Description

Technical Field

[0001] The present application relates to the technical field of lithium battery production, and in particular to a compatible lithium battery restraint tray and capacity separation equipment. Background Art

[0002] After the lithium battery has gone through the front-end and middle-end processes to form an unactivated cell, it enters the back-end process. The back-end process of lithium batteries includes packaging, chemical composition, testing and sorting, module assembly and packaging.

[0003] In the production process of lithium batteries, restraint pallets are usually required to load, fix and position the lithium batteries so that they can be processed, sorted, placed and transported.

[0103] See also Figures 5 to 7 In some embodiments of the present application, a restraint tray 20 proposed in the present application includes: a bracket assembly 21, a fixing device 22, a clamping device 23, a processing module 24 and a data port 25. The number of the fixing devices 22 is at least two, and the fixing device 22 is used to fix the lithium battery 60 to be tested. The fixing device 22 is slidably installed on the bracket assembly 21. The clamping device 23 is installed on the bracket assembly 21. The clamping device 23 is used to clamp or release the fixing device 22 to fix the lithium battery 60 to be tested or to enable at least part of the structure of the fixing device 22 to be taken out with the lithium battery 60 to be tested. The processing module 24 is used to store and process relevant data information of the lithium battery 60 to be tested. The processing module 24 is arranged on the fixing device 22 so that the processing module 24 can be taken out with the lithium battery 60 to be tested. The data port 25 is electrically connected to the processing module 24 and is disposed on the fixture 22. The data port 25 is used to exchange data information between the processing module 24 and the outside world. The data port 25 is disposed on the fixture 22 so that the data port 25 can be removed along with the lithium battery 60 under test. During the capacity separation test, the processing module 24 obtains and records the data information.

[0104] During the process of performing a capacity separation test on the lithium battery 60 to be tested, the lithium battery 60 to be tested is loaded, fixed and positioned by the restraining tray 20. By loading multiple lithium batteries 60 to be tested by the restraining tray 20, the capacity separation test can be performed on multiple lithium batteries 60 to be tested at one time, thereby improving the capacity separation efficiency of the lithium battery 60 to be tested. After the lithium battery 60 to be tested is loaded into the restraining tray 20, the lithium battery 60 to be tested is fixed by the fixing device 22, and the fixing device 22 is clamped by the clamping device 23, so that the fixing device 22 is fixed and positioned, thereby improving the position accuracy of the lithium battery 60 to be tested in the restraining tray 20. When the lithium battery 60 to be tested is to be taken out of the restraining tray 20, the lithium battery 60 to be tested is released by the clamping device 23, so that at least part of the structure in the fixing device 22 can be separated from the restraining tray 20 along with the lithium battery 60 to be tested. A processing module 24 and a data port 25 are provided in the fixture 22. When at least a portion of the structure in the fixture 22 is separated from the restraint tray 20 along with the lithium battery 60 to be tested, the processing module 24 and the data port 25 are separated from the restraint tray 20 along with the portion of the structure in the fixture 22 and the lithium battery 60 to be tested. During the capacity separation test of the lithium battery 60 to be tested, the processing module 24 obtains and records data information about the lithium battery 60 to be tested. After the capacity separation test is completed, when an external device removes the lithium battery 60 to be tested from the restraint tray 20, the data information in the processing module 24 is obtained through the data port 25. The lithium battery 60 to be tested after the capacity separation test is completed is classified and placed according to the data information, thereby achieving automatic sorting of the lithium battery 60 to be tested, thereby further improving the capacity separation efficiency of the lithium battery 60 to be tested.

[0105] See also Figures 9 and 10 In some embodiments of the present application, the data port 25 includes a wired port.

[0106] The external device is connected to the wired port through structures such as data plugs and docking contacts, and then exchanges data information with the processing module 24. During the capacity separation test of the lithium battery 60 to be tested, the capacity separation test device 30 is connected to the wired port through structures such as data plugs and docking contacts, and then transmits the test data of the lithium battery 60 to be tested to the processing module 24, and then the data information of the lithium battery 60 to be tested is stored and processed by the processing module 24. After the capacity separation test of all the lithium batteries 60 to be tested in the restraint tray 20 is completed, the lithium batteries 60 to be tested are sorted according to the test results by the sorting device 40. During the sorting process of the lithium batteries 60 to be tested, the sorting device 40 is connected to the wired port through structures such as data plugs and docking contacts, and then reads the data information about the lithium batteries 60 to be tested stored in the processing module 24, and classifies the lithium batteries 60 to be tested according to the data information of the lithium batteries 60 to be tested, and places the lithium batteries 60 to be tested of different categories in different trays. In this way, automatic sorting of the lithium batteries 60 to be tested is achieved, thereby improving the capacity sorting efficiency of the lithium batteries 60 to be tested.

[0107] In some embodiments of the present application, the data port 25 includes a wireless port, wherein the wireless port includes at least one of a Bluetooth interaction port 34 and an NFC interaction port 34 .

[0108] The external device interacts with the wireless port via the wireless interactive port 34, and then exchanges data with the processing module 24. During the capacity separation test of the lithium battery 60 to be tested, the capacity separation test device 30 interacts with the wireless port via the wireless interactive port 34, and then transmits the test data of the lithium battery 60 to the processing module 24. The processing module 24 then stores and processes the data of the lithium battery 60 to be tested. After the capacity separation test is completed for all the lithium batteries 60 to be tested in the restraint tray 20, the lithium batteries 60 to be tested are sorted according to the test results by the sorting device 40. During the sorting process of the lithium batteries 60 to be tested, the sorting device 40 interacts with the wireless port via the wireless interactive port 34, and then reads the data about the lithium batteries 60 to be tested stored in the processing module 24. The sorting device 40 classifies the lithium batteries 60 according to the data of the lithium batteries 60 to be tested, and places the lithium batteries 60 of different categories into different trays. In this way, the lithium batteries 60 to be tested are automatically sorted, and the efficiency of the capacity separation of the lithium batteries 60 to be tested is improved.

[0109] In some embodiments of the present application, the fixing device 22 is further provided with a QR code.

[0110] During the capacity separation test of the lithium battery 60 to be tested, the capacity separation test device 30 obtains specific data information of the lithium battery 60 to be tested by reading the QR code in the fixture 22 that secures the lithium battery 60 to be tested, enters the specific data information of the lithium battery 60 to be tested into the system, and binds the detected data information about the lithium battery 60 to the specific data information of the lithium battery 60 to be tested. After the capacity separation test is completed for all the lithium batteries 60 to be tested in the restraint tray 20, the lithium batteries 60 to be tested are sorted according to the test results by the sorting device 40. During the sorting process of the lithium batteries 60 to be tested, the sorting device 40 reads the QR code in the fixture 22 that secures the lithium battery 60 to be tested, obtains specific data information of the lithium battery 60 to be tested, queries the data information of the lithium battery 60 after the capacity separation test based on the specific data information, and classifies the lithium batteries 60 to be tested according to the data information of the lithium battery 60 to be tested, placing the lithium batteries 60 of different categories in different trays. In this way, automatic sorting of the lithium batteries 60 to be tested is achieved, thereby improving the capacity sorting efficiency of the lithium batteries 60 to be tested.

