[0024] The terms such as tray, capacitor, material, etc. herein are for descriptive purposes only and should not be construed as limiting the present application.

[0025] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a baking device 100, which includes an oven 1, a moving component 2 and a supporting component 4. The baking device is used to accommodate multiple stacked trays 500 and bake capacitors and battery cell materials 600 (hereinafter collectively referred to as materials 600) carried on the trays 500. The baked materials 600 can be supplied to the next process. The baking device 100 can be installed separately from related devices (such as an impregnation machine) of subsequent processes, or can be installed together to form a complete set of impregnation equipment, which is not limited here.

[0026] The oven 1 has a plurality of internal parts along the first direction ( Figure 1 The first baking area 11 and the second baking area 12 are adjacent to each other (in the X direction in FIG. 1 ), and the first baking area 11 and the second baking area 12 can accommodate at most N layers of the material trays 500, wherein N is greater than or equal to 2, and the N material trays are stacked up and down in the first baking area 11 and / or the second baking area 12, and at least part of the material trays 500 in the upper layer can abut against the material trays 500 in the lower layer. In this embodiment, the bottom layer of the first baking area 11 and the second baking area 12 is the first layer, and the top layer is the Nth layer for reference 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 material trays 500. A gate 18 that can be opened or closed is provided at the bottom of one side of the oven 1, and a material loading position 400 is provided on the outer side of the gate 18 of the oven 1. The moving assembly 2 is at least partially disposed in the oven 1, and is used to drive the material tray 500 to move along a set path. For example, the material tray 500 can be driven to move along the set path in the first direction ( Figure 1 X direction) and / or the second direction ( Figure 1The first direction is the length direction of the oven 1 (the direction between the first baking zone 11 and the second baking zone 12), and the second direction is the height direction of the oven 1. It can be understood that if the first baking zone 11 is close to the gate 18, the second baking zone 12 is far away from the gate 18; it is also possible that if the second baking zone 12 is close to the gate 18, the first baking zone 11 is far away from the gate 18. The first baking zone 11 and the second baking zone 12 of the oven 1 can accommodate N layers of the material trays 500 at most, that is, the baking box 1 has 2N baking positions, which can be adjusted in actual use, that is, the number of the material trays 500 can be increased or decreased according to actual needs, and there is no limitation here. The maximum number of material trays 500 that can be accommodated in the first baking zone 11 and the second baking zone 12 can be equal or unequal. The loading position 400 can also be used to place the material trays 500 for loading and unloading. For the convenience of description, the following are specific embodiments: (a) the first baking area 11 is close to the gate 18, and the second baking area 12 is far away from the gate 18; (b) the first baking area 11 and the second baking area 12 are described as being equipped with the material tray 500 from the first layer to the N-1 layer; these two descriptions should not be regarded as limitations on the present application.

[0027] In some embodiments, a side of the oven 1 adjacent to the gate 18 is provided with a double door 19 that can be opened or closed. Opening the double door 19 can be used to initially place the material tray 500 on each layer of the first baking zone 11 and the second baking zone 12 of the oven 1, or to open the double door 19 when performing maintenance on the baking device 100. Generally, the double door 19 is closed.

[0028] Specifically, the oven 1 is a box frame closed structure, and the interior is divided into the first baking area 11 and the second baking area 12 adjacent to each other, and the gate 18 is arranged at the bottom of one side of the first baking area 11 of the oven 1. The size of the material tray 500 can match the size of the gate 18. Each layer of the first baking area 11 can accommodate one material tray 500, and a total of N layers of material trays 500 can be accommodated at most. Similarly, the second baking area 12 can also accommodate N layers of material trays 500 at most.

[0029] The supporting assembly 4 is at least partially disposed in the oven 1, and is used to support at least the material tray 500 of the second layer of the first baking zone 11 and / or the second baking zone 12, and to allow the material tray 500 to pass when the moving assembly 2 moves the material tray 500 back and forth between the first layer and the second layer of the second baking zone 12.

