The invention discloses sputtering coating equipment and a stopping and starting method for a conveying mechanism of the sputtering coating equipment. The sputtering coating equipment comprises functional chambers, the conveying mechanism and two protective doors, the functional chambers are arranged on the side face of the conveying mechanism, the two protective doors are arranged on the two sides of the conveying mechanism and each provided with a one-key stopping button and a one-key starting button to control starting and stopping of the conveying mechanism, and meanwhile the protective doors can be opened only when the conveying mechanism completely stops. The sputtering coating equipment has the beneficial effects that the one-key stopping buttons and the one-key starting buttons arearranged on the two protective doors, one-key starting and stopping of the conveying mechanism can be achieved when a worker passes through the conveying mechanism, therefore, the safety of the worker is guaranteed, and the time that production is stopped when a sputtering coating machine is maintained and repaired is shortened.
