Description

Technical Field

[0001] This utility model relates to the field of lead cutting machine technology, and in particular to a buzzer lead cutting machine. Background Technology

[0002] A lead cutting machine is an automated device used to cut the leads of electronic components. It is widely used in the production process of electronic components such as capacitors, resistors, and inductors. In capacitor manufacturing, the lead cutting machine can efficiently and accurately remove excess lead length, ensuring that the component meets the standard size and facilitating subsequent installation and soldering. Announcement No. CN209969457U discloses a rapid lead cutting device for buzzers, relating to the field of lead cutting machine technology. It includes a worktable, on which a positioning mechanism, a driving mechanism, and an auxiliary positioning mechanism are provided. The positioning mechanism includes a vertical plate and a positioning plate horizontally arranged on the vertical plate. The positioning plate is provided with several positioning grooves, each including a body groove. The bottom of the body groove has a lead through hole, the length of which is the same as the standard length of the buzzer. This invention inserts the pins of the buzzer to be cut into the positioning through holes on the positioning plate. Then, a drive cylinder drives the blade plate to move along the lower surface of the positioning plate, thereby cutting off the excess pins. The length of the positioning through hole is equal to the standard length of the buzzer pin, and the buzzer pin is fixed to ensure cutting accuracy. At the same time, by setting a safety sensor on the door, cutting operations are avoided when the door is not closed, ensuring the safety of the workers. This invention can quickly cut off the pins while ensuring cutting accuracy by setting positioning through holes and several positioning grooves. However, it cannot flexibly adapt to buzzers of different specifications or buzzer pins of different lengths and thicknesses, and is prone to problems such as unstable positioning and cutting size deviation, which affects cutting accuracy and requires improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a buzzer pin cutting machine, including a base, a cutting seat fixedly installed on the upper surface of the base, a screw block and a slide block fixedly installed on the surface of the cutting seat, a pusher motor fixedly installed on the surface of the cutting seat, a pusher screw fixedly installed at the output end of the pusher motor, a pusher plate threadedly connected to the surface of the pusher screw, a pusher slide rod fixedly installed inside the slide block, a cutting motor and a cutting slide rod fixedly installed on the surface of the cutting seat, a cutting screw fixedly installed at the output end of the cutting motor, a cutting seat threadedly connected to the surface of the cutting screw, a cylinder fixedly installed on the surface of the cutting seat, a cutter seat fixedly installed at the output end of the cylinder, a cutter fixedly installed on the surface of the cutter seat, a support plate motor fixedly installed on the surface of the cutting seat, a support plate screw fixedly installed at the output end of the support plate motor, a support plate slide rod fixedly installed inside the cutting seat, and a support plate threadedly connected to the surface of the support plate screw.

[0005] Preferably, the lengths of the pusher screw and the pusher slide are the same and symmetrically distributed on both sides of the base, and the interior of the pusher plate and the surface of the pusher slide are slidably connected. This design allows the pusher plate to remain stable during movement, preventing tilting or jamming due to uneven force. The pusher screw provides the driving force, while the pusher slide acts as a guide and support. Their cooperation makes the pusher plate's movement smoother and more stable, ensuring accurate positioning of the buzzer pin, which is beneficial for subsequent cutting processes. It also reduces wear during equipment operation and extends the service life of components.

[0006] Preferably, the interior of the cutting seat and the surface of the cutting slide are slidably connected, and the surface of the cutter can be brought into contact with the surface of the support plate by the extension and retraction of the cylinder. This allows the cutting seat to move stably under the guidance of the cutting slide, ensuring accurate cutting position. The cylinder drives the cutter to extend and retract, enabling the cutter to precisely contact the surface of the support plate, ensuring uniform cutting force on the buzzer pins, avoiding incomplete or over-cutting, improving cutting quality, and making the cutting action more flexible and controllable, adapting to the cutting needs of buzzer pins of different specifications.

