System and method for determining whether to clean a reflow oven
Disclosed example systems for determining whether to clean a reflow oven include: an image acquisition device, a processing unit, and a determining unit. The image acquisition device acquires an image of the interior of the reflow oven when the reflow oven is in a closed state, and stores the acquired image. The image acquisition device is conveyed through a reflow oven chamber of the reflow oven to acquire the image of the interior of the reflow oven. The image of the interior of the reflow oven comprises an image of a surface of a reflow oven chamber device and/or an image of a rail adjustment device. The processing unit processes the stored image to obtain a cleanliness condition of the interior of the reflow oven. The determining unit determines whether the reflow oven needs to be cleaned based on the obtained cleanliness condition of the interior of the reflow oven.
