[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] like Figures 1 to 8 As shown, an embodiment of the present application provides a baking tray, which includes a fixed heating plate 100 and a dynamic heating plate 200 .

[0045] The dynamic heating plate 200 and the fixed heating plate 100 are used to clamp the battery 1200 and heat the battery 1200. The heating surface of the dynamic heating plate 200 and the heating surface of the fixed heating plate 100 are opposite to each other, so that when the battery 1200 is clamped, the heating surfaces of the dynamic heating plate 200 and the fixed heating plate 100 can both contact the battery 1200, thereby heating the battery 1200 on both sides, shortening the heating time and improving the heating efficiency of the battery 1200.

[0046] The dynamic heating plate 200 can move relative to the fixed heating plate 100 to adjust the distance between the dynamic heating plate 200 and the fixed heating plate 100, so that the dynamic heating plate 200 and the fixed heating plate 100 can clamp batteries 1200 of different sizes, so as to heat batteries 1200 of different sizes and complete the baking of batteries 1200 of different sizes. Optionally, the battery 1200 can be an aluminum shell battery, of course, it can also be a battery of other structures, which is not limited herein.

[0047] In the embodiment of the present application, the movable heating plate 200 and the fixed heating plate 100 are used to clamp the battery 1200 and heat the battery 1200. The distance between the movable heating plate 200 and the fixed heating plate 100 is adjustable, so that the movable heating plate 200 and the fixed heating plate 100 can clamp batteries 1200 of different sizes, that is, the baking tray can be compatible with batteries 1200 of different sizes, so as to bake batteries 1200 of different sizes. It can be seen that the embodiment of the present application can solve the problem of poor size compatibility of the baking tray with the battery 1200 in the prior art.

[0048] When placing the battery 1200 in the baking tray, the thickness direction of the battery 1200 is consistent with the direction from the dynamic heating plate 200 to the fixed heating plate 100, and the distance between the dynamic heating plate 200 and the fixed heating plate 100 is adjusted so that the dynamic heating plate 200 and the fixed heating plate 100 can clamp batteries 1200 of different thicknesses.

[0049] The height direction of the battery 1200 is consistent with the height direction of the dynamic heating plate 200 and the fixed heating plate 100. The pole of the battery 1200 is placed with its back to the bottom heating plate 300 (see below). The pole does not contact the fixed heating plate 100, the dynamic heating plate 200 and the bottom heating plate 300. Batteries 1200 of different heights can be placed in the baking tray.

[0050] The width direction of the battery 1200 is consistent with the width direction of the dynamic heating plate 200 and the fixed heating plate 100. Optionally, the width of the baking tray can be 1150 mm. Taking the maximum width of the battery 1200 as 310 mm as an example, three rows of batteries 1200 can be placed between a group of fixed heating plates 100 and dynamic heating plates 200 with opposite heating surfaces. For batteries 1200 of different widths, different numbers of rows of batteries 1200 can be placed according to the width of the batteries 1200. The compatible size of the baking tray for the maximum width of the battery 1200 is the width of the baking tray.

[0051] The number of the fixed heating plate 100 and the number of the movable heating plate 200 may both be one, or may both be multiple, for example, 12. When the number of the fixed heating plate 100 and the number of the movable heating plate 200 are both multiple, the fixed heating plate 100 and the movable heating plate 200 are arranged alternately, the heating surfaces of all the fixed heating plates 100 face the same direction, the heating surfaces of all the movable heating plates 200 face the same direction, and the adjacent fixed heating plates 100 and the movable heating plates 200 with opposite heating surfaces form a group for clamping the battery 1200. In this case, the baking tray can bake multiple batteries 1200 at the same time, which can improve the baking efficiency.

[0052] In order to achieve adjustable distance between the fixed heating plate 100 and the dynamic heating plate 200, in an optional embodiment, an elastic member, such as a coil spring, can be connected between a group of fixed heating plates 100 and the dynamic heating plate 200 with opposite heating surfaces. When the elastic member is not subjected to external force, the elastic member can drive the fixed heating plate 100 and the dynamic heating plate 200 to fit each other. When the battery 1200 needs to be heated and baked, the dynamic heating plate 200 in each group of fixed heating plates 100 and dynamic heating plates 200 can be pushed by external force to move away from the fixed heating plate 100 to adjust the distance between a group of fixed heating plates 100 and the dynamic heating plate 200 with opposite heating surfaces.

