Description

Technical Field

[0001] This utility model relates to the field of diode processing technology, specifically to a pin cutting device for diode processing. Background Technology

[0002] A diode is an electronic component with unidirectional conductivity, consisting of a PN junction, corresponding electrode leads, and a housing.

[0003] In the manufacturing process of diodes, the length of diode leads needs to meet the product design standards. Therefore, a cutting device is required to cut the diode leads. However, different diodes have different lead size requirements. The cutting blade in the cutting device cannot adjust the blade pitch according to the lead size requirements. It can only produce leads of a single length and cannot flexibly adapt to different production needs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pin cutting device for diode processing, which has advantages such as adjustable blade spacing, thus solving the problem of non-adjustable blade spacing.

[0005] This utility model discloses a diode lead cutting device, comprising a base frame, with support plates fixedly mounted on both sides of the base frame, and a support platform fixedly mounted on the top of the four support plates. A cutting cylinder is fixedly mounted inside the support platform, and the output end of the cutting cylinder passes through the inner cavity of the support platform and is fixedly mounted with a blade spacing adjustment assembly. The blade spacing adjustment assembly includes a fixed frame, which is fixedly mounted on the output end of the cutting cylinder. A bidirectional screw is movably connected between the two sides of the inner cavity of the fixed frame. One end of the bidirectional screw extends through to the outside of the fixed frame and is fixedly mounted with a rotating handle. Screw sleeves are threaded onto both sides of the surface of the bidirectional screw. Transmission plates are fixedly mounted on the surfaces of two of the screw sleeves, and movable sleeves are fixedly mounted on both sides of the inner cavities of the two transmission plates. Two guide rods adapted to the movable sleeve are fixedly installed between the two sides of the inner cavity of the fixed frame. Cutting blades are fixedly installed at the bottom of the two transmission plates. The inner cavity of the bottom frame is equipped with a conveying assembly. When adjusting the blade distance between the two cutting blades, the operator rotates the handle, which drives the bidirectional screw to rotate. The bidirectional screw drives the two screw sleeves to move, which in turn drives the two transmission plates to move. The guide rods guide the movement direction of the transmission plates, and the movement of the two transmission plates drives the two cutting blades to move, thus adjusting the distance between the two cutting blades. By setting a blade distance adjustment assembly to adjust the blade distance between the cutting blades, the cutting blades can adapt to the cutting needs of pins of different lengths, increasing the adaptability and flexibility of production, thereby improving production efficiency.

[0006] This utility model discloses a lead cutting device for diode processing, wherein a limit screw is threadedly connected between the rotating handle and the fixed frame, and the surface of the fixed frame is provided with multiple limit screw holes adapted to the limit screw. By setting the limit screw, the stability of the rotating handle can be increased, and the rotating handle can be prevented from rotating during the cutting process, thereby affecting the cutting accuracy. By setting multiple limit screw holes, the flexibility of the limit screw in limiting is increased.

[0007] This utility model discloses a lead cutting device for diode processing. The cutting blade has fixed plates on both sides of its top, and the fixed plates are fixedly connected to the transmission plate by limit bolts. When the cutting blade is worn and needs to be replaced or maintained, the operator can rotate the limit bolts to release the limit between the fixed plate and the transmission plate, and then remove the cutting blade, which is convenient for the operator to maintain the cutting blade.

[0008] This invention discloses a diode lead cutting device, wherein the conveying assembly includes a drive motor, which is fixedly mounted on one side of a base frame. A rotating rod is rotatably connected to the output end of the drive motor, and one end of the rotating rod penetrates the inner cavity of the base frame and is movably connected to one side of the inner cavity. Both sides of the rotating rod's surface are fixedly fitted with drive gears, and toothed belts mesh with the surfaces of both drive gears. One end of each toothed belt is connected to a transmission gear. Limiting rods are movably connected to the inner cavities of the two transmission gears, and both ends of the limiting rods are fixedly connected to the sides of the inner cavity of the base frame. Multiple receiving grooves are formed on the surface of the toothed belts. Material is embedded in the receiving grooves. When the drive motor is started, it drives the rotating rod to rotate, which in turn drives the drive gears to rotate. The drive gears then drive the toothed belts, which in turn drive the transmission gears and limiting rods in conjunction with the toothed belts. This toothed belt drive moves the material embedded in the receiving grooves. By setting up the conveying assembly, material loading and unloading time is saved. By setting up multiple receiving grooves, multiple materials can be accommodated, enabling batch cutting of materials and improving production efficiency.

