Description

Technical Field

[0001] This utility model relates to the field of electronic wire feeding technology, specifically an electronic wire feeding mechanism with a missing wire alarm function. Background Technology

[0002] In traditional electronic wire feeding processes, due to the lack of an effective wire shortage detection mechanism, workers typically need to manually monitor the remaining amount and feeding status of electronic wires through inspections. However, manual inspections rely on the worker's sense of responsibility and attention, and are prone to failure to detect wire shortages due to fatigue or negligence. When electronic wires are exhausted or the feeding process is interrupted, subsequent processing stations will be forced to stop due to lack of raw material supply, resulting not only in decreased production efficiency but also potentially in energy waste and unnecessary wear and tear on components due to equipment idling. Therefore, those skilled in the art have provided an electronic wire feeding mechanism with a wire shortage alarm function to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide an electronic wire feeding mechanism with a missing wire alarm function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electronic wire feeding mechanism with a missing wire alarm function includes an upper support plate and a lower support plate. The lower support plate is provided on the upper support plate. A fixing plate is fixedly connected to the surface of the upper support plate. A pressure sensor and a positioning rod are fixedly connected inside the fixing plate. A transmission block is slidably connected to the fixing plate. One end of the transmission block abuts against the pressure sensor. A counterweight rod is rotatably connected to the upper support plate. The lower surface of the counterweight rod abuts against the transmission block.

[0006] Furthermore, a positioning rod is fixedly connected to the surface of the pressure sensor, and a return spring is provided on the surface of the positioning rod, with one end of the return spring abutting against the transmission block.

[0007] Furthermore, the pressure sensor is electrically connected to the control motherboard, and a support plate is fixedly connected to the lower surface of the counterweight rod.

[0008] Furthermore, the upper and lower support plates are provided with adjustment components, which include a limiting rod and a threaded rod. The limiting rod and the threaded rod are fixedly connected to the lower surface of the upper support plate, and both the limiting rod and the threaded rod are placed inside the lower support plate.

[0009] Furthermore, the adjustment assembly also includes a threaded sleeve, a limiting plate, and a limiting block. The limiting block is fixedly connected inside the lower receiving plate, and the limiting plate is rotatably connected to the limiting block. The threaded rod surface is threadedly connected to the threaded sleeve, and the limiting plate is fixedly connected to the surface of the threaded sleeve.

[0010] Furthermore, the adjustment assembly also includes a transmission bevel gear, an adjustment bevel gear, and an adjustment rod. The transmission bevel gear is fixedly connected to the surface of the threaded sleeve, and the adjustment rod is rotatably connected to the lower support plate. One end of the adjustment rod is fixedly connected to the adjustment bevel gear, and the adjustment bevel gear meshes with the transmission bevel gear.

[0011] By adopting the above technical solution

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By integrating a pressure sensor, a transmission block, and a counterweight rod onto the fixed plate of the upper receiving plate, a missing wire detection mechanism based on "gravity-pressure transmission" is constructed. When the electronic wire is being fed normally, the electronic wire generates a supporting force on the counterweight rod, preventing the counterweight rod from fully pressing down on the transmission block, and the pressure on the pressure sensor remains within the set threshold. When a missing wire occurs, the supporting force of the electronic wire disappears, and the counterweight rod presses down against the transmission block under its own weight. The transmission block is then pressed against the pressure sensor, causing the pressure sensor to send an electrical signal to the control board, ultimately triggering an alarm. This mechanism directly achieves detection through the synergistic effect of mechanical structure and electronic components, without the need for complex optical or electromagnetic induction devices. It has high detection accuracy and fast response speed, and can immediately remind workers to replenish the electronic wire, avoiding downtime in subsequent processing steps due to missing wires and ensuring the continuous and stable operation of the entire feeding process.

[0014] 2. By rotating the adjusting rod, the adjusting bevel gear can be rotated, and the adjusting bevel gear meshes with the transmission bevel gear on the surface of the transmission block, thereby driving the threaded sleeve to rotate on the threaded rod. Since the limiting plate inside the limiting block is fixedly connected to the surface of the threaded sleeve, the limiting plate can limit the offset of the threaded sleeve when it rotates with the threaded rod, so that when the threaded sleeve rotates along the threaded rod, it ultimately pushes the upper support plate to move up and down synchronously with the threaded rod, realizing the adjustment of the distance between the upper support plate and the lower support plate. This adjustment method does not require disassembly of the mechanism and can be completed through simple mechanical transmission, which is convenient and efficient. Attached Figure Description

