This places extremely stringent requirements on the stability of the welded parts during the welding process.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing stabilization structures for electronic component welding typically lack dynamic clamping force adjustment mechanisms, making it difficult to adjust the clamping force in real time according to different component materials and sizes. This can easily lead to situations where the clamping is too tight, damaging fragile components, or too loose, causing the weldment to shift, thus affecting welding accuracy. Furthermore, existing stabilization structures for electronic component welding typically lack multi-coordinated vibration reduction designs, making it difficult to cope with multiple vibrations generated during the welding process, which affects the positional stability of the solder joint.

[0004] To address this, a stable structure for welding electronic components is proposed. Utility Model Content

This can easily lead to situations where the clamping is too tight, damaging fragile components, or too loose, causing the weldment to shift, affecting the accuracy of welding. Moreover, existing stable structures for welding electronic components usually lack multiple coordinated vibration reduction designs, making it difficult to cope with the multiple vibrations generated during the welding process, which affects the positional stability of the solder joint.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A stable structure for welding electronic components includes a welding platform base 1. Adaptive clamping components 4 are provided on both sides of the welding platform base 1, and a composite shock-absorbing component 5 is provided at the bottom of the welding platform base 1. The adaptive clamping components 4 include support plates 401 fixedly connected to both sides of the welding platform base 1. A drive motor 402 is fixedly connected to the outer side of the support plates 401. A drive screw 403 is fixedly connected to the output end of the drive motor 402. A moving block 404 is threadedly connected to the outer side of the drive screw 403. An adjusting cylinder 405 is fixedly connected to the top of the moving block 404. A clamping frame 406 is fixedly connected to the output end of the adjusting cylinder 405. An elastic air cushion 407 is provided inside the clamping frame 406. A pressure sensor 408 is provided on the top of the clamping frame 406. A high-temperature resistant clamping plate 409 is fixedly connected to the inner side of the elastic air cushion 407.

[0026] In this embodiment: by starting the drive motor 402, its output end drives the drive screw 403 to rotate, causing the moving block 404 on the drive screw 403 to move horizontally along the screw and adjust to the clamping position corresponding to the workpiece. Then, the adjusting cylinder 405 extends, pushing the clamping frame 406 closer to the workpiece. The pressure sensor 408 on the top of the clamping frame 406 starts monitoring the pressure. At the same time, the high-pressure air pump 2 on the outside of the clamping frame 406 supplies air to the elastic air cushion 407. The elastic air cushion 407 expands and pushes the high-temperature resistant clamping plate 409 to fit against the workpiece. The pressure sensor 408 transmits the pressure data to the regulating valve 3. The regulating valve 3 controls the air supply to maintain a suitable clamping force. Finally, the high-temperature resistant clamping plate 409 stably fixes the workpiece to avoid displacement during welding.

[0027] Specifically, such as Figure 3 As shown, the composite damping component 5 includes a base 501 fixedly connected to the bottom of the welding platform base 1, and a fixing seat 502 fixedly connected to the top of the base 501.

[0028] Specifically, such as Figure 3 As shown, a limiting frame 503 is fixedly connected to the top of the fixed base 502, a connecting spring 504 is fixedly connected inside the limiting frame 503, a transmission seat 505 is fixedly connected to the top of the connecting spring 504, and the transmission seat 505 is slidably connected to the limiting frame 503.

[0029] Specifically, such as Figure 3 As shown, a first rotating seat 506 is fixedly connected to both sides of the fixed seat 502. A damping rod 507 is hinged to the inner side of the first rotating seat 506. A second rotating seat 508 is hinged to the top of the damping rod 507. The second rotating seat 508 is fixedly connected to the bottom of the welding platform base 1.

[0030] In this embodiment: when the vibration generated during the welding process is transmitted to the welding platform base 1, the vibration is transmitted to the transmission seat 505 through the welding platform base 1. Then, the transmission seat 505 slides down along the inner side of the limiting frame 503 and compresses the connecting spring 504. Then, the connecting spring 504 absorbs part of the vibration energy through elastic deformation. At the same time, the damping rods 507 on both sides of its fixed seat 502 rotate around the first rotating seat 506 and the second rotating seat 508 with the vibration, and consume the vibration energy by utilizing their own damping characteristics. The restoring force of the connecting spring 504 and the energy dissipation effect of the damping rod 507 work together to effectively reduce the transmission of vibration to the weldment and ensure the stability of the weldment during welding.

