[0033] The present utility model provides a baking device.
[0034] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the baking device 100 includes a housing 110 and a baking mechanism 200. The housing 110 is provided with a baking chamber. The baking mechanism 200 includes a heating coil 300 disposed in the baking chamber. The heating coil 300 has a heating channel 310 extending in the up and down direction. The heating channel 310 is used for placing the shelled battery cell 900. The heating coil has a heating state for generating an alternating magnetic field in the heating channel 310. It can be understood that after the heating coil 300 is energized with alternating current, it will enter the heating state. In the heating state, for the shelled battery cell 900 placed in the heating channel 310, the alternating magnetic field will cause eddy currents to be generated in the shelled battery cell 900, so that the shelled battery cell 900 can be heated, and then the moisture in the shelled battery cell 900 can be evaporated. Since the alternating magnetic field directly acts on the shelled battery cell 900, it is beneficial to reduce the loss of heat during the transfer process, making the heating efficiency of the baking device 100 for the shelled battery cell 900 relatively high.
[0035] It is worth mentioning that the size of the heating coil 300 of the present application can be set according to actual needs and is not limited here.
[0036] Refer to together Figure 4, in some embodiments, the baking mechanism 200 further includes a lifting module 400 disposed in the baking chamber. The lifting module 400 is disposed below the heating channel 310. The lifting module 400 is used to partially lift the cased battery cell 900 out of the upper end of the heating channel 310. The baking device 100 further includes a transfer mechanism 500 disposed in the baking chamber. The transfer mechanism 500 includes a mechanical claw 550 for picking and placing the cased battery cell 900 in the heating channel 310. Thus, for the baked cased battery cell 900, after the lifting module 400 partially lifts the cased battery cell 900 out of the upper end of the heating channel 310 extending in the up and down direction, the mechanical claw 550 can conveniently grasp the cased battery cell 900 to take the cased battery cell 900 out of the heating channel 310. Of course, in some alternative embodiments, the baking mechanism 200 includes a lifting module disposed in the baking chamber. The lifting module is disposed below the heating channel 310. The lifting module is used to carry the cased battery cell 900. During the descending process, the lifting module can separate the cased battery cell 900 from the lower end of the heating channel 310 to facilitate the mechanical claw 550 to grasp it. During the ascending process, the cased battery cell 900 can be brought into the heating channel 310.
[0037] In some embodiments, the lifting module 400 includes a lifting member 420 and a lifting cylinder 410 drivingly connected to the lifting member 420. The lifting member 420 is provided with a first bearing position 421 for bearing the cased battery cell 900. The first bearing position 421 is oppositely arranged with the lower end of the heating channel 310 in the up and down direction. Thus, supported by the lifting member 420, the cased battery cell 900 can be stably placed in the heating channel 310. Of course, in some alternative embodiments, the baking mechanism 200 can additionally provide a bearing member, and the bearing member is used to replace the bearing function of the aforementioned lifting member 420. The bearing member is fixedly connected to the machine shell 110, that is, the lifting module 400 is specifically used to partially lift the cased battery cell 900 out of the upper end of the heating channel 310. In some other embodiments, the lifting cylinder 410 can be replaced by a motor and a ball screw cooperating with the motor to drive the lifting member 420, or can be replaced by a single-axis linear module to drive the lifting member 420.
[0038] In some embodiments, the lifting module 400 further includes a support seat 430 disposed on the machine shell 110 and a guide rod 440 connecting the support seat 430 and the lifting member 420. The guide rod 440 extends in the up and down direction. Thus, the lifting member 420 runs relatively smoothly, and the cased battery cell 900 can be relatively smoothly lifted out by the lifting member 420, avoiding structural interference between the cased battery cell and the heating coil.
[0039] In some embodiments, there are multiple heating coils 300, and there are multiple first bearing positions 421. One heating coil 300 is arranged corresponding to one first bearing position 421. In this way, one lifting member 420 can partially lift multiple cased battery cells 900 out of the upper end of the heating channel 310, which is beneficial to improving the efficiency of the lifting module 400 to lift the cased battery cells 900 out.
[0040] There are many distribution ways of the first bearing positions 421. In some embodiments, multiple first bearing positions 421 are arranged at intervals in the first direction. It should be understood that the first direction is different from the up-down direction. However, the present design is not limited thereto. In other embodiments, multiple first bearing positions 421 are arranged in a circular array, and the axis around which multiple first bearing positions 421 are surrounded extends in the up-down direction.