[0111] In some embodiments of the present application, the fixing device 22 is further provided with an electronic tag that exchanges data information with an external device via wireless communication.

[0112] During the capacity separation test of the lithium battery 60 to be tested, the capacity separation test device 30 writes the detection data information of the lithium battery 60 to be tested into the electronic tag by wireless communication. After the capacity separation test of all the lithium batteries 60 to be tested in the restraint tray 20 is completed, the lithium batteries 60 to be tested are sorted according to the test results by the sorting device 40. During the sorting process of the lithium batteries 60 to be tested, the sorting device 40 reads the data information about the lithium batteries 60 to be tested in the electronic tag by wireless communication, and classifies the lithium batteries 60 to be tested according to the data information of the lithium batteries 60 to be tested, and places the lithium batteries 60 to be tested of different categories in different trays. In this way, the automatic sorting of the lithium batteries 60 to be tested is realized, and the capacity separation efficiency of the lithium batteries 60 to be tested is improved.

The tether assembly 221 is provided with a battery slot 2211 for accommodating and securing the lithium battery 60 under test. The data port 25 is provided on the tether assembly 221. The first fixing assembly 222 is provided with a first fixing slot 2221. The second fixing assembly 223 is slidably connected to the first fixing assembly 222 and provided with a second fixing slot 2231, which is arranged opposite the first fixing slot 2221. When the fixing device 22 secures the lithium battery 60 under test, the lithium battery 60 under test is loaded onto the tether assembly 221. The fixing device 22 clamps the tether assembly 221 between the first fixing assembly 222 and the second fixing assembly 223. One side of the tether assembly 221 is embedded in the first fixing slot 2221, and the other side of the tether assembly 221 is embedded in the second fixing slot 2231. The relative sliding direction between the first fixing assembly 222 and the second fixing assembly 223 is toward the direction of the clamping force exerted by the fixing device 22 on the accompanying assembly 221 .

[0115] During the process of loading and securing the lithium battery 60 to be tested, the securing device 22 loads the lithium battery 60 to be tested onto the accompanying assembly 221, which then protects and preliminarily secures the lithium battery 60 to be tested. After the lithium battery 60 to be tested is loaded into the accompanying assembly 221, the accompanying assembly 221 is inserted between the first securing assembly 222 and the second securing assembly 223, with one side of the accompanying assembly 221 embedded in the first securing groove 2221 and the other side of the accompanying assembly 221 embedded in the second securing groove 2231. The accompanying assembly 221, loaded with the lithium battery 60 to be tested, is then clamped between the first securing assembly 222 and the second securing assembly 223, thereby limiting and securing the accompanying assembly 221 via the sidewalls of the first securing groove 2221 and the second securing groove 2231.

[0116] The lithium battery 60 to be tested is loaded via the accompanying assembly 221 . During the process of transporting, fixing, positioning or processing the single lithium battery 60 to be tested, the accompanying assembly 221 protects the lithium battery 60 to be tested to prevent the lithium battery 60 to be tested from being damaged.

[0117] After the accompanying assembly 221 is moved into position, the first fixing assembly 222 and the second fixing assembly 223, under the force of the clamping device 23, approach each other and clamp the accompanying assembly 221. Different types of lithium batteries 60 to be tested require accompanying assemblies 221 of different sizes. Consequently, after the first fixing assembly 222 and the second fixing assembly 223 clamp the accompanying assembly 221, the distance between the first fixing assembly 222 and the second fixing assembly 223 varies. This allows the first fixing assembly 222 and the second fixing assembly 223 to clamp accompanying assemblies 221 of different sizes, thereby making the restraint tray 20 compatible with different types of lithium batteries 60 to be tested. This improves the compatibility of the restraint tray 20.

[0118] When it is necessary to remove a lithium battery 60 under test individually, the first fixing assembly 222 and the second fixing assembly 223 can maintain a tight grip on the pallet assembly 221, allowing the lithium battery 60 under test to be removed from the pallet assembly 221, leaving the pallet assembly 221 between the first fixing assembly 222 and the second fixing assembly 223. During the process of loading individual lithium batteries 60 under test, the lithium battery 60 under test is placed into the empty pallet assembly 221. At this time, the empty pallet assembly 221 can be fixed to the loading structure of the lithium battery 60 under test and also fixed between the first fixing assembly 222 and the second fixing assembly 223. The pallet assembly 221 protects the lithium battery 60 under test, thereby preventing the lithium battery 60 under test from being clamped and deformed.

[0119] See also Figure 9 In some embodiments of the present application, the processing module 24 and the data port 25 are both provided in the accompanying component 221 .

[0120] By arranging the processing module 24 and the data port 25 in the accompanying component 221, the processing module 24 and the data port 25 can be transported together with the lithium battery to be tested 60, so that data information can be exchanged with the outside world at each stage of processing or testing the lithium battery to be tested 60, which facilitates the processing or testing of the lithium battery to be tested 60.

[0121] In some embodiments of the present application, a QR code and / or an electronic tag is provided on the accompanying component 221 .

[0122] By setting the QR code and / or electronic tag on the accompanying component 221, the QR code and / or electronic tag can be transported along with the lithium battery 60 to be tested, so that data information can be exchanged with the outside world at each stage of processing or testing the lithium battery 60 to be tested, which facilitates the processing or testing of the lithium battery 60 to be tested.

[0123] In some embodiments of the present application, a restraint tray 20 proposed in the present application includes: a bracket assembly 21, a fixing device 22, and a clamping device 23. The fixing device 22 is slidably mounted on the bracket assembly 21, and the fixing device 22 includes an accompanying assembly 221, a first fixing assembly 222, and a second fixing assembly 223. The first fixing assembly 222 and the second fixing assembly 223 are arranged opposite to each other, and the distance between the first fixing assembly 222 and the second fixing assembly 223 is adjustable. The clamping device 23 is mounted on the bracket assembly 21, and the clamping device 23 is used to at least bring the first fixing assembly 222 and the second fixing assembly 223 closer to each other. The inlet side of the first fixing assembly 222 is provided with a first extrusion slope 2222, and the inlet side of the second fixing assembly 223 is provided with a second extrusion slope 2232. The first extrusion slope 2222 and the second extrusion slope 2232 are arranged opposite to each other. A first pressing protrusion 2212 is provided on the side of the accompanying assembly 221 near the first fixing assembly 222, and a second pressing protrusion 2213 is provided on the side of the accompanying assembly 221 near the second fixing assembly 223. When the fixing device 22 is securing the lithium battery 60 to be tested, the lithium battery 60 to be tested is loaded onto the accompanying assembly 221 and enters between the first and second fixing assemblies 222 and 223 from the entrance side of the first and second fixing assemblies 222 and 223. As the accompanying assembly 221 enters between the first and second fixing assemblies 222 and 223, the first pressing protrusion 2212 presses against the first pressing inclined surface 2222, and the second pressing protrusion 2213 presses against the second pressing inclined surface 2232, causing the first and second fixing assemblies 222 and 223 to overcome the force of the clamping device 23 and move away from each other.

