[0034] Reference Figure 1 、 Figure 2 as well as Figure 4 As shown, the battery cell baking device involved in the embodiment of the present application includes: a plurality of infrared baking components 100 and a supporting component 200.

[0035] Specifically, multiple infrared baking components 100 are arranged at intervals along the first direction x, and the infrared baking components 100 include infrared baking lamps 110; the supporting component 200 includes a conveying member 210, which is transmitted along the first direction x and is used to carry the battery cells, and the infrared baking lamps 110 are arranged toward the conveying member 210.

[0036] It should be noted that the first direction x is Figure 1 The direction pointed by x.

[0037] In the battery cell baking device of the present application, since the conveying member 210 is transmitted along the first direction x, the battery cell can be transported along the first direction x on the conveying member 210, and since the infrared baking lamp 110 is arranged toward the conveying member 210, the battery cell can be baked by the infrared baking lamp 110 during the process of being transported. The infrared baking lamp 110 uses infrared radiation to bake the battery cell, which has the characteristics of fast temperature rise, strong penetration and good uniformity. In this way, the battery cell can be heated quickly, thereby improving the baking efficiency of the battery cell. At the same time, due to Multiple infrared baking components 100 are arranged at intervals along the first direction x. Therefore, multiple infrared baking components 100 can further increase the speed at which the battery cells are heated and improve the baking efficiency of the battery cells. Furthermore, the conveying of the battery cells by the conveying member 210 can also improve the baking efficiency of the battery cells. When one of the battery cells is baked, it can be sent out of the baking position by the conveying member 210. At the same time, the next battery cell can also be transported to the baking position by the conveying member 210, thereby improving the baking efficiency of the battery cells. Therefore, the battery cell baking device of the present application can improve the baking efficiency of the battery cells.

[0038] Specifically, refer to Figure 1 as well as Figure 2As shown, in this embodiment, the conveying member 210 is a conveyor belt, which is driven along the first direction x so that the battery cells can be conveyed along the first direction x on the conveyor belt. In addition, the conveying member 210 can also be a conveying member 210 such as a conveyor chain that can convey the battery cells along the first direction x.

[0039] Reference Figure 2 as well as Figure 4 As shown, the carrier assembly 200 further includes a carrier 220 , which is connected to the conveyor 210 and is transmitted along the first direction x with the conveyor 210 . The infrared baking lamp 110 is arranged toward the carrier 220 , and the carrier 220 is used to fix the battery cell.

[0040] In this embodiment, the battery cell can be fixed on the carrier 220. When the carrier 220 is transmitted along the first direction x with the conveying member 210, the carrier 220 can drive the battery cell to be transmitted along the first direction x. At the same time, the carrier 220 can prevent the battery cell from moving relative to the conveying member 210 during the transmission along the first direction x, thereby reducing the friction between the battery cell and the conveying member 210 and reducing damage to the battery cell. Furthermore, since the infrared baking lamp 110 is arranged toward the carrier 220, when the battery cell is fixed on the carrier 220, the infrared baking lamp 110 can be irradiated onto the battery cell, thereby achieving baking of the battery cell through the infrared baking lamp 110.

[0041] Reference Figure 2 As shown, there are multiple carriers 220 , which are arranged on the conveying member 210 along the first direction x, and the carriers 220 move along the first direction x and pass through each infrared baking lamp 110 in sequence.

[0042] In this embodiment, since the supporting assembly 200 has multiple supporting members 220, multiple battery cells can be fixed by the multiple supporting members 220, so that the multiple battery cells can be transmitted along the first direction x on the conveying member 210, and since the supporting member 220 moves along the first direction x and passes through each infrared baking lamp 110 in turn, each battery cell fixed on the supporting member 220 can move along the first direction x and pass through each infrared baking lamp 110 in turn, so that each battery cell can be baked by multiple infrared baking lamps 110. In this way, the purpose of multiple battery cells being baked by multiple infrared baking lamps 110 in turn can be achieved, thereby further improving the baking efficiency of the battery cells.

[0043] Reference Figure 2 As shown, a carrying groove 221 is provided on the carrying member 220, and the carrying groove 221 is used for placing the power core.

[0044] In this embodiment, the battery cell can be placed in the supporting groove 221 of the supporting member 220, so as to achieve the fixation of the battery cell by the supporting member 220, so that the battery cell can be transmitted along the first direction x on the conveying member 210, and the battery cell will not move relative to the conveying member 210 during the transmission along the first direction x.

[0045] Continue to refer to Figure 2 As shown, a plurality of bearing grooves 221 are provided on the bearing member 220, and the plurality of bearing grooves 221 are arranged at intervals along the second direction y, the second direction y intersects with the first direction x, the infrared baking lamp 110 extends along the second direction y, and each bearing groove 221 is located within the length range of the infrared baking lamp 110 along the second direction y.

