Description

Technical Field

[0001] This utility model relates to the field of shearing and bending technology, specifically to a MOS transistor processing and forming equipment. Background Technology

[0002] MOSFET, short for Metal-Oxide-Semiconductor Field-Effect Transistor, is one of the core semiconductor devices in modern electronic circuits. It is equivalent to an "electronic switch" or "signal amplifier" in the circuit and is widely used in almost all electronic devices such as mobile phones, computers, home appliances, and industrial equipment. In the MOSFET manufacturing process, lead bending is a key process that determines the compatibility of the device in subsequent assembly and the stability of electrical connections. It is necessary to ensure the accuracy of the bending angle, the deviation of the bending position, and the absence of defects such as cracks and deformations in the leads.

[0003] Existing technologies typically use a single cutter to apply shearing force to multiple pins simultaneously. When cutting with a single cutter, multiple pins are subjected to shearing force at the same time, which can easily cause stress dispersion on the pins, leading to pin damage. This damage will directly affect the conductivity and soldering reliability of the pins, resulting in a decrease in the processing quality of the MOSFET.

[0004] Therefore, we provide a MOS transistor processing and forming equipment. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a MOS transistor processing and forming device, comprising a base, a groove fixedly formed at the top of the base, slide rails fixedly connected to both sides of the groove, a through hole fixedly formed at the top of the base and in front of the groove, a collection drawer provided inside the base and below the through hole, a baffle fixedly connected to the right side of the collection drawer, a support platform fixedly connected to the front end of the top of the base, a placement groove fixedly formed at the top of the support platform, a plurality of workpieces arranged equidistantly in a straight line inside the placement groove, a bending mechanism provided above the support platform, and a cutting mechanism provided at the rear end of the top of the base.

[0006] In some embodiments, the cutting mechanism includes a fixed plate fixedly connected to the rear end of the top of the base. Mounting ears are fixedly connected to both sides of the rear end of the fixed plate. An electric push rod is fixedly connected to the rear end of the fixed plate. A mounting block is fixedly connected to the output end of the electric push rod. A movable plate is fixedly connected to the front end of the mounting block. A plurality of equidistant mounting slots are fixedly opened at the front end of the movable plate. A plurality of cutters are fixedly connected inside each mounting slot. A fixed horizontal plate is fixedly connected to the front end of the top of the movable plate. A limit plate is fixedly connected to the bottom front end of the fixed horizontal plate. Slider blocks are fixedly connected to both sides of the bottom of the movable plate.

[0007] In some embodiments, the position of the cutter corresponds to the position of the workpiece, and the number of sets of cutters corresponds to the number of workpieces.

[0008] In some embodiments, the fixing plate is fixedly connected to the top of the base via mounting ears provided on both rear sides.

[0009] In some embodiments, the movable plate is slidably connected to the slide rails on the left and right sides inside the groove via sliders on both sides of the bottom.

[0010] In some embodiments, the position of the cutter corresponds to the position of the through hole.

[0011] In some embodiments, the bending mechanism includes a support frame fixedly connected to the top of the base and located on both sides of the support platform. A support plate is fixedly connected to the top front end of the support frame. A hydraulic device is fixedly connected to the front end of the support plate. A hydraulic rod is fixedly connected to the output end of the hydraulic device. A connecting block is fixedly connected to the bottom of the hydraulic rod. A moving platform is fixedly connected to the bottom of the connecting block. A protrusion is provided at the bottom of the moving platform. A bending block is fixedly connected to the bottom of the moving platform and at the rear end of the protrusion. Connecting rods are provided on both sides of the top of the moving platform.

[0014] In some embodiments, a control panel is fixedly connected to the front end of the base, and a protective cover is fixedly connected to the top of the base by a latch.

[0015] This utility model has at least the following beneficial effects: This invention utilizes a cutting mechanism. After the pins are bent by the bending mechanism, an electric push rod pushes the movable plate forward. Under the limiting action of the slider and the slide rail, the movable plate slides forward in a straight line. At this time, multiple cutters individually cut each corresponding pin. Simultaneously, the limiting plate abuts the pins to prevent them from lifting during cutting and also prevents the cut pins from bouncing upwards. This ensures that the cut pins fall directly into the through hole and are then collected in a collection drawer, avoiding dirt on the base surface and facilitating cleaning. By using a single cutter to cut the pins one-to-one, the cutting force can be applied to multiple pins simultaneously, resulting in stress concentration and preventing stress dispersion on the pins, which could damage them. This improves the conductivity and welding reliability of the pins, further enhancing the processing quality. Attached Figure Description

[0020] The cutting mechanism 4 includes a fixed plate 401 fixedly connected to the rear end of the top of the base 1. Mounting ears 402 are fixedly connected to both sides of the rear end of the fixed plate 401. An electric push rod 403 is fixedly connected to the rear end of the fixed plate 401.
