Description

Technical Field

[0001] The present invention relates to the technical field of transformer coil processing equipment, and particularly relates to a numerical control copper strip substituting foil tape feeding machine. Background Art

[0002] The existing foil winding method for transformer coils is made by winding a whole piece of copper foil or aluminum foil. Since metal foil plates of corresponding widths are required to make coils of different widths, enterprises must customize specific metal foil plates according to the specific size requirements of each order. However, the processing cost of metal foil plates is expensive and the processing cycle is long, resulting in a long delivery cycle, high costs, and a large amount of enterprise working capital being occupied.

[0003] To solve the above problems, people have invented a method of using multiple copper strips (aluminum strips) to replace the whole piece of copper foil (aluminum foil). In this way, the number of copper strips can be selected according to different coil specifications, shortening the supply cycle, and the processing cost of copper strips is low. However, when the copper strips are wound, one or several copper strips may be bent or curled to a certain extent, which greatly affects the coil quality and thus the performance of the transformer. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the copper strips in the prior art will be bent to a certain extent and affect the coil quality, so as to provide a numerical control copper strip substituting foil tape feeding machine with high reliability.

[0005] For this purpose, the present invention provides a numerical control copper strip substituting foil tape feeding machine, which includes a reel mechanism, a numerical control voltage regulating mechanism, a copper strip flat pressing mechanism, and a numerical control micro-distance deviation correcting mechanism. The reel mechanism is arranged at the rear side of the frame and has a reel for installing multiple copper strip coils; the numerical control voltage regulating mechanism is arranged in the middle of the frame and is suitable for flattening the copper strip and adjusting the tension of the copper strip; the copper strip flat pressing mechanism is arranged at the front side of the frame and is suitable for pressing the copper strip flat; the numerical control micro-distance deviation correcting mechanism is arranged on the frame and is suitable for correcting the position of the copper strip.

[0006] The numerical control voltage regulating mechanism includes a pressing wheel and a first driving mechanism. The pressing wheel is arranged above multiple copper strips and can be in contact with the copper strips; the first driving mechanism is connected to the pressing wheel and is suitable for driving the pressing wheel to move up and down.

[0007] The first driving mechanism includes a support plate and a longitudinal driving mechanism. Two side plates suitable for installing the pressing wheel are arranged on the left and right sides of the support plate, and a gap for the copper strip to pass through is arranged between the support plate and the pressing wheel; the longitudinal driving mechanism is arranged below the support plate and is connected to the support plate, and the longitudinal driving mechanism is suitable for driving the support plate to move up and down.

[0008] Guide structures are provided on both sides of the support plate. The guide structures include guide rods and mounting holes. The guide rods are arranged along the vertical direction. The mounting holes are arranged on the support plate and can be used for the guide rods to pass through.

[0009] The copper strip flattening mechanism comprises: an upper pressing plate and a lower pressing plate, which are arranged opposite to each other up and down; and a driving cylinder, which is connected to the upper pressing plate and is suitable for driving the upper pressing plate to move up and down.

[0010] The frame is slidably mounted on the bottom plate via a slide rail structure, wherein the slide rail structure comprises a plurality of slide rails arranged on the bottom plate, and a sliding block arranged at the bottom of the frame and slidably connected to the slide rails.

[0011] The CNC macro deviation correction mechanism includes a driving motor, a transmission gear and a rack. The driving motor is fixed on the frame, and a power output shaft is provided at one end of the driving motor; the transmission gear is provided on the power output shaft and follows the power output shaft in linkage; the rack is fixed on the base plate and arranged along the width direction of the base plate, and the rack is meshed and connected with the transmission gear.

[0016] 1. The CNC foil unwinding machine provided by the present invention comprises a reel mechanism, a CNC pressure regulating mechanism, a copper strip flattening mechanism and a CNC micro-pitch deviation correction mechanism. When unwinding the strip, the CNC pressure regulating mechanism first flattens the bent or curled copper strip and adjusts the tension of the copper strip at the same time. Then the copper strip flattening mechanism further flattens the copper strip flattened by the CNC pressure regulating mechanism. Compared with the prior art, this makes the copper strip tightly wound and ensures the coil quality. In addition, the CNC micro-pitch deviation correction mechanism can calibrate the position of the copper strip to prevent the copper strip from deviating, thereby reducing downtime and improving production efficiency.

[0017] 2. The CNC foil unwinding machine provided by the present invention includes a CNC pressure regulating mechanism including: a pressure wheel, which is arranged above the plurality of copper strips and can contact the copper strips; a first driving mechanism, which is connected to the pressure wheel and is suitable for driving the pressure wheel to move up and down. When the pressure wheel is pressed down, its arc surface contacts the copper strip, which can make the bent or curled copper strip flat, and the arc surface is not easy to damage the copper strip, thus ensuring the quality of the coil; in addition, the pressure wheel can also keep a certain tension on the copper strip, making the copper strip winding more compact.

[0018] 3. The CNC foil unwinding machine provided by the present invention comprises a first driving mechanism including a support plate and a longitudinal driving mechanism. Two side plates suitable for installing pressure wheels are provided on both sides of the support plate. A gap is provided between the support plate and the pressure wheel for the copper tape to pass through. When the longitudinal driving mechanism drives the support plate to move downward, the pressure wheel is driven to contact the copper tape.

[0019] 4. The CNC foil unwinding machine provided by the present invention includes a CNC micro-distance correction mechanism, which includes: a driving motor fixed on the frame, one end of which is provided with a power output shaft; a transmission gear, which is provided on the power output shaft and follows the power output shaft in linkage; a rack, which is fixed on the bottom plate and arranged along the width direction of the bottom plate, and the rack is meshed with the transmission gear. When correcting the deviation, the motor drives the transmission gear to rotate relative to the rack, thereby driving the frame to slide relative to the bottom plate. The CNC micro-distance correction mechanism has the advantage of simple structure. BRIEF DESCRIPTION OF THE DRAWINGS
