Description

Technical Field

[0001] This utility model relates to the field of wave soldering fixture technology, and in particular to a wave soldering fixture. Background Technology

[0002] Wave soldering is a surface mount soldering technique for electronic components. It involves passing a circuit board through a wave-shaped pool of molten solder to solder the component leads. To ensure efficiency and consistency in the soldering process, soldering fixtures are typically used. These fixtures help to accurately position the circuit board and ensure the soldering quality of each component during wave soldering.

[0003] Traditional wave soldering fixtures typically consist of key components, including solder bar guides, heating zones, soldering tanks, and a support platform. The solder bar guides guide the solder bar along a predetermined path into the soldering area, ensuring the solder evenly covers the soldering areas of the circuit board. The heating zone provides sufficient heat through heating elements to melt the solder bar and reach the appropriate soldering temperature. The soldering tank holds the molten solder and transfers it to the component leads via a wave motion. The support platform securely holds the circuit board, ensuring its stability during soldering and preventing shifting or shaking. These components work together to ensure smooth solder flow and precise soldering during wave soldering.

[0004] Traditional wave soldering fixtures mostly use solder bars for soldering. For wire soldering, manual feeding of the solder wire is required, which involves significant manual operation time. The speed and accuracy of the solder wire feeding are limited by the operator's skill level and the working environment. Because it is difficult to maintain a constant solder feeding speed and quality manually, uneven solder wire distribution (too much or too little) can occur, affecting the soldering effect and causing fluctuations in solder joint quality. This inefficient operation not only increases production time but also easily leads to an increased defect rate, thus impacting overall production efficiency and product quality. Utility Model Content

[0005] The purpose of this application is to provide a wave soldering fixture that addresses the problem that traditional wave soldering fixtures mostly use solder bars for soldering, while solder wire soldering requires manual feeding of the solder wire, which affects the soldering effect and causes fluctuations in the quality of the solder joints.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wave soldering fixture includes a base, a guide groove is formed on the outer wall of the base, a plurality of guide wheels are provided on the outer wall of the base, the guide wheels are horizontally aligned with the guide groove, and a clamping assembly is provided on the top of the base; The clamping assembly includes multiple fixed shafts, the bottom of which is fixedly connected to the top of the base.

[0022] 2.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Reference Figures 1-3This utility model provides an embodiment of a wave soldering fixture, including a base 1 made of cast iron, which supports all components and provides a rigid mounting base for the fixture, preventing component displacement due to vibration during the welding process and ensuring the stability of solder wire feeding and welding. This is common knowledge and will not be elaborated further here. The outer wall of the base 1 is provided with a guide groove 2, which constrains the feeding trajectory of the solder wire, causing the solder wire to move along a preset path towards the welding area, thereby preventing the solder wire from bending or shifting due to external force or its own weight, and ensuring accurate welding point positioning. The outer wall of the base 1 is provided with multiple guide wheels 3, which are horizontally aligned with the guide groove 2. The guide wheels 3 cooperate with the guide groove 2 to perform rolling guidance motion. When the solder wire passes between the guide wheel 3 and the guide groove 2, the guide wheel 3 rotates synchronously with the solder wire feeding, which not only helps to limit the position of the solder wire, but also reduces friction damage to the surface of the solder wire, thereby improving the smoothness of solder wire feeding. A clamping assembly is provided on the top of the base 1. The clamping assembly includes multiple fixed shafts 4, which provide rotation fulcrums for the clamping arms 5, constrain the movement trajectory of the clamping arms 5, and ensure that the clamping arms 5 rotate only around the fixed shafts 4, thus preventing the clamping arms 5 from deviating and causing clamping failure. The bottom of the multiple fixed shafts 4 is fixedly connected to the top of the base 1, and the outer wall of each fixed shaft 4 is rotatably connected to the clamping arms 5. The clamping arms 5 directly contact the solder wire and apply clamping force, thereby firmly fixing the solder wire above the guide groove 2 and preventing the solder wire from shaking during the conveying process. Each clamping arm 5 is provided with a spring 6 on its side wall. One end of the spring 6 is fixedly connected to the outer wall of the base 1, and the other end of the spring 6 is fixedly connected to the side wall of the clamping arm 5. An adjustment assembly is provided inside the base 1.

