Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to a pin forming device. Background Technology

[0002] In the field of optical communication, optical devices are the core components, and their performance and assembly precision determine the overall system's operational quality. The pins of optical devices, as the connection interfaces with external circuits, usually need to be shaped at specific angles and lengths to meet the spatial layout requirements of different installation scenarios. Currently, most pin forming fixtures are operated manually, with one forming size corresponding to one manual fixture, which faces problems such as low production efficiency and inconsistent bending angles.

[0003] Therefore, designing a pin forming device with a high degree of automation and high dimensional accuracy is of great importance to those skilled in the art. Utility Model Content

[0004] This utility model provides a pin forming device with a high degree of automation and high forming dimensional accuracy to solve the problems of low production efficiency and inconsistent bending angles in the prior art.

[0005] This utility model discloses a pin forming device for pin forming of optical devices, the solution of which includes: Base; A clamping assembly is provided on the base for securing the optical device and its root pins; A bending assembly is disposed on the base and located on one side of the clamping assembly. The bending assembly includes a first driving member, a pushing member, and a limiting plate. An arc-shaped groove is formed on the limiting plate. A limiting member is provided on the side of the limiting plate near the clamping assembly of the arc-shaped groove. One end of the pushing member is connected to the first driving member, and the other end of the pushing member passes through the arc-shaped groove and is partially exposed above the limiting plate. When the optical device is placed in the clamping assembly, the pins of the optical device can be confined between the limiting member and the pushing member. The first driving member can drive the pushing member to rotate, so as to push the pins of the optical device to bend around the limiting member.

[0006] Optionally, the clamping assembly includes a fixing member, a second driving member, and a clamping member. The fixing member is provided with a limiting groove for placing an optical device. The clamping member is disposed above the fixing member and connected to the second driving member. The second driving member can drive the clamping member to move toward the fixing member to clamp the optical device in the limiting groove.

[0007] Optionally, the clamping member is provided with a first clamping part for clamping the optical device and a second clamping part for clamping the root pin of the optical device on the side facing the fixing member.

[0008] Optionally, the limiting groove is a V-shaped groove or an arc-shaped groove.

[0009] Optionally, the limiting member is a limiting post, and the height of the limiting post is greater than the diameter of the pin of the optical device.

[0010] Optionally, the pushing member is a pushing rod, and the height of the pushing rod protruding above the limiting plate is greater than or equal to the height of the limiting post.

[0011] Optionally, the assembly also includes a shearing component disposed on one side of the bending assembly for shearing the bent pin to the desired length.

[0012] Optionally, the cutting assembly includes pliers, a third drive unit, and a slider. A slide rail is provided on the base, and the slider is disposed on the slide rail.

[0013] Optionally, the cutting pliers are provided with a protective cover.

[0014] Optionally, the base is also provided with a waste tray for collecting the cut-off excess pins.

[0015] The beneficial effects of the pin forming device provided in this embodiment of the utility model are as follows: the clamping component firmly and accurately positions the optical device and its root pin, avoiding displacement or shaking of the optical device during processing. During the bending process, the arc groove of the limiting plate limits the movement trajectory of the pushing component, and the limiting component acts as a fixed fulcrum to make the pin bend precisely around it. The three work together to form a high-precision bending system of "positioning-guiding-fulcrum", which effectively avoids the problems of angle deviation and pin deformation when bending manually or with simple devices. It greatly improves the accuracy of the pin bending angle and the consistency of mass production. Moreover, the optical device does not need to be transferred between different devices to complete the entire process from positioning to forming, saving the time cost of manual transfer and repositioning, effectively shortening the pin processing cycle of a single optical device, and meeting the mass production needs of modern production lines.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 5 As shown, this utility model provides a specific embodiment of a pin forming device.

[0020] A pin forming apparatus for forming the pins of an optical device a, reference. Figures 1 to 6 The pin forming device includes a base 100, a clamping component 200, and a bending component 300. The clamping component 200 is disposed on the base 100 for fixing the optical device a and its root pin a1. The bending component 300 is disposed on the base 100 and located on one side of the clamping component 200 for bending the tail pin of the optical device a.

[0021] The bending assembly 300 includes a first drive 310, a pusher 320, and a limiting plate 330. The limiting plate 330 has an arc-shaped groove 331. A limiting member 332 is provided on the side of the limiting plate 330 near the pressing assembly 200 of the arc-shaped groove 331. One end of the pusher 320 is connected to the first drive 310, and the other end of the pusher 320 passes through the arc-shaped groove 331 and is partially exposed above the limiting plate 330. When the optical device a is placed in the pressing assembly 200, the pins of the optical device a can be limited between the limiting member 332 and the pusher 320. The drive can drive the pusher 320 to rotate, so as to push the pins of the optical device a to bend around the limiting member 332.

