball groove and the second ball groove. The first ball member 224 is exposed in the first ball groove on the side away from the second ball groove, and the first ball member 224 is exposed in the second ball groove on the side away from the first ball groove, thereby allowing the first ball member 224 to contact the external structure and roll. The second fixing component 223 includes a second fixing member 2226 and a second opening guide member 2234, wherein the second fixing member 2226 and the second opening guide member 2234 are detachably connected. The second fixing member 2226 is provided with a third ball groove, and the second opening guide member 2234 is provided with a fourth ball groove. The third and fourth ball grooves are arranged opposite to each other, and both the third and fourth ball grooves are adapted to the second ball member 225. The second ball member 225 is rotatably mounted in the third and fourth ball grooves. The second ball member 225 is exposed in the third ball groove on the side away from the fourth ball groove, and the second ball member 225 is exposed in the fourth ball groove on the side away from the third ball groove, thereby allowing the second ball member 225 to contact the external structure and roll.

[0119] By rolling the first ball bearing 224 between the first fixing member 2225 and the first opening guide member 2224, and limiting and positioning the first ball bearing 224 through the first fixing member 2225 and the first opening guide member 2224, the first ball bearing 224 can move with the first fixing component 222 and roll relative to the first fixing component 222. By rolling the second ball bearing 225 between the second fixing member 2226 and the second opening guide member 2234, and limiting and positioning the second ball bearing 225 through the second fixing member 2226 and the second opening guide member 2234, the second ball bearing 225 can move with the second fixing component 223 and roll relative to the second fixing component 223. Thus, during the process of the guiding device 26 guiding the fixing device 22, the first ball bearing 224 rolls in the first guide groove 262 of the first guide member 261, and the second ball bearing 225 rolls in the second guide groove 264 of the second guide member 263. The first ball bearing 224 can be disassembled and assembled by detaching the first opening guide 2224 or installing it onto the first fixing member 2225; similarly, the second ball bearing 225 can be disassembled and assembled by detaching the second opening guide 2234 or installing it onto the second fixing member 2226. This facilitates the replacement or maintenance of both the first and second ball bearings 224 and 225.

[0120] In some embodiments of this application, the first opening guide 2224 is located on the inlet side of the first fixing component 222, and the first opening guide 2224 is provided with a first extrusion slope 2222, which extends from the outside of the first fixing component 222 to the inside of the first fixing component 222; the second opening guide 2234 is located on the inlet side of the second fixing component 223, and the second opening guide 2234 is provided with a second extrusion slope 2232, which extends from the outside of the second fixing component 223 to the inside of the second fixing component 223.

[0121] During the process of placing the accompanying component 221, which carries the lithium battery 60 to be tested, into the first fixing component 222 and the second fixing component 223, the bottom of the accompanying component 221 simultaneously presses against the first pressing slope 2222 and the second pressing slope 2232, thereby separating the first fixing component 222 and the second fixing component 223 from each other, allowing the accompanying component 221 to smoothly enter between the first fixing component 222 and the second fixing component 223. Lithium batteries 60 of different thicknesses are adapted to accompanying components 221 of different sizes. During the pressing of the first pressing slope 2222 and the second pressing slope 2232, the distance at which the first fixing component 222 and the second fixing component 223 separate are different for accompanying components 221 of different sizes, thus allowing the fixing device 22 to automatically adapt to lithium batteries 60 of different thicknesses, improving the compatibility of the restraint tray 20.

[0122] In some embodiments of this application, the bottom of the first fixing component 222 is provided with a first limiting groove 2223, and the bottom of the second fixing component 223 is provided with a second limiting groove 2233. After the accompanying component 221 enters between the first fixing component 222 and the second fixing component 223, the first pressing protrusion 2212 enters the first limiting groove 2223, and the second pressing protrusion 2213 enters the second limiting groove 2233, so that the first fixing component 222 and the second fixing component 223 move closer to each other under the force of the clamping device 23.

[0123] During the process of the accompanying component 221 entering between the first fixing component 222 and the second fixing component 223, the first pressing protrusion 2212 presses the first pressing inclined surface 2222, and the second pressing protrusion 2213 presses the second pressing inclined surface 2232, thereby separating the first fixing component 222 and the second fixing component 223 from each other, so that the accompanying component 221 can smoothly enter between the first fixing component 222 and the second fixing component 223.

[0124] After the first extrusion protrusion 2212 and the second extrusion protrusion 2213 pass over the first extrusion inclined surface 2222 and the second extrusion inclined surface 2232 respectively, the first extrusion protrusion 2212 contacts the inner wall of the first fixing component 222 and protrudes between the accompanying component 221 and the first fixing component 222, thus preventing the inner wall of the first fixing component 222 from contacting the side wall of the accompanying component 221. At the same time, the second extrusion protrusion 2213 contacts the inner wall of the second fixing component 223 and protrudes between the accompanying component 221 and the second fixing component 223, thus preventing the inner wall of the second fixing component 223 from contacting the side wall of the accompanying component 221. Due to the action of the first extrusion protrusion 2212 and the second extrusion protrusion 2213, the side wall of the traveling component 221 does not contact the inner wall of the first fixing component 222 and the second fixing component 223, thereby reducing the contact area between the traveling component 221 and the first fixing component 222 and the second fixing component 223. This reduces the frictional resistance when the traveling component 221 slides relative to the first fixing component 222 and the second fixing component 223, making the process of the traveling component 221 entering between the first fixing component 222 and the second fixing component 223 smoother.