[0053] In another preferred embodiment, all the movable heating plates 200 can be connected by a linkage 600 so that all the movable heating plates 200 can move synchronously. Under this structure, the movement of the linkage 600 or any one of the movable heating plates 200 can drive all the movable heating plates 200 to move, and the operation is simple and convenient. In addition, since all the fixed heating plates 100 are fixed in position and all the movable heating plates 200 are linked and connected, in the absence of external force, when the distance between the movable heating plates 200 and the fixed heating plates 100 relative to each group of heating surfaces is the same, even after the movable heating plates 200 are moved, it can be ensured that the distance between the fixed heating plates 100 and the movable heating plates 200 relative to each group of heating surfaces is always the same, which is convenient for baking multiple batteries 1200 of the same size in one baking operation.

[0054] Optionally, the linkage member 600 may be a linkage rod, and each dynamic heating plate 200 may be connected to the linkage member 600 by bonding, screw connection, clamping, etc., so that the linkage member 600 and all dynamic heating plates 200 can move synchronously.

[0055] The number of linkage parts 600 can be one or more. When the number of linkage parts 600 is multiple, at least two linkage parts 600 are respectively connected to the two opposite sides of the dynamic heating plate 200. For example, the number of linkage parts 600 can be four, and the two opposite sides of the dynamic heating plate 200 are respectively connected to two linkage parts 600. This structure can improve the connection stability between all the dynamic heating plates 200.

[0056] In the case where there are multiple fixed heating plates 100, all the fixed heating plates 100 can be connected to the same fixing member 500, and all the movable heating plates 200 can be slidably connected to the fixing member 500, so that the movable heating plates 200 can move relative to the corresponding fixed heating plates 100. This structure allows the movable heating plates 200 to be connected to the fixed heating plates 100, thereby improving the integration of the baking tray.

[0057] In order to further improve the integration of the baking tray and improve the safety during the baking process of the battery 1200, the baking tray may include a frame 400, and the frame 400 may have a receiving groove, and the fixed heating plate 100, the movable heating plate 200, and the linkage 600 may all be arranged in the receiving groove, and when the battery 1200 is placed in the baking tray, the pole of the battery 1200 faces the notch of the receiving groove. In this case, the fixed heating plate 100 and the movable heating plate 200 are both located in the frame 400, reducing the exposure of the fixed heating plate 100 and the movable heating plate 200, and can reduce the safety hazards caused by the heating of the fixed heating plate 100 and the movable heating plate 200.

[0058] When the dynamic heating plate 200 and the linkage member 600 are located in the receiving groove, the linkage member 600 may collide with the groove wall of the receiving groove during movement. For this reason, buffer pads 800 may be provided at both ends of the linkage member 600 along the moving direction of the linkage member 600. The buffer pads 800 may be rubber pads. In this case, during the movement of the linkage member 600, the buffer pads 800 located at both ends of the linkage member 600 contact the frame 400, thereby alleviating the problem of damage to the linkage member 600 caused by the collision between the linkage member 600 and the frame 400.

[0059] There are many types of fixing parts 500. In an optional embodiment, the fixing part 500 may also be a partial side wall of the frame 400. That is to say, all the fixed heating plates 100 may be directly connected to the frame 400 by means of screw connection, bonding, clamping, etc. The part of the frame 400 that forms the fixing part 500 may be provided with a slide rail, and the linkage part 600 or all the dynamic heating plates 200 may be provided with a slider, and the slider and the slide rail are slidably matched to make all the dynamic heating plates 200 slidably connected to the fixing part 500.

[0060] In another optional embodiment, the fixing member 500 can be a component independent of the frame 400 and dedicated to connecting each fixed heating plate 100, such as a fixing rod. Each fixed heating plate 100 can be fixedly connected to the fixing member 500 by bonding, screwing, clamping, etc., and the fixing member 500 can be connected to the inner wall of the frame 400 by bonding, screwing, clamping, etc.

[0061] In the case where the fixing member 500 is a component independent of the frame 400, the fixing member 500 and the linkage member 600 located on the same side of the fixed heating plate 100 and the dynamic heating plate 200 can be distributed along the height direction of the frame 400. It should be noted that the height direction mentioned herein is consistent with the direction from the notch to the bottom of the notch of the frame 400, and the width direction is perpendicular to the thickness direction and the height direction.

[0062] The number of the fixing members 500 may be one or more. When the number of the fixing members 500 is more than one, at least two fixing members 500 are respectively connected to two opposite sides of the fixed heating plate 100. This structure can improve the connection stability between all the fixed heating plates 100.

[0063] In order to achieve the sliding connection between all the dynamic heating plates 200 and the fixing member 500, in an optional embodiment, in the surfaces opposite to the fixing member 500 and the linkage member 600, and the surfaces opposite to the linkage member 600 and the fixing member 500, one may be provided with a guide groove 510, and the other may be rotatably provided with a rolling member 610, at least part of the rolling member 610 extends into the guide groove 510 and can roll in the guide groove 510, so that the linkage member 600 and the fixing member 500 are slidably matched, and then all the dynamic heating plates 200 and the fixing member 500 are slidably matched.

