Detailed Description
Referring to fig. 1, the automatic winding and rewinding system for carrier tapes of the present invention comprises,

the receiving track 20 is used for being in butt joint with the previous process equipment and receiving a carrier tape to be received from a carrier tape discharging end of the previous process equipment;
the feeding device 30 is used for conveying the carrier tape received by the receiving track to the winding device;
the winding device 40 is used for winding the carrier tape from the feeding device onto an empty material tray, and comprises a winding servo motor for driving the material tray to rotate so as to wind the carrier tape onto the material tray;
the upper and lower disc device is used for conveying the material disc above the disc storage device 10 to the winding device 40 and conveying the full material disc after the winding device 40 is wound to the disc storage device 10;
the material receiving track 20 and the winding device 40 are respectively arranged at the feeding end side and the discharging end side of the feeding device 30, and the disc storage device 10 is arranged at the front side of the winding device 40;
the device also comprises a tension control device, wherein the tension control device controls the continuous carrier tape received by the material receiving track 20 from the carrier tape discharging end of the previous process equipment to be wound on the material tray 70 by the winding device with constant tension;
In this embodiment, the former process equipment is disposed on the right side of the system of the present invention, so in this embodiment, the carrier tapes are all transported from right to left, wherein the mentioned discharge ends are all at the left end of the component, and the feed ends are all at the right end of the component.
The tension control device comprises a carrier tape tail end sensor 63, a tension wheel mechanism 61 and a compression bar mechanism 62, wherein the carrier tape tail end sensor 63 is arranged at the feeding end part of the receiving track 20, the tension wheel mechanism 61 is arranged between the receiving track 20 and the feeding device 30, and the compression bar mechanism 62 is arranged on the winding device 40; when the length of the carrier tape conveyed by the previous process equipment reaches the preset coiling length of the carrier tape of the material tray, the conveyed carrier tape is cut off by the previous process equipment to form the tail end of the carrier tape, the tension of the carrier tape is controlled to be constant by the tension wheel mechanism 61 before the tail end of the carrier tape is sensed by the tail end sensor 63, and the tension of the carrier tape is controlled to be constant by the pressure bar mechanism 62 after the tail end of the carrier tape is sensed by the tail end sensor 63.
Referring to fig. 3 to 5, the tension pulley mechanism 61 includes a floating plate 614, a tension bracket 613, a tension pulley 611 and a bearing rail 612, the tension bracket 613 is fixedly arranged between the receiving rail 20 and the feeding device 30, the bearing rail 612 is fixedly mounted on the floating plate 614, the tension pulley 611 is rotatably mounted on the floating plate 614 and is positioned above the bearing rail 612, a floating sliding rail 615 extending vertically is fixedly mounted on the front side surface of the tension bracket 613, and the floating plate 614 is slidably connected with the floating sliding rail 615 through a sliding block 6111; the carrier tape from the receiving track 20 passes through the tension pulley 611 and the bearing track 612 and then enters the feeding device 30, and the tension pulley 611 can be in rolling contact with the carrier tape, so that the front carrier tape can be tensioned under the self-weight downward pressing action of the tension pulley 611 all the time when the tail end sensor 63 of the carrier tape senses the tail end of the carrier tape; in the process that the carrier tape is continuously conveyed to the feeding device from the former process equipment through the material receiving track 20, the carrier tape is U-shaped and sags under the action of the dead weight of the tension wheel 611 of the tension wheel mechanism 61 so as to be tensioned by the tension wheel 611, and therefore, the tension wheel mechanism can also play an effective carrier tape storage function, so that when the carrier tape discharging speed of the former process equipment is far greater than the carrier tape winding speed of the winding device 40 or the disc changing speed of a material disc, the carrier tape received by the material receiving track 20 from the discharging end of the former process equipment can be temporarily stored by the tension wheel mechanism 61, and the former process equipment can always keep the discharging of the carrier tape without stopping, thereby ensuring the continuous working efficiency of the whole production line. Because the length of the whole receiving track 20 and the feeding length of the feeding device 30 are constant all the time, and in order to prevent the carrier belt from being broken in the rolling process, the rolling speed of the carrier belt by the rolling device 40 is usually smaller than the discharging speed of the carrier belt on the previous process equipment, and then the whole carrier belt is in a relatively loose state in the rolling process, a certain weight of the tension wheel 611 arranged between the receiving track 20 and the feeding device 30 can fall under the action of dead weight so as to tension the carrier belt to ensure the constant tension of the carrier belt; in practical production applications, the tension wheels 611 with different weights are adopted or weights with different weights are hung on the tension wheels 611 to realize the adjustment of constant tension.
The tension bracket 613 is provided with three sensors from top to bottom, namely a material returning position sensor 616a, an upper limit position sensor 616b and a lower limit position sensor 616c, and the three sensors 616a, 616b and 616c are respectively and electrically connected with a rolling servo motor 413 of the winding device; when the floating plate 614 drives the tension wheel 611 and the bearing rail 612 to move up to the position of the material returning position sensor 616a, the material returning position sensor 616a controls the winding servo motor 413 to rotate reversely, so that the material returning process of the winding carrier tape is realized; when the floating plate 614 drives the tension wheel 611 and the bearing rail 612 to move upwards to the position of the upper limit position sensor 616b, the upper limit position sensor 616b controls the rolling servo motor 413 to reduce the speed, so that the risk of the carrier tape being broken due to the too high winding speed of the carrier tape of the winding device is avoided; when the floating plate 614 drives the tension pulley 611 and the bearing rail 612 to move downward to the position of the lower limit position sensor 616c, the lower limit position sensor 616c controls the winding servo motor 413 to rotate in an accelerating manner, so that the influence on the normal operation of the previous process equipment due to excessive storage of the tension pulley mechanism 61 is avoided.