[0027] Reference Figures 3-5 The adjustment assembly includes multiple support platforms 10, which provide sliding support tracks for sliders 13, constrain the movement direction of sliders 13, ensure that sliders 13 slide only horizontally along support platforms 10, avoid sliders 13 offset causing guide wheel 3 position deviation, and ensure adjustment accuracy. Multiple support platforms 10 are fixedly connected inside the base 1. Multiple V-grooves 12 are opened inside the support platforms 10. V-grooves 12 cooperate with V-shaped clamps 11 for locking and positioning. When the V-shaped clamps 11 are embedded in the V-grooves 12, the movement of sliders 13 is restricted by the inclined surface engagement, thereby achieving the effect of fixing the position of sliders 13. Each support platform 10 has a slider 13 slidably connected to its outer wall. Slider 13 connects the fixing part 9 to the support platform 10. By sliding along the support platform 10, slider 13 drives the fixing part 9 and guide wheel 3 to move synchronously, thereby realizing the adjustment of the position of guide wheel 3 and adapting to different specifications of solder wire. Reference Figures 3-5Each slider 13 has a fixed fastener 9 fixedly connected to its upper surface, and a fixed frame 7 fixedly connected to the side wall of each fastener 9. The fixed frame 7 fixes the bearing 8 and connects to the fastener 9, providing a mounting carrier for the bearing 8 and ensuring that the bearing 8 stably supports the guide wheel 3, preventing the guide wheel 3 from shaking when rotating. Each fixed frame 7 has a fixed bearing 8 fixedly connected inside, and the bearing 8 is located inside the guide wheel 3. An inner plate 14 is fixedly connected inside the slider 13, and multiple connecting shafts 16 are fixedly connected to both sides of the inner plate 14. The connecting shafts 16 cooperate with the operating plate 15 to slide and guide, constraining the operation. The direction of movement of plate 15 ensures that the operating plate 15 moves only along the axial direction of the connecting shaft 16, avoiding the offset of the operating plate 15 and causing the V-shaped clamping plate 11 to deviate in alignment. Multiple operating plates 15 are slidably connected inside the slider 13. The operating plates 15 are slidably connected to the outer wall of the connecting shaft 16. A V-shaped clamping plate 11 is fixedly connected to the lower surface of each operating plate 15. The V-shaped clamping plate 11 engages with the V-shaped groove 12. A second spring 17 is sleeved on the outer wall of each connecting shaft 16. One end of the second spring 17 is fixedly connected to the side wall of the inner plate 14, and the other end of the second spring 17 is fixedly connected to the side wall of the operating plate 15.

[0028] Working principle: First, the solder wire passes through the guide wheel 3 from above. The guide wheel 3 rotates freely through the bearing 8, reducing friction damage to the surface of the solder wire. The guide groove 2 is coaxially aligned with the guide wheel 3 to form a guide channel, allowing the solder wire to be conveyed along a preset straight trajectory. At the same time, the clamping arm 5 is hinged to both sides of the base 1. The elastic restoring force of the spring 6 drives the clamping arm 5 to rotate synchronously inward, applying a continuous clamping force to the solder wire above the guide groove 2. This replaces manual holding of the solder wire and spring 6 replaces manual force control, preventing the solder wire from shaking or deviating, ensuring accurate conveying position, and solving the defects of poor accuracy and low stability of manual solder feeding. Pressing the operating plate 15 compresses the second spring 17, causing the operating plate 15 to slide along the connecting shaft 16. This causes the V-shaped clamping plate 11 to disengage from the V-groove 12 of the support platform 10. At this time, the slider 13 can slide along the support platform 10 to adjust its position. After releasing the operating plate 15, the second spring 17 returns to its original position, pushing the V-shaped clamping plate 11 into the corresponding V-groove 12, fixing the position of the slider 13. The slider 13 drives the guide wheel 3 to move synchronously through the fixing part 9 and the fixing frame 7, so that the guide wheel 3 cooperates with the guide groove 2 to form a conveying channel adapted to the specifications of the solder wire, realizing stable guiding and conveying of the solder wire, replacing manual solder feeding to improve accuracy.
