Description

Technical Field

[0001] This utility model relates to the field of pin cutting devices, and in particular to an auxiliary device for cutting the pins of high-frequency power ceramic capacitors. Background Technology

[0002] As an extension of the capacitor, the chip leads are specially designed for circuit connection to ensure that the capacitor can be accurately connected to the circuit, thereby achieving effective storage and release of charge. When soldering high-RF power ceramic capacitors, the chip leads need to be appropriately cut and adjusted to adapt to specific soldering conditions and circuit board layout requirements.

[0003] Some traditional lead cutting methods involve workers using scissors and length measuring tools to cut off excess leads. However, scissors are difficult to control precisely in terms of cutting dimensions, which may lead to inconsistent lead lengths. This can affect the connection stability and electrical performance between the capacitor and the circuit board. Furthermore, scissor cutting often fails to guarantee the flatness of the lead cut surface. Uneven lead cut surfaces may increase contact resistance during soldering, affecting soldering quality and work efficiency.

[0004] Therefore, those skilled in the art have provided an auxiliary device for cutting the chip pins of high-RF power ceramic capacitors to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for cutting the chip leads of high-RF power ceramic capacitors. Compared to traditional auxiliary devices for cutting chip leads, this device uses a fixture to stably place the capacitor and uses the thickness of the fixture as a limit length to control the positional stability of the capacitor during processing. A handle is also designed to cut the chip leads using a lever principle. Furthermore, a reset groove is created on the blade, and a spring is installed inside the groove. The other end of the spring is mounted on a fixed base on the blade support sheet metal, allowing the blade to easily reset after cutting. This improves the operating efficiency and continuous working capability of the cutting device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An auxiliary device for cutting the chip pins of high-RF power ceramic capacitors includes a pressure support base, a handle, and a fixture support platform. The upper ends of the outer walls on both sides of the pressure support base are rotatably connected with pins. A blade support sheet metal is fixedly connected to the middle of the upper surface of the fixture support platform. A blade protection sheet metal is fixedly connected to the four sides of the outer wall of the front end of the blade support sheet metal. Square grooves are opened on the lower surfaces of both the blade support sheet metal and the blade protection sheet metal.

[0008] The outer rear wall of the blade protective sheet metal is provided with a protective groove, the inner wall of the protective groove is provided with a cutting blade, the outer wall of the cutting blade is provided with multiple reset grooves, the middle of the outer front wall of the blade support sheet metal is fixedly connected with multiple fixing seats, the upper surface of each fixing seat is fixedly connected with a spring, and the front end of the upper surface of the fixture support platform is provided with a capacitor to be cut.

[0009] Through the above technical solution, the auxiliary device for cutting capacitor chip leads uses a fixture support platform to stably place the capacitor to be cut, sets the thickness of the blade protective sheet metal as the cutting thickness, and after the handle drives the cutting blade to press down to cut, the cutting blade will automatically return to its original position by a spring, thereby completing the cutting operation that ensures the lead length.

[0010] Furthermore, a limiting post is fixedly connected to the upper surface of the cutting blade, and a handle limiting groove is provided at the lower end of the outer wall of the handle;

[0011] The above technical solution involves setting a limiting post and a limiting groove on the handle to cooperate, which facilitates the cutting blade to be driven to perform cutting operations when the handle is pressed down, and the cutting blade to be driven to return to its original position when the handle is lifted.

[0012] Furthermore, the outer walls of both the blade support sheet metal and the blade protective sheet metal are provided with multiple screw holes;

[0013] The above technical solution provides screw holes to facilitate the fixing of the blade support sheet metal and the blade protection sheet metal, allowing the two sheet metal pieces to better protect the cutting blade.

[0014] Furthermore, the end of the spring away from the fixed seat is fixedly connected to the inner top surface of the reset groove;

[0015] The above technical solution connects one end of the spring to a fixed base and the other end to a groove in the cutting blade, so that the spring can drive the blade to return to its original position after the blade is pressed down to complete the cutting action.

[0016] Furthermore, the end of each pin near the middle of the lower support is fixedly connected to the handle, thereby fixing the handle to the lower support.

[0017] The above technical solution provides a stable fulcrum for the handle, ensuring that the handle will not shake or shift during the application of force, thereby guaranteeing the accuracy and convenience of handle operation.

[0018] Furthermore, a downward pressure groove is formed on the upper surface of the downward pressure support;

[0019] The above technical solution involves setting a pressure groove, allowing the handle to move within the range of the pressure groove.

[0020] Furthermore, the downward support seat is fixedly connected to the rear end of the upper surface of the fixture support platform;

[0021] The above technical solution provides a pressure support base to secure the handle and support its movement.

[0022] Furthermore, a locking hole is provided at the rear end of the upper surface of the fixture support platform;

[0023] The above technical solution provides a locking hole to facilitate the fixing of the pressure support base and the fixture support platform, ensuring the stability of the pressure support base.

[0024] This utility model has the following beneficial effects:

[0025] This utility model proposes an auxiliary device for cutting the chip leads of high-RF power ceramic capacitors. Compared with most existing auxiliary devices for cutting chip leads, this auxiliary device for cutting chip leads uses a tooling fixture to place the capacitor stably, and uses the thickness of the tooling fixture as a limit length to control the positional stability of the capacitor during processing. It also features a handle that uses a lever principle to cut the chip leads, allowing workers to easily apply force.

[0026] This utility model proposes an auxiliary device for cutting the pins of high-RF power ceramic capacitors. Compared with most existing auxiliary devices for cutting the pins of capacitors, this auxiliary device for cutting the pins of capacitors has a reset groove on the blade, a spring inside the reset groove, and the other end of the spring is set on the fixed seat of the blade support sheet metal. This allows the blade to be easily reset after cutting, improving the working efficiency and continuous working capability of the cutting device. Attached Figure Description