[0125] After the first extrusion protrusion 2212 and the second extrusion protrusion 2213 pass through the inner walls of the first fixing component 222 and the second fixing component 223 respectively, the first extrusion protrusion 2212 enters the first limiting groove 2223 and the second extrusion protrusion 2213 enters the second limiting groove 2233, thereby limiting the first extrusion protrusion 2212 and the second extrusion protrusion 2213 respectively through the inner walls of the first limiting groove 2223 and the second limiting groove 2233. After the first extrusion protrusion 2212 and the second extrusion protrusion 2213 enter the first limiting groove 2223 and the second limiting groove 2233 respectively, under the action of the clamping device 23, the first fixing component 222 and the second fixing component 223 approach each other, so that the inner walls of the first fixing component 222 and the second fixing component 223 respectively fit against the side walls of the accompanying component 221, and the first fixing component 222 and the second fixing component 223 tightly clamp the accompanying component 221, preventing the accompanying component 221 from detaching from the first fixing component 222 and the second fixing component 223. Thus, the accompanying component 221 is fixed by the first fixing component 222 and the second fixing component 223. When the accompanying component 221 is loaded with the lithium battery 60 to be tested, the lithium battery 60 to be tested can be fixed by the fixing device 22. It should be noted that the size of the accompanying component 221 is specifically designed according to the different models of the lithium battery 60 under test, so that the lithium battery 60 under test can be stably and reliably loaded into the accompanying component 221. After the lithium battery 60 under test is loaded into the accompanying component 221, the lithium battery 60 under test is limited and positioned by the inner wall of the accompanying component 221, thereby ensuring the positional accuracy of the lithium battery 60 under test.

[0126] When it is necessary to remove the lithium battery 60 under test from the fixing device 22, the accompanying component 221 can be clamped by an external material handling device, and then the lithium battery 60 under test can be removed together with the accompanying component 221. By clamping the accompanying component 221 to remove the lithium battery 60 under test from the fixing device 22, the direct clamping of the lithium battery 60 under test is avoided, and the protection of the lithium battery 60 under test by the accompanying component 221 reduces the risk of damage to the lithium battery 60 under test.

[0127] During the removal of the accompanying component 221, the first pressing protrusion 2212 and the second pressing protrusion 2213 press against the inner walls of the first limiting groove 2223 and the second limiting groove 2233 respectively, thereby causing the first fixing component 222 and the second fixing component 223 to separate from each other. This allows the first pressing protrusion 2212 and the second pressing protrusion 2213 to smoothly enter between the inner walls of the first fixing component 222 and the second fixing component 223, and to slide relative to the inner walls of the first fixing component 222 and the second fixing component 223 until the accompanying component 221 is removed from the space between the first fixing component 222 and the second fixing component 223, thereby realizing the removal of the accompanying component 221.

[0128] In some embodiments of this application, the first fixing component 222 includes a first fixing member 2225 and a second fixing member 2226, and the second fixing component 223 includes a third fixing member 2235 and a fourth fixing member 2236. The first fixing member 2225 and the third fixing member 2235 are disposed opposite to each other, and the second fixing member 2226 and the fourth fixing member 2236 are disposed opposite to each other. The first fixing member 2225 and the second fixing member 2226 are slidably connected, and the third fixing member 2235 and the fourth fixing member 2236 are slidably connected. The distance in a first direction x between the first assembly 22a formed by the first fixing member 2225 and the third fixing member 2235 and the second assembly 22b formed by the second fixing member 2226 and the fourth fixing member 2236 is adjustable. The first direction x is configured to be perpendicular to the direction of the clamping force exerted by the first fixing component 222 and the second fixing component 223 on the accompanying component 221.

[0129] By making the distance between the first fixing component 222 and the second fixing component 223 in the direction of their clamping force on the accompanying component 221 adjustable, the fixing device 22 can be compatible with lithium batteries 60 under test of different thicknesses. By making the first fixing member 2225 and the second fixing member 2226 slidably connected, and the third fixing member 2235 and the fourth fixing member 2236 slidably connected, the distance between the first assembly 22a and the second assembly 22b in the first direction x can be adjusted, thereby making the fixing device 22 compatible with lithium batteries 60 under test of different heights. In this way, the restraint tray 20 can be compatible with lithium batteries 60 under test of different thicknesses and different heights, improving the compatibility of the restraint tray 20.