[0009] This utility model discloses a lead cutting device for diode processing. The device includes electric telescopic rods fixedly installed on both sides of the inner cavity at the top of the bottom frame, and a limiting plate fixedly installed between the output ends of the two electric telescopic rods. To increase the stability of material cutting, the electric telescopic rods are activated, and the limiting plate is moved downward through the electric telescopic rods. When the limiting plate moves downward to contact the surface of the material, it can limit the material and prevent the material from shaking during cutting, thereby reducing the material processing accuracy.

[0010] This utility model discloses a diode lead cutting device, wherein electric push rods are fixedly installed on both sides of the bottom of the inner cavity of the base frame, and a support platform is fixedly installed between the output ends of the two electric push rods. When cutting the material, the electric push rods are activated, driving the support platform to move upward. When the support platform moves upward to contact the material, the cutting cylinder is activated, driving the blade distance adjustment component to move downward. The downward movement of the blade distance adjustment component drives the cutting blade to move downward, thereby cutting the material. By setting up a support platform to work with the cutting blade, the material can be supported when the cutting blade cuts the material, further increasing the stability of the material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this invention, when adjusting the blade spacing of the two cutting blades, the operator rotates the handle, which in turn drives the bidirectional screw to rotate. The bidirectional screw then moves the two threaded sleeves, which in turn move the two transmission plates. A guide rod guides the movement of the transmission plates, and the movement of the two transmission plates moves the two cutting blades, thus adjusting the distance between the two cutting blades. By setting a blade spacing adjustment component to adjust the blade spacing, the cutting blades can adapt to the cutting needs of pins of different lengths, increasing the adaptability and flexibility of production, thereby improving production efficiency.

[0012] 2. By setting a limiting screw, this utility model can increase the stability of the rotating handle and prevent the rotating handle from rotating during the cutting process, thereby affecting the cutting accuracy. By setting multiple limiting screw holes, the flexibility of the limiting screw is increased. When the cutting blade is worn and needs to be replaced or maintained, the operator can turn the limit bolt to release the limit between the fixing plate and the transmission plate, and then remove the cutting blade for easy maintenance. The material is embedded in the receiving slot. The drive motor starts and drives the rotating rod to rotate. The rotating rod drives the drive gear to rotate. The drive gear drives the toothed belt drive. The toothed belt drive, in conjunction with the transmission gear and the limit rod, moves the material embedded in the receiving slot. The material loading and unloading time is saved by setting up the conveying component. Multiple receiving slots can accommodate multiple materials, enabling batch cutting of materials and improving production efficiency. To increase the stability of material cutting, the electric telescopic rod is activated, which drives the limit plate to move downward. When the limit plate moves downward to contact the material surface, it can limit the material and prevent the material from shaking during cutting, thereby reducing the material processing accuracy. When cutting materials, the electric push rod is activated, which drives the support platform to move upward. When the support platform moves upward to contact the material, the cutting cylinder is activated, which drives the blade distance adjustment component to move downward. The downward movement of the blade distance adjustment component drives the cutting blade to move downward, thus cutting the material. By setting up a support platform to work with the cutting blade, the material can be supported during the cutting process, further increasing the stability of the material.

[0018] The top of the cutting blade 6 is fixedly provided with fixing plates 510 on both sides, and the fixing plates 510 are fixedly connected to the transmission plate 505 by limiting bolts 511.

When cutting the material, the electric push rods 9 are activated, which drives the support platform 8 to move upward. When the support platform 8 moves upward to contact the material, the cutting cylinder 4 is activated, which drives the blade distance adjustment component 5 to move downward.

By setting the support platform 8 to work with the cutting blade 6, the material can be supported when the cutting blade 6 is cutting the material, which further increases the stability of the material.

[0022] When using this invention: When adjusting the blade spacing of the two cutting blades 6, the operator rotates the handle 503, which in turn drives the bidirectional screw 502 to rotate.
