[0039] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be a middle element at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time.

[0041] In addition, the descriptions involving "first", "second", etc. in the present invention are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] Terms such as the tray, capacitor, and material here are only for the need of description and should not be regarded as a limitation to this application.

[0043] As Figure 1 and Figure 2 As shown, an embodiment of the present application provides a baking device 100. The baking device 100 includes an oven 1, a moving component 2, and a supporting component 4. The baking device is used to accommodate a plurality of trays 500 stacked vertically and bake materials 600 such as capacitors and battery cells (hereinafter collectively referred to as materials 600) carried on the trays 500. The baked materials 600 can be supplied for use in the next process. The baking device 100 can be installed separately from the relevant devices in the subsequent process (such as an impregnating machine), or can be installed together to form a complete set of impregnating equipment, which is not limited here.

[0044] Inside the oven 1, there are a first baking area 11 and a second baking area 12 adjacent in the first direction ( Figure 1 the X direction in Figure 1 ). Both the first baking area 11 and the second baking area 12 can accommodate at most N layers of the trays 500, where N is greater than or equal to 2. The N trays are stacked vertically in the first baking area 11 and / or the second baking area 12, and at least part of the upper trays 500 can abut against the lower trays 500. In this embodiment, with the bottom layer of the first baking area 11 and the second baking area 12 as the first layer and the top layer as the Nth layer as a reference for description, it can be understood that the first baking area 11 and the second baking area 12 can be provided with three or more layers and can respectively accommodate 3 or more trays 500. At the bottom of one side of the oven 1, there is a gate 18 that can be opened or closed, and there is a loading position 400 outside the gate 18 of the oven 1. At least part of the moving component 2 is arranged inside the oven 1 and is used to drive the tray 500 to move along a set path. For example, it can drive the tray 500 to move along the set path in the first direction ( Figure 1In the Z direction, i.e., the height direction) for movement. Wherein the first direction is the length direction of the oven 1 (the direction between the first baking area 11 and the second baking area 12), and the second direction is the height direction of the oven 1. Understandably, if the first baking area 11 is close to the gate 18, then the second baking area 12 is far from the gate 18; alternatively, if the second baking area 12 is close to the gate 18, then the first baking area 11 is far from the gate 18. The first baking area 11 and the second baking area 12 of the oven 1 can accommodate at most N layers of the trays 500, that is, the baking oven 1 has 2N baking positions, which can be adjusted during actual use, that is, the number of the trays 500 can be increased or decreased according to actual needs, and no limitation is made here. The maximum number of trays 500 that the first baking area 11 and the second baking area 12 can accommodate can be equal or unequal. The loading position 400 can also be used to place the trays 500 for loading and unloading. For the convenience of description, the following are specific embodiments: (1) In both cases, the first baking area 11 is close to the gate 18 and the second baking area 12 is far from the gate 18; (2) The first baking area 11 and the second baking area 12 are described as accommodating the trays 500 from the first layer to the N - 1 layer; these two descriptions should not be regarded as a limitation to this application.

[0045] In some embodiments, a pair of opening / closing doors 19 are provided on the side of the oven 1 adjacent to the gate 18. Opening the pair of opening / closing doors 19 can be used to place the trays 500 on each layer of the first baking area 11 and the second baking area 12 of the oven 1 at the very beginning, or to open the pair of opening / closing doors 19 when performing maintenance on the baking device 100, etc. Generally, the pair of opening / closing doors 19 are closed.

[0046] Specifically, the oven 1 is a box-frame closed structure, internally divided into adjacent first baking area 11 and second baking area 12, and the gate 18 is provided at the bottom of one side of the first baking area 11 of the oven 1. The size of the tray 500 can match the size of the gate 18. Each layer of the first baking area 11 can accommodate one tray 500, and at most N layers of trays 500 can be accommodated in total. Similarly, the second baking area 12 can also accommodate at most N layers of trays 500.

[0047] The support assembly 4 is at least partially disposed inside the oven 1, used to at least support the trays 500 on the second layer of the first baking area 11 and / or the second baking area 12, and to allow the moving assembly 2 to pass through when moving the tray 500 back and forth between the first layer and the second layer of the second baking area 12.

