Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
Fig. 1 is the front view of a kind of surface mount elements automatic coiling of tape of the utility model machine;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
As shown in Figure 1, surface mount elements automatic coiling of tape machine comprises support 1, coil paper unit I 2, coil paper unit II 3, winding unit I 4, winding unit II 5 and controller 6.Support 1 bottom is provided with four cardan wheels, and support 1 integral body is convex shape.Coil paper unit I 2 and coil paper unit II 3 are installed in the two ends of support 1 top width minimum, and winding unit I 4 and winding unit II 5 are installed in the two ends of support 1 middle part width maximum.As shown in Figure 2, controller 6 is installed in support 1 bottom, and the input-output equipment on the controller 6 is installed on the support 1 and the position between coil paper unit I 2 and coil paper unit II 3.
Coil paper unit I 2 comprises spool and motor, and spool is connected on the mouth of motor, and spool is used to place reel.Coil paper unit II 3 also comprises spool and motor, and spool is connected on the mouth of motor, and spool is used to place reel.Winding unit I 4 and winding unit II 5 have comprised spool and motor equally, and spool is connected on the mouth of motor, and spool is used to place reel.These motors all are connected with controller 6, the control of controlled device 6.The bottom of coil paper unit I 2 is provided with a tension pick-up 7, this tension pick-up 7 is provided with movable tension rail, tension rail is connected on the potential device, and potential device is connected with controller 6, when tension rail when pulled potential device just the tension rail displacement can be fed back to controller 6.The tension force of the different sizes of the different just expressions in tension rail position in feedback procedure, the value of feedback of potential device will be different.Bottom at coil paper unit II 3 is provided with same tension pick-up 7.Ultrasonic transduter 8 also is installed on support 1, and this ultrasonic transduter 8 is connected with controller 6.Ultrasonic transduter 8 is between winding unit I 4, winding unit II 5.The detection direction of ultrasonic transduter 8 is towards support 1 bottom.Support 1 is also installed inhibiting device 9 between winding unit I 4, winding unit II 5, this inhibiting device 9 comprises two limited posts that vertically are fixed on the support 1, forms a rectangle limited mouth between two limited posts.Coil paper unit I 2, coil paper unit II 3, winding unit I 4, winding unit II 5, limited mouth, tension pick-up 7 and ultrasonic transduter 8 all are on the same vertical driving surface.
During work, on the spool of winding unit I 4, put into surface mount elements winding to be rolled up, on the spool of winding unit II5, put into empty reel.Put into empty reel on the spool of coil paper unit I 2, this reel is used to collect the coil paper in the surface mount elements winding from the winding unit I 4; Put into the coil paper of coiling on the spool of coil paper unit II 3, this coil paper is used to cover surface mount elements, plays the protector piece element.Winding unit I 4 rotates the winding of output surface mount elements, and this winding is entangled on the blank coil dish of coil paper unit II 3 by limited mouth.The coil paper of coil paper unit II 3 is exported in the reel on the winding unit II 5, covers on the surface mount elements.At this moment, based on the velocity of rotation on the winding unit II 5, all the other reel rotating speeds are followed this velocity of rotation.The speed of coil paper unit I 2, coil paper unit II 3 realizes following according to the detection data of each tension pick-up 7.Ultrasonic transduter 8 detects the height of surface mount elements winding, distance between winding and ultrasonic transduter 8 hour, the winding degree of tension is bigger, and winding this moment unit I 4 strengthens rotating speed so that discharge more winding, and the accent between winding and the ultrasonic transduter 8 is big; When the distance between winding and the ultrasonic transduter 8 was excessive, the winding degree of tension was too small, and winding is too loose, and winding this moment unit I 4 reduces rotating speed so that slowly discharge winding, with turning down between winding and the ultrasonic transduter 8.
Also can on the spool of winding unit II 5, put into surface mount elements winding to be rolled up during use, on the spool of winding unit I 4, put into empty reel; Put into empty reel on the spool of coil paper unit II 3, put into the coil paper of coiling on the spool of coil paper unit I 2, use by this way, use is identical with said process.