[0124] Different models of lithium batteries 60 to be tested have different dimensions. Different accompanying assemblies 221 are designed for different models of lithium batteries 60 to be tested. The accompanying assemblies 221 protect the lithium batteries 60 to be tested, preventing damage to the lithium batteries 60 during transportation and loading. After the accompanying assembly 221 is loaded with the lithium battery 60 to be tested, the accompanying assembly 221 is inserted between the first fixing assembly 222 and the second fixing assembly 223 through the entrance of the fixing device 22. The first squeezing protrusion 2212 and the second squeezing protrusion 2213 respectively squeeze the first squeezing slope 2222 and the second squeezing slope 2232, thereby causing the first fixing assembly 222 and the second fixing assembly 223 to overcome the force of the clamping device 23 and move away from each other, thereby allowing the accompanying assembly 221 loaded with the lithium battery 60 to be tested to smoothly enter between the first fixing assembly 222 and the second fixing assembly 223. After the accompanying assembly 221 is moved into position, the first fixing assembly 222 and the second fixing assembly 223, under the force of the clamping device 23, approach each other and clamp the accompanying assembly 221. Different types of lithium batteries 60 to be tested require accompanying assemblies 221 of different sizes. Consequently, after the first fixing assembly 222 and the second fixing assembly 223 clamp the accompanying assembly 221, the distance between the first fixing assembly 222 and the second fixing assembly 223 varies. This allows the first fixing assembly 222 and the second fixing assembly 223 to clamp accompanying assemblies 221 of different sizes, thereby making the restraint tray 20 compatible with different types of lithium batteries 60 to be tested. This improves the compatibility of the restraint tray 20.

[0125] See also Figures 12 to 14 In some embodiments of the present application, the first extrusion protrusion 2212 and the second extrusion protrusion 2213 are respectively protruded outward on both sides of the accompanying component 221.

[0126] By making the first extrusion protrusion 2212 and the second extrusion protrusion 2213 protrude on both sides of the accompanying component 221 respectively, after the accompanying component 221 enters between the first fixed component 222 and the second fixed component 223, the first extrusion protrusion 2212 and the second extrusion protrusion 2213 respectively contact the inner wall of the first fixed component 222 and the inner wall of the second fixed component 223, thereby avoiding the side wall of the accompanying component 221 from contacting the inner walls of the first fixed component 222 and the second fixed component 223, thereby reducing the contact area between the accompanying component 221 and the first fixed component 222 and the second fixed component 223, thereby reducing the friction resistance when the accompanying component 221 slides relative to the first fixed component 222 and the second fixed component 223, making the process of the accompanying component 221 entering between the first fixed component 222 and the second fixed component 223 smoother.

[0127] In some embodiments of the present application, the restraint tray 20 further includes a guide device 26. The guide device 26 guides the fixing device 22 from both sides thereof. The first fixing assembly 222 and the second fixing assembly 223 are both guided by the guide device 26.

[0128] As the first fixing assembly 222 and the second fixing assembly 223 move toward or away from each other, the guide device 26 guides the first fixing assembly 222 and the second fixing assembly 223, thereby making the sliding process of the first fixing assembly 222 and the second fixing assembly 223 smoother. The guide device 26 also limits the first fixing assembly 222 and the second fixing assembly 223 so that the first fixing assembly 222 and the second fixing assembly 223 can only move along the direction of the guide device 26, thereby improving the reliability of the restraint tray 20 in positioning the lithium battery 60 to be tested.

[0129] In some embodiments of the present application, the guide 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 provided on either side of the fixing device 22. A first ball member 224 and a second ball member 225 are respectively provided on either side of the fixing device 22. The first ball member 224 is adapted to fit within the first guide groove 262, and the second ball member 225 is adapted to fit within the second guide groove 264. The first ball member 224 can roll within the first guide groove 262 along the sliding direction of the fixing device 22, and the second ball member 225 can roll within the second guide groove 264 along the sliding direction of the fixing device 22.

[0130] A first ball bearing 224 and a second ball bearing 225 are mounted on either side of the fixture 22, respectively. Both the first ball bearing 224 and the second ball bearing 225 can roll relative to the fixture 22. As the fixture 22 slides relative to the bracket assembly 21, the first guide member 261 and the second guide member 263 guide the fixture 22 from either side, thereby ensuring the stability of the fixture 22 during its sliding motion. As the first guide member 261 and the second guide member 263 guide the fixture 22, the first ball bearing 224 rolls within the first guide groove 262, and the second ball bearing 225 rolls within the second guide groove 264. As the guide member 26 guides the fixture 22, the friction between the fixture 22 and the guide member 26 becomes rolling friction, thereby reducing resistance during the sliding of the fixture 22 and facilitating a smoother sliding motion. The guide device 26 limits the position of the first ball member 224 via the first guide member 261, and limits the position of the second ball member 225 via the second guide member 263, thereby limiting the position of the fixing device 22 and preventing the fixing device 22 from moving within the bracket assembly 21. During the process of fixing the fixing device 22 by the clamping device 23, the accompanying assembly 221 is clamped between the first fixing assembly 222 and the second fixing assembly 223. The clamping device 23 provides a clamping force or thrust, thereby bringing the first fixing assembly 222 and the second fixing assembly 223 closer together and tightly clamping the lithium battery 60 under test. The first fixing assembly 222 and the second fixing assembly 223 can both slide relative to the bracket assembly 21 under the guidance of the guide device 26, thereby making the distance between the first fixing assembly 222 and the second fixing assembly 223 adjustable, thereby making the fixing device 22 compatible with lithium batteries 60 under test of different thicknesses. However, by enabling the fixture 22 to slide relative to the bracket assembly 21, the distance between adjacent fixtures 22 is adjustable, thereby providing sufficient space between the fixtures 22 to accommodate lithium batteries 60 of varying thicknesses. When all fixtures 22 are loaded with lithium batteries 60 to be tested, the clamping device 23 provides thrust, causing adjacent fixtures 22 to abut and squeeze each other, thereby further clamping the lithium batteries 60 to be tested and allowing the fixtures 22 to remain stably in the desired position, thereby ensuring the positional accuracy of the lithium batteries 60 to be tested in the restraint tray 20. The guide device 26 allows the first fixture assembly 222, the second fixture assembly 223, and the entire fixture 22 to slide more smoothly by rolling balls in the guide grooves. By installing balls in the fixture 22, the guiding process during the movement of the fixture 22 is ensured to be carried out on a continuous and smooth track, thereby ensuring the continuity and stability of the sliding of the fixture 22. It is understandable that if the balls are mounted on the guide device 26 , the fixing device 22 may vibrate or become stuck when passing adjacent balls.If the balls are not installed, the friction between the fixing device 22 and the guide device 26 will be sliding friction, thereby increasing the resistance of the fixing device 22 during sliding and increasing the risk of the fixing device 22 being stuck during sliding.

