Description

Technical Field

[0001] This utility model relates to amorphous magnetic core production equipment, and more particularly to a tape feeding mechanism for an amorphous magnetic electric winding machine, belonging to the technical field of amorphous magnetic core production equipment. Background Technology

[0002] In the process equipment for winding amorphous magnetic cores using an electric automatic winding machine, after the winding spool is positioned at the set station, a feeding mechanism feeds the end of the strip into the V-shaped slot on the spool. Then, the spool action locks the strip to the narrowest part of the V-shaped slot. The rotation of the spool drives the strip to wind. After winding to the qualified diameter (number of turns), the cutting action cuts the strip. After external welding, internal welding, and blanking, the spool moves to the set station to wait for the next strip feeding. The strip feeding is accomplished by the feeding mechanism. Traditionally, the feeding mechanism uses a horizontal linear drive device (usually a horizontal cylinder) to drive the slider to feed the strip. The specific structure is as follows: a horizontal linear drive device is installed on the frame plate. The guide rail and slider are slidably fitted on the guide rail. An upper and lower drive device (usually an upper and lower cylinder) is fixedly installed on the slider. A pressure head for pressing the strip is installed on the actuating part of the upper and lower drive device. A support plate is fixedly connected to the slider below the pressure head. The amorphous strip passes through the support plate. A lower elastic clamping plate is fixedly connected to the front end of the support plate. An upper elastic clamping plate is fixedly connected above the lower elastic clamping plate. The strip is clamped between the two elastic clamping plates. When feeding the strip, the upper and lower cylinders drive the pressure head to descend and press the strip. The horizontal cylinder drives the slider to move forward. The strip clamped between the two elastic clamping plates moves forward synchronously and is fed into the V-shaped slot on the reel. Then, the actuating end of the upper and lower cylinders moves up to release the strip, and the horizontal cylinder retracts to drive the slider to reset. Traditional tape feeding mechanisms have the following problems: First, the drive device uses cylinders, which are noisy, and the start and stop of the cylinders have a significant impact on the equipment, requiring a pneumatic power source. Second, because the cylinders move abruptly, the sliding block pulls the tape behind it during forward movement, which can easily cause breakage of some brittle tapes during production, requiring manual tape threading to restore them. Frequent tape breaks significantly impact production efficiency and require increased personnel monitoring. To overcome the tape breakage problem, the applicant disclosed a dual-cylinder tape feeding device for amorphous tape winding in Chinese Patent 2017212326434. Although it can overcome the tape breakage problem to some extent, it increases the complexity of the equipment, generates more noise during operation, increases the number of actions required for the tape feeding mechanism to complete the operation, and affects the winding speed and cycle time. Furthermore, because the second tape feeding cylinder also pulls the tape behind it abruptly during operation, tape breakage can still occur in cases where the tape is brittle. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in existing amorphous magnetic core electric winding machines and to provide a tape feeding mechanism for an amorphous magnetic electric winding machine.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A tape feeding mechanism for an amorphous magnetic core electric winding machine includes a frame plate, a front-to-back guide rail fixedly installed on the frame plate, a slider fitted on the guide rail, an upper and lower driving device fixedly installed on the slider, a pressure head for pressing the tape installed on the actuating part of the upper and lower driving device, a support plate fixedly connected to the slider below the pressure head, the amorphous tape passing through the support plate, a lower elastic clamping plate fixedly connected to the front end of the support plate, an upper elastic clamping plate fixedly connected above the lower elastic clamping plate, the tape being clamped between the two elastic clamping plates, a reduction motor fixedly installed on the frame plate, the reduction motor connected to a controller, a U-shaped shift fork fixedly connected to the output shaft of the reduction motor, a drive plate fixedly connected to the slider, a drive rod fixedly connected to the drive plate, the drive rod being located inside the U-shaped opening of the U-shaped shift fork, and a gap between the drive rod and the two walls of the U-shaped opening.

[0005] Furthermore, the aforementioned geared motor is a servo geared motor.

[0006] Furthermore, the starting and stopping positions of the belt feeder are located on opposite sides of the vertical direction, with an angle of less than 180 degrees between them. During belt feeding, the U-shaped opening of the U-shaped fork rotates from the starting position to the stopping position, and during resetting, the U-shaped opening of the U-shaped fork rotates from the stopping position to the starting position.

[0007] Furthermore, during tape feeding, the U-shaped fork passes through the position where the U-shaped opening faces upwards.

[0008] The positive and beneficial technical effects of this utility model are as follows: Compared with the cylinder-driven belt feeding action, this mechanism is more stable and the noise is greatly reduced. The shift fork itself moves in a circular motion, while the belt feeding plate moves in a linear motion. In terms of the direction of movement speed, the speed is the maximum when the shift fork moves to 90° (up and down direction of the U-shaped opening). When the shift fork is close to 0° and 180° (horizontal direction of the U-shaped opening), the horizontal belt feeding speed approaches 0. In this way, it is easy to realize that the speed of the belt feeding mechanism decreases when starting and stopping, and the speed is the maximum when moving to the middle position. This makes the belt feeding action more gentle, and when winding some brittle belt materials, it no longer causes the belt to break due to the stiff action, unlike the previous cylinder.

[0014] A tape feeding mechanism for an amorphous magnetic core electric winding machine includes a frame plate 1. A front-to-back guide rail 2 is fixedly installed on the frame plate. A slider 3 is fitted on the guide rail 2. An upper and lower drive device 4 is fixedly installed on the slider 3. The upper and lower drive device can be an electric push rod, an electromagnet, etc. A pressure head 5 for pressing the tape is installed on the actuating part of the upper and lower drive device. A support plate 2 is fixedly connected to the slider below the pressure head 5. The amorphous tape passes through the support plate. A lower elastic clamping plate 7 is fixedly connected to the front end of the support plate. An upper elastic clamping plate 6 is fixedly connected above the lower elastic clamping plate. The tape is clamped between the upper elastic clamping plate and the lower elastic clamping plate. A geared motor, which is a servo geared motor 8, is fixedly installed on the frame plate. The geared motor is connected to a controller. A U-shaped shift fork 10 is fixedly connected to the output shaft of the geared motor. A drive plate 9 is fixedly connected to the slider. A drive rod 11 is fixedly connected to the drive plate 9. The drive rod 11 is located inside the U-shaped opening of the U-shaped shift fork, and there is a gap between the drive rod and the two walls of the U-shaped opening. When the geared motor drives the U-shaped fork to rotate, the U-shaped fork drives the drive rod to move linearly back and forth, thereby driving the slider to move back and forth. In this utility model, the starting position and the stopping position of the tape feed are located on opposite sides in the vertical direction, and the included angle between the starting position and the stopping position is less than 180 degrees. When feeding the tape, the U-shaped opening of the U-shaped fork rotates from the starting position to the stopping position. When resetting, the U-shaped opening of the U-shaped fork rotates from the stopping position to the starting position. When feeding the tape, the U-shaped fork passes through the position where the U-shaped opening is facing upwards. Figure 3 In the diagram, the solid line represents the starting position, and the dashed line represents the stopping position (i.e., the position when the strip is fed in). This mechanism operates on the same principle as existing strip feeding mechanisms. During feeding, the upper and lower drive devices lower the pressure head to press down on the strip, while the geared motor rotates to move the slider forward to the stopping position. The strip, clamped between the two elastic clamps, moves forward synchronously and is fed into the V-shaped slot on the reel. Then, the actuating end of the upper and lower drive devices moves upward to release the strip, and the geared motor flips to reset the slider.