[0130] When the fixing device 22 is compatible with lithium batteries 60 of different heights, the accompanying component 221 carrying the lithium battery 60 first enters the space between the first fixing component 222 and the third fixing member 2235, and slides relative to the first assembly 22a. After the accompanying component 221 passes the first assembly 22a, it enters the second assembly 22b and slides relative to the second assembly 22b. When the bottom of the accompanying component 221 abuts against the bottom of the second assembly 22b, since the distance between the first assembly 22a and the second assembly 22b in the first direction x is adjustable, the bottom of the accompanying component 221 pushes the second assembly 22b to slide relative to the first assembly 22a, thereby changing the distance between the entrance of the first assembly 22a and the bottom of the second assembly 22b, thus enabling the fixing device 22 to be compatible with lithium batteries 60 of different heights.

[0131] When the fixing device 22 is compatible with lithium batteries 60 of different heights, the accompanying component 221 carrying the lithium battery 60 first enters the space between the first fixing component 222 and the third fixing member 2235, and slides relative to the first assembly 22a. After the accompanying component 221 passes the first assembly 22a, it enters the second assembly 22b and slides relative to the second assembly 22b. When the bottom of the accompanying component 221 abuts against the bottom of the second assembly 22b, since the distance between the first assembly 22a and the second assembly 22b in the first direction x is adjustable, the bottom of the accompanying component 221 pushes the second assembly 22b to slide relative to the first assembly 22a, thereby changing the distance between the entrance of the first assembly 22a and the bottom of the second assembly 22b, thus enabling the fixing device 22 to be compatible with lithium batteries 60 of different heights.

[0132] In some embodiments of this application, a first tensile elastomer may be provided between the first assembly 22a and the second assembly 22b so that the first assembly 22a and the second assembly 22b always tend to move closer to each other.

[0133] During the process of accommodating lithium batteries 60 of different heights using the fixing device 22, the accompanying component 221 pushes the second assembly 22b to slide relative to the first assembly 22a. At this time, the second assembly 22b overcomes the elastic force of the first tensile elastomer, meaning that under the action of the elastic force of the first tensile elastomer, the second assembly 22b still tends to move closer to the first assembly 22a. After the accompanying component 221 is installed between the first fixing component 222 and the second fixing component 223, the clamping device 23 provides clamping force, causing the first fixing component 222 and the second fixing component 223 to clamp the accompanying component 221. This prevents the first assembly 22a and the second assembly 22b from moving closer to each other due to the elastic force of the first tensile elastomer, thereby improving the reliability of the fixing device 22's compatibility with the lithium battery 60 under test.

[0134] After the accompanying component 221 is removed from between the first fixing component 222 and the second fixing component 223, the second assembly 22b and the first assembly 22a move closer to each other under the action of the first tensile elastomer. This allows the fixing device 22 to be compatible with both large-sized and small-sized lithium batteries under test 60.

[0135] In some embodiments of this application, the first assembly 22a is provided with a snap-fit ​​protrusion, and the accompanying component 221 is provided with a snap-fit ​​groove. The snap-fit ​​protrusion is adapted to the snap-fit ​​groove. When the accompanying component 221 is installed between the first fixing component 222 and the second fixing component 223, the snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0136] After the accompanying component 221 is installed between the first fixing component 222 and the second fixing component 223, the snap-fit ​​protrusion engages with the slot, thereby preventing the accompanying component 221 from sliding relative to the first assembly 22a and ensuring the stability of the position of the accompanying component 221 between the first fixing component 222 and the second fixing component 223. After the accompanying component 221 is installed between the first fixing component 222 and the second fixing component 223, the snap-fit ​​protrusion engages with the slot, thereby limiting the snap-fit ​​protrusion through the inner wall of the slot, preventing the accompanying component 221 from sliding relative to the first assembly 22a, and thus preventing the first assembly 22a and the second assembly 22b from approaching each other due to the elastic force of the first tensile elastic body, thereby improving the reliability of the fixing device 22 in compatibility with the lithium battery 60 under test.

[0137] In some embodiments of this application, the first fixing member 2225 includes a first limiting member 22251 and a second limiting member 22252, which are slidably connected in the second direction y. The second fixing member 2226 includes a third limiting member 22261 and a fourth limiting member 22262, which are slidably connected in the second direction y. The distance between the third assembly 22c formed by the first limiting member 22251 and the third limiting member 22261 and the fourth assembly 22d formed by the second limiting member 22252 and the fourth limiting member 22262 in the second direction y is adjustable. The third fixing member 2235 includes a fifth limiting member 22351 and a sixth limiting member 22352, which are slidably connected in the second direction y. The fourth fixing member 2236 includes a seventh limiting member 22361 and an eighth limiting member 22362, which are slidably connected in the second direction y. The distance between the fifth assembly 22e formed by the fifth limiting member 22351 and the seventh limiting member 22361 and the sixth assembly 2f formed by the sixth limiting member 22352 and the eighth limiting member 22362 in the second direction y is adjustable. The second direction y is configured to be perpendicular to the first direction x and the direction of the clamping force exerted by the first fixing component 222 and the second fixing component 223 on the accompanying component 221.

