Abstract: An oven and an adjustable baking system are proposed. The oven includes a signal receiving module, a baking module, a detecting module, and a feedback module. The signal receiving module is used for receiving a ready-to-send signal sent by a developing apparatus in a previous process from the oven. The ready-to-send signal conveys information of preparing for transferring a glass substrate to the oven. The detecting module is used for detecting the robot to see if the robot takes the glass substrate out of the baking module. The feedback module is used for determining if a confirmation signal is sent back to the developing apparatus according to the detecting result from the detecting module. The confirmation signal conveys information that the developing apparatus should transfer the glass substrate to the feedback module.