[0048] Understandably, the tray 500 is used to carry the material 600. Therefore, the moving assembly 2 completes the entry and exit of the material 600 by moving the tray 500. When the tray 500 is input into the oven 1 from the loading position 400 or output from the oven 1 to the loading position 400, the gate 18 is always open. When the baking device 100 is baking, the gate 18 is always closed. There is a gap between the upper part of the tray 500 on the first layer and the bottom of the corresponding tray 500 on the second layer. The bottom of the tray 500 on the Nth layer can also abut against the tray 500 on the (N - 1)th layer. When the moving assembly 2 moves the tray 500 between the Nth layers in the first baking area 11 and the second baking area 12, there is also a gap between the bottom of the tray 500 on the Nth layer and the upper part of the corresponding tray 500 on the (N - 1)th layer. Hereinafter, taking all the trays 500 in the first baking area 11 and the second baking area 12 being unloaded (i.e., not carrying the material 600) as an example to illustrate the feeding working process of the baking device 100.

[0049] First step, the moving assembly 2 moves the tray 500 on the first layer in the first baking area 11 to the loading position 400. At the same time, the tray 500 on the first layer in the second baking area 12 is moved to the first layer in the first baking area 11. The first layer in the second baking area 12 is an empty position (i.e., not accommodating the tray 500). The material 600 to be baked is transferred to the tray 500 located at the loading position 400.

[0050] Second step, the moving assembly 2 moves the tray 500 on the first layer in the first baking area 11 and the tray 500 at the loading position 400 back to their original positions, that is, the tray 500 on the first layer in the first baking area 11 is moved to the first layer in the second baking area 12, and the tray 500 at the loading position 400 is moved to the first layer in the first baking area 11.

[0051] Third step, the moving assembly 2 moves the tray 500 (loaded with the material 600 to be baked) on the first layer in the first baking area 11 to the second layer. When the upper part of the tray 500 on the first layer abuts against the bottom of the tray 500 on the second layer, the moving assembly 2 then moves the tray 500 on the first layer to push all the trays 500 on it upward. When the tray 500 on the first layer is moved to the second layer, the support assembly 4 allows it to pass through and supports it on the second layer. After completing this step, the second layer to the Nth layer in the first baking area 11 all accommodate the tray 500.

[0052] In the fourth step, the moving component 2 lifts the tray 500 on the Nth layer of the first baking area 11 and moves it to the Nth layer of the second baking area 12. Then, the moving component 2 no longer lifts the tray 500 to let it abut against the tray 500 on the (N - 1)th layer of the second baking area 12. The moving component 2 moves the tray 500 on the first layer of the second baking area 12 to the first layer of the first baking area 11.

[0053] In the fifth step, the moving component 2 supports the tray 500 on the second layer of the second baking area 12 (as can be known from the above description, actually it will support the trays 500 from the second layer to the Nth layer). Then, the supporting component 4 no longer supports the tray 500 on the second layer to let it move downward. The moving component 2 moves the tray 500 on the second layer of the second baking area 12 to the first layer, and each of the other layers will move down one layer, that is, the tray 500 on the third layer will move to the second layer and be supported by the supporting component 4. At this time, the trays 500 are accommodated in the first layer to the (N - 1)th layer of the first baking area 11 and the second baking area 12. However, at this time, the tray 500 on the second layer of the first baking area 11 carries the material 600 to be baked.

[0054] In the sixth step, repeat the first step to the fifth step until the trays 500 on each layer all carry the material 600 to be baked. At this time, the material 600 on the tray 500 on the first layer of the second baking area 12 is the first to be loaded, and so on. The material 600 on the tray 500 on the first layer of the first baking area 11 is the last to be loaded. Then, the baking device 100 can be started to bake for the first predetermined time.

[0055] The following continues to describe the feeding and discharging during the baking process of the baking device 100.

[0056] In the seventh step, the moving component 2 moves the tray 500 on the first layer of the first baking area 11 to the second layer. There are trays 500 from the second layer to the Nth layer in the first baking area 11. The moving component 2 moves the tray 500 on the first layer of the second baking area 12 to the first layer of the first baking area 11.

[0057] In the eighth step, the moving component 2 lifts the tray 500 on the Nth layer of the first baking area 11 and moves it to the Nth layer of the second baking area 12. The moving component 2 supports the tray 500 on the second layer of the second baking area 12 and moves it to the first layer. Similarly, it can be known that each of the other layers will move down one layer. The first layer to the (N - 1)th layer of the first baking area 11 and the second baking area 12 are all accommodating the trays 500, and the trays 500 are all carrying the materials 600. The Nth layer of the first baking area 11 and the second baking area 12 is in a vacant state. At this time, the material 600 on the tray 500 on the first layer of the first baking area 11 is the first to enter the oven 1, and the material 600 on the tray 500 on the first layer of the second baking area 12 is the second to enter the oven 1.

