Referring to fig. 4 to 6 and 12, the temperature control module 5 is disposed on the inner wall unit 31 for controlling the temperatures of the heating chamber C1 and the cooling chamber C2.

The blower plate 511 has a plurality of blower holes 511A formed therethrough, and has three layered regions, which are an upper region 511A, a middle region 511B, and a lower region 511C, respectively. Each adjusting plate 512 penetrates through a plurality of adjusting holes 512a, and three adjusting plates 512 are correspondingly arranged in each layered area. The heating element 513 includes a fixing seat 513a disposed on the first sidewall 323 and a plurality of electric heating tubes 513b, and is operable to heat an air flow passing through the heating element 513, the upper filtering element 514 includes a square frame and a plurality of filtering screens (not shown) disposed therein, the upper cooling element 515 may be, for example, a cooling coil having a plurality of fins, and is operable to cool an air flow passing through the upper cooling element 515, the upper cooling element 515 is communicated with a plurality of cooling water pipelines (not shown), and a power source of the cooling water pipelines is the hydraulic pump 6. The adjusting plate 512 can cover a part of the area of the air blowing holes 511a, and the adjusting plate 512 can move up and down relative to the air blowing plate 511, thereby adjusting the air output of each air blowing hole 511a, as shown in fig. 15. In the case shown in fig. 14, the adjusting holes 512a and the blowing holes 511a are all in a superposed state, that is, each blowing hole 511a is not blocked, but in practice, the amount of airflow blown out through the blowing hole 511a located at the central height is slightly higher than the amount of airflow blown out through the blowing holes 511a located at the upper height and the lower height, so that the user moves the adjusting plate 512 located at the central height to block a part of the area of the blowing hole 511a located at the central height, so as to reduce the air output. In the present embodiment, the layered regions are three regions, i.e., an upper layer region 511A, a middle layer region 511B and a lower layer region 511C, but the present invention is not limited thereto.

Referring to fig. 4, 5 and 8, the upper air blowing device 52 is used for blowing the air flow to the heating chamber C1 through the temperature control device 51, each of the upper air blowing devices 52 includes a wind wheel 521 disposed between the inner top wall 311, the upper outer side wall 316 and the outer top wall 317 and a motor 522 for driving the wind wheel 521 to rotate, and the wind wheel 521 has a housing communicated with the temperature control device 51 and blades located inside the housing. Each of the upper temperature sensors 55 is disposed adjacent to the air blowing plate 511 and located in the heating chamber C1, and has three vertically spaced branch portions 551 for sensing the temperatures of the air flow blown out by the air blowing plate 511 at three relative height positions of the upper layer, the middle layer and the lower layer to determine whether the temperature rise curves of the temperature change with time are consistent in the heating process, and if the temperature rise curves are inconsistent, a temperature control method is performed to make the temperature rise curves approach to consistency. The heating member 57 can be, for example, a U-shaped electric heating tube 513b, which is used to heat the space between the inner top wall 311 and the outer top wall 317 during the baking process, so that the temperature of the air blown from the upper air blowing device 52 to the temperature control device 51 is increased, and the time consumed by heating can be shortened.

Referring to FIG. 17, the temperature control method described above is described as follows, which includes steps S1-S4.

Step S1: first, the temperature sensors 55 measure the temperatures of the upper, middle and

lower regions

511A, 511B and 511C of the blower plate 511, respectively, to generate three temperature signals.

Step S2: after receiving the temperature signal, the controller 58 calculates a difference value of the temperature signal, so as to know which of the upper layer 511A, the middle layer 511B and the lower layer 511C has a higher or lower temperature.

Step S3: the controller 58 transmits an adjustment signal to a plurality of corresponding at least one delamination zone of the electrothermal tubes 513b of the heating element 513 to adjust the power of the electrothermal tubes 513b in the at least one delamination zone. For example, if the temperature signal corresponding to upper zone 511A is lower than the other two, the adjustment signal is transmitted to the thermal heating tube 513b corresponding to upper zone 511A to increase the power of the thermal heating tube 513 b. For example, if the temperature signal corresponding to the middle zone 511B is higher than the other two, the adjustment signal is transmitted to the electrothermal tube 513B corresponding to the middle zone 511B, so as to reduce the power of the electrothermal tube 513B. It should be noted that the adjusting signal can also be transmitted to the electrothermal tube 513b corresponding to the upper layer 511A and the lower layer 511C, so as to increase the power of the electrothermal tube 513b, and also reduce the difference value of the temperature signals.

In step S4, it is determined that the difference between the temperature signals is smaller than a default value, which may be, for example, 1 ℃, but not limited thereto, and the default value can be adjusted according to the user' S requirement. If the difference value of the temperature signals is greater than 1 ℃, the step S1 is returned to repeat the above steps until the difference value of the temperature signals is less than 1 ℃, so as to complete the steps of the temperature control method. The temperature control method can make the temperatures of the upper layer area 511A, the middle layer area 511B and the lower layer area 511C consistent, so that the temperature rise curves of the heating chamber C1 are consistent, and the heating effect is more uniform.

