Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0060] like Figure 6 to Figure 7 As shown, the lithium battery clamp trolley 100 type vacuum baking equipment includes: a loading station 1000, an unloading station 2000, a clamp trolley 100, and a baking device 600.

[0061] A fixture trolley 100, a first opening 110 is formed on one side of the fixture trolley 100, a fixture 120 is disposed on the inner side of the fixture trolley 100, and the fixture 120 can enter and exit the fixture trolley 100 through the first opening 110;

[0062] like Figure 4 As shown, the fixture trolley 100 is a box structure with pulleys, and a first opening 110 is formed on the side of the fixture trolley 100. A sliding assembly 130 is provided on the inner side of the fixture trolley 100 so that the fixture 120 can be partially or completely withdrawn from the inner side of the fixture trolley 100, so as to facilitate the lithium battery to be placed in the fixture 120. In addition, it can be explained that the fixture 120 includes a plurality of fixtures 120, each of which is arranged in a horizontal direction and parallel to each other.

[0063] The baking device 600 is used to bake the lithium battery. Figure 6 As shown, a second opening is formed on one side of the baking device 600, and the second opening is used to allow the clamp vehicle 100 to enter and exit the baking device 600;

[0064] A loading station 1000 is used to place lithium batteries into a fixture 120;

[0065] It is understandable that a worker may be arranged at the loading station 1000 to perform manual loading, or an automatic loading device may be arranged at the loading station 1000 to perform automatic loading.

[0066] The unloading station 2000 is used to remove the lithium battery from the fixture 120 .

[0067] It is understandable that the material unloading can be performed manually by arranging staff at the unloading station 2000, or automatic unloading equipment can be arranged at the unloading station 2000 to perform automatic unloading.

[0068] When the lithium battery clamp trolley 100 type vacuum baking equipment is working, the wound lithium battery will be moved to the loading station 1000. At the same time, at least one clamp trolley 100 is located at the loading station 1000, and the clamp 120 is pulled out from the clamp trolley 100. The loading station 1000 loads the lithium battery to the clamp 120, and then the clamp 120 is pushed into the clamp trolley 100. Next, the clamp trolley 100 loaded with the lithium battery is moved into the baking device 600 through the second opening, and the lithium battery is baked by the baking device 600. After the baking is completed, the clamp trolley 100 is moved to the unloading station 2000, the clamp 120 is pulled out from the clamp trolley 100, the unloading station 2000 takes out the lithium battery, and then the clamp 120 is pushed into the clamp trolley 100.

[0069] It can be understood that the fixture cart 100 has a simple structure and is independently arranged from the baking device 600, so that the fixture cart 100 can load more lithium batteries. In addition, multiple fixture carts 100 can be provided, and different fixture carts 100 are installed with fixtures 120 that are compatible with lithium batteries of different sizes, thereby improving the adaptability of the lithium battery fixture cart 100-type vacuum baking equipment. When the baking device 600 is baking the lithium batteries in the fixture cart 100, another fixture cart 100 can be loaded at the loading station 1000 at the same time, thereby improving production efficiency.

[0070] like Figure 1 As shown, according to some embodiments of the present application, a sliding assembly 130 is provided in the fixture cart 100 , and the fixture 120 is slidably connected to the sliding assembly 130 , and the fixture 120 can move in and out of the fixture cart 100 along the sliding assembly 130 .

[0071] For example, the sliding assembly 130 includes a roller group, and the roller group is arranged corresponding to the clamp 120, a horizontally extending slideway is formed between the roller groups, the clamp 120 is arranged on the slideway, and the clamp 120 and the roller group are slidably matched. It can be understood that the clamp 120 can enter and exit the clamp vehicle 100 along the slideway.

[0072] For another example, the fixture 120 is provided with a roller group, the sliding assembly 130 includes a track, and the track is arranged in a horizontal direction. The fixture 120 slides along the track through the roller group, so that the fixture 120 can enter and exit the fixture vehicle 100.

[0073] According to some embodiments of the present application, the lithium battery clamp cart 100 type vacuum baking equipment also includes a push-pull device 200, which is used to pull the clamp 120 out or push it into the clamp cart 100, and the push-pull device 200 is arranged at the loading station 1000 and the unloading station 2000.

[0074] like Figures 6 to 7As shown, each of the loading station 1000 and the unloading station 2000 is provided with at least one push-pull device 200 for pulling out or pushing the fixture 120 into the fixture vehicle 100 .

[0075] like Figure 4 As shown, the push-pull device 200 includes: a third frame 210 , a fourth frame 240 , a third driving assembly 230 , a fixing assembly 270 , and a fourth driving assembly 260 .