[0058] In the ninth step, open the gate 18. The moving component 2 moves the tray 500 on the first layer of the first baking area 11 to the loading position 400. At the same time, the tray 500 on the first layer of the second baking area 12 will move to the first layer of the first baking area 11, and then the gate 18 can be closed to continue baking. Unload the material 600 (the baked material 600) on the tray 500 at the loading position 400, and then load the tray 500 full of the material 600 to be baked, that is, loading and unloading, which takes a second predetermined time in total. The gate 18 can be opened after the loading and unloading is completed, or it can be opened after baking for a period of time. There is no limitation here. For the convenience of description, the gate 18 is opened after the loading and unloading is completed. The moving component 2 drives the tray 500 on the first layer of the first baking area 11 to reset to the first layer of the second baking area 12, and the tray 500 at the loading position 400 will also reset to the first layer of the first baking area 11. At this time, the material 600 on the tray 500 on the first layer of the second baking area 12 is the first to enter the oven 1, and the material 600 on the tray 500 on the first layer of the first baking area 11 is called the last to enter.

[0059] In the tenth step, close the gate 18, continue baking for the second predetermined time, and then return to the seventh step to realize cyclic loading and unloading.

[0060] By arranging the first baking area 11 and the second baking area 12 adjacent to each other along the length direction of the oven 1 in the oven 1, and each baking area can accommodate at most N layers of the trays 500 along the height direction of the oven 1, the number of layers of the trays 500 accommodated in each baking area can be adjusted according to needs, reducing the occupied area of the plane site. In addition, by cyclic loading and unloading, the production efficiency is improved.

[0061] For further reference Figure 2, in some embodiments, the moving component 2 includes a first lifting member 21 and a second lifting member 22. The first lifting member 21 is disposed in the oven 1, for example, below the first layer of the first baking area 11. The first lifting member 21 is configured to move the tray 500 in the first baking area 11 from the bottom layer to the top layer. The moving manner can be stepwise, that is, it moves upward by the distance of one layer each time. The second lifting member 22 is disposed in the oven 1. The second lifting member 22 is at least configured to move the tray 500 in the second baking area 12 from the top layer to the bottom layer. The moving manner can be stepwise, that is, it moves downward by the distance of one layer each time.

[0062] As Figure 4 shown, further, the first lifting member 21 includes a first supporting plate 210 and a first lifting driving portion 211. The first supporting plate 210 is disposed below the first baking area 11 and is configured to support the tray 500 at the bottommost layer of the first baking area 11. The first lifting driving portion 211 is connected to the first supporting plate 210. The first lifting driving portion 211 is configured to drive the first supporting plate 210 to lift the tray 500 at the first layer in the first baking area 11 to the second layer. During this process, the tray 500 at the first layer pushes up the original tray 500 at the second layer, thereby driving the trays 500 above it to move upward by one layer in sequence. The second lifting member 22 includes a second supporting plate 220 and a second lifting driving portion 221. The second supporting plate 220 is disposed below the second baking area 12 and is configured to support the tray 500 at the bottommost layer of the second baking area 12. The second lifting driving portion 221 is connected to the second supporting plate 220. The second lifting driving portion 221 is configured to drive the second supporting plate 220 to move back and forth at least between the first layer and the second layer in the second baking area 12.

[0063] Specifically, the first lifting drive unit 211 is disposed at the bottom of the oven 1 and is connected to the first tray 210. The first lifting drive unit 211 can drive the first tray 210 to move back and forth between the first layer and the second layer of the first baking area 11. When the first tray 210 carries the tray 500, the first lifting drive unit 211 can drive the first tray 210 to drive the tray 500 to move and pass through (go through) the support assembly 4 until the second layer, and the support assembly 4 supports the tray 500 on the second layer. Even if the first tray 210 descends to the first layer, the support assembly 4 can support the tray 500 on the second layer. As described above, when the first lifting drive unit 211 drives the first tray 210 to drive the tray 500 to lift from the first layer to the second layer, the original second layer to the (N - 1)th layer of the first baking area 11 all move up one layer accordingly (the Nth layer of the first baking area 11, that is, the top layer is in an idle state in advance). Similarly, when the second tray 220 carries the tray 500, the second lifting drive unit 221 can drive the second tray 220 to move the tray 500 through the support assembly 4 until the second layer, and the support assembly 4 supports the tray 500 on the second layer. The second lifting drive unit 221 can drive the second tray 220 to reset to the first layer. In addition, when the second tray 220 is at the position of the first layer of the second baking area 12 and the first layer of the second baking area 12 is in an idle state (not occupied by the tray 500), the second lifting drive unit 221 can drive the second tray 220 to rise to the second layer and support the trays 500 on the second layer and above. The support assembly 4 can control its action and no longer support the tray 500 on the second layer. The second lifting drive unit 221 can drive the second tray 220 to descend, so that the tray 500 on the second layer moves to the first layer. As described above, the original third layer to the (N - 1)th layer all move down one layer (if the Nth layer also accommodates the tray 500, it will drop to the (N - 1)th layer).