[0131] See also Figures 7 to 12 In some embodiments of the present application, the first fixing assembly 222 includes a first fixing member 2225 and a first opening guide member 2224, wherein the first fixing member 2225 is detachably connected to the first opening guide member 2224. The first fixing member 2225 is provided with a first ball rolling groove, and the first opening guide member 2224 is provided with a second ball rolling groove. The first ball rolling groove and the second ball rolling groove are arranged opposite each other, and both the first ball rolling groove and the second ball rolling groove are adapted to fit the first ball rolling member 224. The first ball rolling member 224 is rollably mounted in the first and second ball rolling grooves. The first ball rolling member 224 is exposed in the first ball rolling groove on a side away from the second ball rolling groove, and the first ball rolling member 224 is exposed in the second ball rolling groove on a side away from the first ball rolling groove, thereby enabling the first ball rolling member 224 to contact an external structure and roll. The second fixing assembly 223 includes a second fixing member 2226 and a second opening guide member 2234, wherein the second fixing member 2226 is detachably connected to the second opening guide member 2234. The second fixing member 2226 is provided with a third ball rolling groove, and the second open guide member 2234 is provided with a fourth ball rolling groove. The third ball rolling groove and the fourth ball rolling groove are arranged opposite each other. The third and fourth ball rolling grooves are adapted to fit the second ball rolling member 225. The second ball rolling member 225 is rollably mounted in the third and fourth ball rolling grooves. The second ball rolling member 225 is exposed in the third ball rolling groove on the side away from the fourth ball rolling groove, and the second ball rolling member 225 is exposed in the fourth ball rolling groove on the side away from the third ball rolling groove, thereby enabling the second ball rolling member 225 to contact external structures and cause rolling.

[0132] The first ball member 224 is rollably mounted between the first fixing member 2225 and the first open guide member 2224, and is limited and positioned by the first fixing member 2225 and the first open guide member 2224. This allows the first ball member 224 to move with the first fixing assembly 222 and to roll relative to the first fixing assembly 222. The second ball member 225 is rollably mounted between the second fixing member 2226 and the second open guide member 2234, and is limited and positioned by the second fixing member 2226 and the second open guide member 2234. This allows the second ball member 225 to move with the second fixing assembly 223 and to roll relative to the second fixing assembly 223. Thus, during the process of the guide device 26 guiding the fixing device 22, the first ball member 224 rolls in the first guide groove 262 of the first guide member 261, and the second ball member 225 rolls in the second guide groove 264 of the second guide member 263. The first ball member 224 can be disassembled and assembled by detaching the first opening guide member 2224 from or attaching it to the first fixing member 2225; the second ball member 225 can be disassembled and assembled by detaching the second opening guide member 2234 from or attaching it to the second fixing member 2226. This facilitates replacement or maintenance of the first ball member 224 and the second ball member 225.

[0133] In some embodiments of the present application, the first opening guide 2224 is located on the inlet side of the first fixed component 222, and the first opening guide 2224 is provided with a first extrusion slope 2222, and the first extrusion slope 2222 extends from the outer side of the first fixed component 222 to the inner side of the first fixed component 222; the second opening guide 2234 is located on the inlet side of the second fixed component 223, and the second opening guide 2234 is provided with a second extrusion slope 2232, and the second extrusion slope 2232 extends from the outer side of the second fixed component 223 to the inner side of the second fixed component 223.

[0134] When the accompanying assembly 221, loaded with the lithium battery 60 to be tested, is placed between the first and second fixing assemblies 222 and 223, the bottom of the accompanying assembly 221 simultaneously compresses the first and second compressing slopes 2222 and 2232, thereby separating the first and second fixing assemblies 222 and 223, allowing the accompanying assembly 221 to smoothly enter between the first and second fixing assemblies 222 and 223. Lithium batteries 60 to be tested of varying thicknesses can be accommodated by accompanying assemblies 221 of varying sizes. When accompanying assemblies 221 of varying sizes are pressed against the first and second compressing slopes 2222 and 2232, the distances separating the first and second fixing assemblies 222 and 223 differ. This allows the fixture 22 to automatically adapt to lithium batteries 60 to be tested of varying thicknesses, improving the compatibility of the restraint tray 20.

[0135] In some embodiments of the present application, a first limiting groove 2223 is provided at the bottom of the first fixing assembly 222, and a second limiting groove 2233 is provided at the bottom of the second fixing assembly 223. After the accompanying assembly 221 enters between the first fixing assembly 222 and the second fixing assembly 223, the first extrusion protrusion 2212 enters the first limiting groove 2223, and the second extrusion protrusion 2213 enters the second limiting groove 2233, so that the first fixing assembly 222 and the second fixing assembly 223 are moved closer to each other under the action of the clamping device 23.

[0136] In the process of the accompanying component 221 entering between the first fixed component 222 and the second fixed component 223, the first extrusion protrusion 2212 squeezes the first extrusion inclined surface 2222, and the second extrusion protrusion 2213 squeezes the second extrusion inclined surface 2232, thereby separating the first fixed component 222 and the second fixed component 223 from each other, and allowing the accompanying component 221 to smoothly enter between the first fixed component 222 and the second fixed component 223.

[0137] When the first extrusion protrusion 2212 and the second extrusion protrusion 2213 respectively pass over the first extrusion inclined surface 2222 and the second extrusion inclined surface 2232, the first extrusion protrusion 2212 contacts the inner wall of the first fixed component 222 and protrudes between the accompanying component 221 and the first fixed component 222, avoiding the inner wall of the first fixed 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 fixed component 223 and protrudes between the accompanying component 221 and the second fixed component 223, avoiding the inner wall of the second fixed 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 accompanying component 221 does not contact the inner walls of the first fixed component 222 and the second fixed component 223, thereby reducing the contact area between the accompanying component 221 and the first fixed component 222 and the second fixed component 223, thereby reducing the friction resistance when the accompanying component 221 slides relative to the first fixed component 222 and the second fixed component 223, making the process of the accompanying component 221 entering between the first fixed component 222 and the second fixed component 223 smoother.

[0138] When the first extrusion protrusion 2212 and the second extrusion protrusion 2213 respectively pass over the inner walls of the first fixing component 222 and the second fixing component 223, 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 by the inner walls of the first limiting groove 2223 and the inner walls of 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 are respectively in contact with the side walls on both sides of the accompanying component 221, and the first fixing component 222 and the second fixing component 223 tightly clamp the accompanying component 221 to prevent the accompanying component 221 from being separated from between the first fixing component 222 and the second fixing component 223, so that 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 pointed out that the size of the accompanying component 221 is specifically designed according to the different models of the lithium battery 60 to be tested, so that the lithium battery 60 to be tested can be stably and reliably loaded in the accompanying component 221. After the lithium battery 60 to be tested is loaded into the accompanying component 221, the lithium battery 60 to be tested is limited and positioned by the inner wall of the accompanying component 221, thereby ensuring the position accuracy of the lithium battery 60 to be tested.

[0139] When the lithium battery 60 to be tested needs to be removed from the fixture 22, the accompanying assembly 221 can be clamped by an external material removal device, and the lithium battery 60 to be tested and the accompanying assembly 221 can be removed together. By clamping the accompanying assembly 221 to remove the lithium battery 60 to be tested from the fixture 22, the lithium battery 60 to be tested is removed, thereby avoiding direct clamping of the lithium battery 60 to be tested. The accompanying assembly 221 protects the lithium battery 60 to be tested, reducing the risk of damage to the lithium battery 60 to be tested.

