Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery baking, in particular to a battery tray and a battery oven. BACKGROUND

[0002] When producing lithium ion batteries, a small amount of moisture is beneficial to the formation of positive and negative electrodes (solid electrolyte film, referred to as SEI film), but when the moisture exceeds the standard, the electrolyte lithium salt in the lithium ion battery will decompose, and the formation and stability of the positive and negative electrodes will be adversely affected, resulting in rapid deterioration of the electrochemical performance of the lithium ion battery. Therefore, it is necessary to strictly control the moisture during the production process of lithium ion batteries. However, in each process of production, the pole piece, the diaphragm and other parts inevitably absorb water, causing the moisture in the lithium ion battery to increase. In order to avoid the moisture in the lithium ion battery exceeding the standard, the lithium ion battery will be baked to remove water before being injected.

DETAILED DESCRIPTION

[0045] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0046] As Figure 1 shown, the application embodiment discloses a battery oven 1, comprising a shell 10, a plurality of support frames 11 and a plurality of battery magazines 12, the plurality of support frames 11 are installed inside the shell 10, the plurality of battery magazines 12 are respectively placed in the plurality of support frames 11, and the battery 9 is placed in the battery magazine 12. When the battery 9 is baked, the battery magazine 12 radiates and heats the battery 9, and the shell 10 is vacuumized.

[0047] As Figures 2-5 With Figures 6-10 As shown in the drawings, the battery magazine 12 of the embodiment of the present application comprises:

[0048] The frame 2 comprises a first fixed plate 21, a second fixed plate 22 and two L-shaped heating plates 23, the two L-shaped heating plates 23 are oppositely arranged, the two ends of the first fixed plate 21 are respectively fixedly connected with one end of the two L-shaped heating plates 23, the two ends of the second fixed plate 22 are respectively fixedly connected with the other end of the two L-shaped heating plates 23, the L-shaped heating plate 23 comprises a first lateral heating part 231 and a first bottom heating part 232, the first lateral heating part 231 and the first bottom heating part 232 are connected to form an L-shaped structure, and the first lateral heating part 231 and the first bottom heating part 232 are provided with a plurality of heat radiation elements;

[0049] A plurality of T-shaped heating plates 3 are arranged and installed on the frame 2 along the length direction of the L-shaped heating plate 23, the T-shaped heating plate 3 comprises a second lateral heating part 31, a second bottom heating part 32 and a plurality of spacing elements 33, the second lateral heating part 31 and the second bottom heating part 32 are connected to form a T-shaped structure, the second lateral heating part 31 and the second bottom heating part 32 are respectively provided with a plurality of first through holes 311 and a plurality of second through holes 321, the spacing elements 33 are arranged in the first through holes 311 and the second through holes 321, the second lateral heating part 31 and the second bottom heating part 32 are provided with a plurality of heat radiation elements, the two ends of the second lateral heating part 31 are respectively fixedly connected with the first lateral heating part 231 located at the two ends, the bottom surfaces of the two ends of the second bottom heating part 32 are respectively abutted with the top surfaces of the first bottom heating part 232 located at the two ends, and the battery 9 is placed between adjacent T-shaped heating plates 3, and the spacing elements 33 are used to form a spacing between the battery 9 and the lateral heating part and the bottom heating part.