[0030] It can be understood that the material tray 500 is used to carry the material 600, so the moving component 2 completes the entry and exit of the material 600 by moving the material tray 500. When the upper material position 400 of the material tray 500 is input into the oven 1 or output from the oven 1 to the upper material position 400, the gate 18 is opened, and when the baking device 100 is baking, the gate 18 is closed. There is a gap between the upper part of the material tray 500 of the first layer and the bottom of the material tray 500 of the corresponding second layer. The bottom of the material tray 500 of the Nth layer can also abut against the material tray 500 of the N-1th layer. When the moving component 2 moves the material tray 500 between the Nth layer of the first baking zone 11 and the second baking zone 12, there is also a gap between the bottom of the material tray 500 of the Nth layer and the upper part of the corresponding material tray 500 of the N-1th layer. The feeding process of the baking device 100 is described below on the assumption that all the material trays 500 in the first baking zone 11 and the second baking zone 12 are empty (ie, not carrying the material 600).

[0031] In the first step, the moving assembly 2 moves the material tray 500 of the first layer of the first baking zone 11 to the upper material position 400, and at the same time, the material tray 500 of the first layer of the second baking zone 12 is moved to the first layer of the first baking zone 11. The first layer of the second baking zone 12 is empty (i.e., no material tray 500 is placed). The material 600 to be baked is transferred to the material tray 500 located at the upper material position 400.

[0032] In the second step, the moving component 2 moves the first layer of the first baking zone 11 and resets the material tray 500 of the upper material position 400, that is, the material tray 500 of the first layer of the first baking zone 11 is moved to the first layer of the second baking zone 12, and the material tray 500 of the upper material position 400 is moved to the first layer of the first baking zone 11.

[0033] In the third step, the moving component 2 moves the material tray 500 (loaded with the material 600 to be baked) of the first layer of the first baking zone 11 to the second layer. When the upper part of the material tray 500 of the first layer abuts against the bottom of the material tray 500 of the second layer, the moving component 2 moves the material tray 500 of the first layer again to push the material trays 500 of each layer above it to move upward. When the material tray 500 of the first layer moves to the second layer, the supporting component 4 allows it to pass and supports it on the second layer. After completing this step, the material trays 500 are all accommodated in the second layer to the Nth layer of the first baking zone 11.

[0034] In the fourth step, the moving assembly 2 lifts the material tray 500 on the Nth layer of the first baking zone 11 and moves it to the Nth layer of the second baking zone 12, and then the moving assembly 2 no longer lifts the material tray 500 to make it abut against the material tray 500 on the N-1th layer of the second baking zone 12. The moving assembly 2 moves the material tray 500 on the first layer of the second baking zone 12 to the first layer of the first baking zone 11.

[0035] In the fifth step, the moving assembly 2 supports the material tray 500 of the second layer of the second baking zone 12 (as can be seen from the above description, it actually supports the material trays 500 of the second layer to the Nth layer), and then the supporting assembly 4 no longer supports the material tray 500 of the second layer and allows it to move downward, and the moving assembly 2 moves the material tray 500 of the second layer of the second baking zone 12 to the first layer, and the other layers will move down one layer, that is, the material tray 500 of the third layer will move to the second layer and be supported by the supporting assembly 4. At this time, the first layer to the N-1th layer of the first baking zone 11 and the second baking zone 12 are all equipped with the material tray 500, but at this time, the material tray 500 of the second layer of the first baking zone 11 carries the material 600 to be baked.

[0036] Step 6: Repeat Steps 1 to 5 until all the material trays 500 on each layer are loaded with the materials 600 to be baked. At this time, the materials 600 on the first layer of the material tray 500 in the second baking zone 12 are loaded first, and so on. The materials 600 on the first layer of the material tray 500 in the first baking zone 11 are loaded last. Then, the baking device 100 can be started to bake for a first predetermined time.

[0037] The following continues to describe the loading and unloading of materials during the baking process of the baking device 100 .

[0038] In the seventh step, the moving component 2 moves the material tray 500 of the first layer of the first baking zone 11 to the second layer. The second layer to the Nth layer of the first baking zone 11 all have the material tray 500. The moving component 2 moves the material tray 500 of the first layer of the second baking zone 12 to the first layer of the first baking zone 11.