[0076] The third frame 210 is provided with a third guide rail 220, and the third guide rail 220 is arranged along the height direction;

[0077] The fourth frame 240 is slidably connected to the third guide rail 220 , and a fourth guide rail 250 is disposed on the fourth frame 240 , and the fourth guide rail 250 is disposed in a horizontal direction.

[0078] The third driving assembly 230 is drivingly connected to the fourth frame 240;

[0079] It can be understood that the third driving assembly 230 can drive the fourth frame 240 to slide along the third guide rail 220, so that the fourth frame 240 drives the fixing assembly 270 to rise or fall.

[0080] The fixing assembly 270 is slidably connected to the fourth guide rail 250 , and the fixing assembly 270 is detachably connected to the clamp 120 ;

[0081] The fourth driving assembly 260 drives the connection and fixing assembly 270 .

[0082] It can be understood that the fourth driving assembly 260 can drive the fixing assembly 270 to slide along the fourth guide rail 250, so that the fixing assembly 270 moves in the horizontal direction.

[0083] It can be explained that when the push-pull device 200 is working, the position of the fixing assembly 270 can be adjusted through the third guide rail 220 and the fourth guide rail 250, so that the fixing assembly 270 is fixed to the clamp 120. In addition, after the fixing assembly 270 is fixed to the clamp 120, the fourth driving assembly 260 drives the fixing assembly 270 to move horizontally, so that the fixing assembly 270 can pull the clamp 120 out of the clamp trolley 100, or the fixing assembly 270 can push the clamp 120 into the clamp trolley 100.

[0084] According to some embodiments of the present application, the clamp 120 is provided with a first fixing portion 121 , the fixing assembly 270 includes a second fixing portion 271 , and the first fixing portion 121 and the second fixing portion 271 are detachably connected.

[0085] like Figure 4As shown, the fixing assembly 270 includes a frame, and the second fixing portion 271 is disposed on the frame. The second fixing portion 271 includes a telescopic component, and a fixing hole is formed on the first fixing portion 121, and the telescopic component can be inserted into or removed from the fixing hole. It can be understood that the first fixing portion 121 and the second fixing portion 271 are detachably connected through the telescopic function of the telescopic component.

[0086] It can be explained that when the clamp 120 needs to be pulled out of the clamp cart 100, the telescopic component will be partially inserted into the fixing hole, so that the fixing assembly 270 is fixed to the clamp 120, making it easier to pull out the clamp 120.

[0087] In addition, when the clamp trolley 100 has finished loading or unloading lithium batteries and the clamp 120 is pushed into the clamp trolley 100, the telescopic component will leave the fixing hole, thereby separating the fixing assembly 270 from the clamp 120, making it easier to transfer the clamp trolley 100.

[0088] According to some embodiments of the present application, the lithium battery clamp cart 100 type vacuum baking equipment further includes a robot 400 , and the robot 400 is used to place the lithium battery into the clamp 120 or remove the lithium battery from the clamp 120 .

[0089] like Figures 6 to 7 As shown, each of the loading station 1000 and the unloading station 2000 is provided with at least one robot 400 .

[0090] like Figure 5 As shown, the robot 400 includes: a first frame 410 , a second frame 440 , a first driving assembly 430 , a clamping assembly 470 , and a second driving assembly 460 .

[0091] The first frame 410 is provided with a first guide rail 420, and the first guide rail 420 is arranged along the height direction;

[0092] The second frame 440 is slidably connected to the first guide rail 420, and the second frame 440 is provided with a second guide rail 450, and the second guide rail 450 is arranged in a horizontal direction;

[0093] The first driving assembly 430 is drivingly connected to the second frame 440 .

[0094] It can be understood that the first driving assembly 430 can drive the second frame 440 to slide along the first guide rail 420, so that the second frame 440 drives the clamping assembly 470 to rise or fall.

[0095] The clamping assembly 470 is slidably connected to the second guide rail 450, and the clamping assembly 470 is used to clamp the lithium battery;

[0096] The second driving assembly 460 drives the connecting clamping assembly 470 .

[0097] It can be understood that the third driving assembly 230 can drive the clamping assembly 470 to slide along the second guide rail 450, so that the clamping assembly 470 moves in the horizontal direction.

[0098] It can be explained that when the manipulator 400 is working, the position of the clamping assembly 470 can be adjusted by the first guide rail 420 and the second guide rail 450, so that the clamping assembly 470 can clamp the lithium battery transferred from the front processing equipment to the loading station 1000 and put it into the fixture 120, or it can facilitate the clamping assembly 470 to unload the lithium battery on the fixture 120 to the processing equipment behind the unloading station 2000.

[0099] like Figures 2 to 3 As shown, according to some embodiments of the present application, the baking device 600 includes: a housing 610 , a vacuum assembly, a sleeve 630 , a movable part 660 , a driving component 670 , and a movable door 680 .