[0050] The L-shaped heating plate 23 includes a first lateral heating part 231 and a first bottom heating part 232, which are connected to form an L-shaped structure. The T-shaped heating plate 3 includes a second lateral heating part 31, a second bottom heating part 32, and multiple spacer elements 33, which are connected to form a T-shaped structure. The multiple T-shaped heating plates 3 are arranged along the length of the L-shaped heating plate 23. The two ends of the second lateral heating part 31 are fixedly connected to the first lateral heating parts 231 located at both ends. The bottom surfaces of the two ends of the second bottom heating part 32 abut against the top surfaces of the first bottom heating parts 232 located at both ends, so that multiple mounting cavities for placing the battery 9 are formed between the L-shaped heating plates 23 on the left and right sides and the multiple T-shaped heating plates 3 arranged in sequence. Before baking, the battery 9 is placed in the mounting cavity between adjacent T-shaped heating plates 3. Since the first lateral heating part 231 and the first bottom heating part 232 are provided with multiple heat radiation elements, during the baking process of the battery 9, the first lateral heating part 231 and the first bottom heating part 232 of the two L-shaped heating plates 23 can radiate heat to the battery 9 from the left and right sides of the battery 9 respectively. The second lateral heating part 31 and the second bottom heating part 32 are provided with multiple heat radiation elements, so the second lateral heating part 31 of the adjacent T-shaped heating plates 3 can radiate heat to the battery 9 from the front and rear sides respectively, while the second bottom heating part 32 of the adjacent T-shaped heating plates 3 can radiate heat to the bottom of the battery 9 together, thereby increasing the heating area, improving the heating efficiency, reducing the baking time, and achieving high water removal efficiency. Since the battery 9 is placed between adjacent T-shaped heating plates 3, the T-shaped heating plates 3 will support the battery 9. In order to avoid the battery 9 from contacting the T-shaped heating plates 3, multiple first through holes 311 and multiple second through holes 321 are respectively provided in the second lateral heating part 31 and the second bottom heating part 32. The spacer element 33 is provided in the first through holes 311 and the second through holes 321. The spacer element 33 can make the battery 9 placed between adjacent T-shaped heating plates 3 separate from the lateral heating part and the bottom heating part, so that the T-shaped heating plate 3 can perform non-contact radiant heating on the battery 9.

[0051] It should be noted that the first lateral heating part 231 of the L-shaped heating plate 23 on both sides of the T-shaped heating plate 3 is fixedly connected to the second lateral heating part 31 of the T-shaped heating plate 3 by angle steel, and the first bottom heating part 232 of the L-shaped heating plate 23 at the bottom of the T-shaped heating plate 3 is fixedly connected to the second bottom heating part 32 of the T-shaped heating plate 3 by bolts.

[0052] like Figures 4-6 As shown, in some embodiments, the battery cassette 12 further includes:

[0053] A plurality of first limiting blocks 41 are arranged on the top of the second lateral heating part 31 and are arranged at intervals along the length direction of the second lateral heating part 31, and are used to separate adjacent batteries 9.

[0054] Since a plurality of batteries 9 can be placed between adjacent T-shaped heating plates 3, in order to avoid the mutual contact between the batteries 9 affecting the heating of the batteries 9, the first limiting blocks 41 are used to separate adjacent batteries 9, so that the batteries 9 can be better heated, and the water vapor evaporated by the batteries 9 can be better pumped.

[0055] It should be noted that the number of first limiting blocks 41 can be 1, 2, 3, 4, 5 or more, and the user can select according to the size and number of the batteries 9 to be baked and dried. In the embodiment, the number of first limiting blocks 41 is 6.

[0056] As shown in FIG. 1, Figures 2-5 In some embodiments, the battery magazine 12 further comprises:

[0057] A plurality of limiting rods 42 extend along the length direction perpendicular to the second lateral heating part 31, and any one of the limiting rods 42 is fixedly connected with a plurality of first limiting blocks 41 arranged on the top of the second lateral heating plate.

[0058] In order to ensure that each first limiting block 41 at the same position of the T-shaped heating plate 3 can ensure the same position, the battery magazine 12 is further provided with a plurality of limiting rods 42, the limiting rods 42 extend along the length direction perpendicular to the second lateral heating part 31, and the limiting rods 42 are fixedly connected with the first limiting blocks 41 fixedly connected with different second lateral heating parts 31 and arranged on the same straight line, so that the positional relationship of each first limiting block 41 is further strengthened.

[0059] Further, the limiting rod 42 is provided with a second limiting block 43 between adjacent first limiting blocks 41.

