Description

Technical Field

[0001] This utility model belongs to the field of winding machine technology, specifically an automatic winding machine self-stopping guide structure for wire breakage. Background Technology

[0002] A fully automatic winding machine is a machine that winds thread-like objects onto a specific workpiece. It uses a programmable controller as the control core of the equipment, and works with a robotic arm, pneumatic control components and actuators to complete functions such as automatic wire laying, automatic winding, automatic wire cutting, and automatic loading and unloading of the bobbin.

[0003] Meanwhile, a missing or broken wire detection mechanism for a winding machine, with announcement number CN216711232U, is disclosed. The mechanism includes a main body, with an inlet hole and an outlet hole on one side of the main body, respectively. An inlet drum and an outlet drum are fixedly connected to one side of the main body, respectively. Inside the main body are a first limiting wheel, a second limiting wheel, and an electromagnetic wire. A fixed frame is fixedly connected to the bottom inner wall of the main body. A rotating rod is rotatably connected to the top of the fixed frame. A contact wheel is rotatably connected to the top of the rotating rod. The electromagnetic wire contacts the bottom of the first limiting wheel, the bottom of the second limiting wheel, and the top of the contact wheel, respectively. A second contact point and a first contact point are fixedly connected to the bottom middle of the rotating rod and the bottom inner wall of the main body, respectively. Although the above-mentioned winding machine's missing or broken wire detection mechanism is equipped with a detection device during use, it lacks a broken wire clamping mechanism. After the winding machine stops, the wire is easily pulled back by the tension of the wire spool and leaves the wire hole, making subsequent wiring or wire replacement processes complicated and reducing production efficiency. Furthermore, the tension of the wire cannot be adjusted during use, affecting the winding of the wire.

[0004] Therefore, an automatic winding machine self-stop guiding structure is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an automatic winding machine self-stop guiding structure for wire breakage. It features real-time monitoring and adjustment of wire tension through a tension detection and guiding component, rapid machine stop and wire clamping upon wire breakage, and anti-displacement component to prevent accidental rotation of the rotating handle, thus ensuring the accuracy of tension detection and guidance. Overall, it improves the stability and convenience of winding operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding machine self-stop guiding structure for wire breakage, including a fixed bracket, with an infeed wheel and an outfeed wheel connected to both ends of the fixed bracket, a connecting frame located in the middle of the fixed bracket, a lead screw located on the rear side of the connecting frame, a rotating handle connected to one end of the lead screw, a lifting block connected to the lead screw, and a tension detection guiding assembly connected to the front end of the lifting block passing through the connecting frame. The tension detection guiding assembly includes a limit frame, a fixed frame, a guide wheel, a tension sensor, an electric push rod, and a clamping block. An anti-displacement assembly is located at the top of the connecting frame, and the anti-displacement assembly includes a positioning frame, a clamping plate, a guide rod, and a return spring.

[0007] Preferably, the infeed wheel and the outfeed wheel are at the same height, and their two ends are rotatably connected to a fixed bracket via bearings.

[0008] Preferably, the connecting frame has a guide groove that matches the lifting block, and the lifting block passes through the guide groove and connects to the fixing frame of the tension detection guide assembly.

[0009] Preferably, the limiting frame is symmetrically arranged on both sides of the fixed frame, the tension sensor is arranged on the fixed frame, the guide wheel is mounted on the force shaft of the sensor through a bearing, the electric push rod is symmetrically arranged on both sides of the limiting frame, and one end of the electric push rod is connected to the clamping block.

[0010] Preferably, the clamping block matches the shape of the groove of the guide wheel, and the clamping block is disposed below the groove of the guide wheel.

[0011] Preferably, the guide rod is slidably connected to the positioning frame, one end of the guide rod is connected to the clamping plate, the return spring is sleeved on the outside of the guide rod, and the return spring is disposed between the clamping plate and the positioning frame.

[0012] Preferably, the clamps are symmetrically arranged on both sides of the rotating handle, and the opposite side of the clamps is provided with a clamping groove that matches the outer wall of the rotating handle.

[0013] Preferably, sliding rods are provided at the four corners of the bottom of the positioning frame, and through holes matching the sliding rods are provided on the connecting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a tension detection guide assembly to directly connect the guide wheel and the tension sensor. When the wire passes through the guide wheel, the tension of the wire can be monitored in real time. At the same time, by rotating the handle, the lead screw is driven to rotate, so that the lifting block drives the tension detection guide assembly to rise and fall, and the height can be flexibly adjusted to regulate the tension.

[0015] 2. With the electric push rod and the clamping block, the tension sensor can quickly detect the tension change at the moment of wire breakage and transmit the signal to the control system in a timely manner. The control system responds quickly and can control the winding machine to stop operating in a very short time. At the same time, the electric push rod drives the clamping block to clamp the wire in the groove of the guide wheel to prevent the broken wire from tangling and knotting, which facilitates subsequent wiring.

[0016] 3. This utility model, through the anti-displacement component, clamps the rotating handle under the action of the return spring via the clamping plate, effectively preventing accidental rotation of the rotating handle due to equipment vibration, operator mis-touch, etc., ensuring that the height of the tension detection guide component, which has been adjusted during the winding process, will not change, thus guaranteeing the continuous accuracy of the tension detection and guiding functions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following describes an embodiment of this utility model based on its overall structure.

