An inductor coil welding device based on inductor lead strip Technical Field

[0001] This invention relates to the field of inductor manufacturing technology, specifically to an inductor coil welding device based on inductor lead strip. Background Technology

[0002] An inductor coil welding device is used to weld inductor coils and inductor leads together. Existing inductor coil welding devices use two robotic arms to feed the inductor coils and inductor leads separately before welding. However, this technology has the following drawbacks: both the inductor coils and inductor leads are fed by robotic arms, requiring high precision in their feeding positions, and there is a risk of material leakage during operation, significantly impacting efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an inductor coil welding device based on inductor pin strip that can effectively avoid inductor pin leakage and has high working efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] An inductor coil welding device based on inductor lead strip includes a machine base, a tray, inductor lead strip, a strip feeding device, a strip displacement precision positioning device, an inductor coil loading robot, a lead welding device, and a coil end excess length cutting device. The inductor lead strip is wound on the tray, which is located at one end of the machine base. The inductor coil loading robot is used to place the inductor coil onto a lead welding fixture below the lead welding device. The lead welding device is used to weld the two ends of the inductor coil to the inductor leads respectively. The inductor front pin and inductor rear pin are soldered on the strip. The strip feeding device is used to drive the inductor pin strip to move intermittently, so as to move the inductor front pin and inductor rear pin on the inductor pin strip to the soldering station of the pin soldering device. The coil end excess length cutting device is used to cut off the two excess wire ends after soldering on the inductor coil. The strip displacement precision positioning device is used to control the strip feeding device so that the inductor front pin and inductor rear pin on the inductor pin strip can move forward precisely to the soldering station.

[0006] Furthermore, the inductor lead strip includes an aluminum strip, which is cut into a front edge longitudinal strip, a rear edge longitudinal strip, multiple transverse connecting strips, multiple inductor front leads, and multiple inductor rear leads. The front edge longitudinal strip is connected to the rear edge longitudinal strip through multiple transverse connecting strips. The multiple transverse connecting strips are parallel to each other and spaced apart. The multiple inductor front leads are spaced apart on the front edge longitudinal strip and extend towards the rear edge longitudinal strip.

The front positioning holes and the rear positioning holes correspond to each other.

[0007] Furthermore, the strip displacement precision positioning device includes a front through-beam photoelectric switch and a rear through-beam photoelectric switch. When the light from the front through-beam photoelectric switch and the rear through-beam photoelectric switch passes through the front positioning hole and the rear positioning hole on the inductor pin strip, respectively, the power supply of the strip feeding device is disconnected, causing the strip feeding device to stop working.

[0008] Further, the pin welding device includes a gantry frame, a left cylinder, a left lifting cylinder, a left electrode, a left arc welding power source, a left slider, a left vertical slide rail, a left clamp, a left welding rod, a right cylinder, a right lifting cylinder, a right electrode, a right arc welding power source, a right slider, a right vertical slide rail, a right clamp, and a right welding rod.

The left and right sliders are respectively located on the left and right vertical slide rails. The left and right vertical slide rails are respectively located on the left and right side walls of the gantry. When welding the rear pin of the inductor, the left lifting cylinder drives the left electrode to rise, so that the left electrode contacts the strip of the inductor pin. The left cylinder drives the left arc welding power source and the left welding rod to descend and weld the rear pin of the inductor to one end of the inductor coil. When welding the front pin of the inductor, the right lifting cylinder drives the right electrode to rise, so that the right electrode contacts the strip of the inductor pin.

The spring is fitted on the slide rod and is located between the drive plate and the knife holder. The cutting blade is located at the bottom of the knife holder, and the anvil is located on the support platform and directly below the cutting blade.

[0011] Furthermore, the two ends of the tool holder are fixed on the left guide seat and the right guide seat, the left guide seat and the right guide seat are respectively provided on the left vertical guide rail and the right vertical guide rail, and the left vertical guide rail and the right vertical guide rail are provided on the bracket.

[0012] Furthermore, a resilient front elongated hole is provided on the front edge longitudinal strip and at one end near the transverse connecting strip, and a resilient rear elongated hole is provided on the rear edge longitudinal strip and at the other end near the transverse connecting strip. The resilient rear elongated hole and the resilient front elongated hole are used to give the transverse connecting strip a certain degree of resilience.

[0013] Furthermore, the width of the plurality of transverse connecting strips is the same, the width of the inductor front pin and the inductor rear pin is the same, and the width of the inductor rear pin is not less than 5 times the width of the transverse connecting strips; the width of the aluminum strip is 10mm-50mm, and the thickness of the aluminum strip is 0.2mm-0.8mm.

[0014] Furthermore, the strip feeding device includes an electric push rod, a cylinder clamp, a guide block, and a guide rail. The electric push rod is used to push the guide block to slide along the guide rail. The guide rail is parallel to the inductor lead strip.
