Description

Technical Field

[0001] This utility model relates to the field of wire feeding machines, specifically to an automatic wire feeding machine for copper and aluminum busbars. Background Technology

[0002] With the rapid development of the global new energy industry, copper busbars and aluminum busbars, as highly efficient conductive materials, are increasingly widely used in fields including but not limited to photovoltaics, wind power, energy storage systems, and new energy vehicles. In the application of new energy vehicles, copper busbars serve as the core conductive components of power battery modules, while aluminum busbars are used in the power transmission systems of lightweight vehicle bodies.

[0003] In the current new energy manufacturing field, copper busbars and aluminum busbars are generally in the form of coiled materials. They are fed and transported by an automatic wire feeding machine, so that the coiled copper or aluminum busbars can enter the bending and other processing steps. The existing wire feeding machine mainly includes the following structure: wire feeding frame, guiding device and drive system for conveying and feeding copper or aluminum busbars.

[0004] However, although existing technologies have initially achieved automated wire laying, the following key issues still exist: existing equipment mostly relies on manual labor with the help of lifting tools to load and position copper or aluminum busbar coils, making it difficult to conveniently load and unload copper or aluminum busbar coils. This process also increases labor intensity and safety hazards, thus affecting the performance and production efficiency. Furthermore, the existing conveying and guiding settings for copper or aluminum busbars are relatively simple, reducing the accuracy of wire laying and thus affecting the conveying effect and stability, which is not conducive to the use of the wire laying machine. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide an automatic copper and aluminum busbar feeding machine, so as to solve the technical problems in the prior art of the copper and aluminum busbar feeding machine that are not easy to load and unload the coils, and have poor conveying accuracy and stability of copper and aluminum busbars, thus affecting the production efficiency and use of the feeding machine.

[0006] The objective of this utility model is achieved through the following means:

[0007] An automatic copper and aluminum busbar unwinding machine includes a frame. One end of the frame is connected to a material rack via a column. The material rack has an opening for placing material rolls. A top shaft and a tail top are connected to the inner side of the opening. An unwinding drive is connected to the side of the material rack for driving the top shaft to rotate. The tail top is telescopically and slidably mounted on the material rack and can move closer to or away from the top shaft. The bottom of the material rack is hinged to the column via a support end. A lifting drive is provided on the frame. The telescopic end of the lifting drive is hinged to one end of the material rack. The lifting drive can drive the material rack to perform lever movement along the support end as a fulcrum by telescoping. One end of the material rack is provided with a support frame. A rotating device for transmission and conveying is connected to the support frame via a guide mechanism. The guide mechanism includes a first moving component and a second moving component. The first moving component extends parallel to the axial direction of the top shaft. The second moving component is mounted on the first moving component. The rotating device is mounted on the second moving component and can move closer to or away from the opening along the second moving component. A slider-type electronic ruler is connected to the rotating device on the second moving component.

[0008] Furthermore, as described above, the column is provided with a connecting bracket for pairing and connecting the support end. The material rack is paired with the connecting bracket through the support end and hinged through the first hinge shaft.

[0009] The material rack and the column are hinged by the first hinge shaft. The support end is connected to the connecting bracket to form a fulcrum for supporting the material rack. With the lifting drive, the material rack can be tilted up or down to realize the lifting action of the material rack. This makes it suitable for convenient lifting and loading of roll materials and improves the convenience of use.

[0010] Furthermore, as described above, the frame is provided with a support column, and a connector for mounting a lifting drive is connected to the support column. The lifting drive is mounted on the connector and includes a screw jack and a lifting drive motor for driving the screw jack to extend and retract. The screw jack is mounted on the connector, and the extension end of the screw jack extends toward the material rack and is connected to a spherical bearing. The output end of the lifting drive motor is connected to the input end of the screw jack.

[0011] The lifting drive motor can drive the screw of the screw jack to extend and retract, thereby adjusting the height of the material rack for easy loading or unloading.

[0012] Furthermore, as described above, the material rack is provided with a connecting end relative to the opening end, and the connecting end is hinged to the spherical bearing via a second hinge shaft.

[0013] The screw jack is hinged to the connecting end via a spherical bearing, so that when the screw of the screw jack extends, one end of the material rack connecting the top shaft and the tail top is pressed down, which allows for convenient loading and feeding. After loading, the screw jack resets, causing the material rack to lift up and allow for subsequent unloading and conveying.

[0014] Furthermore, as described above, the end of the frame near the material rack is provided with a feeding end, which is connected to a slidable material support plate via a slide groove. The material support plate can move along the slide groove and between the top shaft and the tail shaft via rollers.

[0015] The coiled copper or aluminum busbars are placed on the support plate. When one end of the material rack connecting the top shaft and the tail shaft is pressed down, the support plate drives the coil and can move along the distance between the top shaft and the tail shaft via rollers, which facilitates clamping and feeding, further improving the convenience of feeding.

[0016] Further as described above, the second moving component includes a guide shaft, a bearing seat connected to the guide shaft, and two sliding seats. The guide shaft is installed between the two sliding seats. The sliding seats are connected to the first moving component and can move along the first set of moving components. A spring is sleeved on the guide shaft and is disposed between the sliding seats and the bearing seat.

[0017] Furthermore, as described above, the first movable group includes two sets of optical axes arranged opposite to each other, and the two sets of optical axes are mounted on the support frame via support seats.

[0018] Furthermore, as described above, a mounting plate for mounting a slider-type electronic ruler is connected between the two sliding seats, and the slider-type electronic ruler is connected to the bearing seat via a connecting rod.