[0046] It should be noted that the second direction y is Figure 1 The direction indicated by y.

[0047] In this embodiment, since a plurality of carrying slots 221 are provided on the carrier 220, a plurality of battery cells can be fixed on the carrier 220 through the plurality of carrying slots 221. Moreover, since the plurality of carrying slots 221 are arranged at intervals along the second direction y, and each of the carrying slots 221 is located within the length range of the infrared baking lamp 110 along the second direction y, when the carrier 220 moves along the first direction x and passes through the infrared baking lamp 110, the plurality of battery cells fixed on the carrier 220 can be irradiated by the infrared baking lamp 110, so as to realize simultaneous baking of the plurality of battery cells on the carrier 220. In this way, the baking efficiency of the battery cells can be further improved.

[0048] Specifically, refer to Figure 3As shown, the carrier 220 includes a carrier portion 222, two first limiting portion groups 223 and a plurality of second limiting portion groups 224, the carrier portion 222 is connected to the conveying member 210, each first limiting portion group 223 and each second limiting portion group 224 are connected to the side of the carrier portion 222 facing the infrared baking lamp 110, wherein the two first limiting portion groups 223 are respectively connected to the two ends of the carrier portion 222 along the second direction y, and the plurality of second limiting portion groups 224 are arranged between the two first limiting portion groups 223 and are spaced apart along the second direction y, and each first limiting portion group 223 is spaced apart along the second direction with the second limiting portion group 224 adjacent thereto to define a plurality of bearing slots 221 between the two first limiting portion groups 223 and the plurality of second limiting portion groups 224; wherein each first limiting portion group 223 includes two first limiting portion groups 223. The limiting portion 2231, the two first limiting portions 2231 are symmetrically arranged at the two ends of the bearing portion 222 along the first direction x, each first limiting portion 2231 has an L-shaped limiting wall 225, each second limiting portion group 224 includes two second limiting portions 2241, the two second limiting portions 2241 are symmetrically arranged at the two ends of the bearing portion 222 along the first direction x, each second limiting portion 2241 has two L-shaped limiting walls 225 spaced apart along the second direction y, any four L-shaped limiting walls 225 are arranged around a battery cell to define a bearing slot 221 between the four L-shaped limiting walls 225, each L-shaped limiting wall 225 is in contact with a corner of the battery cell, and the bearing portion 222 has anti-slip grooves on the side facing the infrared baking lamp 110 and on each L-shaped limiting wall 225 to prevent the battery cell from moving in the bearing slot 221.

[0049] Reference Figure 4 As shown, the infrared baking assembly 100 further includes a lampshade 120 , which is disposed outside the infrared baking lamp 110 . The width of the lampshade 120 along the first direction x gradually increases from a direction away from the conveying member 210 to a direction close to the conveying member 210 .

[0050] In this embodiment, since the lampshade 120 is arranged outside the infrared baking lamp 110, the lampshade 120 can protect the infrared baking lamp 110 and prevent the infrared baking lamp 110 from being damaged by external factors. At the same time, the lampshade 120 can also gather the infrared light emitted by the infrared baking lamp 110 so that most of the infrared light can be irradiated onto the conveying member 210. Since the width of the lampshade 120 along the first direction x gradually increases from the direction away from the conveying member 210 to the direction close to the conveying member 210, when the lampshade 120 gathers the infrared light, it can also have a certain divergent effect on the infrared light, so that the infrared light can be irradiated onto a larger area of the conveying member 210, thereby ensuring that the infrared light can cover more battery cells, so that the infrared baking lamp 110 can bake more battery cells at the same time, further improving the baking efficiency of the battery cells.

[0051] Specifically, refer to Figure 4 As shown, in this embodiment, the lampshade 120 has a top plate 121 and two side plates 122, the two side plates 122 are respectively connected to the two ends of the top plate 121 along the first direction x, the infrared baking lamp 110 is connected to the side of the top plate 121 close to the conveying member 210, and is located between the two side plates 122, the ends of the two side plates 122 away from the conveying member 210 are respectively connected to the two ends of the top plate 121, and each infrared baking lamp 110 is located between the two side plates 122; wherein, the distance between the two side plates 122 gradually increases toward the direction close to the conveying member 210.

[0052] Continue to refer to Figure 4 As shown, there are multiple infrared baking lamps 110 , all of which are housed in a lampshade 120 , and the multiple infrared baking lamps 110 are arranged along a first direction x.

