Description

Technical Field

[0001] This utility model relates to the field of pin forming technology, and more specifically, to a device for pin forming of a butterfly laser. Background Technology

[0002] Traditional lead forming methods often use tools such as flat-nose pliers or tweezers to hold the device body and bend the leads to form the lead. This method easily creates indentations or deformations on the device body or leads, and lacks suitable measuring tools, making it difficult to ensure that the distance from the bending start point to the device body's terminal seal, the lead bending radius, and the component mounting height meet process standards. Furthermore, because leads are relatively soft and elastic, traditional methods struggle to ensure coplanarity after lead forming, making it difficult to match the formed leads with the printed circuit board mounting pads, and leading to poor solder joint reliability.

[0003] With the development of the optoelectronic communication industry, the demand for butterfly lasers is constantly increasing. Manual bending and forming is not only labor-intensive and slow, but also has poor forming accuracy. In the prior art, application CN109103132B discloses a pin bending and forming mechanism, but its structure is complex and difficult to meet the requirements of large-scale production, assembly and welding processes. Therefore, there is a need for a pin forming device with a simple structure that can improve production efficiency and forming accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a device for forming the pins of a butterfly laser, so as to solve the problems of low pin forming efficiency and easy damage in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] An apparatus for forming the pins of a butterfly laser includes a support base, a mounting plate on the support base, a pressing mechanism on the mounting plate, a guide plate connected to the pressing mechanism, two forming blocks at the bottom of the guide plate, a compression spring between the forming blocks, and a pressure block at the bottom of the compression spring; a limiting plate on the support base, a limiting groove on the limiting plate, and support blocks on both sides of the limiting groove; the support blocks and the pressure blocks cooperate with each other.

[0007] Furthermore, the pressing mechanism includes a mounting base and a pressing wrench; the pressing wrench is hinged to the mounting base; a connecting rod is hinged to the pressing wrench, and the bottom end of the connecting rod is connected to a guide plate.

[0008] Furthermore, the mounting base is provided with a guide hoop; the connecting rod passes through the guide hoop and connects to the guide plate, and the guide hoop and the connecting rod are in sliding engagement.

[0009] Furthermore, the support base is provided with a plug screw, and the guide plate is provided with a linear bearing; the guide plate is slidably connected to the plug screw through the linear bearing.

[0010] Furthermore, the number of the stop screws is two; the two stop screws are symmetrically arranged on both sides of the support base.

[0011] Furthermore, the bottom of both sides of the pressure block is provided with a lower edge, which cooperates with the support block.

[0012] Furthermore, the bottom inner sides of the two molded blocks are chamfered.

[0013] Furthermore, the outer side of the support block is chamfered.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model's pressing wrench forms a lever through a hinge. The operator only needs to apply a small force to the end of the wrench to amplify the force through the lever principle, driving the connecting rod and the entire guide plate and molding block assembly to press down, reducing the operator's labor intensity. Two symmetrically arranged plug screws and linear bearings provide balanced and stable guiding support, ensuring a smooth and jam-free pressing process, further improving the accuracy of movement and the durability of the device. The chamfered design on the inner side of the bottom of the molding block guides and transitions when the pin begins to bend, effectively preventing sharp edges from scratching or damaging the fragile laser pin, reducing stress concentration points, lowering the risk of pin breakage during bending, and effectively improving the yield rate of butterfly laser pin molding.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: An apparatus for forming the pins of a butterfly laser, such as... Figures 1-3 As shown, the device includes a support base 1, which provides the main frame and support for the entire device. A mounting plate 2 is mounted on the support base 1, and a pressing mechanism is mounted on the mounting plate 2. This mechanism serves as a power source and can be manually operated to drive the connected guide plate 5 to move up and down. The pressing mechanism is connected to the guide plate 5, and two forming blocks 11 are located at the bottom of the guide plate 5. A compression spring 6 is located between the forming blocks 11, and a pressure block 7 is located at the bottom of the compression spring 6. A guide pin passes through the spring, providing a certain clamping force to the pressure block 7 when the guide plate 5 moves downward. The pressure block 7 moves vertically up and down with the guide plate 5 to fix the inner pins of the butterfly laser 12. A limiting plate 8 is mounted on the support base 1 for positioning the butterfly laser 12. The limiting plate 8 has a limiting groove, and support blocks 13 are located on both sides of the limiting groove. The support blocks 13 and the pressure blocks 7 cooperate to complete the pin forming action.

[0023] Example 2: An apparatus for forming the pins of a butterfly laser, wherein the pressing mechanism includes a mounting base and a pressing wrench 9; the pressing wrench 9 is hinged to the mounting base; a connecting rod is hinged to the pressing wrench 9, and the bottom end of the connecting rod is connected to a guide plate 5.

[0024] The mounting base is provided with a guide hoop 10; the connecting rod passes through the guide hoop 10 and connects to the guide plate 5, and the guide hoop 10 and the connecting rod slide together.

[0025] The support base 1 is equipped with a stop screw 3, and the guide plate 5 is equipped with a linear bearing 4. The guide plate 5 is slidably connected to the stop screw 3 via the linear bearing 4, allowing the guide plate 5 to move vertically up and down. The cooperation between the stop screw 3 and the linear bearing 4, as well as the presence of the guide clamp 10, provides high-precision vertical guidance for the downward pressing movement. This ensures that the movement trajectory of the forming block 11 and the pressure block 7 is strictly vertical, preventing deviation, and thus ensuring that all pins are bent into completely consistent angles and shapes.

[0026] The number of stop screws 3 is two; the two stop screws 3 are symmetrically arranged on both sides of the support base 1.

[0027] The bottom of both sides of the pressure block 7 is provided with a lower edge 14, which cooperates with the support block 13.

[0028] The bottom inner sides of the two molding blocks 11 are chamfered. The outer side of the support block 13 is chamfered.

[0029] Everything else is the same as in Example 1.

[0030] The butterfly laser 12 is positioned on the limiting plate 8, centered horizontally and with its rear mounting corner against the inner side of the limiting plate 8 as a reference, ensuring accurate positioning. After positioning, the lowering wrench 9 is manually operated, causing the connecting rod on the lowering wrench 9 to move downwards. During this movement, the guide screw 3 and the linear bearing 4 work together to ensure no deviation occurs during displacement. The guide plate 5 moves downwards, causing the connected compression spring 6 and pressure block 7 to move downwards. The pressure block 7 first contacts the inner pin of the butterfly laser 12. At this time, the lowering wrench 9 causes the connecting rod to continue moving downwards, compressing the compression spring 6 and applying force to the pressure block 7. The pressure block 7 stops moving after applying a certain force to the inner pin of the butterfly laser 12. The guide plate 5 continues to press down to the bottom. The lowering wrench 9 is then operated again to move the telescopic rod upwards to the initial position. The butterfly laser 12 is then removed, and the pin forming of the butterfly laser 12 is complete.

[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