[0138] By slidingly connecting the first limiting member 22251 and the second limiting member 22252 in the second direction y, and by slidingly connecting the third limiting member 22261 and the fourth limiting member 22262 in the second direction y, the first fixing component 222 can be compatible with lithium batteries 60 of different widths under test. By slidingly connecting the fifth limiting member 22351 and the sixth limiting member 22352 in the second direction y, and by slidingly connecting the seventh limiting member 22361 and the eighth limiting member 22362 in the second direction y, the second fixing component 223 can be compatible with lithium batteries 60 of different widths under test. Furthermore, by making both the first fixing component 222 and the second fixing component 223 compatible with lithium batteries 60 of different widths under test, the fixing device 22 can be compatible with lithium batteries 60 of different widths under test.

[0139] When the fixing device 22 is compatible with lithium batteries 60 of different widths, the accompanying component 221 first reaches between the first fixing member 2225 and the third fixing member 2235, and through the squeezing action, separates the first limiting member 22251 from the second limiting member 22252, and separates the fifth limiting member 22351 from the sixth limiting member 22352, so that the first fixing member 2225 and the third fixing member 2235 can adapt to the width of the lithium battery 60 under test. During the separation of the first limiting member 22251 and the second limiting member 22252, the third limiting member 22261 moves synchronously with the first limiting member 22251, and the fourth limiting member 22262 moves synchronously with the second limiting member 22252. That is, the third assembly 22c and the fourth assembly 22d separate from each other, thereby changing the width of the first fixing component 222 to adapt to lithium batteries 60 of different widths. Similarly, during the separation of the fifth limiting member 22351 and the sixth limiting member 22352, the seventh limiting member 22361 moves synchronously with the fifth limiting member 22351, and the eighth limiting member 22362 moves synchronously with the sixth limiting member 22352. That is, the fifth assembly 22e and the sixth assembly 2f separate from each other, thereby changing the width of the second fixing component 223 to adapt to lithium batteries 60 of different widths. By simultaneously adapting the widths of the first fixing component 222 and the second fixing component 223 to lithium batteries 60 of different widths, the fixing device 22 can be compatible with lithium batteries 60 of different widths.

[0140] It is understandable that if the width and thickness of the lithium battery 60 under test change simultaneously, the width of the first fixing component 222, the width of the second fixing component 223, and the distance between the first fixing component 222 and the second fixing component 223 will all change due to the squeezing action. In this way, the fixing components can be compatible with lithium batteries 60 under test with different thicknesses and widths.

[0141] In some embodiments of this application, a second tensile elastomer may be provided to tend to bring the third assembly 22c and the fourth assembly 22d closer together; a third tensile elastomer may be provided to tend to bring the fifth assembly 22e and the sixth assembly 2f closer together. Thus, the second and third tensile elastomers tend to restore the width of both the first fixing component 222 and the second fixing component 223 to their initial values.

[0142] When the accompanying component 221 is removed from between the first fixing component 222 and the second fixing component 223, the widths of the first fixing component 222 and the second fixing component 223 are restored to their initial values ​​under the action of the second tensile elastomer and the third stretching elastomer; the distance between the first fixing component 222 and the second fixing component 223 is restored to its initial value under the action of the clamping device 23; and the distance between the inlet of the first assembly 22a and the bottom of the second assembly 22b is restored to its initial value under the action of the first tensile elastomer.

[0143] When compatible with lithium batteries 60 of different thicknesses, the accompanying component 221 carrying the lithium battery 60 presses against the first fixing component 222 and the second fixing component 223 to overcome the force of the clamping device 23, thereby changing the distance between the first fixing component 222 and the second fixing component 223, so that the accompanying component 221 can smoothly enter the space between the first fixing component 222 and the second fixing component 223.

[0144] When compatible with lithium batteries 60 of different widths, the accompanying component 221 carrying the lithium battery 60 squeezes the first fixing component 222 and the second fixing component 223 to overcome the force of the second tensile elastomer and the third tensile elastomer, thereby causing the width of the first fixing component 222 and the second fixing component 223 to change simultaneously, so that the accompanying component 221 can smoothly enter the space of the first fixing component 222 and the second fixing component 223.

[0145] When compatible with lithium batteries 60 of different heights, the bottom of the accompanying component 221 carrying the lithium battery 60 presses against the bottom of the second assembly 22b, thereby changing the distance between the inlet of the first assembly 22a and the bottom of the second assembly 22b. This causes the lengths of both the first fixing component 222 and the second fixing component 223 to change in order to accommodate lithium batteries 60 of different heights.

[0146] This allows the fixing device 22 to adapt to changes in at least one of the dimensions of the lithium battery 60 under test, such as height, thickness, or width. Consequently, the restraint tray 20 is compatible with lithium batteries 60 of different sizes. Loading of lithium batteries 60 of different sizes can be achieved through compression without additional adjustment or the need for additional adjustment devices. This simplifies and speeds up the compatibility process of the restraint tray 20 with the lithium battery 60 under test, reduces production costs, and simplifies the manufacturing process. The accompanying component 221 protects the lithium battery 60 under test, preventing it from being deformed or otherwise damaged by compression.