[0100] The housing 610 is provided with a receiving cavity 611, a through hole and a fixing member 612, wherein the fixing member 612 is provided in the receiving cavity 611; an electrical connection member 620 is provided on a side of the fixing member 612 facing the through hole and opposite to the through hole, and a through hole is formed on one side of the housing 610;

[0101] The vacuum component is used to evacuate the accommodating chamber 611;

[0102] The sleeve 630 is disposed at the through hole;

[0103] The movable member 660 is slidably disposed in the sleeve 630; the movable member 660 is hollow inside, and a partition plate 640 is disposed on the inner wall of the movable member 660, and the partition plate 640 is used to separate the inside of the movable member 660 into a first space 631 and a second space 632, wherein the first space 631 can be connected to the accommodating cavity 611, and the second space 632 is connected to the outside; a probe 650 is disposed on the partition plate 640, and two ends of the probe 650 are respectively located in the first space 631 and the second space 632;

[0104] The driving component 670 is used to drive the movable member 660 to abut against or separate from the fixed member 612. When the end of the movable member 660 abuts against the fixed member 612, the fixed member 612 closes the first space, and the probe 650 is connected to the electrical connector 620.

[0105] The movable door 680 is disposed corresponding to the second opening and can open and close the second opening.

[0106] It can be understood that the partition plate 640 on the inner wall of the movable member 660 separates the inside of the movable member 660 into a first space 631 and a second space 632, and the partition plate 640 can prevent gas exchange between the first space 631 and the second space 632, and the first space 631 can be connected to the accommodating chamber 611, while the second space 632 is connected to the outside; the sleeve 630 is arranged at the through hole, and the movable member 660 is slidably arranged in the sleeve 630, and the sleeve 630 is used to limit the moving direction of the movable member 660, and the through hole can be closed by the sleeve 630 and the movable member 660 to prevent the accommodating chamber 611 from being connected to the outside through the through hole; when there is still air in the accommodating chamber 611, the movable member 660 is located on the side away from the fixed member 612, the first space 631 is connected to the accommodating chamber 611, and the driving component 670 drives the movable member 66 0 is moved close to the fixing member 612 until the end of the movable member 660 is in contact with the fixing member 612, and the first space 631 is closed by the fixing member 612, so that air exists in the first space 631, and the electrical connector 620 is wrapped in the first space 631, so that the probe 650 is electrically connected to the electrical connector 620; and the accommodating chamber 611 is evacuated by the vacuum component, so that the battery in the accommodating chamber 611 is in a vacuum environment. Since the fixing member 612 separates the first space 631 from the accommodating chamber 611, gas exchange between the first space 631 and the accommodating chamber 611 is avoided. Since there is still air in the first space 631, the second space 632 is connected to the outside world, so that the probe 650 can work in a normal environment, and vacuum discharge phenomenon of the probe 650 during operation is avoided, so as to ensure that the baking device 600 can work normally.

[0107] In addition, it can be understood that the movable door 680 includes a door body and a sixth driving mechanism. Under normal conditions, the door body does not block the second opening, which facilitates the clamp vehicle 100 to enter the accommodating chamber 611. After the clamp vehicle 100 enters the accommodating chamber 611, the sixth driving mechanism causes the door body to close the second opening, so that the housing 610 forms a closed state, which facilitates the baking device 600 to perform vacuum baking.

[0108] like Figure 6 to Figure 7 As shown, according to some embodiments of the present application, the lithium battery clamp cart 100-type vacuum baking equipment also includes a moving device 500, the moving device 500 includes a slide rail 510 and a fifth drive assembly, the slide rail 510 connects the loading station 1000, the unloading station 2000, and the baking device 600, and the fifth drive assembly is used to drive the clamp cart 100 to slide along the slide rail 510.

[0109] It can be understood that when the lithium battery clamp cart 100 vacuum baking equipment is working, the fifth drive assembly can drive the clamp cart 100 to move along the slide rail 510 from the loading station 1000 to the baking device 600. After baking, the clamp cart 100 can move to the unloading station 2000 through the slide rail 510 to realize the automatic transfer of the clamp cart 100.

[0110] According to some embodiments of the present application, the slide rail 510 includes a main path 511 and an auxiliary path (the auxiliary path is not shown in the figure), the main path 511 extends from the loading station 1000 to the unloading station 2000, and the auxiliary path extends from the main path 511 to the baking device 600.

[0111] like Figure 6 As shown, the loading station 1000 and the unloading station 2000 are arranged opposite to each other, the main road 511 linearly connects the loading station 1000 and the unloading station 2000, the auxiliary road extends from the main road 511 into the baking device 600, and the auxiliary road is arranged perpendicular to the main road 511.