[0021] like Figures 1 to 5As shown, this utility model provides an automatic winding machine self-stop guiding structure for wire breakage, including a fixed bracket 1. The two ends of the fixed bracket 1 are respectively connected to an inlet wheel 2 and an outlet wheel 3, which guide the wire in and out. A connecting frame 4 is provided in the middle of the fixed bracket 1. A lead screw 5 is provided on the rear side of the connecting frame 4. One end of the lead screw 5 is connected to a rotating handle 6. A lifting block 7 is connected to the lead screw 5. The front end of the lifting block 7 passes through the connecting frame 4 and is connected to a tension detection guiding assembly 8. The tension detection guiding assembly 8 includes a limit frame 81, a fixed frame 82, a guide wheel 83, a tension sensor 84, an electric push rod 85, and a clamping block 86. An anti-displacement assembly 9 is provided on the top of the connecting frame 4. The anti-displacement assembly 9 includes a positioning frame 91, a clamping plate 92, a guide rod 93, and a return spring 94. The anti-displacement assembly 9 is used to fix the rotating handle 6.

[0022] In this embodiment, the infeed wheel 2 and the outfeed wheel 3 are at the same height. The two ends of the infeed wheel 2 and the outfeed wheel 3 are rotatably connected to the fixed bracket 1 by bearings. The wire passes above the infeed wheel 2 and the outfeed wheel 3 and passes under the guide wheel 83.

[0023] The connecting frame 4 has a guide groove that matches the lifting block 7. The lifting block 7 passes through the guide groove and is connected to the fixing frame 82 of the tension detection guide assembly 8. When the lead screw 5 rotates, the lifting block 7 will drive the tension detection guide assembly 8 to move up and down stably under the limiting action of the guide groove, so as to avoid deviation.

[0024] Limiting frames 81 are symmetrically arranged on both sides of fixed frame 82. Tension sensor 84 is mounted on fixed frame 82. Guide wheel 83 is mounted on the force shaft of sensor through bearing. Electric push rod 85 is symmetrically arranged on both sides of limiting frame 81. One end of electric push rod 85 is connected to top block 86. The installation of tension sensor 84 must ensure that its force shaft is coaxial with the wheel axle of guide wheel 83. It is fixed to the preset installation position of fixed frame 82 with bolts to ensure that the tension generated when guide wheel 83 rotates can be accurately transmitted to sensor.

[0025] The clamping block 86 matches the shape of the wire groove of the guide wheel 83. The clamping block 86 is set below the wire groove of the guide wheel 83. At the moment of wire breakage, the clamping block 86 is driven by the electric push rod 85 to clamp the wire in the wire groove of the guide wheel 83 to prevent the broken wire from tangling and knotting.

[0026] The guide rod 93 is slidably connected to the positioning frame 91. One end of the guide rod 93 is connected to the clamping plate 92. The return spring 94 is sleeved on the outside of the guide rod 93 and is located between the clamping plate 92 and the positioning frame 91. The clamping plate 92 is symmetrically arranged on both sides of the rotating handle 6. The opposite side of the clamping plate 92 is provided with a clamping groove that matches the outer wall of the rotating handle 6. After the height of the tension detection guide assembly 8 is adjusted, the clamping plate 92 is slid, which causes the guide rod 93 to slide. At the same time, the return spring 94 is compressed. The rebound force of the return spring 94 makes the clamping plate clamp the rotating handle 6, which effectively prevents the rotating handle 6 from rotating accidentally due to equipment vibration, operator accidental contact, etc.

[0027] Sliding rods are provided at the four corners of the bottom of the positioning frame 91. Through holes matching the sliding rods are provided on the connecting frame 4. When the rotating handle 6 needs to be used, the clamping plate 92 can be separated from the rotating handle 6, and the height of the positioning frame 91 can be adjusted by the sliding rods to facilitate the rotation of the rotating handle 6.

[0028] The tension sensor and electric actuator are existing technologies and will not be described in detail. Additionally, this invention includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0029] The working principle and process of the automatic winding machine's self-stop guide structure after wire breakage: After the wire is drawn out from the unwinding device, it first contacts the infeed wheel 2. Since the infeed wheel 2 and the outlet wheel 3 are at the same height, they can provide stable initial guidance for the wire, reducing friction and jamming when the wire enters the device. Through the tension detection guide component, when the wire passes between the infeed wheel 2 and the outlet wheel 3, the rotating handle drives the lead screw to rotate, causing the lifting block to lift the tension detection guide component. When the guide wheel 83 contacts the wire, the tension of the wire is monitored in real time by the tension sensor. At the same time, the tension between the guide wheel 83 and the wire can be adjusted by the up and down movement of the guide wheel 83. When adjusting the tension, the extension and retraction of the electric push rod 85 can be controlled to drive the clamping block 86 to perform auxiliary clamping or loosening operations on the wire on the guide wheel 83. After the height adjustment is completed, the clamping plate 92 clamps the rotating handle 6 under the action of the return spring 94, effectively preventing the rotating handle 6 from rotating accidentally due to equipment vibration, operator accidental contact, etc., ensuring that the height of the tension detection guide component 8, which has been adjusted during the winding process, will not change, thus ensuring the continuous accuracy of the tension detection and guiding functions. When the wire is wound normally, the tension sensor 84 continuously monitors a stable tension signal and transmits the signal to the connected control system. At the moment of wire breakage, the tension sensor can quickly sense the tension change and transmit the signal to the control system in a timely manner. The control system responds quickly and can control the winding machine to stop operating in a very short time. At the same time, it controls the electric push rod to drive the clamping block to clamp the wire in the groove of the guide wheel, preventing the broken wire from tangling and knotting, which facilitates subsequent wiring.