[0147] Please see Figures 5 to 7 In some embodiments of this application, the restraint tray 20 further includes a guide device 26. The guide device 26 guides the first fixing component 222 and the second fixing component 223 from both sides. The guide device 26 includes a first guide member 261, a second guide member 263, a third guide member 265, and a fourth guide member 267. The first guide member 261 is provided with a first guide groove 262. The second guide member 263 is provided with a second guide groove 264, and the first guide member 261 and the second guide member 263 are respectively provided on both sides of the upper part of the first fixing component 2225. The third guide member 265 is provided with a third guide groove 266. The fourth guide member 267 is provided with a fourth guide groove 268, and the third guide member 265 and the fourth guide member 267 are respectively provided on both sides of the lower part of the second fixing component 2226. The first fixing member 2225 has a first ball bearing 224 and a second ball bearing 225 respectively provided on both sides. The first ball bearing 224 is adapted to the first guide groove 262, and the second ball bearing 225 is adapted to the second guide groove 264. The first ball bearing 224 can roll in the first guide groove 262 along the sliding direction of the fixing device 22, and the second ball bearing 225 can roll in the second guide groove 264 along the sliding direction of the fixing device 22. The second fixing member 2226 has a third ball bearing 226 and a fourth ball bearing 227 respectively provided on both sides. The third ball bearing 226 is adapted to the third guide groove 266, and the fourth ball bearing 227 is adapted to the fourth guide groove 268. The third ball bearing 226 can roll in the third guide groove 266 along the sliding direction of the fixing device 22, and the second ball bearing 225 can roll in the second guide groove 264 along the sliding direction of the fixing device 22. The distance between the first guide member 261 and the second guide member 263 in the second direction y is adjustable, as is the distance between the third guide member 265 and the fourth guide member 267 in the second direction y. The distance between the first guide member 261 and the third guide member 265 in the first direction x is adjustable, as is the distance between the second guide member 263 and the fourth guide member 267 in the first direction x.

[0148] The guide device 26 supports and guides the fixing device 22, thereby ensuring the structural stability of the fixing device 22 and making the sliding of the fixing device 22 and its related structures smoother. By making the distance between the first guide member 261 and the second guide member 263 in the second direction y, the distance between the third guide member 265 and the fourth guide member 267 in the second direction y, the distance between the first guide member 261 and the third guide member 265 in the first direction x, and the distance between the second guide member 263 and the fourth guide member 267 in the first direction x, the guide device 26 can adapt to structural changes in the fixing device 22, so that the restraint tray 20 can better accommodate lithium batteries 60 of different models and sizes under test.

[0149] In some embodiments of this application, the restraint tray 20 further includes an inner tray frame 27. At least two support assemblies 21 are installed within the inner tray frame 27, and the inner tray frame 27 is provided with guide strips 271. Each support assembly 21 includes a first guide rail assembly 211 and a second guide rail assembly 212, which are respectively located on both sides of the fixing device 22. The first guide rail assembly 211 guides the first guide member 261 and the third guide member 265 in the first direction x, and the second guide rail assembly 212 guides the second guide member 263 and the fourth guide member 267 in the first direction x. The distance between the first guide rail assembly 211 and the second guide rail assembly 212 in the second direction y is adjustable, and the guide strips 271 guide the first guide rail assembly 211 and the second guide rail assembly 212 in the second direction y.

[0150] The first guide rail assembly 211 and the second guide rail assembly 212 guide the first guide member 261, the third guide member 265, the second guide member 263, and the fourth guide member 267 respectively, thereby making their movement smoother and improving the stability and reliability of the guiding device 26 structure. The guide bar 271 guides the first guide rail assembly 211 and the second guide rail assembly 212, thereby making their movement smoother.

[0151] Please see Figures 6 to 7 In some embodiments of this application, the clamping device 23 includes a pushing assembly 231 and a clamping assembly 232. The pushing assembly 231 provides a pushing force to the fixing device 22 to bring adjacent fixing devices 22 closer together, and to bring the first fixing assembly 222 and the second fixing assembly 223 closer together. The clamping assembly 232 applies a force to the first fixing assembly 222 and the second fixing assembly 223 to bring the first fixing assembly 222 and the second fixing assembly 223 closer together.

[0152] The thrust assembly 231 pushes the fixing device 22, thereby bringing adjacent fixing devices 22 closer together and clamping them tightly. This positions and fixes the fixing device 22, improving the reliability of fixing the lithium battery 60 under test and the positional accuracy of the lithium battery 60 under test in the restraint tray 20. During the process of bringing adjacent fixing devices 22 tightly together, the thrust assembly 231 uses thrust to bring the first fixing component 222 and the second fixing component 223 of the fixing device 22 closer together and clamp the accompanying component 221, further improving the reliability of fixing the lithium battery 60 under test.