[0020] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] Please see Figures 1-4 This utility model provides an embodiment of an electronic wire feeding mechanism with a missing wire alarm function, including an upper support plate 1 and a lower support plate 2. The lower support plate 2 is disposed on the upper support plate 1. A fixing plate 3 is fixedly connected to the surface of the upper support plate 1. A pressure sensor 8 and a positioning rod 9 are fixedly connected inside the fixing plate 3. A transmission block 11 is slidably connected to the fixing plate 3. One end of the transmission block 11 abuts against the pressure sensor 8. A counterweight rod 4 is rotatably connected to the upper support plate 1. The lower surface of the counterweight rod 4 abuts against the transmission block 11. The upper support plate 1 and the fixing plate 3 are made of metal material that meets the size requirements. The fixing plate 3 is vertically fixed to the preset installation position on the upper surface of the upper support plate 1 by bolt connection.

[0022] In this embodiment, a positioning rod 9 is fixedly connected to the surface of the pressure sensor 8, and a return spring 7 is provided on the surface of the positioning rod 9. One end of the return spring 7 abuts against the transmission block 11. The pressure sensor 8 is electrically connected to the control main board 10, and a support plate 5 is fixedly connected to the lower surface of the counterweight rod 4. Mounting holes adapted to the pressure sensor 8 and positioning rod 9 are opened inside the fixed plate 3. The pressure sensor 8 is first embedded into the mounting hole, and an electrical signal connection is established between the pressure sensor 8 and the external control main board 10 through a wire. The input end face of the pressure sensor 8 is inclined. The transmission block 11 is slidably installed in the groove of the fixed plate 3, and the side of the transmission block 11 closest to the pressure sensor 8 is correspondingly inclined, so that one end of the transmission block 11 naturally abuts against the sensing surface of the pressure sensor 8, and the other end extends to the outside of the fixed plate 3. A reset spring 7 is fitted onto the surface of the positioning rod 9. The spring compression is adjusted so that one end of the reset spring 7 is tightly pressed against the transmission block 11, and the other end is fixed to the limiting protrusion of the fixing plate 3. This ensures that the transmission block 11 can maintain its initial position under the support of the reset spring 7 when no external force is applied, without compressing the pressure sensor 8. A metal support plate 5 is welded or bolted to the lower surface of the counterweight rod 4. The counterweight rod 4 is then rotatably connected to the bracket of the upper support plate 1 via a rotating shaft. The position of the rotating shaft is adjusted so that when the counterweight rod 4 hangs down naturally, the support plate 5 can accurately press on the end of the transmission block 11 that extends to the outside of the fixing plate 3. At this time, the reset spring 7 is in a slightly compressed state, and the pressure on the pressure sensor 8 is lower than the alarm threshold. The metal support plate 5 can effectively reduce the friction between the sensor and the electronic wire and increase the wear resistance.

[0023] In this embodiment, the upper support plate 1 and the lower support plate 2 are provided with an adjustment assembly. The adjustment assembly includes a limiting rod 6 and a threaded rod 12. The limiting rod 6 and the threaded rod 12 are fixedly connected to the lower surface of the upper support plate 1, and both the limiting rod 6 and the threaded rod 12 are located inside the lower support plate 2. The adjustment assembly also includes a threaded sleeve 13, a limiting plate 14, and a limiting block 15. The limiting block 15 is fixedly connected inside the lower support plate 2, and the limiting plate 14 is rotatably connected to the limiting block 15. The threaded sleeve 13 is threadedly connected to the surface of the threaded rod 12, and the limiting plate 14 is fixedly connected to the threaded rod 12. The adjusting assembly includes a transmission bevel gear 16, an adjusting bevel gear 17, and an adjusting rod 18, all fixedly connected to the surface of the threaded sleeve 13. The lower receiving plate 2 is rotatably connected to the adjusting rod 18, with one end of the adjusting rod 18 fixedly connected to the adjusting bevel gear 17, which meshes with the transmission bevel gear 16. Mounting holes are provided on the upper surface of the lower receiving plate 2, and the limiting rod 6 and the threaded rod 12 are vertically fixed to corresponding positions on the lower surface of the upper receiving plate 1. Then, the upper receiving plate 1... The limiting rod 6 and the threaded rod 12 are inserted into the mounting holes of the lower receiving plate 2, so that the upper receiving plate 1 is initially erected above the lower receiving plate 2. The threaded sleeve 13 is fitted onto the surface of the threaded rod 12. A limiting plate 14 that matches the threaded sleeve 13 is selected and fixed to the outer wall of the threaded sleeve 13 by welding. At the same time, a limiting block 15 is installed inside the lower receiving plate 2. A sliding groove that matches the limiting plate 14 is opened on the limiting block 15. The limiting plate 14 is slidably embedded into the sliding groove of the limiting block 15 to ensure that the limiting plate 14 can restrict the rotation of the threaded sleeve 13. The threaded sleeve 13 rotates with the threaded rod 12, which in turn pushes the threaded rod 12 to move up and down. The lower end of the threaded sleeve 13 is welded with a transmission bevel gear 16 to ensure that the transmission bevel gear 16 and the threaded sleeve 13 are coaxial. Then, a mounting hole is opened on the side wall of the lower support plate 2, and the adjusting rod 18 is passed through the mounting hole. An adjusting bevel gear 17 is welded to the end of the adjusting rod 18 located inside the lower support plate 2 so that the adjusting bevel gear 17 and the transmission bevel gear 16 are precisely meshed. A knob is installed on the end of the adjusting rod 18 that extends outside the lower support plate 2 for easy operation by the staff.