[0031] Specifically, such as Figure 4 As shown, a high-pressure air pump 2 is fixedly connected to the outside of the clamping frame 406. A regulating valve 3 is provided at the output end of the high-pressure air pump 2. The regulating valve 3 is electrically connected to the pressure sensor 408. The output end of the high-pressure air pump 2 is connected to the elastic air cushion 407.

[0032] Specifically, such as Figure 5 As shown, a welding support frame 6 is fixedly connected to the rear side of the welding platform base 1, and a welding robotic arm 7 is fixedly connected to the top of the welding support frame 6.

[0033] In this embodiment: By setting a high-pressure air pump 2 and a regulating valve 3, the high-pressure air pump 2 works synchronously when the adaptive clamping assembly 4 is started. Its output end is connected to the elastic air cushion 407 through a pipeline to provide a gas source for the elastic air cushion 407. When the clamping frame 406 approaches the workpiece under the push of the regulating cylinder 405, the pressure sensor 408 at the top of the clamping frame 406 detects the pressure value of the high-temperature resistant clamping plate 409 in contact with the workpiece in real time, and converts the pressure data into an electrical signal and transmits it to the regulating valve 3 which is electrically connected to it. The regulating valve 3 dynamically adjusts the air supply from the high-pressure air pump 2 to the elastic air cushion 407 according to the preset clamping force threshold. If the pressure is insufficient, the regulating valve 3 increases the air supply flow, causing the elastic air cushion 407 to expand further, and the clamping force on the workpiece is enhanced by the high-temperature resistant clamping plate 409. If the pressure is too high, the regulating valve 3 reduces or cuts off the air supply to avoid the elastic air cushion 407 from over-expanding. To prevent component damage, the elastic air cushion 407 applies appropriate force to the workpiece at all times, ensuring that the workpiece does not shift during welding and protecting fragile electronic components from clamping damage. This achieves precise and controllable clamping force. By setting up a welding support frame 6 and a welding robotic arm 7, after the adaptive clamping component 4 completes the fixation of the workpiece, its welding robotic arm 7 starts according to a preset program. Based on the position parameters of the points to be welded on the workpiece, it performs movements such as movement and rotation in three-dimensional space under the guidance of the control system, achieving precise alignment between the welding head and the welding point. During the welding process, the welding support frame 6 transmits the vibration and force of the robotic arm to the welding platform base 1 through a rigid connection. Combined with the damping effect of the composite damping component 5, it reduces the shaking of the robotic arm during operation, ensuring the positional stability of the welding head at the moment of high-temperature welding, avoiding problems such as weld point misalignment and incomplete welding caused by robotic arm deviation, and ensuring welding accuracy.

[0034] Specifically, such as Figure 1 As shown, a control panel 8 is provided on the outer side of the welding platform base 1.

[0035] Specifically, such as Figure 1 As shown, a protective isolation cover 9 is fixedly connected to the front side of the welding platform base 1, and an ultraviolet-proof observation window 10 is fixedly connected to the inner side of the protective isolation cover 9.

[0036] In this embodiment: By setting up a control panel 8, the operator can input parameters such as workpiece type, size, clamping force threshold, welding temperature, and welding time through the control panel 8 before welding to complete the equipment initialization settings. During the welding process, the display screen of the control panel 8 displays the current clamping force, welding progress, and operating status of each component in real time. If an abnormality occurs, the control panel 8 will trigger an alarm and pause the operation of the relevant components. The operator can adjust the parameters in real time through the adjustment buttons on the panel to ensure that the entire welding process is carried out under controllable conditions, thereby improving operational efficiency and safety. By setting up a protective isolation cover 9 and an ultraviolet-proof observation window 10, the protective isolation cover 9 can block the sparks and high-temperature molten slag splashes generated during the welding process, protecting the operator from physical injury and harmful gas exposure. Moreover, the ultraviolet-proof observation window 10 inside the protective isolation cover 9 uses a special light-transmitting material, which can not only block the strong ultraviolet rays generated by the welding arc to avoid burning the operator's eyes and skin, but also ensure that the operator can clearly observe the clamping status of the workpiece inside the cover, the running trajectory of the welding robot arm 7, and the weld formation process.

