Technical Field

[0001] This utility model relates to the field of fuse manufacturing technology, specifically a solder ball testing mechanism. Background Technology

[0002] Currently, fuses with solder balls have solder balls that melt upon heating and move within a specific structure, altering the fuse's conductivity and ultimately cutting off the circuit for protection. They are primarily used in high-precision electronic equipment, as solder balls allow for more accurate overcurrent responses, reducing the risk of damage. Fuse without solder balls, on the other hand, rely solely on their inherent properties to melt and are more commonly used in general electronic equipment and household appliances.

[0003] Existing fuse soldering equipment that integrates soldering, wire threading, and wire cutting lacks a solder ball detection mechanism. This often results in misaligned solder balls or missing solder balls, both of which further impair the wire threading and cutting processes, consequently affecting equipment stability and product yield. Therefore, there is an urgent need to provide a solder ball detection mechanism to overcome these shortcomings in current applications. Summary of the Invention

Detailed Implementation

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1-3 ,exist Figure 3 In this embodiment, a solder ball detection mechanism is provided, wherein a fuse tube 25 is provided with a wire 26 and a solder ball 27 is located in the middle position. This embodiment of the present invention provides a solder ball detection mechanism, which is installed in a soldering mechanism. The solder ball detection mechanism includes:

[0028] The fixing plate 14 and the connecting plate 15 disposed on the fixing plate 14 are provided. The soldering mechanism is also provided with a guide rail 13, and the fixing plate 14 and the guide rail 13 are connected by a slider.

[0029] A first pressing component for limiting the wire 26 is disposed on the fixing plate 14, and a second pressing component for limiting the solder ball 27 is also disposed on the fixing plate 14.

[0030] And a detection component located between the first pressing component and the second pressing component, the detection component including a photoelectric switch 21 and a swing rod 20 for blocking the photoelectric switch 21, the swing rod 20 being connected to the fixed plate 14 via a rotating component, the photoelectric switch 21 being disposed on the fixed plate 14;

[0031] The rotating component includes a bearing 23 and a positioning pin 16. The bearing 23 is disposed on the fixed plate 14, and the swing rod 20 is connected to the bearing 23 through the positioning pin 16.

[0032] The first pressing assembly includes a wire pressing cylinder 19 and a top block 17 for use in conjunction with the wire pressing cylinder 19. The wire pressing cylinder 19 and the top block 17 are mounted opposite each other in the fixing plate 14.

[0033] The second pressing assembly includes a wire pressing cylinder 22 and a top block 23 for use in conjunction with the wire pressing cylinder 22. The wire pressing cylinder 22 and the top block 23 are mounted opposite to each other in the fixing plate 14.

[0034] The fixing plate 14 is also provided with hooks 18;

[0035] The soldering mechanism includes a frame and a wire feeding motor 1, a tensioning mechanism 2, a cutting mechanism 5, a wire feeding mechanism, a solder feeding mechanism 8, a wire cutting mechanism 11, and a wire clamping mechanism 12 mounted on the frame.

[0036] The cutting mechanism 5 is also equipped with a heating block 3;

[0037] The cutting mechanism 5 includes a cutter 4 for cutting tin;

[0038] The wire feeding mechanism includes a wire feeding motor 6, a large wire feeding cylinder 9, and a small wire feeding cylinder 10 mounted on the frame;

[0039] The solder feeding mechanism 9 includes a solder feeding nozzle 7 mounted on the frame.

[0040] In this embodiment of the invention, the wire feeding motor 1 first feeds the wire onto the wire shaft. After passing through the tensioning mechanism 2 and the wire feeding mechanism, the wire is fed to the solder feeding nozzle 7. The solder feeding mechanism 8 feeds the solder wire out, and at the same time, the cutting mechanism cuts the solder wire and melts the cut solder into the spherical groove of the cutter 4. Then, the wire carries the solder ball away to cool, thus completing the soldering of the wire. The solder ball detection mechanism is installed in the wire threading mechanism. The wire pressing cylinder 19 is used to clamp the wire and maintain its position, and the wire pressing cylinder 22 is used to hold the solder ball in place. When the large wire feeding cylinder 9 and the small wire feeding cylinder 10 are reset, the slider drives the entire solder ball detection mechanism to move from bottom to top. After the swing rod 20 contacts the solder ball, it swings upwards through the linkage with the positioning pin 16 and the bearing 23. When the left end of rod 20 swings downward, the photoelectric switch 21 lights up when blocked, indicating the presence of a solder ball; otherwise, it does not light up, indicating the absence of a solder ball. When a solder ball is detected, the wire-pressing cylinders 1-19 and 2-22 simultaneously press down. Then, as the wire-feeding cylinder 9 moves downward, the wire-pressing cylinder 1-19 simultaneously releases, allowing the needle to penetrate the ceramic tube. The wire-feeding cylinder 10 moves downward, and the lower wire-clamping mechanism 12 clamps it tightly. The wire then moves downward, delivering the solder ball to the center of the ceramic tube. The wire-pressing cylinder 2-22 then releases, and the wire-feeding cylinders 9 and 10 return to their original positions. When the wire-feeding cylinder 9 is in position, the wire-pressing cylinders 1-19 and 2-22 simultaneously press down, and the wire-cutting mechanism 11 cuts the wire, completing the wire-threading process. When the wire-feeding cylinder 9 is in position... After determining whether a solder ball is present, the wire threading action is the same as when a solder ball is present. However, after proceeding to the next soldering process, the fuse tube will not be soldered, and the fuse tube without a solder ball will be recycled by the subsequent process. When the wire cutting mechanism 11 cuts the wire, the solder ball on the wire will have a slight vertical displacement. Because the wire feeding cylinder 9 moves downward while the wire pressing cylinder 19 is simultaneously released, the wire pressing cylinder 22 is still pressing on the fixed block. The solder ball will always be located below the top block 23. In this way, the solder ball will always remain in the center of the fuse tube wire. At this time, the solder ball detection mechanism has the ability to determine the presence or absence of solder balls and ensure that the solder ball is always in the center of the fuse wire. This ensures the stability of the wire threading mechanism and the wire cutting position. This invention eliminates deviations, fundamentally solving the problem of defective products and avoiding waste of costs and resources. It offers several significant advantages: First, it greatly enhances product stability, ensuring the solder ball remains centered on the fuse wire. Second, it creates an ideal operating environment for the wire threading and cutting mechanisms of the fuse equipment, enabling stable and efficient continuous operation. Third, it significantly reduces the defect rate, controlling product quality from the source and saving companies substantial costs and resources. Fourth, the application of this integrated equipment represents a major advancement in fuse production technology, setting a new benchmark for the industry and leading fuse production to a higher level of development.
