Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing equipment, in particular to an automatic pin cutting device for transformer components. Background Art

[0002] Among electronic components, transformers are one of the more commonly used. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It typically consists of a primary coil, also known as the primary side or primary side, a secondary coil, also known as the secondary side or secondary side, and an iron core, also known as a magnetic core. When an AC current flows through the primary coil, an AC magnetic flux is generated in the iron core. This flux passes through the secondary coil, inducing a voltage or current in the secondary coil. This process achieves a voltage transformation and may also be accompanied by a transformation in current and impedance.

[0003] Transformers are widely used in various fields such as industry, agriculture, transportation, urban communities, and household electricity. At the same time, they are also used in various electronic devices and industrial control systems to achieve precise control of voltage and current. Typically, transformers used in various electronic devices or industrial control systems are chip-type assembly structures. In this structure, in addition to the aforementioned primary coil, secondary coil, and magnetic core, a base for assembly connection to the PCB surface and pins for insertion into the PCB are often provided. In the final stage of the production of this type of transformer, the pins of different lengths on the transformer need to be cut neatly. This process is also called the pin cutting process.

[0004] Based on this, Chinese patent CN117012533B discloses a pin cutting process system for a transformer production line, which includes a first linear conveying unit and a second linear conveying unit, and a transformer pin cutting and tinning unit is arranged between the conveying end of the first linear conveying unit and the conveying starting point of the second linear conveying unit; a slide rail is arranged above the transformer pin cutting and tinning unit, and a slider is arranged on the slide rail, and a manipulator is connected to the bottom of the slider through a lifter; the transformer pin cutting and tinning unit can continuously perform cutting and tinning processes on the pins of the transformer, thereby solving the shortcomings of the existing pin cutting process and tinning process being at different workstations, such as low equipment utilization, low process continuity, and large space occupation.

[0005] However, the cutting process system of the transformer production line disclosed above still has the technical problem of easily damaging the transformer components. Specifically, the cutting processing principle of the cutting process system disclosed above is: the robot drives the transformer to be cut down, so that the first row of pins and the second row of pins on the transformer to be cut are respectively inserted downward into the first row of pin through holes and the second row of pin through holes; then, the robot is released, and the transformer to be cut continues to descend under the action of gravity until the bottom of the coil skeleton of the transformer to be cut drops to contact the advance support platform; thereafter, the subsequent cutting tool is used to cut the pin. It can be seen that in this kind of cutting process system, it is necessary to confine the transformer and the pins in the fixture at the same time, and the robot needs to directly clamp the body of the transformer; usually, the transformer will be wrapped with a coil group, and the coil group will easily be deformed during the clamping process, affecting the electrical performance of the transformer. Moreover, the setting of the robot also has the problem of high usage cost. Utility Model Content

[0029] Please also refer to Figures 1 to 5 The utility model provides an automatic pin cutting device for transformer components, comprising: a frame 1, a stepping conveying mechanism 2, a pin cutting action mechanism 3, a clamping action mechanism 4 and a blanking conveying mechanism 5; the stepping conveying mechanism 2 is arranged on the frame 1, the pin cutting action mechanism 3 is arranged on one side of the stepping conveying mechanism 2, and the clamping action mechanism 4 is arranged on the other side of the stepping conveying mechanism 2; the blanking conveying mechanism 5 is arranged adjacent to the clamping action mechanism 4 on the frame 1, and the blanking conveying mechanism 5 is drivingly connected to the clamping action mechanism 4.

[0030] Specifically, when the automatic pin-cutting device for transformer components of the present invention is in operation, several transformer components to be pin-cut are pre-arranged and connected in series on a material strip, and the edge of the material strip is uniformly provided with several evenly distributed through-holes. At this time, the step-by-step conveying mechanism 2 provided on the frame 1 is activated and, by matching the through-holes on the material strip, drives the material strip and the transformer to be fed step by step. More specifically, the material strip can be connected to the edge of the base or pins of the transformer, thereby enabling the step-by-step conveying mechanism 2 to achieve the required positional movement of the transformer without having to clamp the transformer body. Thereafter, when the transformer to be pin-cut enters the working range of the cutting mechanism 3, the cutting mechanism 3 is activated and cuts the transformer pins within its processing range to ensure that the transformer pins are flush and meet the preset size requirements. Simultaneously, a section of the material strip connected to the side base of the transformer is also cut. Next, the trimmed transformer and its strip are pushed by the next component to be processed and enter the working range of the clamping mechanism 4. At this point, the clamping mechanism 4 clamps the strip connected to the side of the trimmed transformer. The blanking transfer mechanism 5 then activates and pushes the clamping mechanism 4 forward one station, allowing it to carry the clamped strip and the trimmed transformer to the blanking station. The clamping mechanism 4 then releases the clamped strip, allowing the processed transformer to fall into a preset position. Afterwards, the blanking transfer mechanism 5 drives the clamping mechanism 4 back to its original position, awaiting the next material to be clamped. It can be seen that the stepping transfer mechanism 2 provided in the automatic cutting device for transformer components of the utility model can avoid directly clamping the main body of the transformer component, so as to avoid accidental damage to components such as the transformer coil group; thereafter, the cutting action mechanism 3 automatically cuts and processes materials such as the transformer, and the clamping action mechanism 4 carries the processed materials and then carries out blanking turnover by the blanking transfer mechanism 5; thereby, the setting of the traditional manipulator is saved, the mechanism cost is saved, and the yield rate of the transformer components is improved, thereby improving the efficiency of the transformer component cutting processing.