[0153] The clamping component 232 applies force to the first fixing component 222 and the second fixing component 223, so that the first fixing component 222 and the second fixing component 223 move closer to each other. After the accompanying component 221 carrying the lithium battery 60 to be tested is loaded between the first fixing component 222 and the second fixing component 223, the first fixing component 222 and the second fixing component 223 can tightly clamp the accompanying component 221, ensuring that the fixing device 22 can reliably fix the lithium battery 60 to be tested.

[0154] In some embodiments of this application, the fixing devices 22 are linearly arranged in the bracket assembly 21, and the thrust assembly 231 includes: an abutment plate 2311, a support plate 2312, an abutment bolt 2313, and a preload spring 2314. The abutment plate 2311 is fixedly installed in the bracket assembly 21 and abuts against the outermost fixing device 22 in the bracket assembly 21. The support plate 2312 is arranged opposite to the abutment plate 2311, and all fixing devices 22 are located between the support plate 2312 and the abutment plate 2311. The support plate 2312 has threaded holes. The abutment bolt 2313 is adapted to the threaded holes and abuts against the outermost fixing device 22 in the bracket assembly 21. Tightening the abutment bolt 2313 adjusts the holding force of the abutment bolt 2313 on the fixing device 22. The preload spring 2314 is sleeved on the abutment bolt 2313. One end of the preload spring 2314 abuts against the fixing device 22, and the other end of the preload spring 2314 abuts against the support plate 2312. The preload spring 2314 applies an elastic thrust to the fixing device 22.

[0155] In the bracket assembly 21, fixing devices 22 are linearly arranged between the abutment plate 2311 and the support plate 2312, with the outermost fixing device 22 abutting against both the abutment plate 2311 and the abutment bolt 2313. Tightening the abutment bolt 2313 provides a pushing force to ensure the fixing devices 22 are tightly pressed together. When the lithium battery 60 to be tested is to be removed from the fixing device 22, the abutment bolt 2313 is loosened, thereby releasing the tight push on the fixing device 22. This releases the clamping of the first fixing component 222 and the second fixing component 223 on the accompanying component 221, allowing the accompanying component 221, which contains the lithium battery 60 to be tested, to be removed from between the first fixing component 222 and the second fixing component 223. A preload spring 2314 provides preload to the fixing devices 22, ensuring that adjacent fixing devices 22 always tend to be tightly pressed together, thereby preventing the fixing devices 22 from wobbling in the bracket assembly 21 and ensuring the stability of the fixing device 22's position.

[0156] In some embodiments of this application, the number of clamping components 232 is equal to the number of fixing devices 22, and each clamping component 232 corresponds one-to-one with each fixing device 22. Each clamping component 232 includes a first clamping plate 2321, a second clamping plate 2322, and a tension spring 2323. The first clamping plate 2321 abuts against a first fixing component 222. The second clamping plate 2322 abuts against a second fixing component 223. The tension spring 2323 applies a spring force to the first clamping plate 2321 and the second clamping plate 2322 to bring them closer together.

[0157] During the clamping process of clamping the first fixing component 222 and the second fixing component 223 in the fixing device 22, the first clamping plate 2321 abuts against the first fixing component 222 and the second clamping plate 2322 against the second fixing component 223, and the tension spring 2323 provides clamping force to the first clamping plate 2321 and the second clamping plate 2322, thereby tightly clamping the first fixing component 222 and the second fixing component 223 between the first clamping plate 2321 and the second clamping plate 2322, so that the first fixing component 222 and the second fixing component 223 always tend to move closer to each other, and ensure the reliability and stability of fixing the lithium battery 60 under test by the fixing device 22.

[0158] In some embodiments of this application, the bracket assembly 21 is provided with a guide rod 213, and all the first clamping plates 2321 and all the second clamping plates 2322 are connected in series with the guide rod 213. All the first clamping plates 2321 and all the second clamping plates 2322 can slide relative to the guide rod 213.

[0159] The guide rod 213 supports and guides the first clamping plate 2321 and the second clamping plate 2322, thereby ensuring the stability and reliability of the clamping assembly 232 structure and making the movement of the first clamping plate 2321 and the second clamping plate 2322 smoother.

[0160] On the other hand, please see Figures 1 to 4 In some embodiments of this application, a capacity testing device 10 is also provided, including a capacity testing device 30, a sorting device 40, and a conveying device 50. The capacity testing device 30 can accommodate at least one restraint tray 20 and perform capacity testing on the lithium batteries 60 to be tested within the restraint tray 20. The sorting device 40 is used to sort the lithium batteries 60 to be tested after the capacity testing is completed. There are at least two conveying devices 50, each conveying different types of lithium batteries 60 to be tested.

[0161] During the capacity testing of the lithium battery 60 under test, the lithium battery 60 is loaded, fixed, and positioned using a restraint tray 20. The restraint tray 20 containing the lithium battery 60 is then placed into the capacity testing device 30, which performs the capacity testing on the lithium battery 60 in the restraint tray 20. During the capacity testing, the capacity testing device 30 transmits test data information about the lithium battery 60 to the processing module 24 via the data port 25, and the processing module 24 stores and processes the data. After the capacity testing device 30 completes testing all the lithium batteries 60 under test in the restraint tray 20, the sorting device 40 sorts the lithium batteries 60 under test according to the test results, placing different categories of lithium batteries 60 under test into corresponding conveying devices 50, which then transport the different categories of lithium batteries 60 under test separately. In this way, the lithium batteries 60 that have completed capacity grading are automatically sorted, reducing the workload of staff and improving the capacity grading efficiency of the capacity grading equipment 10.