[0022] Specifically, refer to Figures 1 to 6 The base 100 serves as the mounting foundation and bearing platform for the entire pin forming device, providing stable mounting support for core components such as the clamping assembly 200 and the bending assembly 300. The clamping assembly 200 is mounted on the base 100 to securely fix the optical device a and its root pin a1. On the one hand, it can prevent the optical device a from shifting, shaking, or deflecting during the pin bending process, ensuring the stability of the reference position during pin bending and providing a prerequisite guarantee for subsequent bending accuracy. On the other hand, it can prevent the root of the pin from breaking during the pin bending process, thereby ensuring product quality and improving the product yield.

[0023] The bending assembly 300, as the core component for realizing the bending of the tube pin, provides power support for the rotation of the pusher 320 through the first drive 310. One end of the pusher 320 is connected to the first drive 310, and the other end passes through the arc groove 331 on the limiting part and is exposed above the limiting plate 330. The pusher 320 acts directly on the tube pin. Under the drive of the first drive 310, the pusher 320 can rotate along the trajectory of the arc groove 331, thereby pushing the tube pin to complete the bending action around the limiting part 332.

[0024] The entire pin forming device utilizes a grid structure that works in tandem to achieve precise bending of the pins. The specific working process is as follows: First, the optical device a with the pin to be formed is placed on the clamping component 200 on the base 100. The clamping component 200 is activated and firmly fixes the main body of the optical device a and the root pin a1, completing the positioning preparation before the pin is bent. At this time, the pin to be bent of the optical device a naturally extends to one side of the bending component 300 and is limited between the limiting member 332 and the pushing member 320 on the limiting plate 330, forming a "fulcrum-force point" cooperation relationship. Then, the first drive 310 is activated, and the output power drives the pushing member 320 to rotate along the arc groove 331 on the limiting plate 330. During the rotation, the pushing member 320 applies a continuous and stable thrust to the pin. Since the root of the pin is fixed by the clamping component 200 and the part to be bent is blocked by the limiting member 332, under the thrust of the pushing member 320, the pin will strictly follow the limiting member 332 and complete the bending action according to the trajectory defined by the arc groove 331, and finally form a bent shape at a preset angle.

[0025] In this embodiment, a pin forming device is designed. The clamping component 200 firmly and accurately positions the optical device a and its root pin a1, preventing displacement or shaking of the optical device a during processing. During bending, the arc groove 331 of the limiting plate 330 limits the movement trajectory of the pushing component 320, and the limiting component 332 acts as a fixed fulcrum to allow the pin to bend precisely around it. The three work together to form a high-precision bending system of "positioning-guiding-fulcrum", which effectively avoids the angle deviation and pin deformation problems caused by manual bending or bending with simple devices, and greatly improves the accuracy of the pin bending angle and the consistency of mass production. Furthermore, this design integrates the three key processes of pin fixing, bending, and cutting into one, so that the optical device a can complete the entire process from positioning to forming without being transferred between different devices. This saves the time cost of manual transfer and repositioning, effectively shortens the pin processing cycle of a single optical device a, and can meet the mass production needs of modern production lines.

[0026] In one embodiment, reference Figures 1 to 3 The clamping assembly 200 includes a fixing member 210, a second driving member 220, and a clamping member 230. The fixing member 210 is provided with a limiting groove 211 for placing the optical device a. The clamping member 230 is disposed above the fixing member 210 and connected to the second driving member 220. The second driving member 220 can drive the clamping member 230 to move toward the fixing member 210 to clamp the optical device a in the limiting groove 211.

[0027] Specifically, refer to Figures 1 to 6The fixing member 210 serves as the support base for the optical device a. The limiting groove 211 on it can be a V-shaped groove or an arc-shaped groove 331 to match the outer contour of the optical device a. This provides initial positioning constraints for the optical device a, ensuring that it will not shift laterally when placed, and providing a precise reference position for subsequent pressing actions. The second driving member 220 is the power source for pressing, capable of outputting linear driving force to drive the pressing member 230 to move up and down. The smoothness of its power output ensures the uniformity of the pressing force, avoiding damage to the optical device a due to sudden pressure changes. The pressing member 230 is located above the fixing member 210 and connected to the second driving member 220. It is the pressing actuator that directly contacts the optical device a. Under the drive of the second driving member 220, the pressing member 230 can move towards the fixing member 210 until it is tightly fitted with the optical device a in the limiting groove 211. Through the cooperation with the fixing member 210, a clamping force is formed, and the optical device a is firmly fixed in the limiting groove 211.