[0024] Start the control motherboard 10 and enter the alarm threshold setting interface. Based on the weight of the counterweight rod 4 and the elasticity parameters of the return spring 7, set the alarm threshold of the pressure sensor 8 to a predetermined value. Place the electronic wire in the through groove between the upper support plate 1 and the lower support plate 2 according to the actual feeding path in production. At this time, the counterweight rod 4 cannot be fully pressed down under the supporting force of the electronic wire, and the transmission block 11 is only subjected to slight pressure from the return spring 7. The pressure value detected by the pressure sensor 8 is lower than the alarm threshold, and the normal feeding state is determined to be qualified. Remove the electronic wire supporting the counterweight rod 4 to simulate a missing wire scenario. At this time, the counterweight rod 4 is in self- Under the influence of gravity, the device rotates downwards, and the support plate 5 pushes the transmission block 11 to slide along the groove of the fixed plate 3, squeezing the pressure sensor 8. The pressure value detected by the pressure sensor 8 rises rapidly. After receiving the electrical signal, the control board 10 immediately triggers an audible and visual alarm. The staff can view the alarm position through the display screen of the control board 10 and determine that the missing wire alarm function is successfully debugged. In the alarm state, the electronic wire is placed under the counterweight rod 4 again, the electronic wire support force is restored, the counterweight rod 4 rotates upwards, and the transmission block 11 returns to its initial position under the elastic force of the reset spring 7. The alarm is automatically deactivated, and the reset function is determined to be normal.

[0025] By integrating a pressure sensor 8, a transmission block 11, and a counterweight rod 4 onto the fixing plate 3 of the upper receiving plate 1, a missing wire detection mechanism based on "gravity-pressure transmission" is constructed. When the electronic wire is being fed normally, the electronic wire generates a supporting force on the counterweight rod 4, preventing the counterweight rod 4 from fully pressing down on the transmission block 11, and the pressure on the pressure sensor 8 remains within a set threshold. However, when a missing wire occurs, the supporting force of the electronic wire disappears, and the counterweight rod 4, under its own weight, presses down against the transmission block 11. The transmission block 11, under pressure, squeezes the pressure sensor 8, causing the pressure sensor 8 to send an electrical signal to the control main board 10, ultimately triggering an alarm. This mechanism directly achieves detection through the synergistic effect of mechanical structure and electronic components, without the need for complex optical or electromagnetic induction devices. It boasts high detection accuracy, fast response speed, and can detect wires in the first... The system immediately alerts staff to replenish electronic wires to prevent subsequent processing steps from stopping due to wire shortages, ensuring the continuous and stable operation of the entire feeding process. By rotating the adjusting rod 18, the adjusting bevel gear 17 can be rotated, and the adjusting bevel gear 17 meshes with the transmission bevel gear 16 on the surface of the transmission block 11, thereby driving the threaded sleeve 13 to rotate on the threaded rod 12. Since the limiting plate 14 inside the limiting block 15 is fixedly connected to the surface of the threaded sleeve 13, the limiting plate 14 can limit the offset of the threaded sleeve 13 when it rotates with the threaded rod 12. When the threaded sleeve 13 rotates along the threaded rod 12, it ultimately pushes the upper support plate 1 to move up and down synchronously with the threaded rod 12, realizing the adjustment of the distance between the upper support plate 1 and the lower support plate 2. This adjustment method does not require disassembly of the mechanism and can be completed through simple mechanical transmission, which is convenient and efficient.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