[0060] As the limiting rod 42 is arranged on the top of the T-shaped heating plate 3, in order to enable the battery 9 to be better placed between adjacent T-shaped heating plates 3 and to strengthen the limiting of the battery 9 in the length direction of the second lateral heating part 31, the limiting rod 42 is provided with a second limiting block 43 between adjacent first limiting blocks 41. When the battery 9 is placed between adjacent T-shaped heating plates 3, the left and right sides of the battery 9 are in contact with the left and right second limiting blocks 43, respectively, thereby limiting the position of the battery 9 in the length direction of the second lateral heating part 31. Then, the side of the battery 9 is in contact with the first limiting block 41, and the position of the battery 9 in the length direction of the second lateral heating part 31 and the thickness direction of the second lateral heating part 31 is limited by the first limiting block 41, so that the battery 9 is smoothly placed between adjacent T-shaped heating plates 3, and the transverse position of the battery 9 in the battery magazine 12 is fixed by the first limiting block 41 and the second limiting block 43.

[0061] It should be noted that the second limiting block 43 is a circular ring arranged on the limiting rod 42. Arranging the second limiting block 43 as a circular ring can reduce the collision and friction when the battery 9 is in contact with the second limiting block 43.

[0062] As shown in FIG. 1, Figures 6-7 in some embodiments, the first limiting block 41 includes:

[0063] a limiting part 411 including a first limiting part 4111 extending in the length direction of the second lateral heating part 31 and a second limiting part 4112 extending in the thickness direction of the second lateral heating part 31, the first limiting part 4111 and the second limiting part 4112 being connected to form a cross-shaped structure,

[0064] a connecting part 412 including a first connecting part 4121 connected to one end of the second limiting part 4112 and a second connecting part 4122 connected to the other end of the second limiting part 4112, the first connecting part 4121 being arranged on one side of the second lateral heating part 31, and the second connecting part 4122 being arranged on the other side of the second lateral heating part 31, the first connecting part 4121 being provided with a first screw hole, and the second connecting part 4122 being provided with a second screw hole;

[0065] the second lateral connecting part 412 is provided with a third screw hole, and a connecting element passes through the first screw hole, the third screw hole and the second screw hole to realize the fixed connection of the first limiting block 41 and the second lateral heating part 31;

[0066] the top of the second limiting part 4112 is provided with a plurality of fourth screw holes, the limiting rod 42 is provided with a plurality of fifth screw holes, and a connecting element passes through the fourth screw holes and the fifth screw holes to realize the fixed connection of the first limiting block 41 and the limiting rod 42.

[0067] Since the battery 9 is placed along the length direction of the second lateral heating part 31, the first limiting part 4111 extending along the length direction of the second lateral heating part 31 is arranged between the adjacent batteries 9 placed along the length direction of the second lateral heating part 31, so as to form a gap between the adjacent batteries 9. The second limiting part 4112 extending along the thickness direction of the second lateral heating part 31 can support the battery 9, so as to form a gap between the battery 9 and the second lateral heating part 31.

[0068] It should be noted that the limiting rod 42 in the embodiment can be a hollow hexagonal round bar. On one hand, the hollow hexagonal round bar can reduce the weight of the battery magazine 12. On the other hand, compared with a hollow round bar, the hollow hexagonal round bar will not roll when the connecting element passes through the fourth screw hole and the fifth screw hole to realize the fixed connection between the first limiting block 41 and the limiting rod 42, thereby facilitating the connection.

[0069] In some embodiments, the top of the first limiting part 4111 and the second limiting part 4112 is provided with a chamfer structure for guiding the battery 9 to be placed between the adjacent battery heating plates.

