[0002] In recent years, with the rapid development of the optical display device industry, the demand for precision processing of reflectors, as the core components of backlight modules, is increasing. Traditional reflector cutting production lines generally use negative pressure adsorption or vibration screening to collect waste, but there are significant technical defects in actual applications: first, the irregular debris generated by cutting is easy to accumulate in the adsorption pipe, resulting in some waste residue; second, the unclassified mixed waste requires a secondary sorting process, which adds 15%-20% additional processing costs. Therefore, to address the above problems, a reflector cutting production line with automatic waste collection and a control method thereof are proposed. Summary of the Invention

The outer side of the guide column is in contact with the groove wheel. The inner side of the groove wheel is installed with a rotating shaft, and the outer side of the rotating shaft is installed with a bracket. The number of the brackets is equal to the number of sliding grooves in the groove wheel.

[0007] Preferably, the deflector is in the shape of a hollow inverted truncated cone as a whole, and a protective edge is installed on the top of the deflector, and the protective edge is in the shape of a hollow truncated cone as a whole, and the connection between the protective edge and the deflector is rounded; A fixing frame is installed below the deflector cover, the fixing frame is connected to the cutting machine through a first electric telescopic rod, and a connecting frame is installed at the other end of the fixing frame.

[0013] A control method for a reflective sheet cutting production line capable of automatic waste collection comprises the following steps: Step 1: Loading process: First, place the first reflective sheet to be processed on the upper side of the first conveyor belt, and then start the conveying motor. When the conveying motor rotates, it drives the turntable at the end of the main shaft to rotate, and then drives the guide column on the turntable to rotate. The rotation of the guide column drives the groove wheel to rotate intermittently, and then drives the rotating shaft to rotate intermittently, thereby driving the lower bracket and the outer electric suction cup to rotate, so that the electric suction cup can rotate intermittently. When the electric suction cup rotates, it drives the electric suction cup to move up and down through the second electric telescopic rod, so as to facilitate the fixation and removal of the first reflective sheet, and then facilitates the rotation to the upper side of the cutting machine for subsequent cutting processing; Step 2: Cutting: When the electric suction cup moves the absorbed first reflective sheet to the upper side of the cutting machine, the cutting machine is started. Then, under the joint action of the fixed frame, the first electric telescopic rod of the connecting frame and the rear mechanical arm, the cutting machine can cut the first reflective sheet in a pre-set manner. The cut waste will fall by gravity. The second reflective sheet formed after cutting will move to the upper side of the second conveyor belt when the bracket rotates. Then, through the cooperation of the second electric telescopic rod and the electric suction cup, it will be placed on the second conveyor belt and then transported and collected. Step 3: Classification and collection of waste: The debris dropped in step 2 will be guided by the protective cover and the guide cover to ensure that it can fall to the inner side of the centrifugal separation and collection structure below, and then the control motor of the centrifugal separation and collection structure will be started to drive the inner cylinder to rotate, while the outer cylinder is fixed by the collection bag connected to the outside to ensure that it will not rotate. When the inner cylinder rotates, the waste will be thrown onto the side wall of the inner cylinder due to centrifugal force, and then thrown to the inside of the discharge hole through the through hole opened on the inner cylinder, and then collected. The larger waste cannot pass through the smaller through hole on the lower side, and then will continue to move upward due to centrifugal force, and then be discharged through the larger discharge hole on the upper side, thereby achieving the effect of classified collection.

In the present invention, the centrifugal separation and collection structure is provided, which can not only effectively collect and process the cut debris, but also automatically classify and collect the debris according to its volume, thereby facilitating subsequent processing; 2.