[0162] In some embodiments of this application, the occupancy device 10 can simultaneously accommodate multiple restraint trays 20.

[0163] By having the capacity grading equipment 10 perform capacity grading tests on the lithium batteries 60 to be tested in multiple restraint trays 20, the testing and sorting of the lithium batteries 60 to be tested in different restraint trays 20 are carried out alternately, thereby reducing the waiting time of the capacity grading test device 30 and the sorting device 40 and improving the production efficiency of the capacity grading equipment 10.

[0164] Please see Figures 15 to 18In some embodiments of this application, the capacity testing device 30 includes a host module 31 and a testing module 32. The host module 31 controls the capacity testing process and processes the test data. The testing module 32 includes at least two testing components 33, which are electrically connected to the host module 31. The number of testing components 33 is greater than or equal to the number of lithium batteries 60 under test loaded on the restraint tray 20. Each testing component 33 includes an interaction port 34 and a test probe 35. The interaction port 34 is adapted to a data port 25, and the test probe 35 is used to connect with the electrodes of the lithium battery 60 under test so that the capacity testing device 30 can perform a capacity test on the lithium battery 60 under test. Simultaneously, the interaction port 34 connects to the data port 25 while the test probe 35 connects to the electrodes of the lithium battery 60 under test. The host module 31 acquires the capacity testing data of the lithium battery 60 under test through the test probe 35 and transmits the capacity testing data to the processing module 24 through the interaction port 34.

[0165] During the capacity testing process of the capacity testing device 30 on the lithium battery 60 under test, the test probe 35 connects with the electrodes of the lithium battery 60, enabling the capacity testing device 30 to acquire data information about the lithium battery 60 under test, which is then processed by the host module 31. Simultaneously with the connection of the test probe 35 to the electrodes of the lithium battery 60 under test, the interaction port 34 of the test module 32 connects with the data port 25, thereby transmitting the detected data parameters to the processing module 24. The processing module 24 then stores and processes the data information of the lithium battery 60 under test.

[0166] During the testing process, the detected data is transmitted to the processing module 24, thus overlapping the data transmission process with the testing process and improving the production efficiency of the capacity grading device 10. Data transmission between the sorting system and the processing module 24 is achieved through the interface port 34 and the data port 25, enabling the sorting device 40 to classify and sort the lithium batteries under test 60 based on their data. Data transmission via the interface port 34 and the data port 25 effectively ensures the reliability and effectiveness of the data transmission.

[0167] In some embodiments of this application, the capacity testing device 30 is provided with a testing station and a sorting station, and the testing module 32 is disposed at the testing station. The capacity testing device 30 also includes a transfer device 36, which is used to move the restraint tray 20 between the testing station and the sorting station.

[0168] During the capacity testing of the lithium battery 60 to be tested, the restraint tray 20 containing the lithium battery 60 to be tested is placed in the testing station, and the capacity testing device 30 performs the capacity testing on the lithium battery 60 to be tested. After all the lithium batteries 60 to be tested in the restraint tray 20 have been tested, the restraint tray 20 is moved from the testing station to the sorting station by the transfer device 36, so that the sorting device 40 can sort the lithium batteries 60 to be tested that have completed the capacity testing.

[0169] In some embodiments of this application, the sorting device 40 includes: a material picking component 41, a data acquisition component 45, and a moving shaft module 47. The material picking component 41 is used to pick up the lithium battery 60 to be tested from the restraint tray 20. The data acquisition component 45 is used to acquire data information of the lithium battery 60 to be tested. The moving shaft module 47 is used to drive the material picking component 41 and the data acquisition component 45 to move. The moving shaft module 47 can drive the material picking component 41 to move between the capacity testing device 30 and the conveying device 50.

[0170] During the sorting process of the lithium battery 60 to be tested by the sorting device 40, the moving axis module 47 drives the picking component 41 and the data acquisition component 45 to move within a spatial range. After the lithium battery 60 to be tested is completed, the moving axis module 47 drives the picking component 41 and the data acquisition component 45 to move to the lithium battery 60 to be tested. The data acquisition component 45 interfaces with the data port 25 and acquires data information from the processing module 24. At the same time, the picking component 41 grips the accompanying component 221 carrying the target lithium battery 60 to be tested. The control system of the moving axis module 47 drives the picking component 41, which grips the lithium battery 60 to be tested, to move to the target position according to the acquired data information, thereby classifying and sorting the lithium battery 60 to be tested.

[0171] In some embodiments of this application, the data acquisition component 45 includes a probe component 46, which is adapted to the data port 25. When the material handling component 41 clamps the lithium battery 60 to be tested within the restraint tray 20, the probe component 46 engages with the data port 25, enabling the control system of the moving axis module 47 to acquire data information from the lithium battery 60. The control system of the moving axis module 47 then controls the moving axis module 47 based on the data information from the lithium battery 60.