[0041] Referring together to Figure 5 and Figure 6 , in some embodiments, there are a loading position and an unloading position in the baking cavity. The baking device 100 further includes a loading mechanism 600 for conveying the cased battery cells 900 to the loading position, and an unloading mechanism 700 for unloading the cased battery cells 900 located at the unloading position. The mechanical claw 550 is used to convey the cased battery cells 900 located at the loading position to the heating channel 310, and to convey the cased battery cells 900 located in the heating channel 310 to the unloading position. In this way, the loading mechanism 600, the unloading mechanism 700, and the transfer mechanism 500 replace manual loading and unloading, which is beneficial to improving the automation level of the baking device 100.
[0042] There are many structural forms of the transfer mechanism 500. In some embodiments, the transfer mechanism 500 further includes a first driving module 510 for driving the mechanical claw 550 to move in the second direction, and a second driving module 520 for driving the mechanical claw 550 to move in the up-down direction. The loading position, the heating coil 300, and the unloading position are arranged in sequence in the second direction. In this way, driven by the first driving module 510, the mechanical claw 550 can pass through the loading position, the heating coil 300, and the unloading position. Driven by the second driving module 520, the mechanical claw 550 can realize the picking and placing of the cased battery cells 900 at the loading position, the heating channel 310, and the unloading position. However, the present design is not limited thereto. In some alternative embodiments, the transfer mechanism 500 includes a multi-axis manipulator cooperating with the mechanical claw 550.
[0043] In some embodiments, there are two first driving modules 510 arranged in parallel, and the second driving module 520 is connected to the two first driving modules 510 through a first adapter frame 530. In this way, it is beneficial to the stable operation of the mechanical claw 550 in the second direction.
[0044] There are many structural forms of the loading mechanism 600. In some embodiments, the loading mechanism 600 includes a loading member 620 for carrying the cased battery cells 900, and a loading driving module 610 for driving the loading member 620 to move in the second direction. Driven by the loading driving module 610, the loading member 620 conveys the cased battery cells 900 to the loading position. Of course, in some alternative embodiments, the structural form of the loading mechanism 600 can also be other, as long as it can load the cased battery cells 900 to be baked.
[0045] There are many structural forms of the unloading mechanism 700. In some embodiments, the unloading mechanism 700 includes an unloading member 720 for carrying the cased battery cells 900, and an unloading driving module 710 for driving the unloading member 720 to move in the second direction. Driven by the unloading driving module 710, the unloading member 720 unloads the cased battery cells 900 located at the unloading position. Of course, in some alternative embodiments, the structural form of the loading mechanism 600 can also be other, as long as it can unload the cased battery cells 900 after baking.
[0046] In some embodiments, there are multiple mechanical claws 550. In this way, the transfer mechanism 500 can sequentially pick and place multiple cased battery cells 900. In some embodiments, the multiple mechanical claws 550 are connected to the second driving module 520 through a second adapter bracket 540. The second adapter bracket 540 provides multiple mounting positions for the multiple mechanical claws 550.
[0047] In some embodiments, there are multiple baking mechanisms 200, and the multiple baking mechanisms 200 are arranged in parallel in the second direction. In this way, it is beneficial to improve the baking efficiency of the baking device 100 for the cased battery cells 900.
[0048] In some embodiments, the lifting member 420 is provided with multiple first bearing positions 421, the multiple first bearing positions 421 are spaced apart in the first direction, the multiple mechanical claws 550 are spaced apart in the first direction, the loading member 620 is provided with multiple second bearing positions 621 spaced apart in the first direction, the second bearing positions 621 are used to carry the cased battery cells 900, and the unloading member 720 is provided with multiple third bearing positions 721 spaced apart in the first direction, the third bearing positions 721 are used to carry the cased battery cells 900. A mechanical claw 550 is arranged corresponding to a first bearing position 421, a second bearing position 621, and a third bearing position 721. In this way, the multiple mechanical claws 550 of the transfer mechanism 500 can grab multiple cased battery cells 900 located on the loading member 620 at one time, pick and place multiple cased battery cells 900 into multiple heating channels 310 at one time, and place multiple cased battery cells 900 after baking on the unloading member 720 at one time. It is beneficial to improve the working efficiency of the baking device 100.
[0049] In some embodiments, the baking device 100 further includes an air extraction device 800 disposed on the casing 110, and the air extraction device 800 is used to extract the gas in the baking cavity. Thus, the moisture evaporated from the in-casing battery cell 900 will be extracted by the air extraction device 800, which is beneficial to improving the baking efficiency of the baking device 100 for the in-casing battery cell 900.