[0007] Preferably, the lengths of the cutting screw and the cutting slide are the same, as are the lengths of the support plate screw and the support plate slide. The interior of the support plate and the surface of the support plate slide are slidably connected. Here, the identical lengths of the cutting screw and the cutting slide ensure balanced force distribution during movement of the cutting seat, preventing trajectory deviation due to length differences. The identical lengths of the support plate screw and the support plate slide, along with the slidable connection between the support plate and the support plate slide, allow for smoother movement of the support plate, preventing jamming or tilting. This ensures precise coordination between cutting and supporting actions, reduces unnecessary wear on components during movement, enhances the overall stability and reliability of the equipment, and improves the consistency and pass rate of buzzer pin cutting.

[0008] Preferably, a limit motor is fixedly mounted on the surface of the base, a limit screw is fixedly mounted on the output end of the limit motor, a limit slide rod is fixedly mounted inside the base, a limit plate is threadedly connected to the surface of the limit screw, a rotating rod is fixedly mounted inside the limit plate, and a rotating roller is rotatably connected to the surface of the rotating rod. This design effectively prevents narrow cutting pieces from shifting when pushed by the push plate. The limit screw and limit slide rod work together to drive the limit plate to move stably, facilitating adjustment of the limit distance according to the width of the cutting piece. The rotating roller is connected to the limit plate via the rotating rod and rotates with the cutting piece when in contact with it, thus providing both a limit and blocking function without hindering the normal pushing of the cutting piece due to friction. This ensures that the cutting piece always moves along the correct path, guaranteeing precise subsequent cutting.

[0009] Preferably, the limiting screw is a bidirectional threaded rod, and the length of the limiting screw is the same as the length of the limiting slide bar. Multiple rotating rollers are evenly distributed on the limiting plate. This allows the limiting plates on both sides to move synchronously in opposite directions under the same drive, quickly and accurately adjusting the limiting distance to adapt to the limiting requirements of cutting parts of different widths. The fact that the limiting screw and the limiting slide bar are of the same length ensures the stability of the limiting plate during movement, preventing tilting due to length differences and ensuring the limiting effect. Multiple evenly distributed rotating rollers can limit the cutting part from multiple points, further enhancing the constraint on narrow cutting parts and preventing them from tipping over or shifting during pushing. Simultaneously, the rotational characteristics reduce frictional damage to the surface of the cutting part, ensuring its integrity.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a push screw, a cutting screw, a cylinder, a support plate screw, and a support plate, the push screw drives the push plate to move smoothly along the push slide rod, pushing the buzzer pin to the cutting position. The cutting screw drives the cutting seat to slide on the cutting slide rod, adjusting the lateral position of the cutter. The cylinder drives the cutter seat to move up and down, realizing the lifting and lowering of the cutter. Together with the support plate, the pin cutting is completed. The support plate screw drives the support plate to slide on the support plate slide rod, adjusting the support position according to the pin height, providing stable support for cutting, making the pin cutting process precise and controllable, adapting to the pin cutting needs of buzzers of different specifications, improving the versatility and pin cutting efficiency of the equipment, and providing a strong guarantee for the large-scale production of buzzers.