[0064] The first lifting drive unit 211 can be a combination of a motor and a lead screw pair. That is, the lead screw of the lead screw pair is threadedly connected to the first tray 210. The motor drives the lead screw pair to work, and the lead screw of the lead screw pair drives the first tray 210 to rise or fall, and thus can drive the tray 500 to move back and forth (lift) between the first layer and the second layer of the first baking area 11. The first lifting drive unit 211 can also be a cylinder. The piston of the cylinder is connected to the first tray 210. The extension or retraction of the piston can drive the tray 500 to move back and forth between the first layer and the second layer. It can also be other power mechanisms that can realize the lifting of the first tray 210, which are not limited here. Similarly, the second lifting drive unit 221 can also adopt any of the above power mechanisms, which are not limited here.

[0065] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, a loading position 400 is provided at the gate 18. The moving assembly 2 further includes a first translation member 31 and a second translation member 32. The first translation member 31 passes through the gate 18 and extends to the first layer of the oven 1 and the loading position 400. The first translation member 31 is configured to move the tray 500 at the loading position 400 to the first layer of the first baking area 11, and to move the tray 500 on the first layer of the second baking area 12 to the loading position 400. The second translation member 32 is disposed at the top sidewall of the oven 1. Before the first lifting member 21 moves all the trays 500 from the first layer to the (N - 1)th layer up by one layer, the second translation member 32 is configured to drive the tray 500 on the Nth layer of the first baking area 11 to the Nth layer of the second baking area 12.

[0066] The first translation member 31 includes the first translation driving portion 311 and two first moving portions 310 arranged in parallel at intervals. The first translation driving portion 311 is configured to drive the two first moving portions 310. The first translation driving portion 311 and the two first moving portions 310 extend through the gate 18 along the first layer of the oven 1 to the loading position 400. The first translation driving portion 311 is connected to both of the two first moving portions 310 and is configured to drive them to move synchronously. The second translation member 32 includes a second translation driving portion 321 and two second moving portions 320 arranged in parallel at intervals. The second translation driving portion 321 is configured to drive the two second moving portions 320. The two second moving portions 320 extend along the sidewall of the Nth layer of the oven 1. The second translation driving portion 321 is connected to both of the two second moving portions 320 and is configured to drive them to move synchronously.

[0067] Specifically, the first translation driving part 311 is located at one end of the two first moving parts 310 at the loading position 400 and is located between the two first moving parts 310. The first pallet 210 is located between the parts of the two first moving parts 310 in the first baking area 11, and the position of the first pallet 210 is slightly lower than that of the two first moving parts 310. The second pallet 220 is located between the parts of the two first moving parts 310 in the second baking area 12, and the position of the second pallet 220 is also slightly lower than that of the two first moving parts 310. When the first lifting driving part 211 does not drive the first pallet 210 to rise to a position higher than that of the two first moving parts 310, and the second lifting driving part 221 does not drive the second pallet 220 to rise to a position higher than that of the second moving part 320, the first layer of both the first baking area 11 and the second baking area 12 accommodates the tray 500, that is, the two first moving parts 310 at the positions in the first baking area 11 and the second baking area 12 carry the tray 500. The first translation driving part 311 can drive the first moving part 310 to drive the two trays 500 to move in the direction of the loading position 400, that is, the tray 500 on the first layer of the first baking area 11 moves to the loading position 400, and the tray 500 on the first layer of the second baking area 12 moves to the first layer of the first baking area 11. Some other situations can be easily inferred according to the above description and will not be elaborated here.