[0172] During the process of data acquisition component 45 acquiring data information from processing module 24, probe component 46 is connected to data port 25 so that control system of moving axis module 47 can acquire data information of lithium battery 60 under test. Control system of moving axis module 47 controls moving axis module 47 according to data information of lithium battery 60 under test, so that sorting device 40 automatically classifies and sorts lithium battery 60 under test according to capacity test results, thereby improving production efficiency of capacity sorting equipment 10.

[0173] On the other hand, in some embodiments of this application, a capacity testing device 10 is also provided, including a capacity testing device 30 and a sorting device 40. The capacity testing device 30 can accommodate at least one restraint tray 20 and perform capacity testing on the lithium battery 60 to be tested within the restraint tray 20. The sorting device 40 is used to sort the lithium battery 60 to be tested after the capacity testing is completed. The sorting device 40 includes a material picking component 41 and a clamping component 42. The material picking component 41 is used to remove the lithium battery 60 to be tested from the restraint tray 20. The clamping component 42 is used to control the opening and closing of the clamping device 23.

[0174] During the capacity grading test of the lithium battery 60, the lithium battery 60 is loaded, fixed, and positioned using a restraint tray 20. The restraint tray 20 containing the lithium battery 60 is then placed into the capacity grading test device 30, where the capacity grading test device 30 performs the capacity grading test on the lithium battery 60 in the restraint tray 20. The sorting device 40 then sorts the lithium batteries 60 according to the test results, separating different categories of lithium batteries 60. In this way, the capacity-graded lithium batteries 60 are automatically sorted, reducing the workload of workers and improving the capacity grading efficiency of the capacity grading equipment 10.

[0175] During the sorting process of the sorting device 40 for the lithium batteries 60 to be tested, the clamping device 23 is opened by the clamping assembly 42, thereby allowing the fixing device 22 to release the accompanying assembly 221 containing the lithium batteries 60 to be tested. After the clamping device 23 is opened, the accompanying assembly 221 containing the lithium batteries 60 to be tested is taken out from the restraint tray 20 by the material picking assembly 41, and the lithium batteries 60 to be tested are classified and sorted according to the capacity test results.

[0176] In some embodiments of this application, the fixing device 22 is linearly arranged in the bracket assembly 21, and the thrust assembly 231 includes: an abutment plate 2311, a support plate 2312, an abutment bolt 2313, and a preload spring 2314. The clamping assembly 42 includes a tightening assembly 43 and a tightening motor 44. The tightening assembly 43 is adapted to the abutment bolt 2313, and the tightening motor 44 drives the tightening assembly 43 to rotate, so that the tightening assembly 43 drives the abutment bolt 2313 to rotate.

[0177] Abutment plate 2311 is fixedly installed on bracket assembly 21, and abuts against the outermost fixing device 22 of bracket assembly 21. Support plate 2312 is positioned opposite to abutment plate 2311, and all fixing devices 22 are located between support plate 2312 and abutment plate 2311. Support plate 2312 has threaded holes. Abutment bolt 2313 is fitted into the threaded holes and abuts against the outermost fixing device 22 of bracket assembly 21. Tightening abutment bolt 2313 adjusts the holding force of abutment bolt 2313 against fixing device 22. Preload spring 2314 is sleeved on abutment bolt 2313, with one end abutting against fixing device 22 and the other end abutting against support plate 2312. Preload spring 2314 applies an elastic thrust to fixing device 22.

[0178] In the bracket assembly 21, fixing devices 22 are linearly arranged between the abutment plate 2311 and the support plate 2312, with the outermost fixing device 22 abutting against both the abutment plate 2311 and the abutment bolt 2313. Tightening the abutment bolt 2313 provides a pushing force to ensure the fixing devices 22 are tightly pressed together. When the lithium battery 60 to be tested is to be removed from the fixing device 22, the abutment bolt 2313 is loosened, thereby releasing the tight push on the fixing device 22. This releases the clamping of the first fixing component 222 and the second fixing component 223 on the accompanying component 221, allowing the accompanying component 221, which contains the lithium battery 60 to be tested, to be removed from between the first fixing component 222 and the second fixing component 223. A preload spring 2314 provides preload to the fixing devices 22, ensuring that adjacent fixing devices 22 always tend to be tightly pressed together, thereby preventing the fixing devices 22 from wobbling in the bracket assembly 21 and ensuring the stability of the fixing device 22's position.

[0179] During the process of opening or closing the clamping assembly 42 on the thrust assembly 231, the screwing assembly 43 is connected to the abutment bolt 2313, and the screwing motor 44 drives the screwing assembly 43 to rotate, thereby adjusting the extension amount of the abutment bolt 2313 at the support plate 2312, thereby adjusting the clamping force of the clamping device 23 on the fixing device 22 or controlling the clamping or releasing of the clamping device 23 on the fixing device 22.