[0012] 2. In this utility model, by setting a limiting screw, a limiting slide bar, a limiting plate, a rotating rod, and rotating rollers, the limiting screw can drive the limiting plates on both sides to move synchronously in the opposite direction along the limiting slide bar, quickly adapting to pins of different widths and ensuring accurate limiting distance. The limiting slide bar provides stable guidance for the movement of the limiting plate, preventing it from deviating or tilting. The multiple rotating rollers on the limiting plate can rotate flexibly through the rotating rod. When in contact with the pin, they can effectively block it from both sides, preventing narrow pins from tipping over or deviating when pushed by the push plate. They can also rotate with the pin, reducing contact friction damage to the pin surface. The coordinated operation ensures the stability of the pin on the conveying path and also takes into account the smoothness of the conveying process, laying the foundation for the accurate execution of subsequent cutting processes and improving the equipment's adaptability to pins of different specifications and the overall operation quality.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-4This utility model provides a technical solution: a buzzer pin cutting machine, including a base 1, which serves as the basic support component of the entire device, providing an installation platform for all upper components such as the cutting seat 2 and the limit motor 20, ensuring the stability of the overall structure of the device, and enabling each component to maintain a relatively fixed positional relationship during operation. The cutting seat 2 is fixedly installed on the upper surface of the base 1, and a screw block 3 and a sliding block 7 are fixedly installed on the surface of the cutting seat 2. A pusher motor 4 is fixedly installed on the surface of the cutting seat 2, serving as the power source for the pusher mechanism. The rotation of the output end drives the pusher screw 5 to rotate, providing driving force for the movement of the pusher plate 6 and controlling the movement state of the pusher plate 6. The output end of the pusher motor 4 is fixedly installed with the pusher screw 5, and the surface of the pusher screw 5 has threads. A push plate 6 is connected to a slide block 7, and a pusher slide rod 8 is fixedly installed inside the slide block 7. The length of the pusher screw 5 is the same as the length of the pusher slide rod 8 and they are symmetrically distributed on both sides of the base 1. The push plate 6 and the surface of the pusher slide rod 8 are slidably connected. This allows the push plate 6 to remain stable during movement and avoid tilting or jamming due to uneven force. The pusher screw 5 provides driving force, while the pusher slide rod 8 plays a guiding and supporting role. The cooperation between the two makes the movement of the push plate 6 more stable and smooth, ensuring accurate pushing position of the buzzer pin, which is conducive to the smooth progress of subsequent cutting processes. At the same time, it can also reduce wear during equipment operation and extend the service life of components. The surface of the cutting foot seat 2 is fixedly installed with a cutting motor 9 and a cutting slide rod 11. A cutting screw 10 is fixedly mounted on the output end of motor 9. A cutting seat 12 is threadedly connected to the surface of the cutting screw 10. A cylinder 13 is fixedly mounted on the surface of the cutting seat 12. A cutter seat 14 is fixedly mounted on the output end of the cylinder 13. A cutter 15 is fixedly mounted on the surface of the cutter seat 14. The interior of the cutting seat 12 and the surface of the cutting slide rod 11 are slidably connected. The surface of the cutter 15 can be brought into contact with the surface of the support plate 19 by the extension and retraction of the cylinder 13. Here, the cutting seat 12 can move stably under the guidance of the cutting slide rod 11, ensuring the accuracy of the cutting position. The cylinder 13 drives the cutter 15 to extend and retract, so that the cutter 15 can accurately fit the surface of the support plate 19, ensuring uniform cutting force on the buzzer pin and avoiding incomplete or excessive cutting. To improve cutting quality and make the cutting action more flexible and controllable, adapting to the cutting needs of buzzer pins of different specifications, a support plate motor 16 is fixedly mounted on the surface of the cutting base 2. A support plate screw 17 is fixedly mounted on the output end of the support plate motor 16. A support plate slide rod 18 is fixedly mounted inside the cutting base 2. A support plate 19 is threadedly connected to the surface of the support plate screw 17. The length of the cutting screw 10 is the same as the length of the cutting slide rod 11. The lengths of the support plate screw 17 and the support plate slide rod 18 are the same. The interior of the support plate 19 and the surface of the support plate slide rod 18 are slidably connected. Here, the cutting screw 10 and the cutting slide rod 11 are the same length, which ensures that the cutting base 12 is subjected to balanced force when moving and will not deviate from the movement trajectory due to the difference in their lengths.The support plate screw 17 and the support plate slide rod 18 are of the same length, and the support plate 19 is slidably connected to the support plate slide rod 18. This allows the support plate 19 to move more smoothly, avoiding jamming or tilting, ensuring precise coordination between cutting and supporting actions, reducing unnecessary wear on components during movement, enhancing the overall stability and reliability of the equipment, and improving the consistency and pass rate of buzzer pin cutting.