[0039] In the eighth step, the moving component 2 lifts the material tray 500 of the Nth layer of the first baking zone 11 and moves it to the Nth layer of the second baking zone 12. The moving component 2 supports the material tray 500 of the second layer of the second baking zone 12 and moves it to the first layer. Similarly, it can be known that the other layers will move down one layer. The first layer to the N-1th layer of the first baking zone 11 and the second baking zone 12 are both equipped with the material tray 500, and the material tray 500 is loaded with the material 600. The Nth layer of the first baking zone 11 and the second baking zone 12 is in an empty state. At this time, the material 600 on the material tray 500 of the first layer of the first baking zone 11 is the first to enter the oven 1, and the material 600 on the material tray 500 of the first layer of the second baking zone 12 is the second to enter the oven 1.

[0040] In the ninth step, the gate 18 is opened, and the moving component 2 moves the material tray 500 of the first layer of the first baking zone 11 to the material loading position 400. At the same time, the material tray 500 of the first layer of the second baking zone 12 is moved to the first layer of the first baking zone 11. The gate 18 can be closed to continue baking. The material 600 (the baked material 600) on the material tray 500 of the material loading position 400 is unloaded, and the material 600 to be baked is fully loaded, 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 the gate 18 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 material tray 500 of the first layer of the first baking zone 11 to be reset to the first layer of the second baking zone 12, and the material tray 500 of the material loading position 400 will also be reset to the first layer of the first baking zone 11. At this time, the material 600 on the material tray 500 of the first layer of the second baking zone 12 is the first to enter the oven 1, and the material 600 on the material tray 500 of the first layer of the first baking zone 11 is called the last to enter.

[0041] In the tenth step, the gate 18 is closed, and baking is continued for the second predetermined time, and then the process returns to the seventh step to realize cyclic loading and unloading.

[0042] By arranging the first baking zone 11 and the second baking zone 12 adjacent to each other along the length direction of the oven 1 in the oven 1, each baking zone can accommodate a maximum of N layers of the material trays 500 along the height direction of the oven 1, and the number of layers of the material trays 500 accommodated in each baking zone can be adjusted as needed to reduce the occupied area of ​​the plane site. In addition, the production efficiency is improved by cyclic loading and unloading.

[0043] See also Figure 2In some embodiments, the moving assembly 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 zone 11. The first lifting member 21 is used to move the material tray 500 of the first baking zone 11 from the bottom layer to the top layer in the first baking zone 11. The moving method can be step-by-step, that is, it only moves upward by a 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 used to move the material tray 500 of the second baking zone 12 from the top layer to the bottom layer. The moving method can be step-by-step, that is, it only moves downward by a distance of one layer each time.

[0044] like Figure 4 As shown, further, the first lifting member 21 includes a first support plate 210 and a first lifting drive unit 211, the first support plate 210 is arranged below the first baking area 11, and can be used to lift the tray 500 at the bottom of the first baking area 11, the first lifting drive unit 211 is connected to the first support plate 210, and the first lifting drive unit 211 is used to drive the first support plate 210 to lift the tray 500 of the first layer in the first baking area 11 to the second layer. During this process, the tray 500 of the first layer pushes up the tray 500 of the original second layer, thereby driving the tray 500 above it to move upward one layer in turn. The second lifting member 22 includes a second support plate 220 and a second lifting drive unit 221. The second support plate 220 is arranged below the second baking area 12 and can be used to lift the material tray 500 at the bottom of the second baking area 12. The second lifting drive unit 221 is connected to the second support plate 220. The second lifting drive unit 221 is used to drive the second support plate 220 to move back and forth at least between the first layer and the second layer of the second baking area 12.

[0045] Specifically, the first lifting drive unit 211 is disposed at the bottom of the oven 1 and connected to the first support plate 210. The first lifting drive unit 211 can drive the first support plate 210 to move back and forth between the first layer and the second layer of the first baking zone 11. When the first support plate 210 carries the material tray 500, the first lifting drive unit 211 can drive the first support plate 210 to drive the material tray 500 to move and pass through (pass through) the support assembly 4 to the second layer, and the support assembly 4 supports the material tray 500 on the second layer. Even if the first support plate 210 drops to the first layer, the support assembly 4 can support the material tray 500 on the second layer. It can be seen from the above description that when the first lifting drive unit 211 drives the first support plate 210 to drive the material tray 500 to lift from the first layer to the second layer, the original second layer to the N-1 layer of the first baking zone 11 are correspondingly moved up one layer (the Nth layer of the first baking zone 11, that is, the top layer is in an idle state in advance). Similarly, when the second pallet 220 carries the material tray 500, the second lifting drive unit 221 can drive the second pallet 220 to move the material tray 500 through the support assembly 4 to the second layer. The support assembly 4 supports the material tray 500 on the second layer, and the second lifting drive unit 221 can drive the second pallet 220 to return to the first layer. In addition, when the second pallet 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 material tray 500), the second lifting drive unit 221 can drive the second pallet 220 to rise to the second layer and support the material tray 500 on the second layer and above, and the support component 4 can control the action and no longer support the material tray 500 on the second layer. The second lifting drive unit 221 can drive the second pallet 220 downward to move the material tray 500 on the second layer to the first layer. It can be seen from the above that the original third layer to the N-1th layer are all moved down by one layer (if the Nth layer also accommodates the material tray 500, it will drop to the N-1th layer).