[0140] During the process of taking out the accompanying component 221, the first extrusion protrusion 2212 and the second extrusion protrusion 2213 respectively squeeze the inner walls of the first limiting groove 2223 and the second limiting groove 2233, thereby separating the first fixing component 222 and the second fixing component 223 from each other, so that the first extrusion protrusion 2212 and the second extrusion protrusion 2213 can smoothly enter between the inner walls of the first fixing component 222 and the second fixing component 223, and can slide relative to the inner walls of the first fixing component 222 and the second fixing component 223 until the accompanying component 221 is separated from the space between the first fixing component 222 and the second fixing component 223, thereby realizing the removal of the accompanying component 221.

[0141] In some embodiments of the present application, the first fixing assembly 222 includes a first fixing member 2225 and a second fixing member 2226, and the second fixing assembly 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 each other, and the second fixing member 2226 and the fourth fixing member 2236 are disposed opposite 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 a first assembly 22a formed by the first fixing member 2225 and the third fixing member 2235 and a second assembly 22b formed by the second fixing member 2226 and the fourth fixing member 2236 is adjustable. The first direction x is perpendicular to the direction of the clamping force exerted by the first fixing assembly 222 and the second fixing assembly 223 on the accompanying assembly 221.

[0142] By making the distance between the first fixing assembly 222 and the second fixing assembly 223 adjustable in the direction of their clamping force on the accompanying assembly 221, the fixing device 22 is compatible with lithium batteries 60 under test of varying thicknesses. By making the first fixing member 2225 slidably connected to the second fixing member 2226, and the third fixing member 2235 slidably connected to the fourth fixing member 2236, the distance between the first assembly 22a and the second assembly 22b in the first direction x is adjustable, thereby making the fixing device 22 compatible with lithium batteries 60 under test of varying heights. This makes the restraint tray 20 compatible with lithium batteries 60 under test of varying thicknesses and heights, improving the compatibility of the restraint tray 20.

[0143] When the fixture 22 is compatible with lithium batteries 60 to be tested of different heights, the accompanying assembly 221 loaded with the lithium battery 60 to be tested first enters the space between the first fixing assembly 222 and the third fixing member 2235 and slides relative to the first assembly 22a. After passing through the first assembly 22a, the accompanying assembly 221 enters the second assembly 22b and slides relative to the second assembly 22b. When the bottom of the accompanying assembly 221 abuts the bottom of the second assembly 22b, the distance between the first assembly 22a and the second assembly 22b in the first direction x is adjustable. The bottom of the accompanying assembly 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, thereby making the fixture 22 compatible with lithium batteries 60 to be tested of different heights.

[0144] When the fixture 22 is compatible with lithium batteries 60 to be tested of different heights, the accompanying assembly 221 loaded with the lithium battery 60 to be tested first enters the space between the first fixing assembly 222 and the third fixing member 2235 and slides relative to the first assembly 22a. After passing through the first assembly 22a, the accompanying assembly 221 enters the second assembly 22b and slides relative to the second assembly 22b. When the bottom of the accompanying assembly 221 abuts the bottom of the second assembly 22b, the distance between the first assembly 22a and the second assembly 22b in the first direction x is adjustable. The bottom of the accompanying assembly 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, thereby making the fixture 22 compatible with lithium batteries 60 to be tested of different heights.

[0145] In some embodiments of the present application, a first tensile elastic body may be disposed between the first assembly body 22a and the second assembly body 22b, so that the first assembly body 22a and the second assembly body 22b always tend to approach each other.

[0146] During the process of the fixture 22 being compatible with the lithium batteries 60 under test of different heights, the accompanying assembly 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 elastic body. That is, under the elastic force of the first tensile elastic body, the second assembly 22b still tends to move closer to the first assembly 22a. After the accompanying assembly 221 is installed in place between the first fixing assembly 222 and the second fixing assembly 223, the clamping device 23 provides a clamping force, causing the first fixing assembly 222 and the second fixing assembly 223 to clamp the accompanying assembly 221, thereby preventing the first assembly 22a and the second assembly 22b from moving closer together due to the elastic force of the first tensile elastic body, thereby improving the reliability of the fixture 22's compatibility with the lithium batteries 60 under test.

[0147] After the accompanying assembly 221 is removed from between the first fixing assembly 222 and the second fixing assembly 223, the second assembly 22b and the first assembly 22a are moved closer together under the action of the first stretching elastic body. This allows the fixing device 22 to be compatible with both large and small lithium batteries 60 under test.

[0148] In some embodiments of the present application, the first assembly 22a is provided with a snap-in protrusion, and the accompanying component 221 is provided with a snap-in slot. The snap-in protrusion is adapted to the snap-in slot. When the accompanying component 221 is installed in place between the first fixing component 222 and the second fixing component 223, the snap-in protrusion is snapped into the snap-in slot.

[0149] When the accompanying assembly 221 is properly installed between the first fixing assembly 222 and the second fixing assembly 223, the engaging protrusion engages with the engaging groove, thereby preventing the accompanying assembly 221 from sliding relative to the first assembly 22a, thereby ensuring the stability of the position of the accompanying assembly 221 between the first fixing assembly 222 and the second fixing assembly 223. When the accompanying assembly 221 is properly installed between the first fixing assembly 222 and the second fixing assembly 223, the engaging protrusion engages with the engaging groove, thereby limiting the engaging protrusion through the inner wall of the engaging groove, preventing the accompanying assembly 221 from sliding relative to the first assembly 22a, thereby 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's compatibility with the lithium battery 60 to be tested.

[0150] In some embodiments of the present application, the first fixing member 2225 includes a first limiting member 22251 and a second limiting member 22252, the first limiting member 22251 and the second limiting member 22252 being slidably connected in the second direction y. The second fixing member 2226 includes a third limiting member 22261 and a fourth limiting member 22262, the third limiting member 22261 and the fourth limiting member 22262 being 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, the fifth limiting member 22351 and the sixth limiting member 22352 being 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 to each other 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 perpendicular to the first direction x and the direction of the clamping force exerted by the first fixing assembly 222 and the second fixing assembly 223 on the accompanying assembly 221.

[0151] By slidably connecting the first limiting member 22251 and the second limiting member 22252 in the second direction y, and by slidably connecting the third limiting member 22261 and the fourth limiting member 22262 in the second direction y, the first fixing assembly 222 is compatible with lithium batteries 60 under test of different widths. By slidably connecting the fifth limiting member 22351 and the sixth limiting member 22352 in the second direction y, and by slidably connecting the seventh limiting member 22361 and the eighth limiting member 22362 in the second direction y, the second fixing assembly 223 is compatible with lithium batteries 60 under test of different widths. Furthermore, by enabling both the first fixing assembly 222 and the second fixing assembly 223 to be compatible with lithium batteries 60 under test of different widths, the fixing device 22 is also compatible with lithium batteries 60 under test of different widths.

[0152] When the fixing device 22 is compatible with lithium batteries 60 to be tested 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 and the second limiting member 22252 from each other, and separates the fifth limiting member 22351 and the sixth limiting member 22352 from each other, so that the first fixing member 2225 and the third fixing member 2235 can adapt to the width of the lithium battery 60 to be tested. During the process of separation between 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 assembly 222 to accommodate lithium batteries 60 under test of different widths; similarly, during the process of separation between 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 22f separate from each other, thereby changing the width of the second fixing assembly 223 to accommodate lithium batteries 60 under test of different widths. By making the widths of the first fixing component 222 and the second fixing component 223 adapt to the lithium batteries 60 to be tested of different widths, the fixing device 22 can be compatible with the lithium batteries 60 to be tested of different widths.