[0064] In another optional embodiment, the fixing member 500 may be provided with a guide groove 510, and all the dynamic heating plates 200 may be provided with a rolling member 610, and the rolling member 610 may be rotatably connected to the dynamic heating plate 200, and all the rolling members 610 may at least partially extend into the guide groove 510, and may roll in the guide groove 510, so that all the dynamic heating plates 200 are slidably connected to the fixing member 500. Under this structure, each dynamic heating plate 200 is slidably connected to the fixing member 500 through the rolling member 610, which can improve the connection stability of each dynamic heating plate 200 and the fixing member 500.

[0065] Optionally, the rolling element 610 may be a pulley, and may be a bearing.

[0066] In order to improve the connection stability of the dynamic heating plate 200 and the fixed heating plate 100, the two opposite surfaces of the fixing member 500 may be provided with guide grooves 510, and the same side of the dynamic heating plate 200 may be provided with at least two rolling members 610, wherein the two rolling members 610 are respectively matched with the two guide grooves 510 on the same fixing member 500. Of course, in a further technical solution, the other side of the dynamic heating plate 200 may also be provided with at least a rolling member 610, and the fixing member 500, the linkage member 600 and the rolling member 610 located on the two opposite sides of the dynamic heating plate 200 and the fixed heating plate 100 have the same structure and matching relationship.

[0067] When all the movable heating plates 200 are driven to move relative to all the fixed heating plates 100 , the linkage member 600 may be manually pushed so that the linkage member 600 drives all the movable heating plates 200 to move.

[0068] In a more preferred embodiment, the baking tray may further include a driving mechanism, which may be connected to the linkage member 600. Starting the driving mechanism can drive the linkage member 600 to drive all the dynamic heating plates 200 to move. In this case, the automation of the baking tray can be improved and the labor intensity of the staff can be reduced.

[0069] In an optional embodiment, the driving mechanism may include a telescopic cylinder such as a pneumatic cylinder, and the cylinder rod of the telescopic cylinder is connected to the linkage member 600 to drive the linkage member 600 and all the dynamic heating plates 200 to move.

[0070] In another optional embodiment, the driving mechanism may include a driving motor 710, a push rod 720 and an elastic member 730. The driving motor 710 may be a linear motor. The power output end of the driving motor 710 may be connected to the push rod 720 to drive the push rod 720 to move. The end of the push rod 720 may be opposite to the linkage member 600, and is used to push the linkage member 600 to drive each dynamic heating plate 200 to move in the first direction, so as to increase the distance between a group of dynamic heating plates 200 and a fixed heating plate 100 with opposite heating surfaces.

[0071] When there are multiple linkage members 600 and at least two linkage members 600 are respectively connected to two opposite sides of the dynamic heating plate 200 , there are at least two driving mechanisms, which are respectively used to drive the linkage members 600 located at two opposite sides of the dynamic heating plate 200 .

[0072] One end of the elastic member 730 can be connected to the linkage member 600 by means of screw connection, hook connection, etc., and the other end can be connected to the fixing member 500 or any fixed heating plate 100 by means of screw connection, hook connection, etc. The elastic member 730 is used to drive the linkage member 600 to drive each dynamic heating plate 200 to move in the second direction, so that the distance between a group of dynamic heating plates 200 and the fixed heating plate 100 with opposite heating surfaces is reduced, and the second direction is opposite to the first direction.

[0073] Optionally, the elastic member 730 may be a tension spring, or an elastic column or a coil spring, etc. Optionally, the elastic member 730 may always be in a compressed state, or the elastic member 730 may always be in an extended state, or the elastic member 730 may be in an original length state when not subjected to an external force, and after the push rod 720 pushes the linkage member 600 to drive the dynamic heating plate 200 to move, the elastic member 730 is deformed and accumulates elastic potential energy to restore the deformation. Optionally, the number of elastic members 730 may be multiple, and they may be distributed at equal distances.

[0074] In the specific process of baking the battery 1200, the drive motor 710 is turned on, and the drive motor 710 drives the push rod 720 to move. After the end of the push rod 720 contacts the linkage 600, the drive motor 710 drives the push rod 720, the linkage 600 and all the movable heating plates 200 to move together, so that the distance between a group of movable heating plates 200 and the fixed heating plate 100 with opposite heating surfaces is increased, and under the supporting force provided by the push rod 720, the movable heating plate 200 and the fixed heating plate 100 are stably maintained at a certain distance.