[0019] Furthermore, as described above, the rotating device includes two opposing clamping plates and a plurality of rollers disposed between the two clamping plates. The sides of the clamping plates are connected to bearing seats, allowing the clamping plates to move axially along the guide shaft via the bearing seats. The clamping plates have inlet and outlet ports, and vertically arranged guide shafts are connected to the inlet and outlet ports of the two clamping plates via mounting blocks.

[0020] Multiple rollers are used to guide and convey the material, and vertically arranged guide shafts at the inlet and outlet can guide and limit the material.

[0021] Furthermore, as described above, the frame is connected to a guide roller for material conveying via a vertical frame.

[0022] Furthermore, as described above, the top shaft and the tail shaft are installed inside the opening, and a locking handle is connected to the outwardly extending end of the tail shaft. The unwinding drive includes a reducer and an unwinding drive motor. The output end of the reducer is coaxially connected to the top shaft, and the output end of the unwinding drive motor is connected to the input end of the reducer.

[0023] The beneficial effects of this utility model are as follows: A lever motion structure is formed by connecting the support end and the column. The telescopic end of the lifting driver is hinged to one end of the material rack. When the lifting driver drives one end of the material rack to rise or fall, the end of the material rack connecting the top shaft and the tail top falls or tilts up, which facilitates the loading of the material rack and improves the convenience of feeding the coil. When the unwinding end of the coil passes through the rotating device and is conveyed to the material rack, the rotating device moves along the second moving component towards the opening direction due to the stretching of the unwinding coil, and simultaneously drives the slider electronic ruler to slide. Through the feedback signal of the slider electronic ruler, the unwinding drive drives the top shaft to rotate synchronously, so that the coil between the top shaft and the tail top is unwound synchronously, thereby further controlling the accuracy and stability of the unwinding conveyor, enhancing the use effect and the reliability of unwinding production.

The retractable drive rack 3 can perform lever movement along the support end 7 as the fulcrum. One end of the rack 3 is provided with a support frame 8. The support frame 8 is connected to a rotating device 300 for transmission and conveying via a guide mechanism. The guide mechanism includes a first moving component 400 and a second moving component 500. The first moving component 400 extends parallel to the axial direction of the top shaft 5. The second moving component 500 is mounted on the first moving component 400. The rotating device 300 is mounted on the second moving component 500. The rotating device 300 can move closer to or away from the opening 4 along the second moving component 500. The second moving component 500 is connected to the rotating device 300 via a slider-type electronic ruler 9.

[0039] Reference Figures 1-3 The column 2 is provided with a connecting bracket 10 for pairing and connecting the support end 7. The material rack 3 is paired with the connecting bracket 10 through the support end 7 and is hinged through the first hinge shaft.

[0040] The material rack 3 and the column 2 are hinged by the first hinge shaft. The support end 7 is connected to the connecting bracket 10 to form a fulcrum for supporting the material rack 3. With the lifting drive 200, the material rack 3 can be tilted up or down to realize the lifting action of the material rack 3. This makes it suitable for convenient lifting and loading of roll materials and improves the convenience of use.

[0041] Specifically, by connecting the support end 7 and the connecting bracket 10, the material rack 3 uses the support end 7 as a fulcrum, and the two ends of the material rack 3 can move in a lever-like manner, so that it can sink to feed materials and rise to be level with materials according to the feeding requirements.

The first moving assembly includes two sets of optical axes 401 arranged opposite to each other. The two sets of optical axes 401 are mounted on the support frame 8 through support seats 402.

[0050] Specifically, at the unwinding end of the roll material, under traction and tension, the rotating device 300 moves along the guide shaft 501 toward the material rack 3. After the unwinding drive 100 drives the roll material to unwind, the spring 504 provides a reset force to further control the tension and stability of the unwinding of the roll material.

[0057] The specific line-laying process in this embodiment is as follows:

[0058] Feeding: Place the rolled material (copper or aluminum busbar) on the support plate 15. Drive the screw of the screw jack 201 through the lifting drive motor 202 to push out, so that the material rack 3 is synchronously lifted and tilted through the end connected to the screw jack 201 via the connecting end 13. At this time, due to the fulcrum of the support end 7, one end of the material rack 3 connecting the top shaft 5 and the tail jack 6 is lowered. By adjusting the support plate 15, one end of the rolled material is brought into contact with the top shaft 5. By adjusting the extension and retraction of the tail jack 6 and locking it with the set screw, the rolled material can be clamped and fed, improving the convenience of loading the rolled material.

[0059] Unwinding: The material rack is reset to a horizontal position. The unwinding end of the coil (copper or aluminum busbar) is passed through the inlet 303 of the rotating device 300 and discharged from the outlet 304 through multiple rollers 302, so that it enters the subsequent bending machine. When the unwinding end is pulled and fed to the bending machine, the unwinding drive motor 102 is stationary. The copper busbar pulls and feeds the rotating device 300 along the guide shaft 501 through the bearing seat 502. At the same time, the bearing seat 502 drives the connecting rod 19 on the slider electronic ruler 9 to move along the slider electronic ruler 9. Specifically, the slider electronic ruler 9 is composed of a linear displacement sensor, which feeds back a signal to the external controller. After receiving the signal, the controller transmits a signal to the unwinding drive motor 102. The unwinding drive motor 102 provides rotational unwinding power to the top shaft 5, thereby further controlling the accuracy and stability of the unwinding conveyor, enhancing the use effect and the reliability of unwinding production.