[0068] In some embodiments, both of the second moving parts 320 include a second guide rail 325 and a second sliding plate 326 slidably disposed on the second guide rail 325. The two second guide rails 325 respectively extend along the inner sides of the Nth layer side walls of the first baking area 11 and the second baking area 12. Both ends of the two second sliding plates 326 are provided with translation guide wheels 328. The space between the two second guide rails 325 allows the material tray 500 to pass through, and the two second sliding plates 326 can carry the material tray 500. The second translation driving part 321 is connected to the two second sliding plates 326 and is used to drive the two second sliding plates 326 to slide on the corresponding second guide rails 325 respectively. The second translation driving part 321 includes a second translation motor 323 and two second translation transmission parts 324. The two second translation transmission parts 324 respectively extend along the inner sides of the Nth layer side walls of the first baking area 11 and the second baking area 12 and are arranged side by side and spaced apart from the corresponding second guide rails 325 respectively. The two second translation transmission parts 324 are respectively connected to the second sliding plates 326 on the corresponding sides. The second translation motor 323 is connected to both of the second translation transmission parts 324. When the second translation motor 323 operates, it drives the two second translation transmission parts 324 to drive the corresponding second sliding plates 326 to slide synchronously. When the two second sliding plates 326 carry the material tray 500, they can drive the material tray 500 to move. The second translation transmission part 324 can adopt transmission methods such as chain wheels or belt wheels, which are not limited herein.

[0069] Specifically, the distance between the two second slide plates 326 is smaller than the size of the tray 500. When the two second slide plates 326 are located on the Nth layer of the first baking area 11, the tray 500 placed on the (N - 1)th layer of the second baking area 12 cannot move to the Nth layer through the space between the two second slide plates 326. The tray 500 placed on the (N - 1)th layer of the second baking area 12 can move to the Nth layer through the space between the two second guide rails. For the specific moving process, reference can be made to the foregoing description. The bottom of the tray 500 moving to the Nth layer will abut against the upper part of the tray 500 moving to the (N - 1)th layer. At this time, the second translation driving part 321 can drive the two second slide plates to slide towards the second baking area 12. The two translation guide wheels 328 close to the second baking area 12 will first contact the bottom of the tray 500 placed on the Nth layer of the second baking area 12. Then, under the drive of the second translation driving part 321 and the guidance of the two translation guide wheels 328 in contact with the tray 500, the two second slide plates 326 will slide on the corresponding second guide rails 325 and gradually lift the tray 500 until the tray 500 is carried on the two second slide plates 326. Then, the second translation driving part 321 can drive the two second slide plates 326 to drive the tray 500 to move to the Nth layer of the first baking area 11.

[0070] In some embodiments, the support assembly 4 includes a first support member 41 and a second support member 42. The first support member 41 is disposed on the second layer of the first baking area 11. The first support member 41 is used to support at least the tray 500 on the second layer of the first baking area 11. The second support member 42 is at least partially disposed on the second layer of the second baking area 12. The second support member 42 is used to support at least the tray 500 on the second layer of the second baking area 12. As described above, starting from the third layer, the upper tray 500 can abut against the lower tray 500 (the Nth layer may or may not abut). Therefore, by supporting the tray 500 on the second layer, the support assembly 4 also supports the trays 500 on other layers.

[0071] As Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the first support member 41 includes a plurality of (four in this embodiment) first self-locking support portions 410. The four first self-locking support portions 410 are respectively disposed on both sides of the second layer of the first baking area 11. When the tray 500 moves from the first layer to the second layer of the first baking area 11, the four first self-locking support portions 410 open to allow the tray 500 to pass through. The first self-locking support portion 410 is configured to support at least the tray 500 on the second layer of the first baking area 11. The second support member 42 includes two second support portions 420 arranged in parallel and spaced apart from each other and extending along both sides of the second layer of the second baking area 12. Second protruding blocks 421 are respectively provided at both ends of the two second support portions 420. The four second protruding blocks 421 have a telescopic function to allow the tray 500 to pass through when moving between the first layer and the second layer of the first baking area 11, and are configured to support at least the tray 500 on the second layer of the second baking area 12 when extended.