[0070] Since the battery 9 is placed from the top of the two T-shaped heating plates 3 into the two T-shaped heating plates 3 when placed into the battery magazine 12, in order to avoid the battery 9 from being scratched by the T-shaped heating plate 3 and to better place the battery 9 between the two T-shaped heating plates 3, the top of the first limiting part 4111 and the second limiting part 4112 is provided with a chamfer structure, thereby guiding the battery 9 to be placed between the two T-shaped heating plates 3.

[0071] As shown in FIG. 1, Figure 9 In some embodiments, the first lateral heating part 231 is provided with a plurality of first heating channels 2311 and a plurality of first hollow channels 2312, the plurality of first heating channels 2311 and the plurality of first hollow channels 2312 are arranged alternately, and the heat radiation element is arranged in the first heating channel 2311.

[0072] The first bottom heating part 232 is provided with a plurality of second heating channels 2321 and a plurality of second hollow channels 2322, the plurality of second heating channels 2321 and the plurality of second hollow channels 2322 are arranged alternately, and the heat radiation element is arranged in the second heating channel 2321.

[0073] The first lateral heating part 231 and the first bottom heating part 232 are respectively provided with a plurality of first heating channels 2311 and a plurality of second heating channels 2321, and the heat radiation element is arranged in the first heating channel 2311 and the second heating channel 2321, so as to radiate and heat the front and back sides and the bottom surface of the battery 9, increase the heating area, reduce the heating time, and improve the baking efficiency.

[0074] The arrangement of the plurality of first hollow passages 2312 and the plurality of second hollow passages 2322 in the first lateral heating part 231 and the first bottom heating part 232 respectively can reduce the overall weight of the T-shaped heating plate 3, thereby reducing the weight of the battery magazine 12 and the load of the support frame 11 in the battery oven 1. Meanwhile, the plurality of first heating passages 2311 and the plurality of first hollow passages 2312 are arranged alternately, and the plurality of second heating passages 2321 and the plurality of second hollow passages 2322 are arranged alternately, so that the first hollow passages 2312 and the second hollow passages 2322 can store the heat radiation of the heat radiation elements in the first heating passages 2311 and the second heating passages 2321 respectively, thereby avoiding the drastic change of heat and keeping the heating temperature stable, and ensuring the uniformity of the heating of the T-shaped heating plate 3 on the battery 9.

[0075] As shown in Figure 7 some embodiments, the second lateral heating part 31 is provided with a plurality of third heating passages 312 and a plurality of third hollow passages 313, and the plurality of third heating passages 312 and the plurality of third hollow passages 313 are arranged alternately, and the heat radiation elements are arranged in the third heating passages 312.

[0076] The second bottom heating part 32 is provided with a plurality of fourth heating passages 322 and a plurality of fourth hollow passages 323, and the plurality of fourth heating passages 322 and the plurality of fourth hollow passages 323 are arranged alternately, and the heat radiation elements are arranged in the fourth heating passages 322.

[0077] The arrangement of the plurality of third heating passages 312 and the plurality of fourth heating passages 322 in the second lateral heating part 31 and the second bottom heating part 32 respectively, and the arrangement of the heat radiation elements in the third heating passages 312 and the fourth heating passages 322 can radiate and heat the left and right sides of the battery 9, further increase the heating area, further reduce the heating time, and improve the baking efficiency.

[0078] The arrangement of the plurality of third hollow passages 313 and the plurality of fourth hollow passages 323 in the second lateral heating part 31 and the second bottom heating part 32 respectively can reduce the overall weight of the L-shaped heating plate 23, thereby reducing the weight of the battery magazine 12 and the load of the support frame 11 in the battery oven 1. Meanwhile, the plurality of third heating passages 312 and the plurality of third hollow passages 313 are arranged alternately, and the plurality of fourth heating passages 322 and the plurality of fourth hollow passages 323 are arranged alternately, so that the third hollow passages 313 and the fourth hollow passages 323 can store the heat radiation of the heat radiation elements in the third heating passages 312 and the fourth heating passages 322 respectively, thereby avoiding the drastic change of heat and keeping the heating temperature stable, and ensuring the uniformity of the heating of the T-shaped heating plate 3 on the battery 9.

