Abstract

The present application provides an oven drying apparatus and a coating device. The oven drying apparatus comprises an oven drying chamber and a heating assembly. The oven drying chamber is equipped with a first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber. The heating assembly is disposed on the first oven drying side. The first oven drying side is further provided with at least one air return portion provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber. The arrangement of an air return portion between two first air inlet portions can discharge fluid medium between the two first air inlet portions and take away the heat, thus avoiding accumulation of heat between the two first air inlet portions.

First claim

The invention claimed is:

An oven drying apparatus, comprising: an oven drying chamber for accommodating a to-be-oven-dried member, the oven drying chamber having a first oven drying side facing the to-be-oven-dried member, with the first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber; and a heating assembly disposed on the first oven drying side, the heating assembly being configured to oven-dry the to-be-oven-dried member; wherein the first oven drying side is further provided with an air return portion, at least one air return portion being provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber,
wherein the first air inlet portions, the heating assembly, and the air return portion are disposed on a same side of the to-be-oven-dried member, and
wherein the oven drying chamber further has a second oven drying side arranged opposite to the first oven drying side in a first direction, the second oven drying side being provided with a plurality of second air inlet portions for fluid medium to enter the oven drying chamber.

2. The oven drying apparatus according to claim 1 , wherein the oven drying apparatus comprises a first wall facing the to-be-oven-dried member in a first direction, the first air inlet portions, the heating assembly, and the air return portion being all disposed on the first wall; and the oven drying apparatus further comprises a first driver to adjust a distance between the first wall and the to-be-oven-dried member in the first direction.

3. The oven drying apparatus according to claim 1 , wherein the oven drying apparatus further comprises a first air inlet chamber, the first air inlet chamber being separated from the oven drying chamber by a first wall, the first air inlet portions, the heating assembly, and the air return portion being all disposed on the first wall; wherein the first air inlet portions are used for fluid medium in the first air inlet chamber to enter the oven drying chamber.

4. The oven drying apparatus according to claim 3 , wherein the oven drying apparatus further comprises an air return chamber and a circulator, the air return chamber being configured to accommodate fluid medium discharged from the air return portion and the circulator being configured to import fluid medium in the air return chamber into the first air inlet chamber.

5. The oven drying apparatus according to claim 1 , wherein the oven drying apparatus comprises a first wall facing the to-be-oven-dried member in the first direction and a second wall arranged opposite to the first wall; the first air inlet portions, the heating assembly, and the air return portion being all disposed on the first wall and the second air inlet portions being disposed on the second wall; the oven drying chamber being located between the first wall and the second wall in the first direction; and the oven drying apparatus further comprises a second driver to drive the second wall to move to adjust a distance between the second wall and the first wall in the first direction.

6. The oven drying apparatus according to claim 1 , wherein at least one heating assembly is provided between two adjacent first air inlet portions.

7. The oven drying apparatus according to claim 1 , wherein the oven drying apparatus comprises an air blowing structure to provide fluid medium to the heating assembly to adjust a temperature of the heating assembly.

8. The oven drying apparatus according to claim 7 , wherein the heating assembly comprises a mounting bracket and a heater, the mounting bracket being disposed on the oven drying side, and the heater and the air blowing structure being both disposed on the mounting bracket.

9. The oven drying apparatus according to claim 8 , wherein the heating assembly further comprises a guard disposed on the mounting bracket and enclosing an outer periphery of the heater.

10. The oven drying apparatus according to claim 1 , wherein a distance between one of the two first air inlet portions and the air return portion is equal to another distance between another one of the two first air inlet portions and the air return portion.

11. A coating device, comprising: a coating apparatus configured to coat a substrate; and the oven drying apparatus according to claim 1 , which is used for oven-drying a coating coated on the substrate.

12. The coating device according to claim 11 , wherein the coating apparatus comprises a first coating structure and a second coating structure, the second coating structure being disposed downstream of the first coating structure, and the first coating structure being configured to coat a first surface of the substrate and the second coating structure being configured to coat a second surface of the substrate that is opposite to the first surface; and the coating device comprises two oven drying apparatuses, one of the two oven drying apparatuses being disposed downstream of the first coating structure and located upstream of the second coating structure to oven dry a coating on the first surface, and the other of the two oven drying apparatuses being located downstream of the second coating structure to oven dry a coating on the second surface.

13. The coating device according to claim 12 , wherein the coating device further comprises a heating apparatus, the heating apparatus being disposed downstream of the oven drying apparatus located downstream of the second coating structure, and the heating apparatus being configured to oven dry the coating on the second surface.

14. An oven drying apparatus, comprising: an oven drying chamber for accommodating a to-be-oven-dried member, the oven drying chamber having a first oven drying side facing the to-be-oven-dried member, with the first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber; and a heating assembly disposed on the first oven drying side, the heating assembly being configured to oven-dry the to-be-oven-dried member; wherein the first oven drying side is further provided with an air return portion, at least one air return portion being provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber,
wherein the oven drying chamber further has a second oven drying side arranged opposite to the first oven drying side in a first direction, the second oven drying side being provided with a plurality of second air inlet portions for fluid medium to enter the oven drying chamber.

15. The oven drying apparatus according to claim 14 , wherein the oven drying apparatus comprises a first wall facing the to-be-oven-dried member in a first direction, the first air inlet portions, the heating assembly, and the air return portion being all disposed on the first wall; and the oven drying apparatus further comprises a first driver to adjust a distance between the first wall and the to-be-oven-dried member in the first direction.