[0028] In one embodiment, reference Figures 1 to 6 The clamping member 230 is provided with a first clamping part 231 for clamping the optical device a and a second clamping part 232 for clamping the root pin a1 of the optical device a on the side facing the fixing member 210.

[0029] Specifically, refer to Figures 1 to 6 The first clamping part 231 is adapted to the outer contour of the main body of the optical device a, which can form a large-area, close-fitting clamping contact. This not only avoids damage to the main body of the optical device a due to excessive local pressure, but also ensures that the main body of the optical device a does not shift or rotate during the bending process. This provides a stable and accurate fixed reference for the entire pin bending process, reducing bending deviation caused by the displacement of the main body from the source.

[0030] The second clamping part 232 is specifically designed to act on the root pin a1 of the optical device a. By directly clamping the root of the pin, it can effectively prevent the pin root from breaking during bending. Since the bending force of the pin will be transmitted to the root, the second clamping part 232 can provide reliable end constraint for the pin, making the force state of the pin more stable when bending around the limiting member 332, and further improving the accuracy of the bending angle. Especially for the optical device a with weak connection strength between the pin and the main body, it can reduce the risk of deformation of the connection part.

[0031] Reference in one embodiment Figures 1 to 6 The limiting component 332 is a limiting post, and the pushing component 320 is a pushing rod. The height of the limiting post is greater than the diameter of the pin of the optical device a. The height of the pushing rod exposed above the limiting plate 330 is greater than or equal to the height of the limiting post. By setting this height, the pin of the optical device a can be stably pressed between the fixing block and the pressing block, thereby improving the stability of the bending operation and the accuracy of the bent pin.

[0032] In one embodiment, reference Figures 1 to 4 The pin forming device also includes a shearing assembly 400, which is disposed on one side of the bending assembly 300 for cutting the bent pin to the required length. The shearing assembly 400 includes a shearing clamp 410, a third drive member 420, and a slider 430. A slide rail 110 is provided on the base 100, and the slider 430 is disposed on the slide rail 110. The shearing clamp 410 and the third drive member 420 are both connected to the slider 430. The third drive member 420 can drive the slider 430 to move along the slide rail 110, so as to move the shearing clamp 410 closer to or away from the bent pin.

[0033] Specifically, the shearing pliers 410, as the core component directly performing pin shearing, has a blade design adapted to the pin diameter, enabling it to quickly and accurately cut the bent pin, ensuring a smooth, burr-free cut surface and preventing the assembly accuracy and electrical signal transmission performance of subsequent optical devices a from being affected by shearing quality issues. The third drive unit 420 provides the power source for the movement of the shearing assembly 400. By precisely controlling the output force and stroke, it drives the slider 430 to move stably along the slide rail. The stability of its power output directly determines the positioning accuracy of the shearing pliers 410, ensuring that the shearing pliers 410 can accurately reach the preset shearing position and achieve precise control of the pin length. The slide rail 110 is fixed on the base 100, providing rigid guidance for the slider 430 and strictly limiting the movement trajectory of the slider 430 (usually in a straight line), ensuring that the shearing pliers 410 will not deviate during movement. The slider 430, as a load-bearing structure, integrates the shearing pliers 410 and the third drive unit 420 into one unit. Under the action of the driving force, it drives the shearing pliers 410 to smoothly approach or move away from the bent pin, achieving flexible adjustment of the shearing position.

[0034] The precise guidance of the shearing clamp 410 is achieved through the cooperation of the slide rail and the slider 430. Combined with the precise power control of the third drive component 420, the shearing position error can be controlled within a very small range, ensuring the high consistency of the shearing length of the tubes in mass production. This avoids dimensional deviations caused by manual shearing or step-by-step processing. The relative position of the shearing clamp 410 and the tubes can be flexibly adjusted by the third drive component 420 driving the slider 430 to adapt to the shearing requirements of different lengths. The mechanically driven shearing action avoids the uncertainty of manual operation. The stable movement of the shearing clamp 410 under the constraint of the slide rail can prevent the tubes from bouncing or flying off due to uneven force during shearing, reducing safety hazards. In addition, automated shearing reduces direct contact between humans and equipment, further improving production safety.

[0035] In one embodiment, reference Figures 1 to 6 The shearing pliers 410 is equipped with a protective cover 411 to prevent accidental injury to the operator.

[0036] In one embodiment, reference Figures 1 to 6 The base 100 is also equipped with a waste tray 500 to collect excess tubes that have been cut off. The waste tray 500 can collect the tube waste generated during cutting, preventing small metal waste from falling into equipment gaps, slide rails or work surfaces, reducing the risk of equipment jamming due to waste accumulation, and reducing the frequency and difficulty of manual cleaning, thus maintaining the cleanliness and orderliness of the production area.