[0153] It is understandable that if the width and thickness of the lithium battery 60 to be tested change at the same time, 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 through the extrusion effect. In this way, the fixing component can be compatible with lithium batteries 60 to be tested of different thicknesses and different widths.

[0154] In some embodiments of the present application, a second elastic stretching member may be provided to cause the third assembly 22c and the fourth assembly 22d to move closer together; and a third elastic stretching member may be provided to cause the fifth assembly 22e and the sixth assembly 2f to move closer together. Thus, the second and third elastic stretching members can help the widths of the first fixing member 222 and the second fixing member 223 to return to their initial values.

[0155] 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 stretching elastic body and the third pulling elastic body; 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; the distance between the entrance 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 stretching elastic body.

[0156] When compatible with lithium batteries 60 to be tested of different thicknesses, the accompanying component 221 loaded with the lithium battery 60 to be tested squeezes 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.

[0157] When compatible with lithium batteries 60 to be tested of different widths, the accompanying component 221 loaded with the lithium battery 60 to be tested squeezes the first fixing component 222 and the second fixing component 223 to overcome the forces of the second tensile elastic body and the third tensile elastic body, thereby causing the widths 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 between the first fixing component 222 and the second fixing component 223.

[0158] When compatible with lithium batteries 60 to be tested of different heights, the bottom of the accompanying component 221 loaded with the lithium battery 60 to be tested squeezes the bottom of the second assembly 22b, thereby changing the distance between the entrance of the first assembly 22a and the bottom of the second assembly 22b, even if the lengths of the first fixing component 222 and the second fixing component 223 are changed to adapt to lithium batteries 60 to be tested of different heights.

[0159] In this way, the fixing device 22 can adapt to changes in at least one of the height, thickness, or width of the lithium battery 60 to be tested. This allows the restraint tray 20 to be compatible with lithium batteries 60 to be tested of different models and sizes. The loading of lithium batteries 60 to be tested of different sizes can be achieved through the extrusion effect without the need for additional adjustment actions or the addition of adjustment devices, making the compatibility process of the restraint tray 20 with the lithium batteries to be tested 60 simpler and faster, and reducing the production cost of the restraint tray 20 and simplifying the production process of the restraint tray 20. The lithium battery 60 to be tested is protected by the accompanying component 221, thereby preventing the lithium battery 60 to be tested from being squeezed, deformed, or otherwise damaged.

[0160] See also Figures 5 to 7 In some embodiments of the present 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 of the first fixing component 222 and the second fixing component 223. 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. The first guide member 261 and the second guide member 263 are respectively provided on both sides of the upper portion 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. The third guide member 265 and the fourth guide member 267 are respectively provided on both sides of the lower portion of the second fixing component 2226. A first rolling ball 224 and a second rolling ball 225 are provided on either side of the first fixing member 2225. The first rolling ball 224 fits in the first guide groove 262, and the second rolling ball 225 fits in the second guide groove 264. The first rolling ball 224 can roll in the first guide groove 262 along the sliding direction of the fixing device 22, and the second rolling ball 225 can roll in the second guide groove 264 along the sliding direction of the fixing device 22. A third rolling ball 226 and a fourth rolling ball 227 are provided on either side of the second fixing member 2226. The third rolling ball 226 fits in the third guide groove 266, and the fourth rolling ball 227 fits in the fourth guide groove 268. The third rolling ball 226 can roll in the third guide groove 266 along the sliding direction of the fixing device 22, and the second rolling ball 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, and the distance between the third guide member 265 and the fourth guide member 267 in the second direction y is adjustable. The distance between the first guide member 261 and the third guide member 265 in the first direction x is adjustable, and the distance between the second guide member 263 and the fourth guide member 267 in the first direction x is adjustable.

[0161] The guide device 26 supports and guides the fixture 22, thereby ensuring the structural stability of the fixture 22 and enabling smoother sliding of the fixture 22 and its associated structures. By making the distance between the first guide member 261 and the second guide member 263 in the second direction y adjustable, the distance between the third guide member 265 and the fourth guide member 267 in the second direction y adjustable, the distance between the first guide member 261 and the third guide member 265 in the first direction x adjustable, and the distance between the second guide member 263 and the fourth guide member 267 in the first direction x adjustable, the guide device 26 can adapt to structural changes in the fixture 22, thereby making the restraint tray 20 more compatible with lithium batteries 60 of different models and sizes to be tested.

[0162] In some embodiments of the present application, the restraint tray 20 further includes: a tray inner frame 27. At least two bracket assemblies 21 are installed in the tray inner frame 27, and the tray inner frame 27 is provided with a guide bar 271. The bracket assembly 21 includes a first guide rail assembly 211 and a second guide rail assembly 212, and the guide rail assemblies are respectively located on both sides of the fixing device 22. The first guide rail assembly 211 is used to guide the first guide member 261 and the third guide member 265 in the first direction x, and the second guide rail assembly 212 is used to guide 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 bar 271 is used to guide the first guide rail assembly 211 and the second guide rail assembly 212 in the second direction y.

[0163] 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 the first guide member 261, the third guide member 265, the second guide member 263, and the fourth guide member 267 move more smoothly, thereby improving the stability and reliability of the structure of the guide device 26. The first guide rail assembly 211 and the second guide rail assembly 212 are guided by the guide bar 271, thereby making the first guide rail assembly 211 and the second guide rail assembly 212 move more smoothly.

[0164] See also Figures 6 and 7 In some embodiments of the present application, the clamping device 23 includes a thrust assembly 231 and a clamping assembly 232. The thrust assembly 231 is used to provide a thrust to the fixture 22, thereby bringing adjacent fixtures 22 closer together, and the first fixture assembly 222 and the second fixture assembly 223 closer together. The clamping assembly 232 applies a force to the first fixture assembly 222 and the second fixture assembly 223, thereby bringing the first fixture assembly 222 and the second fixture assembly 223 closer together.

[0165] The thrust assembly 231 pushes the fixtures 22, thereby bringing adjacent fixtures 22 closer together and into close contact, thereby positioning and securing the fixtures 22. This improves the reliability of the fixtures 22 in securing the lithium battery 60 to be tested, and also improves the positional accuracy of the lithium battery 60 to be tested within the restraint tray 20. In the process of bringing adjacent fixtures 22 into close contact, the thrust assembly 231 uses the force to bring the first and second fixture assemblies 222 and 223 of the fixtures 22 closer together, and tightly clamps the accompanying assembly 221, further improving the reliability of the fixtures 22 in securing the lithium battery 60 to be tested.

[0166] The clamping assembly 232 applies a force to the first fixing assembly 222 and the second fixing assembly 223 so that the first fixing assembly 222 and the second fixing assembly 223 are close to each other, and then the accompanying assembly 221 loaded with the lithium battery 60 to be tested is loaded between the first fixing assembly 222 and the second fixing assembly 223. The first fixing assembly 222 and the second fixing assembly 223 can tightly clamp the accompanying assembly 221, ensuring that the fixing device 22 can reliably fix the lithium battery 60 to be tested.