[0024] Example 2

[0025] Please see Figure 5 A limit motor 20 is fixedly installed on the surface of the base 1, serving as the power source for the limit mechanism. The motor's output rotation drives the limit screw 21 to rotate, providing driving force for the movement of the limit plate 22 and controlling its position adjustment. The limit screw 21, with a bidirectional threaded rod design, is fixedly installed at the output end of the limit motor 20. Driven by the limit motor 20, it rotates, causing the limit plates 22 on both sides to move synchronously in opposite directions, thus adjusting the limit distance to accommodate the limit requirements of cut-to-length parts of different widths. A limit slide rod 23 is fixedly installed inside the base 1, which... The limiting plate 22 is slidably connected, providing guidance for its movement and restricting its direction of motion. This ensures the limiting plate 22 remains stable during adjustment and guarantees the limiting effect. The limiting screw 21 is threadedly connected to the limiting plate 22. A rotating rod 24 is fixedly installed inside the limiting plate 22, and a rotating roller 25 is rotatably connected to the surface of the rotating rod 24. This effectively prevents the narrow cutting piece from shifting when pushed by the push plate 6. The limiting screw 21 cooperates with the limiting slide rod 23 to drive the limiting plate 22 to move stably, facilitating the adjustment of the cutting piece. The width adjustment limit spacing is achieved, and the rotating roller 25 is connected to the limiting plate 22 via the rotating rod 24. When it comes into contact with the cutting part, it can rotate with it, which not only serves as a limit and block but also prevents the normal pushing of the cutting part due to friction, ensuring that the cutting part always moves along the correct path and providing a guarantee for subsequent precise cutting. The limiting screw 21 is a bidirectional threaded rod, and the length of the limiting screw 21 is the same as the length of the limiting slide rod 23. There are multiple rotating rollers 25 evenly distributed on the limiting plate 22. Here, the limiting plates 22 on both sides can achieve synchronous reverse movement under the same drive. The movement allows for quick and precise adjustment of the limiting distance to adapt to the limiting requirements of cut-out parts of different widths. The limiting screw 21 and the limiting slide bar 23 are of the same length, which ensures the stability of the limiting plate 22 during movement and prevents the limiting plate 22 from tilting due to the difference in length between the two, thus ensuring the limiting effect. Multiple evenly distributed rotating rollers 25 can limit the cut-out parts from multiple points, further enhancing the constraint on narrow cut-out parts and preventing them from tipping over or deviating during the pushing process. At the same time, the rotation characteristics can also reduce frictional damage to the surface of the cut-out parts, ensuring the integrity of the cut-out parts.

[0026] Working Principle: When dealing with buzzers of different specifications or buzzer pins of different lengths and thicknesses, and needing to quickly fix them to prevent unstable positioning, cutting size deviations, and other problems that could affect cutting accuracy, the limit motor 20 drives the limit screw 21 to rotate, causing the limit plate 22 to move synchronously along the limit slide 23, adjusting to the limit spacing that matches the pin width. The rotating roller 25 rotates with the pin, constraining the pin to prevent deviation. The support plate motor 16 starts, driving the support plate screw 17 to move the support plate 19 along the support plate slide 18 to the support position corresponding to the pin height. The pusher motor 4 drives the pusher screw 5 to rotate, causing the pusher plate 6 to smoothly push the pin to the cutting area along the pusher slide 8. The cutting motor 9 drives the cutting screw 10 to adjust the position of the cutting seat 12. The cylinder 13 drives the cutter 15 to descend and cooperate with the support plate 19 to complete the cutting. The combination of screws and slides ensures smooth movement. The bidirectional screw and multi-rotating roller 25 design improves adaptability, enabling rapid and stable positioning and high-precision cutting of buzzer pins of different specifications.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
