Description

Technical Field

[0001] This utility model relates to the field of terminal processing and treatment, and more specifically, it relates to a terminal bending device. Background Technology

[0002] In the precision manufacturing of electronic components such as connectors and circuit boards, it is often necessary to cut (remove material) or bend multiple parallel terminals formed on the component body. Although traditional processes pursue efficient and precise operation, existing technical solutions have significant bottlenecks: step-by-step independent processing is not only inefficient, but multiple clamping can easily lead to cumulative positioning errors, which seriously affect product quality; although composite molds can form in one step, due to their rigid structure and insufficient flexibility, they are difficult to adapt to the needs of rapid changeover for small batches and multiple varieties.

[0003] Furthermore, when simultaneously removing or bending multiple terminals, existing simple mechanisms struggle to guarantee product consistency and yield. Therefore, there is an urgent need in this field for a novel terminal bending mechanism that can fundamentally overcome efficiency challenges and meet the high-efficiency and highly adaptable production requirements of modern electronics manufacturing.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0017] A terminal bending device is mainly used to cut or bend multiple parallel terminals on electronic components such as connectors.

[0018] The core of this device includes a base 1, a scraper 2, and a mounting base 3. The base 1 serves as the fundamental support for the entire device, and its top surface is machined with a mounting groove 12. The bottom of the mounting base 3 has a matching protrusion or slider structure, allowing it to slide and engage within the mounting groove 12 of the base 1. This design allows the mounting base 3 to be easily installed onto or removed from the base 1, facilitating loading and unloading, while ensuring the initial horizontal position accuracy of the mounting base 3 on the base 1. The mounting base 3 is used to support and secure the terminals to be processed. The scraper 2 is connected to a drive unit via a rotating shaft. This drive unit can be a rotary cylinder or a servo motor, which is fixedly mounted on the side of the base 1 or on a separate bracket, enabling precise control of the scraper 2's rotation. The base 1 itself has a built-in or connected flipping drive mechanism, which drives the mounting base 3, along with the terminals on it, to flip at a specific angle within the mounting groove 12 of the base 1.

[0019] During operation, the component carrying multiple terminals is first placed on and secured to the mounting base 3. Then, the mounting base 3 rotates, activating the drive mechanism, which rotates the scraper 2 towards the pin tip of the terminal. The cutting edge or working surface of the scraper 2 contacts the terminal pin, performing a cutting or bending operation. Multiple processes can be completed in a single setup, greatly improving processing accuracy and efficiency.

[0020] In a preferred embodiment, the top surface of the mounting base 3 has several parallel slots 31. The size of each slot 31 matches the root of the terminal or the body 4, and is used to accommodate and fix one or more terminals. One or both ends of the slot 31 are provided with a limiting part 6, which can be a protruding stop, to restrict the movement of the terminal in the vertical direction, prevent the terminal from accidentally dislodging from the slot 31 during processing, and ensure the stability of processing.

[0021] To achieve flexible clamping of the terminal, in another improved embodiment, a mounting hole is provided on one side wall or bottom surface of the slot 31. A limiting spring 34 and a limiting ball 33 are sequentially arranged inside the hole. One end of the limiting spring 34 is fixed to the bottom of the hole, and the other end abuts against the limiting ball 33, causing a portion of the spherical surface of the limiting ball 33 to protrude from the inner wall of the slot 31. When the terminal is inserted into the slot 31, it squeezes the limiting ball 33 and compresses the limiting spring 34. The spring force continuously applies a pressure pointing towards the terminal through the limiting ball 33, thereby forming a flexible clamping force. This structure can effectively accommodate small tolerances in terminal dimensions and provide stable friction to prevent the terminal from loosening, while avoiding surface damage that may be caused by rigid clamping.

[0022] The base 1 can be specifically divided into a connecting part fixed to the equipment base and a rotating part 13 rotatably connected to the connecting part via bearings. A fixing groove 12 is provided on the top surface of the rotating part 13. A flipping drive mechanism acts on the rotating part 13, driving it to flip relative to the connecting part. To precisely control the flipping angle, a limit block is provided on the connecting part, and a corresponding protrusion on the rotating part 13 is provided that can be blocked by the limit block. When the rotating part 13 flips to a predetermined angle, its protrusion contacts the limit block, thus being reliably limited, preventing overshoot, and ensuring the accuracy of each flipping angle.

[0023] The specific structure of the scraper 2 varies depending on its function. The scraper 2 used for terminal cutting includes a body 4 and a scraping part 5. The end edge of the scraping part 5 is machined into an inclined scraping surface. This inclined scraping surface forms an acute angle with the axis of the terminal pin, so that the scraper 2 can remove excess pins by cutting or scraping during rotation, thereby obtaining a smooth cut and reducing burrs.

[0024] The scraper 2 used for terminal bending includes a body 4 and a bending section 51. The bending section 51 is connected to the end of the body 4, and its working surface is constructed as a smooth S-shaped curved surface. When the scraper 2 rotates, the S-shaped bending surface gradually and smoothly contacts the terminal pin and applies pressure, causing the pin to undergo plastic deformation along the curved surface, eventually bending it into a predetermined arc or a specific angle. This progressive bending process can effectively avoid stress concentration caused by right-angle bending, reduce the risk of terminal cracking or internal damage, and achieve higher forming quality.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