[0072] Specifically, each of the four first self-locking support portions 410 includes a first support frame 411, a first self-locking block 412, and a first elastic member (not shown). The four first support frames 411 are respectively disposed at the four corners of the first layer of the first baking area 11. The upper portions of the four first support frames 411 are close to the second layer of the first baking area 11. The lower ends of the four first self-locking blocks 412 are rotatably mounted on the corresponding first support frames 411. The upper ends of the four first self-locking blocks 412 are located on the second layer. First support surfaces 4121 are respectively provided at the upper ends of the four first self-locking blocks 412. A first guiding surface 4120 is provided between the upper and lower ends of the four first self-locking blocks 412. The four first elastic members are respectively connected to the corresponding first self-locking blocks 412 and the first support frames 411. Under the action of the corresponding first elastic members, the four first self-locking blocks 412 are inclined inward correspondingly. At this time, the four first support surfaces 4121 can support the tray 500 on the second layer of the first baking area 11. When the tray 500 on the first layer of the first baking area 11 moves upward driven by the first support plate 210, the upper part of the tray 500 on the first layer first contacts the lower parts of the four first guiding surfaces 4120, and while moving upward along the four first guiding surfaces 4120, the four first self-locking blocks 412 are pushed to rotate against the acting forces of the corresponding first elastic members, allowing the tray 500 to gradually pass through and move to the second layer. When the tray 500 leaves the upper parts of the first guiding surfaces 4120, the four first self-locking blocks 412 rotate and reset under the acting forces of the corresponding first elastic members. The four first support surfaces 4121 all contact the bottom of the tray 500 and support the tray 500.

[0073] Specifically, the two second support portions 420 extend along the third direction (Figure 1 They are symmetrically arranged in the second baking area 12 in the Y direction (the middle Y direction). Wherein, the third direction is the width direction of the oven 1. The second support portion 420 includes a second support driving plate 422, and the second support driving plate 422 is extended and arranged on the second layer of the second baking area 12 through two second support columns. Both ends of the second support driving plate 422 are respectively provided with protruding guide grooves 4220. The two protruding guide grooves 4220 of the second support driving plate 422 both have a first end 4221 and a second end 4222. The first end 4221 is farther from the first baking area 11 than the second end 4222, and the first end 4221 is farther from the side of the oven 1 in the width direction than the second end 4222. Protruding guide rods 4210 are provided on the upper parts of the four second protruding blocks 421, and the protruding guide rods 4210 of the four second protruding blocks 421 are respectively installed in the corresponding protruding guide grooves 4220. The second support driving plate 422 moves along the first direction, so that the corresponding two protruding guide rods 4210 selectively slide between the first end 4221 and the second end 4222 of the corresponding protruding guide groove 4220, and drive the corresponding second protruding blocks 421 to synchronously protrude or retract along the third direction through the four protruding guide rods 4210. When the protruding guide rod 4210 is at the first end 4221 of the protruding guide groove 4220, the second protruding block 421 is in the protruding state, and the four second protruding blocks 421 can be used to support the tray 500 on the second layer of the second baking area 12; when the protruding guide rod 4210 is at the second end 4222 of the protruding guide groove 4220, the second protruding block 421 is in the retracted state, and the tray 500 can move back and forth between the bottom layer and the second layer of the second baking area 12.

[0074] The moving assembly 2 further includes a lifting guide member, and the lifting guide member is extended and arranged between the second layer and the Nth layer of the oven 1 and is located in the middle of the first baking area 11 and the second baking area 12. The lifting guide member is used for guiding the tray 500 when it moves back and forth between the second layer and the Nth layer.

[0075] Specifically, the lifting guide member includes a lifting guide portion and a guide mounting frame. Both ends of the guide mounting frame are respectively mounted on the two first support columns close to the second baking area 12 along the width direction, and the lifting guide portion is mounted in the middle of the guide mounting frame along the second direction. Both ends of the tray 500 are respectively provided with a first lifting guide wheel pair, and both sides of the lifting guide portion along the first direction are provided with lifting guide grooves matching the first lifting guide wheel pair. When the tray 500 moves back and forth between the second layer and the N-1 layer of the first baking area 11 or the second baking area 12, the first lifting wheel pair at one end can slide in the lifting guide groove.

[0076] The embodiment of the present application also provides a baking method, which uses the above-mentioned baking device 100. The baking method includes the following steps:

[0077] S10: Move the trays 500 on the first layer to the N-1 layer of the first baking area 11 up by one layer;

[0078] S20: Move the tray 500 on the first layer of the second baking area 12 to the loading position 400, remove the baked material 600 on the tray, and transfer the material 600 to be baked to the tray 500;

[0082] S50: Move the trays 500 on the second layer to the Nth layer of the second baking area 12 down by one layer.

[0083] Specifically, steps S10 to S50 are used for the cyclic feeding and discharging of the baking device 100, and are applicable when all the trays 500 in the first baking area 11 and the second baking area 12 are empty, or when some or all of the trays 500 carry the material 600. The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