[0112] It can be understood that by providing the main road 511 and the auxiliary road, the regularity of the lithium battery clamp vehicle 100 type vacuum baking equipment can be improved and the mutual interference between various devices or components can be reduced.

[0113] According to some embodiments of the present application, the baking devices 600 include at least two, and the baking devices 600 are arrayed and distributed on one side or both sides of the main road 511 .

[0114] In order to increase the baking rate, the baking device 600 is provided with multiple Figure 6 As shown, the baking devices 600 are neatly arranged on one side or both sides of the main road 511 . In order to improve space utilization, the baking devices 600 are arranged on both sides of the main road 511 .

[0115] According to some embodiments of the present application, the lithium battery clamp cart 100 type vacuum baking equipment also includes a transport device, which is used to transport the clamp cart 100 to the slide rail 510 at the loading station 1000, or to transport the clamp cart 100 on the guide rail at the unloading station 2000 to the ground.

[0116] The lithium battery production line comprises: the above-mentioned lithium battery fixture trolley 100 type vacuum baking equipment, cooler 700, and liquid injection machine 300, wherein the lithium battery fixture trolley 100 type vacuum baking equipment, cooler 700, and liquid injection machine 300 are sequentially arranged along the processing direction of the lithium battery.

[0117] It can be understood that the robot 400 at the unloading station 2000 transfers the baked lithium batteries from the clamping vehicle 100 to the cooler 700. After cooling is completed, the cooled lithium batteries are transferred to the liquid injection machine 300 by the robot 400 or manual or other handling devices, and then liquid is injected.

[0118] Reference below Figures 1 to 7 The operation process of a lithium battery production line of the embodiment of the present application is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the present application.

[0119] The wound lithium batteries produced in front are transported to the loading station 1000.

[0120] The unloaded fixture trolley 100 is transported to the push-pull device 200 at the loading station 1000 by the transport device. Specifically, the fixture trolley 100 is transported to the third frame 210, and the third drive assembly 230 drives the fourth frame 240 to slide along the third guide rail 220. The fourth drive assembly 260 drives the fixing assembly 270 to slide along the fourth guide rail 250 to control the relative position of the fixing assembly 270 and the fixture 120, so that the first fixing part 121 and the second fixing part 271 are fixed, and then the fourth frame 240 is moved horizontally in the direction away from the fixture trolley 100, so as to pull out the fixture 120. It should be noted that part of the fixture 120 is still located in the fixture trolley 100, so as to facilitate the fixture 120 to be pushed back into the fixture trolley 100.

[0121] The manipulator 400 at the loading station 1000 is used to transfer the wound lithium battery to the fixture vehicle 100. Specifically, the first driving assembly 430 drives the second frame 440 to slide along the first guide rail 420, and the second driving assembly 460 drives the clamping assembly 470 to slide along the second guide rail 450 to control the position of the clamping assembly 470, so that the clamping assembly 470 transfers the wound lithium battery to the clamp 120 that has been pulled out of the fixture vehicle 100.

[0122] After the fixture 120 has been loaded, the fixture 120 is pushed back into the fixture vehicle 100 by the push-pull device 200, and the above operation is repeated to complete the loading of all or part of the fixtures 120 in the fixture vehicle 100.

[0123] It is understandable that at least one auxiliary road extends to the push-pull device 200, and after the clamp trolley 100 is loaded, it can move along the auxiliary road to the main road 511. It should be noted that the height of the third guide rail 220 is higher than the height of the clamp trolley 100, and the fourth rack 240 can be moved to the highest position of the third guide rail 220 to make the fourth rack 240 avoid the clamp trolley 100. When moving from another auxiliary road to the baking device 600, the lithium battery in the clamp trolley 100 is vacuum baked by the baking device 600. It can be explained that multiple clamp trolleys 100 can be included so that baking lithium batteries and loading lithium batteries can be carried out simultaneously.

[0124] After baking is completed, the clamp vehicle 100 re-enters the main road 511 through the auxiliary road, enters the unloading station 2000 through the main road 511, and enters the push-pull device 200 at the unloading station 2000 through the auxiliary road.

[0125] The push-pull device 200 pulls out the fixture 120, and the manipulator 400 at the unloading station 2000 transfers the baked lithium battery on the fixture 120 to the cooler 700. After cooling, the lithium battery is transferred to the liquid injection machine 300 for liquid injection. It can be explained that the manipulator 400 may include multiple manipulators 400 so that multiple transfer processes are performed simultaneously, or only one manipulator 400 may be included. When the lithium battery is cooled, the cooled lithium battery is transferred to the liquid injection machine 300, or when the lithium battery is injected, the lithium battery is transferred to the cooler 700.

[0126] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
