Figure 2 This is the front view of the strip material winding device. Figure 3 It is a top view of the strip material winding device. Figure 4 It is a side view of the strip material winding device. Figure 5 This is a schematic diagram of the cooperation between the strip material winding device and the working machine, refer to Figure 1-Figure 5 , the strip material winding device comprises:

[0031] The motor M, illustratively, in the embodiment of the present utility model, the motor M may be a DC motor.

[0032] The winding reel 110, the rotating shaft of the motor M passes through the center of the winding reel 110, and is fixedly connected to the winding reel 110. Exemplarily, the winding reel 110 generally includes a shaft tube and two discs, the two discs are respectively arranged at both ends of the shaft tube, and are arranged concentrically with the shaft tube. The center of the shaft tube is provided with a shaft hole, and the rotating shaft of the motor M passes through the shaft hole and is locked by a fixing pin or other locking mechanism, which is not limited in the embodiment of the utility model. When winding the material, one end of the strip material is connected to the shaft tube of the winding reel 110, and the motor M drives the winding reel 110 to wind the strip material onto the shaft tube.

[0033] The detection rod 120 is fixed on a fulcrum O to form a lever. The distance from the first end A of the detection rod 120 to the fulcrum O is greater than the distance from the second end B of the detection rod 120 to the fulcrum O. The first end A of the detection rod 120 is provided with a guide rod 121 perpendicular to the detection rod 120. The guide rod 121 guides the movement of the strip material. The guide rod 121 acts on the strip material by its own weight. The strip material is connected to the feed port of the take-up reel 110, that is, the strip material is discharged from the discharge port of the strip material and connected to the shaft tube of the take-up reel 110.

[0034] The control circuit includes a first switch SW1 and a second switch SW2. The first switch SW1 is located above the second switch SW2, and the second end B of the detection rod 120 is located between the first switch SW1 and the second switch SW2. When the first end A of the detection rod 120 descends due to its own weight and the second end B of the detection rod 120 rises and is triggered to close, the motor M starts to drive the material reel 110 to rotate and reel in; when the second switch SW2 is disconnected when the first end A of the detection rod 120 rises due to the tension of the strip material and the second end B of the detection rod 120 descends and is triggered to close, the motor M stops rotating.

[0035] For example, in the initial state, the first switch SW1 is in the open state, and the second switch SW2 is in the closed state. The first end A of the detection rod 120 drops due to its own weight, driving the strip material to be discharged from the discharge port of the working machine. The first end A of the detection rod 120 gradually drops, and the second end B of the detection rod 120 gradually rises. When the second end B of the detection rod 120 touches the first switch SW1, the first switch SW1 is closed, the circuit where the motor M is located is turned on, and the motor M starts, driving the material reel 110 to rotate and reel in the strip material. As the strip material is reeled in, the strip material is gradually tightened, so that the first end A of the detection rod 120 is gradually lifted, and the second end B of the detection rod 120 is gradually lowered. The first switch SW1 is disconnected, but during this period, the motor M is powered on by maintaining the circuit. When the second end B of the detection rod 120 touches the second switch SW2, the second switch SW2 is disconnected, cutting off the power circuit of the motor M, and the motor M stops rotating. The first end A of the detection rod 120 descends due to its own weight, driving the strip material to be discharged from the discharge port of the working machine, and repeating the above process, so that the strip material is automatically rolled up.

[0036] The strip material winding device provided by the embodiment of the utility model comprises a motor, a winding reel, a detection rod and a control circuit, the rotating shaft of the motor passes through the center of the winding reel and is fixedly connected to the winding reel, the detection rod is fixed on a fulcrum to form a lever, the distance from the first end of the detection rod to the fulcrum is greater than the distance from the second end of the detection rod to the fulcrum, the first end of the detection rod is provided with a guide rod perpendicular to the detection rod, the guide rod acts on the strip material by its own weight, the strip material is connected to the feeding port of the winding reel, the control circuit comprises a first switch and a second switch, the first switch is located above the second switch, the second end of the detection rod is located between the first switch and the second switch, when the first end of the detection rod descends due to its own weight and the second end of the detection rod rises and is triggered to close, the motor starts, drives the winding reel to rotate and rewind the material, and when the second switch is disconnected when the first end of the detection rod rises due to the tensioning of the strip material and the second end of the detection rod descends and is triggered, the motor stops rotating. The utility model ingeniously utilizes the lever principle of the detection rod and combines it with a touch switch to complete the automatic reeling of the strip material, thereby avoiding machine failure caused by the blockage of the strip material and the potential safety hazard caused by the accumulation of the strip material, thereby improving the machine stability and on-site safety.

The first end A of the detection rod 120 drops due to its own weight, driving the strip material to be discharged from the discharge port of the working machine. The first end A of the detection rod 120 gradually drops, and the second end B of the detection rod 120 gradually rises. When the second end B of the detection rod 120 touches the first switch SW1, the first switch SW1 is closed, the coil KJ of the relay is energized, and the switch KA of the relay is attracted to complete the self-locking. The circuit where the motor M is located is turned on, and the motor M starts, driving the material reel 110 to rotate and reel in the strip material. As the strip material is reeled in, the strip material is gradually tightened, so that the first end A of the detection rod 120 is gradually lifted, and the second end B of the detection rod 120 is gradually lowered, and the first switch SW1 is disconnected. Since the switch KA of the relay is still closed, the motor M is still powered on, and the material reel 110 continues to rotate to reel in the strip material. When the second end B of the detection rod 120 touches the second switch SW2, the second switch SW2 is disconnected, cutting off the power circuit of the motor M, and the motor M stops rotating. At the same time, the coil KJ of the relay loses power, and the switch KA of the relay is disconnected. The first end A of the detection rod 120 drops due to its own weight, and the second end B rises. The second switch SW2 is closed again, and the next material collection cycle begins.

[0048] For example, in a specific embodiment of the present invention, taking the receipt of chip tape as an example, the chips are usually delivered to customers in the form of rolls of tape materials when leaving the factory. The tape is usually a long strip made of plastic or other materials, with a series of chip packages on it, and each chip package is arranged at a fixed distance.

[0049] After receiving the tape, the user needs to burn the chip in the tape and write the pre-written program code into the chip's memory. The burning process usually uses an automatic tape chip feeder and burning equipment to complete the feeding and burning. After the burning is completed, the chip is peeled off from the tape and transferred to the tray, and the tape of the peeled chip is continuously discharged from the tape outlet. The tape is tough. As the tape continues to accumulate, it often gets blocked and causes poor discharge, which in turn causes shutdowns or collisions. In addition, the tape is getting longer and longer, and is piled up messily on site, which may pose a risk of tripping workers.
