Description

Technical Field

[0001] This invention relates to the field of inductor manufacturing technology, specifically to a pin bending machine for an integrated inductor. Background Technology

[0002] In inductor manufacturing, the lead bending machine for integrated inductors bends the leads on the integrated inductor after it has been molded from powder, causing the leads on both sides of the inductor to flip up and press against the top surface of the inductor.

[0003] Existing inductor pin bending machines can only process one inductor at a time, which is not only inefficient but also complex in structure and cannot be effectively integrated into the inductor production line. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated inductor pin bending machine with high working efficiency, which can be effectively connected to the inductor production line.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated inductor lead bending machine includes an intermittent turntable. Multiple through holes are distributed circumferentially on the surface of the turntable, and a fixture is disposed in each through hole. The periphery of the intermittent turntable is sequentially arranged with a feeding station, a strip bending station, a strip cutting and removal station, a lead bending and gathering station, a lead flattening station, and a finished inductor unloading station. The feeding station, strip bending station, strip cutting and removal station, lead bending and gathering station, lead flattening station, and finished inductor unloading station are respectively... The system includes a loading robot, a strip bending device, a strip cutting and removal device, a lead bending and gathering device, a lead flattening station device, and a finished inductor collection box. The loading robot moves a section of inductor strip cut from the cutting table to a fixture at the loading station. The fixture is used to lock and fix each inductor on the strip. Powered by a motor, the intermittent turntable rotates one station, moving the inductor strip to the strip bending station. The strip bending device bends the strip on both sides of the inductor upwards by 90°, so that each inductor... The pins are bent 90°; the intermittent turntable rotates one station, moving the bent inductor strip to the strip cutting and removal station. The strip cutting and removal device cuts the connection point between each inductor pin and the strip to separate the inductor from the strip, and moves the strip without inductance to the waste collection box; the intermittent turntable rotates one station, moving the inductor with strip removed to the pin bending and gathering station. The pin bending and gathering device gathers the free ends of each inductor pin towards the center of the inductor, so that... The free end of the pin is located directly above the inductor and close to the middle of the inductor; the intermittent turntable rotates one station, moving the inductor with the pin gathered to the pin flattening station. The pin flattening station device presses the pin down so that the pin is in close contact with the top surface of the inductor, forming a finished inductor; the intermittent turntable rotates one station, moving the finished inductor to the finished inductor unloading station. The fixture unlocks each finished inductor and flips it at a preset angle, causing the finished inductor to fall downward into the finished inductor collection box.

[0006] Furthermore, the fixture includes a vacuum seat, a rotating shaft, a support, a fixture motor, a vacuum pumping pipeline, and a vacuum pump. The vacuum seat is mounted on the rotating shaft, which is mounted on the support via bearings. The support is mounted on the bottom surface of the intermittent turntable. The fixture motor drives the rotating shaft to rotate at a preset angle. The vacuum seat contains a vacuum chamber, and its surface has multiple adsorption holes communicating with the vacuum chamber. These adsorption holes are used to attract the inductance on the inductor strip. The rotating shaft contains a vacuum pumping channel, which communicates with the vacuum chamber within the vacuum seat. The vacuum pump is connected to the vacuum pumping channel via a vacuum pumping pipeline. The vacuum pumping pipeline is equipped with a three-way solenoid valve, one of which is a pressure relief port.

[0007] Furthermore, the strip bending device includes a strip bending frame, a strip bending cylinder, a clamping cylinder, a left clamping long strip block, and a right clamping long strip block. The strip bending cylinder is vertically mounted on the strip bending frame. The clamping cylinder is mounted on the lower end of the piston rod of the strip bending cylinder and is located directly above the vacuum seat in the fixture. The left and right clamping long strip blocks are mounted on the left and right piston rods of the clamping cylinder, respectively. During strip bending, the fixture rotates 180 degrees. To bend the inductor strip downwards, activate the strip bending cylinder to drive the clamping cylinder to descend. The left and right clamping blocks press down on the strips on both sides of the inductor, bending them downwards. Activate the clamping cylinder to move the left and right clamping blocks towards each other, pressing the leads on the strips on both sides of the inductor tightly against the sidewalls of the inductor. After the strip bending cylinder and clamping cylinder reset, the fixture rotates 180°, completing the 90° upward bending of the strips on both sides of the inductor.

[0008] Furthermore, the lower ends of the left and right clamping strips are chamfered.

[0009] Furthermore, the strip cutting and removal device includes a cutting frame, a cutting lifting cylinder, a cutting anvil, a clamping cylinder, a left clamping block, and a right clamping block. The cutting frame includes a base, a rotatable column, and a crossbeam. The rotatable column is mounted on a vertical shaft at the top of the base, and the vertical shaft is driven by a motor inside the base. The crossbeam is located at the top of the rotatable column. The cutting lifting cylinder is located on the crossbeam. The left and right clamping blocks are mounted on the left and right piston rods of the clamping cylinder, respectively. The cutting anvil is mounted in the middle of the bottom surface of the clamping cylinder. The clamping cylinder is mounted at the lower end of the piston rod of the cutting lifting cylinder and is located directly above the vacuum seat in the fixture at the strip cutting and removal station. The bottom surfaces of the left and right clamping blocks are respectively positioned opposite to... Multiple left and right micro-cutting cylinders should be provided. The piston rod ends of the left and right micro-cutting cylinders are respectively equipped with left and right knife holders. The left and right knife holders are respectively equipped with left and right cutting blades. The left and right clamping blocks cooperate with the cutting anvil to clamp and fix the strip on both sides of the inductor. The left and right cutting blades cooperate with the cutting anvil to cut at the connection point between the inductor lead and the strip, so that the inductor is separated from the strip. When the cutting is completed, the cutting lifting cylinder drives the clamping cylinder to rise, and the vertical shaft drives the rotatable column to rotate, rotating the clamping cylinder above the waste collection box. The clamping cylinder is then reset, and the strip separated from the inductor falls into the waste collection box.

[0010] Furthermore, the cutting board is a cutting limiting plate. During cutting, the lower end of the cutting limiting plate contacts the upper surface of the inductor, and the height of the cutting limiting plate is used to limit the cutting position.

[0011] Furthermore, the lower end of the cutting board has a V-shaped chamfer.

[0012] Furthermore, the pin bending and gathering device has the same structure as the strip bending device.

[0013] Furthermore, eight inductors are distributed on the inductor strip.

[0014] The beneficial effects of this invention are as follows:

[0015] This lead bending machine can bend eight inductors in a single operation, greatly improving work efficiency and enabling effective assembly line connections on inductor production lines. Furthermore, the machine eliminates the need for a material unloading robot, resulting in a simple structure, low cost, and easy maintenance. Attached Figure Description