[0079] It can be understood that the heat radiation element can be selected as an electric heating wire. When an electric current passes through the electric heating wire, an electromagnetic heating effect is generated. The electric heating wire is heated and emits heat radiation.

[0080] As shown in Figure 7 With Figure 9 In some embodiments, the first lateral heating part 231 and the first bottom heating part 232 are integrally formed in an L-shaped structure of aluminum material, and the second lateral heating part 31 and the second bottom heating part 32 are integrally formed in a T-shaped structure of aluminum material.

[0081] The L-shaped heating plate 23 and the T-shaped heating plate made of aluminum material have good mechanical strength, strong pressure bearing capacity, long service life, and uniform heat dissipation. The first lateral heating part 231 can fix the positions of the two ends of the T-shaped heating plate 3, and the first bottom heating part 232 can provide support to the bottom of the T-shaped heating plate 3 at the two ends of the T-shaped heating plate 3. The second lateral heating part 31 can provide lateral support to the battery 9 through the spacing element 33, and the second bottom heating part 32 can provide bottom support to the battery 9 through the spacing element 33, so that the battery 9 can be fixed in the battery magazine 12.

[0082] As shown in Figure 6 In some embodiments, the second bottom heating part 32 is further provided with a plurality of third through holes 324.

[0083] The battery magazine 12 further comprises a plurality of temperature measuring devices 5 fixedly connected with the second bottom heating part 32, and part of the temperature measuring devices 5 contact the bottom of the battery 9 through the third through holes 324 and measure the temperature of the battery 9.

[0084] Compared with the existing temperature measurement of the heating plate and the battery oven 1, part of the temperature measuring devices 5 contact the bottom of the battery 9 through the third through holes 324, so that the temperature of the battery 9 can be directly measured, the actual temperature of each battery 9 in the battery magazine 12 can be better measured, and the heating temperature can be better controlled.

[0085] As shown in Figures 2-5 In some embodiments, the battery magazine 12 further comprises:

[0086] A plurality of guide bearings 6 are installed on the L-shaped heating plate 23.

[0088] In the embodiment, the L-shaped heating plate 23 is provided with a plurality of guide bearings 6, and the support frame 11 is provided with guide rails. During the process of placing the battery magazine 12 into the battery oven 1, the guide bearings 6 on both sides of the battery magazine 12 can roll along the guide rails on both sides, so that the process of placing the battery magazine 12 into the support frame 11 becomes easy. It should be noted that in other embodiments, the L-shaped heating plate 23 is provided with 1, 2, 3, 4, or 5 guide bearings 6, and the specific number of guide bearings 6 can be adjusted according to actual needs.

[0089] Since the battery magazine 12 needs to supply power to the heating element for heating the battery 9, the battery magazine 12 is provided with a plurality of magazine power supply plugs 713, and the magazine power supply plugs 713 are installed on the second fixed plate 22. After the battery magazine 12 enters the battery oven 1 along the guide rails, the magazine power supply plugs 713 installed on the second fixed plate 22 are connected with the power supply plugs 13 installed on the shell 10, so that the battery oven 1 supplies power to the battery magazine 12, and the T-shaped heating plate 3 and the L-shaped heating plate 23 of the battery magazine 12 heat the battery 9 during the baking process. It can be understood that one of the magazine power supply plugs 713 and the power supply plugs 13 of the shell 10 is a male plug, and the other is a female plug.

[0090] In some embodiments, the circuit structure of the battery magazine 12 is arranged on the second fixed plate 22. In order to avoid the temperature of the circuit structure being too high and affecting the normal work of the circuit structure, the second fixed plate 22 is provided with a heat dissipation aluminum plate 8, which can accelerate the heat dissipation capacity of the circuit structure.

[0091] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application are still within the scope of the technical solution of the present application.