[0037] Working Principle: During the stable welding process using this electronic component, the electronic component and the workpiece are first placed stably on the welding platform base 1, ensuring the workpiece is within the preset welding area. At this point, the drive motor 402 starts operating after power is supplied, and its output directly drives the connected drive screw 403 to rotate. Since the outer side of the drive screw 403 is threadedly connected to the moving block 404, its rotational motion is converted into horizontal linear motion of the moving block 404 along the axis of the drive screw 403. Through the forward and reverse rotation of the drive motor 402, the moving block 404 can then be adjusted until the adjusting cylinder 405 connected to the top of the moving block 404 is aligned with the part of the workpiece that needs to be clamped. Then, the adjusting cylinder 405... After startup, its output end extends outward, pushing the clamping frame 406, which is fixedly connected to it, towards the weldment. As the clamping frame 406 gradually approaches, the high-temperature resistant clamping plate 409 on the inner side of the clamping frame 406 begins to approach the surface of the weldment. Simultaneously, its pressure sensor 408 starts, constantly monitoring the pressure change when the high-temperature resistant clamping plate 409 contacts the weldment. At the same time, the high-pressure air pump 2, fixed to the outer side of the clamping frame 406, starts working. Its output end is connected to the elastic air cushion 407 through a pipeline. The high-pressure gas generated by the high-pressure air pump 2 is delivered to the interior of the elastic air cushion 407 through the pipeline, causing the elastic air cushion 407 to gradually expand. Under the expansion force of the elastic air cushion 407, the high-temperature resistant clamping plate 409 fixedly connected to the inner side of the elastic air cushion 407 further... The pressure sensor 408 then transmits the real-time pressure data detected by the pressure sensor 408 to the electrically connected regulating valve 3. The regulating valve 3 precisely controls the air supply from the high-pressure air pump 2 to the elastic air cushion 407 according to a preset clamping force threshold. When the detected pressure reaches a suitable range, the regulating valve 3 restricts the air supply from the high-pressure air pump 2, keeping the elastic air cushion 407 in a stable expansion state. This allows the high-temperature resistant clamping plate 409 to clamp the workpiece with appropriate force, ensuring that the workpiece does not shift or shake during welding, and preventing damage to fragile electronic components or the workpiece surface due to excessive clamping force. The workpiece is securely clamped in the preset position. During welding, the welding robotic arm 7 on top of the welding support frame 6 at the rear of the welding platform base 1 operates according to the preset... The program starts and begins welding the clamped and fixed workpiece. Simultaneously, the composite shock absorption assembly 5 at the bottom of the welding platform base 1 operates. The limiting frame 503 at the top of the fixed seat 502 has a frame structure, forming a vertical guide space inside. A connecting spring 504 is vertically installed inside the limiting frame 503, with its top fixedly connected to the transmission seat 505. The outer side of the transmission seat 505 slides against the inner wall of the limiting frame 503. When vibrations generated during welding are transmitted to the welding platform base 1, they are further transmitted to the transmission seat 505 connected to the bottom of the welding platform base 1. Under downward force, the transmission seat 505 slides downward along the inner wall of the limiting frame 503.Simultaneously, the connecting spring 504 is compressed. Due to its elastic deformation, the connecting spring 504 absorbs some of the vibration energy and generates an upward restoring force, thereby buffering the impact of the vibration. When the welding platform base 1 vibrates and causes up-and-down or slight horizontal swaying, it will drive the second rotating seat 508 to move synchronously, thereby causing the damping rod 507 to change angle around the hinge point of the first rotating seat 506 and the second rotating seat 508. Under the action of its own damping characteristics, the damping rod 507 consumes a large amount of vibration energy through the friction and deformation of its internal structure, further reducing the transmission of vibration to the welding platform base 1 and the workpiece. The elastic buffering of the connecting spring 504 and the energy consumption of the damping rod 507 work together to form a multiple damping effect, ensuring that the workpiece is always in a stable state during the welding process and avoiding problems such as weld point displacement and incomplete welding caused by vibration. Throughout the welding process, the operator can monitor the operation through the control panel 8 installed on the outside of the welding platform base 1. The welding parameters, such as the trajectory of the welding robotic arm 7, welding temperature, and welding time, are monitored in real time. If any abnormalities are detected, adjustments can be made promptly via the control panel 8 to ensure welding quality. The protective isolation cover 9 on the front effectively isolates the welding area from the external environment, preventing sparks, high-temperature spatter, and harmful gases generated during welding from harming the operator. Meanwhile, the UV-resistant observation window 10 on the inside allows the operator to easily observe the welding progress and the real-time status of the workpiece without opening the isolation cover. When the welding operation is completed, the welding robotic arm 7 resets, the high-pressure air pump 2 stops working and releases the gas in the elastic air cushion 407. The elastic air cushion 407 contracts, the high-temperature resistant clamping plate 409 separates from the surface of the workpiece, the output end of the adjusting cylinder 405 retracts, and the clamping frame 406 moves away from the workpiece, completing the release of the workpiece. At this point, the entire welding process is complete, and the welded workpiece can be removed for the next operation.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