[0046] The first lifting drive unit 211 can be a combination of a motor and a screw pair, that is, the screw of the screw pair is threadedly connected to the first support plate 210, and the motor drives the screw pair to work, and the screw of the screw pair drives the first support plate 210 to rise or fall, thereby driving the material tray 500 to move back and forth (lift and lower) 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, and the piston of the cylinder is connected to the first support plate 210. The extension or retraction of the piston can drive the material 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 support plate 210, which is not limited here. Similarly, the second lifting drive unit 221 can also adopt any of the above-mentioned power mechanisms, which is not limited here.

[0047] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, an upper material position 400 is provided at the gate 18, and the moving assembly 2 also includes a first translation member 31 and a second translation member 32. The first translation member 31 extends through the gate 18 and is arranged at the first layer of the oven 1 and the upper material position 400. The first translation member 31 is used to move the material tray 500 of the upper material position 400 to the first layer of the first baking zone 11, and is used to move the material tray 500 of the first layer of the second baking zone 12 to the upper material position 400. The second translation member 32 is arranged at the side wall of the top layer of the oven 1. Before the first lifting member 21 moves the material trays 500 from the first layer to the N-1 layer upward by one layer, the second translation member 32 is used to drive the material tray 500 of the Nth layer of the first baking zone 11 to the Nth layer of the second baking zone 12.

[0048] The first translation member 31 includes the first translation driving part 311 and two first moving parts 310 spaced in parallel, the first translation driving part 311 is used to drive the two first moving parts 310, the first translation driving part 311, the two first moving parts 310 extend along the first layer of the oven 1 through the gate 18 to the loading position 400, the first translation driving part 311 is connected to the two first moving parts 310 and is used to drive the two to move synchronously. The second translation member 32 includes the second translation driving part 321 and two second moving parts 320 spaced in parallel, the second translation driving part 321 is used to drive the two second moving parts 320, the two second moving parts 320 extend along the side wall of the Nth layer of the oven 1, the second translation driving part 321 is connected to the two second moving parts 320 and is used to drive the two to move synchronously.

[0049] 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 supporting plate 210 is located between the two first moving parts 310 in the first baking area 11, and the position of the first supporting plate 210 is slightly lower than the two first moving parts 310. The second supporting plate 220 is located between the two first moving parts 310 in the second baking area 12, and the position of the second supporting plate 220 is also slightly lower than the two first moving parts 310. When the first lifting drive unit 211 does not drive the first support plate 210 to rise to a position higher than the two first moving parts 310, and the second lifting drive unit 221 does not drive the second support plate 220 to rise to a position higher than the second moving part 320, the first layers of the first baking area 11 and the second baking area 12 are both equipped with the material tray 500, that is, the two first moving parts 310 are located in the first baking area 11 and the second baking area 12 and carry the material tray 500, and the first translation drive unit 311 can drive the first moving part 310 to drive both the material trays 500 to move toward the upper material position 400, that is, the material tray 500 of the first layer of the first baking area 11 moves to the upper material position 400, and the material tray 500 of the first layer of the second baking area 12 moves to the first layer of the first baking area 11. Other situations can also be easily inferred based on the above description, which will not be described here.