Referring to fig. 4, 6 and 9, each of the cooling devices 53 has an air guiding plate 531 penetrating through the corresponding first sidewall 323, a lower filtering member 532 disposed at an interval on a side of the air guiding plate 531 away from the first sidewall 323, and a lower cooling member 533 disposed on a side of the lower filtering member 532 away from the first sidewall 323. The air guiding plate 531 has a plurality of horizontally extending elongated air outlets 531a and a plurality of pairs of funnel-shaped guide bars 531b extending upward and downward from the upper and lower sides of the air outlets 531a, respectively, and the height position of the air outlets 531a is substantially the same as that of the substrate 1, so that the cooling air blown out through the air outlets 531a can be directly blown toward the substrate 1 for cooling. The lower filter 532 and the lower cooling element 533 are identical to the upper filter 514 and the upper cooling element 515, and thus are not described in detail. The lower air blowing devices 54 are used for blowing the air flow into the cooling chamber C2 through the cooling device 53, each lower air blowing device 54 includes a wind wheel 541 disposed between the inner bottom wall 314, the lower outer sidewall 318 and the outer bottom wall 319, and a motor 542 driving the wind wheel 541 to rotate, and the wind wheel 541 has a casing communicating with the cooling device 53 and fan blades located inside the casing. Each of the lower temperature sensing members 56 and each of the upper temperature sensing members 55 are the same element, and are disposed adjacent to the air guiding plate 531 and located in the heating chamber C1, and have three vertically spaced branch portions 561 for sensing the temperatures of the air flow blown out by the air guiding plate 531 at three relative height positions of the upper layer, the middle layer and the lower layer, so as to determine whether the cooling curves of the temperatures varying with time in the cooling process are consistent.

The operation flow of the oven 100 of the present invention is as follows: referring to fig. 7 and 11, the in-out valve 325 is moved downward to open the access port 324a, the substrates 1 are fed into the carrier 2 in the cooling chamber C2 one by one through the access port 324a and the inner opening 313a by, for example, a material taking mechanism (not shown), after the substrates 1 are all conveyed to the carrier 2, the in-out valve 325 is moved upward to close the access port 324a, and then the lower blowing device 54 externally connected with a nitrogen pipeline (not shown) injects nitrogen into the cooling chamber C2, because the baking temperature of the oven 100 of the present invention is at a high temperature of about 300 ℃, if the oxygen content is too high, the substrates 1 are easily oxidized and damaged during the baking process, and thus the oxygen content is reduced by injecting nitrogen. When the oxygen content in the cooling chamber C2 is lower than the standard value, the pushing member 42 of the lifting mechanism 4 drives the lifting table 41 to move upward from the lowered position to the raised position, so that the substrate 1 enters the heating chamber C1 for baking. Referring to fig. 5, before the substrate 1 enters the heating chamber C1, the heating chamber C1 is pre-heated to about 100 ℃ and filled with nitrogen gas through the upper blowing device 52 connected to an external nitrogen pipeline (not shown) to make the oxygen content lower than a standard value, so that heating from room temperature is not required during baking, heating time is saved, heating efficiency is improved, the upper blowing device 52 blows air to the temperature control device 51, the heating element 513 starts to operate to heat the passing air, and the air enters the heating chamber C1 through the blowing holes 511a of the blowing plate 511 to heat the heating chamber C1 and the substrate 1 to 300 ℃. After baking, the heating element 513 stops, the upper cooling element 515 starts to operate to cool the heating chamber C1 and the substrate 1 to 100 ℃, after cooling, the pushing element 42 of the lifting mechanism 4 drives the lifting table 41 to move downward from the raised position to the lowered position, then the lower air blowing device 54 injects cold air at normal temperature into the cooling chamber C2 to cool the substrate 1, after the substrate 1 is cooled to normal temperature, the in-out valve 325 moves downward to open the access 324a, the substrate 1 is cooled from the carrier 2 in the chamber C2 one by, for example, the material taking mechanism (not shown) through the access 324a and the inner opening 313a, and thus the baking process of the oven 100 of the present invention is completed. It should be noted that, since the heating chamber C1 and the cooling chamber C2 are separated by the top plate or the bottom plate of the elevating platform 41 no matter the elevating platform 41 is at the descending position or the ascending position, the baking heating and cooling operations can be performed in the heating chamber C1 and the cooling chamber C2 respectively without mutual influence, and the nitrogen gas injection operation is also performed, so that the time required for each step can be saved, and the overall working efficiency can be effectively improved.

As described above, by the lifting/lowering mechanism 4, the heating chamber C1 and the cooling chamber C2 are separated by the top wall 411 or the bottom wall 412 of the lifting/lowering mechanism 41 no matter the lifting/lowering mechanism 41 is at the lowered position or the raised position, the flow of baking the substrate 1 can be completed in the heating chamber C1, and the substrate 1 is transferred to the cooling chamber C2 through the lifting/lowering mechanism 41 after baking is completed, so that only the heating chamber C1 needs to be heated, and the completed cooling process is completed in the cooling chamber C2, and the heating chamber C1 does not need to be cooled, so that the heating chamber C1 can be maintained at a high temperature, the time consumed by the next heating and temperature rise is reduced, the time consumed by cooling and temperature reduction is reduced because only the cooling chamber C2 needs to be cooled, and the overall efficiency can be effectively improved, thereby achieving the object of the present invention.