[0031] Furthermore, the stepping transfer mechanism 2 comprises a stepping transfer base 201, a material strip movable inlay groove 202, a detachable stop bar 203, a ratchet structure 204, a ratchet drive motor 205, a stepping motor support frame 206, a counting rotation structure 207 and a stepping counting sensor 208; the stepping transfer base 201 is fixedly arranged on the frame 1, the material strip movable inlay groove 202 is arranged on the stepping transfer base 201, and the detachable stop bar 203 is adjacent to the material strip movable inlay groove 202 is movably arranged on the stepping transfer base 201; the ratchet structure 204 is movably arranged above the material strip movable inlay groove 202, and the ratchet drive motor 205 is driven and connected to the ratchet structure 204; the stepping motor support frame 206 is fixedly connected to the frame 1 on the adjacent side of the stepping transfer base 201, the counting rotation structure 207 is linked with the ratchet structure 204, and the step counting sensor 208 is arranged below the counting rotation structure 207.

[0032] Specifically, when installing the material strip, the user can first remove the detachable stop bar 203 from the step-by-step transfer base 201, and the material strip connected to the plurality of transformers to be processed, which is to be driven by the step-by-step transfer mechanism 2, can be movably inserted into the material strip movable insertion groove 202. Afterwards, the user reinstalls the detachable stop bar 203 on the step-by-step transfer base 201, so that the material strip connected to the plurality of transformers is confined in the material strip movable insertion groove 202. At this time, the plurality of spike-shaped structures on the edge of the ratchet structure 204 are aligned with the plurality of positioning holes on the material strip. Afterwards, the ratchet drive motor 205 is started and drives the ratchet structure 204 to rotate to a preset angle. When the ratchet structure 204 rotates, the spikes on its edge can drive the material strip to move along the material strip movable insertion groove 202 to a preset distance. This is a process step, which can position the pins of a transformer to be processed below the pin cutting mechanism 3. At the same time, the counting rotating structure 207 also rotates to another preset angle following the ratchet structure 204. Since the counting rotating structure 207 is a disc-shaped structure as a whole, a notch with a preset arc is provided on it. When the notch passes through the sensing range of the step counting sensor 208, the step counting sensor 208 can realize the counting function; thereby, the user can accurately locate the working step of the material belt conveying transformer forward.

[0034] Specifically, after the cutting drive cylinder 305 is started, it can drive the cutting push rod 304 to extend or shorten; and when the cutting push rod 304 is extended, it can push one end of the swing arm structure 302 to lift, and make the swing arm structure 302 move along the hinge between it and the swing support 303, so that the connecting end of the swing arm structure 302 and the cutting tool 301 is pressed down, and then drive the cutting tool 301 to cut off the pin of the transformer to be processed and the material strip of the connecting section at the same time; thereafter, the cutting drive cylinder 305 drives the cutting push rod 304 to retract, so that the connecting end of the swing arm structure 302 and the cutting tool 301 is lifted and reset.

The clamping lower jaw 401 is fixedly connected to the end of the transfer sliding block 502 adjacent to the material strip movable embedding groove 202. The clamping support frame 404 is disposed on the transfer sliding block 502.

[0037] Specifically, the material strip segment and transformer that have been cut and processed by the cutting mechanism 3 are pushed out by the next workpiece from the discharge end of the material strip movable embedding slot 202 and enter between the lower clamping jaw 401 and the upper clamping jaw 402. Thereafter, the clamping drive cylinder 406 is activated to drive the clamping telescopic rod 405 to extend, thereby pushing the upper jaw linkage 403 and driving the upper clamping jaw 402 toward the lower clamping jaw 401, thereby clamping the cut material strip segment between the upper clamping jaw 402 and the lower clamping jaw 401.