[0167] In some embodiments of the present 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 abutment plate 2311 is fixedly mounted on the bracket assembly 21, and abuts against the outermost fixing device 22 in the bracket assembly 21. The support plate 2312 and the abutment plate 2311 are arranged opposite each other, and all the fixing devices 22 are located between the support plate 2312 and the abutment plate 2311. The support plate 2312 is provided with a threaded hole. The abutment bolt 2313 is adapted to the threaded hole and abuts against the outermost fixing device 22 in the bracket assembly 21. Turning the abutment bolt 2313 adjusts the abutment force of the abutment bolt 2313 on the fixing device 22. The preload spring 2314 is sleeved on the abutting 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 elastic thrust to the fixing device 22 .

[0168] In the bracket assembly 21, the fixtures 22 are linearly arranged between the abutment plate 2311 and the support plate 2312, with the outermost fixtures 22 respectively abutting the abutment plate 2311 and the abutment bolts 2313. Tightening the abutment bolts 2313 provides thrust to maintain the fixtures 22 in close contact with each other. To remove the lithium battery 60 to be tested from the fixture 22, the abutment bolts 2313 are loosened, thereby releasing the tight push on the fixture 22, allowing the first and second fixture assemblies 222, 223 in the fixture 22 to release their tight grip on the accompanying assembly 221, allowing the accompanying assembly 221 loaded with the lithium battery 60 to be tested to be removed from between the first and second fixture assemblies 222, 223. Preload springs 2314 provide preload to the fixtures 22, ensuring that adjacent fixtures 22 are always in close contact with each other, thereby preventing the fixtures 22 from shaking in the bracket assembly 21 and ensuring the stability of the fixtures 22's position.

[0169] In some embodiments of the present application, the number of clamping assemblies 232 is equal to the number of fixing devices 22, and each clamping assembly 232 corresponds to each fixing device 22. The clamping assemblies 232 include a first clamping plate 2321, a second clamping plate 2322, and a tension spring 2323. The first clamping plate 2321 abuts the first fixing assembly 222. The second clamping plate 2322 abuts the second fixing assembly 223. The tension spring 2323 applies an elastic force to the first clamping plate 2321 and the second clamping plate 2322, thereby forcing the first clamping plate 2321 and the second clamping plate 2322 toward each other.

[0170] When the clamping assembly 232 clamps the first fixing assembly 222 and the second fixing assembly 223 in the fixing device 22, the first clamping plate 2321 abuts against the first fixing assembly 222, and the second clamping plate 2322 abuts against the second fixing assembly 223, and provides a clamping force to the first clamping plate 2321 and the second clamping plate 2322 through the tension spring 2323, thereby tightly clamping the first fixing assembly 222 and the second fixing assembly 223 between the first clamping plate 2321 and the second clamping plate 2322, so that the first fixing assembly 222 and the second fixing assembly 223 always tend to approach each other, and ensure the reliability and stability of the fixing device 22 in fixing the lithium battery 60 to be tested.

[0171] In some embodiments of the present application, the bracket assembly 21 is provided with a guide rod 213, all the first clamping plates 2321 and all the second clamping plates 2322 are connected in series to the guide rod 213, and all the first clamping plates 2321 and all the second clamping plates 2322 can slide relative to the guide rod 213.

[0172] The first clamping plate 2321 and the second clamping plate 2322 are supported and guided by the guide rod 213, thereby ensuring the stability and reliability of the clamping assembly 232 structure and making the first clamping plate 2321 and the second clamping plate 2322 move more smoothly.

[0173] On the other hand, see Figures 1 to 4 In some embodiments of the present application, the present application further provides a capacity separation device 10, comprising: a capacity separation test device 30, a sorting device 40, and a conveying device 50. The capacity separation test device 30 can accommodate at least one restraint tray 20 and perform a capacity separation test on the lithium batteries 60 to be tested in the restraint tray 20. The sorting device 40 is used to sort the lithium batteries 60 to be tested that have completed the capacity separation test. There are at least two conveying devices 50, and each conveying device 50 conveys different categories of lithium batteries 60 to be tested.

[0174] During the capacity separation test of the lithium battery 60 to be tested, the lithium battery 60 to be tested is loaded, fixed and positioned by the restraint tray 20. The restraint tray 20 loaded with the lithium battery 60 to be tested is placed in the capacity separation test device 30, and the capacity separation test is performed on the lithium battery 60 to be tested in the restraint tray 20 by the capacity separation test device 30. During the capacity separation test of the lithium battery 60 to be tested, the capacity separation test device 30 transmits test data information about the lithium battery 60 to be tested to the processing module 24 through the data port 25, and the data information is stored and processed by the processing module 24. After the capacity separation test device 30 completes the test on all the lithium batteries 60 to be tested in the restraint tray 20, the lithium batteries 60 to be tested are sorted by the sorting device 40 according to the test results, and the lithium batteries 60 to be tested of different categories are placed on the corresponding conveying devices 50 respectively, and then the lithium batteries 60 to be tested of different categories are respectively conveyed by different conveying devices 50. In this way, the lithium batteries 60 to be tested that have been sorted are automatically sorted, which reduces the workload of the staff and improves the sorting efficiency of the sorting device 10 .

[0175] In some embodiments of the present application, the capacity dividing device 10 can accommodate multiple restraint trays 20 at the same time.

[0176] By having the capacity sorting device 10 perform capacity sorting tests on the lithium batteries 60 to be tested in the plurality of restraint trays 20, the testing and sorting of the lithium batteries 60 to be tested in different restraint trays 20 are performed alternately, thereby reducing the waiting time of the capacity sorting test device 30 and the sorting device 40, and improving the production efficiency of the capacity sorting device 10.

[0177] See also Figures 15 to 18In some embodiments of the present application, the capacity separation test device 30 includes: a host module 31 and a test module 32. The host module 31 is used to control the capacity separation test process and process the test data. The test module 32 includes at least two test components 33, and the test components 33 are electrically connected to the host module 31. The number of test components 33 is greater than or equal to the number of lithium batteries 60 to be tested loaded on the restraint tray 20. The test component 33 includes an interactive port 34 and a test probe 35. The interactive port 34 is adapted to the data port 25. The test probe 35 is used to dock with the electrode of the lithium battery 60 to be tested so that the capacity separation test device 30 can perform a capacity separation test on the lithium battery 60 to be tested. Wherein, while the test probe 35 docks with the electrode of the lithium battery 60 to be tested, the interactive port 34 docks with the data port 25. The host module 31 obtains the capacity separation data of the lithium battery 60 to be tested through the test probe 35, and transmits the capacity separation data to the processing module 24 through the interactive port 34.

[0178] During the process of performing capacity testing on the lithium battery 60 under test by the capacity testing device 30, the test probe 35 interfaces with the electrodes of the lithium battery 60 under test, thereby enabling the capacity testing device 30 to obtain data information about the lithium battery 60 under test and process the data information through the host module 31. While the test probe 35 interfaces with the electrodes of the lithium battery 60 under test, the interactive port 34 of the test module 32 interfaces with the data port 25, and the detected data information parameters are transmitted to the processing module 24, which stores and processes the data information of the lithium battery 60 under test.

