A use method of a feeding mechanism for a CCD-positioned automatic laminating machine is suitable for the feeding mechanism and comprises the following steps:
s1: firstly, the motor 3 drives the rotary column 2 to rotate clockwise, so that the conveying cavity 4 on the rotary column 2 moves to the top end of the middle part of the rotary column 2;
s2: then, an external manipulator is utilized to place the binding surface of the base material on the top of the conveying cavity 4 towards the lower part, so that the base material falls on the communicating groove 5 of the conveying cavity 4, meanwhile, the air exhaust assembly works and exhausts the inside of the conveying cavity 4 loaded with the base material, so that external air flows into the air exhaust assembly through the communicating groove 5 and the conveying cavity 4, and dust and impurities on the bottom surface of the base material are sucked; therefore, the binding surface of the base material can be effectively cleaned, and the condition that the base material is poorly bound in the subsequent binding process is reduced;
s3: subsequently, the motor 3 continues to rotate, and gradually conveys the base material in the conveying cavity 4 to the bottom end of the rotary column 2, so that the inner base material can fall on the conveying belt, and the subsequent attaching work is carried out.
During operation, the motor 3 drives the rotary column 2 to rotate clockwise, so that the conveying cavity 4 on the rotary column 2 moves to the top end of the middle part of the rotary column 2, then the bonding surface of the substrate faces downwards and is placed at the top of the conveying cavity 4 by utilizing structures such as an external manipulator and the like, at the moment, the substrate can fall on the communicating groove 5 of the conveying cavity 4, then the air exhaust assembly works and exhausts the inside of the conveying cavity 4 loaded with the substrate, so that external gas flows into the air exhaust assembly through the communicating groove 5 and the conveying cavity 4, and dust and impurities on the bottom surface of the substrate are sucked, thereby the bonding surface of the substrate can be effectively cleaned, the condition that the substrate is poorly bonded in the subsequent bonding process is reduced, then the motor 3 can gradually convey the substrate in the conveying cavity 4 to the bottom end of the rotary column 2 when continuing to rotate, and in the process, the arc-shaped plate 6 can block the cavity opening of the conveying cavity 4 in the moving state, the condition that the base material falls from a cavity opening at a high position in the process of rotating along with the conveying cavity 4 to cause damage is avoided, when the conveying cavity 4 loaded with the base material moves to the bottom end of the rotary column 2, the arc-shaped plate 6 does not block the cavity opening of the conveying cavity 4 at the moment, so that the base material in the conveying cavity can stably fall on a conveying belt, and meanwhile, the binding surface of the base material can face upwards, and the subsequent base material can be conveniently and effectively bound; when the conveying cavity 4 moves to the top end of the middle part of the rotary column 2, the connecting groove 10 on the conveying cavity 4 can be just aligned with and communicated with the top end of the communicating pipe 9, then the air pump can pump air inside the conveying cavity 4 through the communicating pipe 9 and the connecting groove 10 during working, so that the effect of cleaning the binding surface of the base material is achieved, through the structure of the air pumping assembly, the air pumping assembly can effectively pump the conveying cavity 4 rotating to the top end of the rotary column 2, the air pumping assembly does not need to be arranged in each conveying cavity 4, and the internal structure of the feeding mechanism is greatly simplified;

when the funnel-shaped cavity 15 is clamped with the connecting part 16, the clamping groove 20 is aligned with the groove 18, and when the air pump works, the elastic membrane 19 bulges into the clamping groove 20 when the negative pressure state is in the funnel-shaped cavity 15, so that the elastic membrane 19 positioned in the groove 18 and the clamping groove 20 can play a more effective blocking effect between the funnel-shaped cavity 15 and the connecting part 16, and the condition that the suction force in the conveying cavity 4 is insufficient due to the fact that external air flows into the funnel-shaped cavity 15 is further reduced; the arranged baffle plates 22 can limit the flowing direction of the airflow, so that the airflow can flow along the baffle plates 22 after flowing in from the communicating groove 5 and flow out from the gap between the two baffle plates 22, thereby being capable of cleaning dust and impurities on the surface of the base material more fully and further improving the cleaning effect of the surface of the base material; through the arranged guide block 23, dust and impurities sucked into the conveying cavity 4 can be more fully sucked into the connecting groove 10 under the guide action of the guide block 23, and the condition that the rotary column 2 drives the dust to be contacted and adhered with the surface of the base material again in the subsequent rotation due to the fact that part of the impurities remain in the conveying cavity 4 is reduced; the cleaning piece 24 can be made of flexible materials, when the interior of the conveying cavity 4 is in a negative pressure state, the cleaning piece 24 can rotate under the action of air flow between the baffle 22 and the substrate, and the adhering surface of the substrate can be scraped, so that the surface of the substrate can be cleaned more effectively; when the cleaning piece 24 rotates clockwise under the action of the airflow, the substrate can gradually press the sliding plate 26 into the sliding cavity 25, so that the overall length of the cleaning piece 24 can be changed in a limited manner, the cleaning piece 24 can rotate smoothly, and meanwhile, the sliding plate 26 can drive the cleaning block 28 to be pressed on the surface of the substrate more durably under the action of the elastic body 27, so that the surface of the substrate can be swept in a larger area, and the cleaning effect of the surface of the substrate is further improved; slide 26 can drive roller 29 and roll on the substrate surface and drive clearance piece 24 motion, the frictional resistance between clearance piece 24 and the substrate has been reduced greatly, simultaneously slide 26 is when the inside slip of slide 25 under the extrusion of substrate, the gas in slide 25 can flow into rolling gas outlet groove 30 through pressure relief groove 31 this moment, thereby can follow direct injection in gas outlet groove 30 on the substrate surface, the clearance effect on substrate surface has further been improved, and the pressure relief groove 31 that sets up can make in the slide 25 by the timely discharge of extruded gas, reduce the resistance when slide 26 slides to slide 25 inside, simultaneously go out the gas flow of spun in the gas outlet groove 30 and can blow off the impurity on clearance piece 28, make the dust impurity that drops on the substrate can more effectively be collected.