[0050] In some embodiments, the two second moving parts 320 each include a second guide rail 325 and a second slide 326 slidably provided on the second guide rail 325, the two second guide rails 325 are respectively extended along the inner side of the Nth layer side walls of the first baking area 11 and the second baking area 12, and translation guide wheels 328 are provided at both ends of the two second slides 326, the material tray 500 can pass between the two second guide rails 325, and the material tray 500 can be carried between the two second slides 326, and the second translation drive part 321 is connected to the two second slides 326, and is used to drive the two second slides 326 to slide on the corresponding second guide rails 325 respectively. The second translation drive unit 321 includes a second translation motor 323 and two second translation transmission units 324. The two second translation transmission units 324 are respectively extended along the inner side of the N-th layer side wall of the first baking area 11 and the second baking area 12, and are respectively spaced parallel to the second guide rails 325 on the corresponding sides. The two second translation transmission units 324 are respectively connected to the second slide plates 326 on the corresponding sides. The second translation motor 323 is connected to both the second translation transmission units 324. When the second translation motor 323 is working, it drives the two second translation transmission units 324 to drive the corresponding second slide plates 326 to slide synchronously. When the two second slide plates 326 carry the material tray 500, they can drive the material tray 500 to move. The second translation transmission unit 324 can be a transmission method such as a chain wheel or a pulley, which is not limited here.

[0051] Specifically, the distance between the two second slides 326 is smaller than the size of the material tray 500. When the two second slides 326 are located at the Nth layer of the first baking zone 11, the material tray 500 accommodated at the N-1th layer of the second baking zone 12 cannot be moved to the Nth layer between the two second slides 326. The material tray 500 accommodated at the N-1th layer of the second baking zone 12 can be moved to the Nth layer between the two second rails. The specific moving process can refer to the above description. The bottom of the material tray 500 moved to the Nth layer will abut against the upper part of the material tray 500 moved to the N-1th layer. At this time, the second translation driving part 321 can drive the two second sliding plates to slide toward the second baking area 12, and the two translation guide wheels 328 near the second baking area 12 will first contact the bottom of the material tray 500 accommodated in the Nth layer of the second baking area 12, and 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 material tray 500, the two second slide plates 326 will slide on the corresponding second guide rails 325 and gradually lift the material tray 500 until the material 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 move the material tray 500 to the Nth layer of the first baking area 11.

[0052] In some embodiments, the support assembly 4 includes a first support member 41 and a second support member 42, wherein the first support member 41 is disposed at the second layer of the first baking zone 11, and the first support member 41 is used to at least support the material tray 500 of the second layer of the first baking zone 11, and the second support member 42 is at least partially disposed at the second layer of the second baking zone 12, and the second support member 42 is used to at least support the material tray 500 of the second layer of the second baking zone 12. As can be seen from the above description, starting from the third layer, the material tray 500 of the upper layer can abut against the material tray 500 of the lower layer (wherein the Nth layer may or may not abut), so the support assembly 4 supports the material trays 500 of the other layers by supporting the material trays 500 of the second layer.

[0053] like Figure 7 , Figure 8 and Fig. 9As shown, in some embodiments, the first support member 41 includes a plurality of (four in this embodiment as an example) first self-locking support portions 410, and the four first self-locking support portions 410 are respectively arranged on both sides of the second layer of the first baking zone 11. When the material tray 500 moves from the first layer of the first baking zone 11 to the second layer, the four first self-locking support portions 410 are opened to allow the material tray 500 to pass through, and the first self-locking support portions 410 are used to at least support the material tray 500 of the second layer of the first baking zone 11. The second support member 42 includes two second support portions 420 spaced in parallel and extending along both sides of the second layer of the second baking zone 12. The two ends of the two second support portions 420 are respectively provided with second extension blocks 421. The four second extension blocks 421 have a telescopic function, so that the material tray 500 passes through when moving between the first layer and the second layer of the first baking zone 11, and are used to at least support the material tray 500 of the second layer of the second baking zone 12 when extended.