[0179] During the testing process, the detected data is transmitted to the processing module 24, thereby overlapping the data transmission process with the testing process, improving the production efficiency of the capacity sorting device 10. The interactive port 34 is connected to the data port 25 to enable data transmission between the sorting system and the processing module 24, allowing the sorting device 40 to classify and sort the lithium batteries 60 according to the data information of the lithium batteries 60 under test. Transmitting data through the interactive port 34 and the data port 25 effectively ensures the reliability and effectiveness of data transmission.

[0180] In some embodiments of the present application, the capacity separation testing device 30 is provided with an inspection station and a sorting station, and the testing module 32 is provided at the inspection station. The capacity separation testing device 30 also includes a transfer device 36 for moving the restraint tray 20 between the inspection station and the sorting station.

[0181] During the capacity separation test of the lithium batteries 60 to be tested, the restraint tray 20 loaded with the lithium batteries 60 to be tested is placed in the testing station, and the capacity separation test device 30 performs the capacity separation test on the lithium batteries 60 to be tested. After all the lithium batteries 60 to be tested in the restraint tray 20 are 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 after the capacity separation test.

[0182] In some embodiments of the present application, the sorting device 40 includes a retrieving assembly 41, a data acquisition assembly 45, and a movable axis module 47. The retrieving assembly 41 is used to remove the lithium battery 60 under test from the restraint tray 20. The data acquisition assembly 45 is used to obtain data information from the lithium battery 60 under test. The movable axis module 47 is used to drive the retrieving assembly 41 and the data acquisition assembly 45 to move. The movable axis module 47 can drive the retrieving assembly 41 to move between the capacity separation test device 30 and the conveyor device 50.

[0183] During the process of sorting the lithium batteries 60 to be tested by the sorting device 40, a movable axis module 47 is provided to drive the material picking assembly 41 and the data acquisition assembly 45 to move within a spatial range. After the lithium battery 60 to be tested is tested, the movable axis module 47 drives the material picking assembly 41 and the data acquisition assembly 45 to move to the lithium battery 60 to be tested, connects with the data port 25 through the data acquisition assembly 45, and obtains the data information in the processing module 24. At the same time, the material picking assembly 41 clamps the accompanying assembly 221 loaded with the target lithium battery 60 to be tested. The control system of the movable axis module 47 drives the material picking assembly 41 clamping the lithium battery 60 to be tested to the target position based on the acquired data information, and then classifies and sorts the lithium battery 60 to be tested.

[0184] In some embodiments of the present application, the data acquisition assembly 45 includes a probe assembly 46, which is adapted to the data port 25. When the picking assembly 41 picks up the lithium battery 60 to be tested from the restraint tray 20, the probe assembly 46 interfaces with the data port 25, allowing the control system of the movable axis module 47 to obtain data information of the lithium battery 60 to be tested. The control system of the movable axis module 47 controls the movable axis module 47 based on the data information of the lithium battery 60 to be tested.

[0185] In the process of the data acquisition component 45 acquiring the data information in the processing module 24, the probe component 46 is connected to the data port 25 so that the control system of the movable axis module 47 acquires the data information of the lithium battery to be tested 60. The control system of the movable axis module 47 controls the movable axis module 47 according to the data information of the lithium battery to be tested 60, so that the sorting device 40 automatically classifies and sorts the lithium battery to be tested 60 according to the capacity separation test results, thereby improving the production efficiency of the capacity separation equipment 10.

[0186] On the other hand, in some embodiments of the present application, the present application also provides a capacity separation device 10, comprising: a capacity separation test device 30 and a sorting device 40. The capacity separation test device 30 can accommodate at least one restraint tray 20, and perform a capacity separation test on the lithium battery 60 to be tested in the restraint tray 20. The sorting device 40 is used to sort the lithium battery 60 to be tested that has completed the capacity separation test. Among them, the sorting device 40 includes: a material picking component 41 and a clamping component 42. The material picking component 41 is used to take out 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.

[0187] During the capacity separation test of the lithium battery 60 to be tested, the lithium battery 60 to be tested is loaded, secured, and positioned using the restraint tray 20. The restraint tray 20 loaded with the lithium battery 60 to be tested is then placed into the capacity separation test device 30, and the capacity separation test is performed on the lithium battery 60 to be tested in the restraint tray 20 using the capacity separation test device 30. The lithium battery 60 to be tested is then sorted by the sorting device 40 based on the test results, and different categories of lithium battery 60 to be tested are sorted. In this way, the sorted lithium battery 60 to be tested is automatically sorted, reducing the workload of the staff and improving the capacity separation efficiency of the capacity separation device 10.

[0188] While the sorting device 40 is sorting 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 loaded with the lithium batteries 60 to be tested. After the clamping device 23 is opened, the accompanying assembly 221 loaded with the lithium batteries 60 to be tested is removed from the restraint tray 20 by the material removal assembly 41. The lithium batteries 60 to be tested are then classified and sorted according to the capacity test results.

[0189] In some embodiments of the present 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 twisting assembly 43 and a twisting motor 44. The twisting assembly 43 is adapted to the abutment bolt 2313, and the twisting motor 44 drives the twisting assembly 43 to rotate, so that the twisting assembly 43 drives the abutment bolt 2313 to rotate.

[0190] The abutment plate 2311 is fixedly mounted on the bracket assembly 21 and abuts the outermost fixture 22 in the bracket assembly 21. The support plate 2312 is disposed opposite the abutment plate 2311, with all fixtures 22 located between the support plate 2312 and the abutment plate 2311. The support plate 2312 is provided with a threaded hole. The abutment bolt 2313 is adapted to fit within the threaded hole and abuts the outermost fixture 22 in the bracket assembly 21. Turning the abutment bolt 2313 adjusts the abutment force of the abutment bolt 2313 on the fixture 22. A preload spring 2314 is sleeved on the abutment bolt 2313. One end of the preload spring 2314 abuts the fixture 22, while the other end abuts the support plate 2312. The preload spring 2314 applies an elastic thrust to the fixture 22.

[0191] In the bracket assembly 21, the fixtures 22 are linearly arranged between the abutment plate 2311 and the support plate 2312, with the outermost fixtures 22 respectively abutting the abutment plate 2311 and the abutment bolts 2313. Tightening the abutment bolts 2313 provides thrust to maintain the fixtures 22 in close contact with each other. To remove the lithium battery 60 to be tested from the fixture 22, the abutment bolts 2313 are loosened, thereby releasing the tight push on the fixture 22, allowing the first and second fixture assemblies 222, 223 in the fixture 22 to release their tight grip on the accompanying assembly 221, allowing the accompanying assembly 221 loaded with the lithium battery 60 to be tested to be removed from between the first and second fixture assemblies 222, 223. Preload springs 2314 provide preload to the fixtures 22, ensuring that adjacent fixtures 22 are always in close contact with each other, thereby preventing the fixtures 22 from shaking in the bracket assembly 21 and ensuring the stability of the fixtures 22's position.

[0192] During the process of the opening and closing assembly 42 opening or closing the thrust assembly 231, the twisting assembly 43 is docked with the abutment bolt 2313, and the twisting motor 44 is used to drive the twisting 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 release of the fixing device 22 by the clamping device 23.