[0053] Specifically, in this embodiment, the number of infrared baking lamps 110 is two. In addition, in other embodiments, the number of infrared baking lamps 110 can also be three, four, five, etc. The specific number is determined according to the width of the carrier 220 along the first direction x and the width of the battery cell along the first direction x.

[0054] In this embodiment, since the plurality of infrared baking lamps 110 are arranged along the first direction x, the heat coverage of the battery cells can be increased by the plurality of infrared baking lamps 110, and the heating speed of the battery cells can be increased to further improve the baking efficiency of the battery cells. Since the plurality of infrared baking lamps 110 are all covered in the lampshade 120, each infrared baking lamp 110 can be protected by the lampshade 120, and the infrared light emitted by each infrared baking lamp 110 can be irradiated onto the conveyor 210.

[0055] Reference Figure 5 As shown, the battery cell baking device also includes a shell 300, the infrared baking component 100 and the supporting component 200 are both located in the shell 300, and the shell 300 is provided with a loading port 310 and a loading port 320, the loading port 310 is arranged at one end of the shell 300 along the first direction x, the loading port 320 is arranged at the other end of the shell 300 along the first direction x, and the conveying member 210 is located between the loading port 310 and the loading port 320.

[0056] In this embodiment, since the infrared baking component 100 and the supporting component 200 are both located in the outer shell 300, the infrared light of the infrared baking lamp 110 can be further concentrated through the outer shell 300, and the heat dissipation rate of the baking heat can be reduced to ensure the baking effect of the battery cells. Furthermore, since the loading port 310 is arranged at one end of the outer shell 300 along the first direction x, the unloading port 320 is arranged at the other end of the outer shell 300 along the first direction x, and the conveying member 210 is located between the loading port 310 and the unloading port 320, the battery cells to be baked can be placed on the supporting member 220 through the loading port 310, and the baked battery cells on the supporting member 220 can be taken out through the unloading port 320. In this way, the baked battery cells on the supporting member 220 can be replaced with the battery cells to be baked while the conveying member 210 continues to move along the first direction x, and there is no need for the conveying member 210 to stop moving. Therefore, the baking efficiency of the battery cells can be further improved.

[0057] Specifically, in this embodiment, the infrared baking component 100 also includes a fixing part 130, both ends of the lampshade 120 are connected to a fixing part 130, and the fixing part 130 is connected to the inner wall of the outer shell 300, so that the infrared baking component 100 is connected to the outer shell 300 through the fixing part 130, thereby achieving the fixation of the infrared baking component 100.

[0058] Reference Figure 1 As shown, the carrying assembly 200 includes multiple conveying members 210, which are arranged in the housing 300 at intervals along the third direction z, which is perpendicular to the first direction x. Each conveying member 210 is provided with multiple infrared baking lamps 110 on one side along the third direction z.

[0059] In this embodiment, since the carrying assembly 200 includes multiple conveying members 210, a carrying member 220 can be set on each conveying member 210, that is, a battery cell can be carried on each conveying member 210. Since each conveying member 210 is provided with multiple infrared baking lamps 110 on one side along the third direction z, the battery cells on each conveying member 210 can be baked by the infrared baking lamp 110. In this way, the baking positions of the battery cells can be further increased, so that more battery cells can be baked in the battery cell baking device of the present application, thereby further improving the baking efficiency of the battery cells.

[0060] Reference Figure 4 As shown, the battery cell baking device also includes a heat dissipation component 400, which includes a temperature detection component, a heat dissipation component and a controller. The temperature detection component is arranged close to the infrared baking lamp 110 and is used to detect the temperature of the infrared baking lamp 110. When the temperature signal value of the infrared baking lamp 110 received by the controller exceeds the preset temperature, the controller is used to send an opening instruction to the heat dissipation component according to the temperature signal.

[0061] Specifically, in this embodiment, the temperature detection component is a thermocouple temperature sensor, and the heat dissipation component is a heat dissipation fan. When the thermocouple temperature sensor is used to detect the temperature of the infrared baking lamp 110 and to transmit the temperature signal to the controller, when the temperature signal value of the infrared baking lamp 110 received by the controller exceeds the preset temperature, the controller is used to send an open instruction to the heat dissipation fan according to the temperature signal, so that the motor of the heat dissipation fan drives the fan to rotate, thereby generating a heat dissipation airflow to achieve a heat dissipation effect.

[0062] In this embodiment, the temperature of the infrared baking lamp 110 can be detected in real time through the temperature detection component. When the temperature of the infrared baking lamp 110 exceeds the preset temperature value, the battery cell is at risk of being damaged by high temperature. At this time, the controller can send an open instruction to the heat sink according to the received temperature signal of the infrared baking lamp 110, so that the heat sink can dissipate heat to the internal environment of the shell 300 to prevent the battery cell from being damaged by high temperature.