[0075] After the distance between the dynamic heating plate 200 and the fixed heating plate 100 is greater than the preset thickness value of the battery 1200, the driving motor 710 stops driving the push rod 720 to move, and a manipulator or other device is used to place the battery 1200 between the dynamic heating plate 200 and the fixed heating plate 100 with opposite heating surfaces, and place it close to the heating surface of the fixed heating plate 100. After the baking tray is filled with batteries 1200, the driving motor 710 drives the push rod 720 to move in a direction away from the linkage member 600, the supporting force of the push rod 720 on the linkage member 600 is reduced, the deformation of the elastic member 730 is reduced, and the linkage member 600 is driven to drive all the dynamic heating plates 200 to move in the second direction, so that a group of fixed heating plates 100 and dynamic heating plates 200 with opposite heating surfaces clamp the battery 1200, and the loading process is completed.

[0076] After the loading is completed, each heating plate (the fixed heating plate 100 , the movable heating plate 200 and the bottom heating plate 300 ) is powered on to heat the battery 1200 , so as to complete the baking of the battery 1200 .

[0077] After the battery 1200 is baked, the battery 1200 can be taken out of the baking tray using a robot or other device, and then the drive motor 710 drives the push rod 720 to move away from the linkage member 600. As the support force of the push rod 720 on the linkage member 600 decreases until it disappears, the deformation of the elastic member 730 continues to decrease, and drives the linkage member 600 to drive all the dynamic heating plates 200 to move in the second direction, so that the distance between a group of dynamic heating plates 200 and the fixed heating plate 100 with opposite heating surfaces returns to the initial minimum distance.

[0078] Optionally, when the linkage member 600 is not acted upon by the push rod 720, the elastic member 730 can drive a group of dynamic heating plates 200 and fixed heating plates 100 with heating surfaces facing each other to abut against each other. Of course, in other embodiments, when the linkage member 600 is not acted upon by the push rod 720, a group of dynamic heating plates 200 and fixed heating plates 100 with heating surfaces facing each other can also have a certain gap, and the gap sizes between the dynamic heating plates 200 and fixed heating plates 100 with heating surfaces facing each other in each group are equal.

[0079] In the above solution, the baking tray may include a frame 400, the frame 400 may have a receiving groove, the fixed heating plate 100 and the dynamic heating plate 200 are both arranged in the receiving groove, and in the embodiment of the present application, the bottom of the receiving groove may have a bottom heating plate 300, and the bottom heating plate 300 and a group of dynamic heating plates 200 and fixed heating plates 100 opposite to the heating surface enclose a heating space. In this case, the fixed heating plate 100, the dynamic heating plate 200 and the bottom heating plate 300 heat the battery 1200 on three sides, thereby improving the heating efficiency and shortening the baking time.

[0080] The structures of the dynamic heating plate 200, the fixed heating plate 100 and the bottom heating plate 300 can be the same, and can all include a support plate 910, a heat insulation plate 920, a heating plate 930 and a protective layer 940 that are stacked and connected in sequence. The support plate 910 can be an aluminum plate, which plays a role in supporting and fixing the heat insulation plate 920 and the heating plate 930. The heat insulation plate 920 can isolate the heating plate 930 from transferring heat to the support plate 910 to prevent heat loss. The heating plate 930 can be a heating sheet that can provide a heat source for heating the battery 1200. The material of the protective layer 940 can be Teflon. The protective layer 940 is arranged on the surface of the heating plate 930 that is away from the heat insulation plate 920. The surface where the protective layer 940 is located forms a heating surface. The protective layer 940 is used to protect the battery 1200 from friction with the heating plate 930 to prevent the surface of the battery 1200 from being scratched.

[0081] In an optional embodiment, the protective layer 940 can be an anti-scratch film, and the support plate 910, the heat insulation plate 920, the heating plate 930 and the protective layer 940 can be connected to each other by bonding. Of course, the support plate 910, the heat insulation plate 920, the heating plate 930 and the protective layer 940 can also be connected by other means, which is not limited in this article.

[0082] In another optional embodiment, the protective layer 940 may be a coating, and the support plate 910 , the heat insulation plate 920 , and the heating plate 930 may be connected to each other by bonding, and a protective material (such as Teflon) may be coated on the heating plate 930 to form the protective layer 940 .

[0083] In order to power on the heating plate 930, the frame 400 of the baking tray can be provided with at least one first probe group 1000, and the fixed heating plate 100, the dynamic heating plate 200 and the bottom heating plate 300 can all be electrically connected to the first probe group 1000, and the first probe group 1000 is used to electrically connect to the external second probe group.
