In a specific application, since the kick-out plate 133 has an inertial force, when 2v < v1, the inertial momentum of the kick-out plate 133 is the largest, the rotation speed of the kick-out plate 133 needs to be reduced in advance, and when the first tooth 13312 enters the first groove 1411, the first driving source 131 decelerates to drive the kick-out plate 133, so that the first tooth 13312 decelerates to reach the second groove 1421 and then stops, thus, the control method for stopping the first tooth 13312 in the second groove 1421 by decelerating in advance can control the travel stroke of the chip on the tape more accurately, and the accuracy of positioning the chip in the positioning groove 122 is ensured.
In one possible embodiment, the dial 133 includes a first tooth 13312 and a second tooth 13313 disposed adjacent to the first tooth 13312, the first tooth 13312 and the second tooth 13313 sequentially passing through the first notch 1411 and the second notch 1421 as the dial 133 continues to rotate, and the first tooth 13312 decelerating to stop after reaching the second notch 1421 as the second tooth 13313 enters the first notch 1411 when V < V1 is less than or equal to 2V. In a specific application, when V < V1 is less than or equal to 2V, the inertia momentum of the dial 133 is smaller, and because the dial 133 includes the first tooth 13312 and the second tooth 13313 disposed adjacent to the first tooth 13312, when the dial 133 continuously rotates, the first tooth 13312 and the second tooth 13313 sequentially pass through the first groove 1411 and the second groove 1421, and at this time, when the second tooth 13313 needs to wait for entering the first groove 1411, the first tooth 13312 is decelerated again and then reaches the second groove 1421 to stop, so that the efficiency of stirring the tape by the dial 133 can be improved, and chips cannot be stopped in the positioning groove 122 due to the excessive inertia momentum of the dial 133.
In one possible embodiment, when v1=v, the first tooth 13312 enters the first groove 1411 and then reaches the second groove 1421 at a constant velocity and then stops. In particular, when v1=v, it means that the chip of the tape can meet the response speed of the positioner 140 and stop in the positioning slot 122, so that the first tooth 13312 is controlled to enter the first groove 1411 and then reach the second groove 1421 at a constant speed.
In one possible embodiment, when V1< V, the first tooth 13312 accelerates to a velocity V1 after entering the first groove 1411 and stops after maintaining the velocity V1 to reach the second groove 1421. In a specific application, because there is a friction force between the material stirring disc 133 and the material belt, when V1 is less than V, the first material teeth 13312 enter the first groove 1411 and then are uniformly accelerated to a speed V1, and the speed V1 is kept to reach the second groove 1421 and then stop, so that the efficiency of stirring the material belt by the material stirring disc 133 can be improved, and the efficiency of removing the film of the flying device 100 can be prevented from being influenced.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
