Description

Technical Field

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

[0002] A diode pin positioning and cutting device is a piece of equipment used to accurately determine the position and cut diode pins. It mainly consists of a positioning mechanism, a cutting mechanism, a drive mechanism, and a control system. It is widely used in the electronics manufacturing industry and can improve the accuracy and efficiency of diode pin cutting, reduce human error, and improve product quality and production efficiency.

[0003] By employing precision positioning fixtures, positioning slots, or vision recognition systems, diodes can be accurately fixed in predetermined positions, ensuring high accuracy in lead trimming positions and effectively controlling the tolerance range of lead trimming lengths to meet the high precision requirements of different electronic devices for diode lead dimensions.

[0004] In the diode pin positioning and cutting device, cutting tools such as scissors cutters cut or shear the pins during the cutting process. The cutting edge of the blade cuts the metal of the pin and produces cutting debris, which is mostly in the shape of small flakes or filaments. The debris is small in size and easily adheres to the blade edge and the surrounding surface. If the metal debris generated during the cutting process is not cleaned in time, the debris will be trapped between the blade and the pin or adhere to the blade surface, which will increase the frictional resistance of the blade in the subsequent cutting process, accelerate the wear of the blade edge, and shorten the service life of the blade.

[0005] Therefore, a diode pin positioning and cutting device is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a diode pin positioning and cutting device to solve the problem that if metal debris generated during the cutting process is not cleaned in time, the debris will be trapped between the cutter and the pin, or adhere to the surface of the cutter, which will increase the frictional resistance of the cutter in the subsequent cutting process, accelerate the wear of the cutter edge, and shorten the service life of the cutter.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A diode pin positioning and cutting device includes a control device 1. A cutting tool auxiliary seat 6 is fixedly connected to the upper end of the control device 1, and a cleaning device 5 is fixedly connected to the upper end of the cutting tool auxiliary seat 6. The cleaning device 5 includes a support frame 51, a transmission chamber 52 is formed inside the support frame 51, a guide tube 53 is fixedly connected to the center of the transmission chamber 52, a one-way valve 54 is fixedly connected to the inner side of the upper end of the guide tube 53, and a first piston 56 is slidably connected to the inner side of the lower end of the guide tube 53. The lower end of the first piston 56 is fixedly... A guide rod 55 is fixedly connected to the upper end of the scissor-type cutter 4. Guide shells 511 are fixedly connected to both ends of the transmission chamber 52. A piston rod 58 is slidably connected to the inner side of the guide shell 511. An air column 59 is fixedly connected to the bottom of the piston rod 58. A compression spring 57 is fixedly connected to the upper end of the piston rod 58. An air hole 510 is opened on the outer side of the air column 59. The upper end of the compression spring 57 is fixedly connected to the inner side of the transmission chamber 52. The lower end of the air column 59 is in contact with the upper end of the scissor-type cutter 4.

[0030] As a further implementation of the above technical solution: two piston rods 58 and two guide shells 511 are provided. The inner side of the piston rod 58 is set as a hollow structure. The outer side of the upper end of the piston rod 58 is in close contact with the inner wall of the guide shell 511. The guide shell 511 and the piston rod 58 correspond one-to-one with the compression spring 57. They slide in the guide shell 511 and convert the air pressure in the transmission chamber 52 into its own linear motion, which drives the blowing column 59 to move up and down. At the same time, it serves as an air transmission channel to transmit air to the blowing column 59.

[0031] As a further implementation of the above technical solution: the inner side of the air column 59 communicates with the inner side of the piston rod 58, the guide shell 511 and the transmission chamber 52. The air column 59 is located near the blade of the scissor-type cutter 4 to provide sliding guidance for the piston rod 58, ensuring the straightness and stability of the piston rod 58's movement. At the same time, it cooperates with the piston rod 58 to form an air transmission chamber, ensuring that the air pressure can effectively drive the piston rod 58 to move.

[0032] As a further implementation of the above technical solution: a drive mechanism 2 is fixedly connected to one side of the upper end of the control device 1, a positioning clamping device 3 is fixedly connected to the upper outer side of the control device 1, and a scissor-type blade 4 is provided on the inner side of the upper end of the control device 1. The outer side of the scissor-type blade 4 is slidably connected to the inner side of the support frame 51, providing an installation base for components such as the transmission chamber 52 and the guide tube 53, ensuring the accurate relative position of each component, and maintaining the stability of the overall structure of the cleaning device 5.

[0033] As a further implementation of the above technical solution: multiple air holes 510 are provided, and the air holes 510 are distributed in a circular array on the outside of the air column 59. The cross-sectional shape of the air holes 510 is trapezoidal, which increases the air coverage area and allows the airflow to act more evenly on the tool surface, effectively cleaning the debris in different positions. The trapezoidal cross-section design helps to optimize the airflow jet effect and enhance the air cleaning ability.

[0034] As a further implementation of the above technical solution: the vertical cross-section of the transmission chamber 52 is E-shaped, the transmission chamber 52 is located above the scissor-type blade 4, the corner of the transmission chamber 52 is set as arc, and the transmission chamber 52 is connected to the inner side of the guide tube 53 to provide an airflow channel for the air blowing column 59 to clean.

[0035] As a further implementation of the above technical solution: the guide tube 53 is provided with two ends, the inner wall of the guide tube 53 is in close contact with the outer side of the first piston 56, and the center points of the guide tube 53, the first piston 56 and the guide rod 55 are located on the same vertical line. When the scissor-type blade 4 moves, the compression and transmission control of air is realized through the sliding of the first piston 56, providing a power source for air blowing cleaning.

[0036] Workflow: After being connected to the power supply via an external wire, the operator places the diode to be cut in the designated position. The positioning and clamping device 3 accurately positions and clamps the diode according to the preset program to ensure that the diode does not shift during the cutting process. The control device 1 issues a command, and the drive mechanism 2 starts working to provide power to the scissor-type blade 4, causing it to move towards the diode pin. During the movement, the outer side of the scissor-type blade 4 slides against the inner side of the support frame 51. When the scissor-type blade 4 reaches the designated position, it cuts the diode pin to complete the pin cutting operation.

[0037] When the scissor-type blade 4 moves upward to prepare for the cutting action, the guide rod 55, which is fixedly connected to the upper end of the blade, moves upward accordingly. The guide rod 55 drives the first piston 56 to slide upward in the guide tube 53. At this time, the one-way valve 54 is passively opened by the compressed air, so that the compressed air is squeezed through the transmission chamber 52 to the inside of the guide shell 511 and the inside of the piston rod 58, and then blown outward through the air column 59 and the air hole 510 until the scissor-type blade 4 is ready to move downward to the diode pin. At the same time, the bottom of the air column 59 is in close contact with the upper end of the scissor-type blade 4, and the air is blown outward through the scissor-type blade. The upward movement of blade 4 causes the air column 59 and piston rod 58 to move upward, while simultaneously compressing the compression spring 57. At this time, the airflow blows away metal debris from the surface and surrounding area of ​​the scissor blade 4, preventing debris accumulation from affecting the normal operation of the blade. When the scissor blade 4 completes the cutting action and moves downward to reset, the guide rod 55 and the first piston 56 also move downward to reset. At this time, the one-way valve 54 closes, and under the elastic force of the compression spring 57, the piston rod 58 and air column 59 slide downward to reset. The lower end of the air column 59 remains in close contact with the upper end of the scissor blade 4, facilitating cleaning next time.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