[0054] Specifically, the four first self-locking support parts 410 each include 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 arranged at the four corners of the first layer of the first baking area 11, the upper parts 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 installed on the corresponding first support frames 411, the upper ends of the four first self-locking blocks 412 are located on the second layer, the upper ends of the four first self-locking blocks 412 are each provided with a first supporting surface 4121, a first guide surface 4120 is provided between the upper end and the lower end of the four first self-locking blocks 412, the four first elastic members are respectively connected with the corresponding first self-locking blocks 412 and the first support frame 411, the four first self-locking blocks 412 are tilted inwardly under the action of the corresponding first elastic members, and at this time, the four first supporting surfaces 4121 can support the material tray 500 of the second layer of the first baking area 11. When the material tray 500 of the first layer of the first baking area 11 moves upward driven by the first support plate 210, the upper part of the material tray 500 of the first layer first contacts the lower part of the four first guide surfaces 4120, and while moving upward along the four first guide surfaces 4120, pushes the four first self-locking blocks 412 to rotate while overcoming the corresponding force of the first elastic members, so that the material tray 500 gradually moves to the second layer, and the material tray 500 leaves the upper part of the first guide surface 4120, and the four first self-locking blocks 412 are rotated and reset under the action of the corresponding first elastic members, and the four first supporting surfaces 4121 are in contact with the bottom of the material tray 500 and support the material tray 500.

[0055] Specifically, the two second support parts 420 are arranged along the third direction ( Figure 1 The second support portion 420 is symmetrically arranged in the second baking zone 12 along the Y direction. The third direction is the width direction of the oven 1. The second support portion 420 includes a second support driving plate 422, which is extended and arranged on the second layer of the second baking zone 12 through two second support columns, and both ends of the second support driving plate 422 are respectively provided with extension guide grooves 4220. The two extension guide grooves 4220 of the second support driving plate 422 each have a first end 4221 and a second end 4222, the first end 4221 is farther away from the first baking zone 11 than the second end 4222, and the first end 4221 is farther away from the side of the oven 1 in the width direction than the second end 4222. The upper part of the four second extension blocks 421 is provided with an extension guide rod 4210, and the extension guide rod 4210 of each of the four second extension blocks 421 is installed in the corresponding extension guide groove 4220. The second support driving plate 422 moves along the first direction, so that the corresponding two extending guide rods 4210 selectively slide between the first end 4221 and the second end 4222 of the extending guide groove 4220 in the corresponding extending guide groove 4220, and the corresponding second extending block 421 is driven to extend or retract synchronously along the third direction through the extending guide rods 4210. When the extending guide rod 4210 is at the first end 4221 of the extending guide groove 4220, the second extending block 421 is in an extended state, and the second extending block 421 can be used to support the material tray 500 of the second layer of the second baking area 12; when the extending guide rod 4210 is at the second end 4222 of the extending guide groove 4220, the second extending block 421 is in a retracted state, allowing the material tray 500 to move back and forth between the bottom layer and the second layer of the second baking area 12.

[0056] The moving assembly 2 also includes a lifting guide, which extends between the second layer to the Nth layer of the oven 1 and is located between the first baking area 11 and the second baking area 12. The lifting guide is used to guide the material tray 500 when it moves back and forth between the second layer to the Nth layer.

[0057] Specifically, the lifting guide member includes a lifting guide part and a guide mounting frame, the two ends of the guide mounting frame are respectively mounted on the two first support columns close to the second baking zone 12 along the width direction, and the lifting guide part is mounted in the middle of the guide mounting frame along the second direction. The two ends of the material tray 500 are respectively provided with a first lifting guide wheel pair, and the two sides of the lifting guide part along the first direction are provided with lifting guide grooves matching the first lifting guide wheel pair. When the material tray 500 moves back and forth between the second layer and the N-1 layer of the first baking zone 11 or the second baking zone 12, the first lifting wheel pair at one end can slide in the lifting guide groove.

[0058] The embodiment of the present application further provides a baking method, using the above-mentioned baking device 100, and the baking method comprises the following steps: S10: moving the material trays 500 from the first layer to the N-1 layer of the first baking zone 11 upward by one layer; S20: Move the first layer of the material tray 500 of the second baking zone 12 to the material loading position 400, The baked material 600 on the tray is removed, and the material 600 to be baked is transferred to the material tray 500; S30: moving the material tray 500 of the upper material position 400 to the first layer of the first baking zone 11; S40: moving the material tray 500 of the Nth layer of the first baking zone 11 to the Nth layer of the second baking zone 12; S50: moving the material trays 500 from the second layer to the Nth layer of the second baking zone 12 down by one layer.

[0059] Specifically, steps S10 to S50 are used for the cyclic loading and unloading of the baking device 100, which can be applied when all the material trays 500 in the first baking area 11 and the second baking area 12 are empty, or when some or all of the material trays 500 are loaded with the material 600.
