Description
Technical Field
[0001] This utility model relates to the technical field of solder bar cutting devices, and in particular to an automatic solder bar cutting and positioning device. Background Technology
[0002] Solder bars are a type of solder product, available in both leaded and lead-free varieties, both used for soldering circuit boards. Made of pure tin, they offer good wettability and fluidity, making them easy to solder. They produce bright, full solder joints without defects such as cold solder joints. With the addition of sufficient antioxidants, they possess strong oxidation resistance. Made entirely of pure tin, they produce less solder dross, reducing unnecessary waste. Solder bars cast and cooled using traditional molds often have uneven end faces, leading to inconsistent finished product dimensions. Therefore, they require length-cutting to ensure uniformity in length.
[0003] Existing automatic solder bar cutting devices are not convenient for limiting the cutting of solder bars of different widths. To overcome these disadvantages, this invention provides an automatic solder bar cutting and positioning device. Utility Model Content

[0028] like Figure 1-6 As shown, an automatic solder bar cutting and positioning device is disclosed, comprising a base 1, with supporting feet 2 fixedly connected to the four corners of the bottom end of the base 1. A sliding groove 19 is provided near the front of the bottom end of the base 1, and a bidirectional screw 20 is rotatably connected inside the sliding groove 19. Mounting brackets 3 are provided on both the left and right sides of the base 1, and a second slider 24 is fixedly connected to one end of each mounting bracket 3. The second slider 24 is slidably connected to the sliding groove 19, and the second slider 24 is threadedly connected to one side of the bidirectional screw 20. The other end of the mounting bracket 3 is fixedly connected to a mounting bracket. The housing 4 is equipped with several limiting wheels 5 rotatably connected inside the housing 4. A support frame 6 is fixedly connected to the front side of the upper end of the base 1. A pusher frame 8 is provided on the rear side of the support frame 6. A pusher assembly 7 for driving the pusher frame 8 to move back and forth is fixedly connected to the upper end of the support frame 6. A lifting plate 10 is provided on the rear side of the upper end of the base 1. Lifting assemblies 9 for adjusting the height of the lifting plate 10 are provided on the left and right ends of the rear side of the upper end of the base 1. A cutting assembly 11 is provided on the rear side of the bottom end of the lifting plate 10. A limiting assembly 12 is provided on the front side of the bottom end of the lifting plate 10.
[0029] As shown in the figure, a third servo motor 21 is fixedly connected to the right side of the base 1, and the output end of the third servo motor 21 is fixedly connected to one end of the bidirectional screw 20.
[0030] As shown in the figure, the propulsion assembly 7 includes a first slide rail 13 fixedly connected to the support frame 6. A first screw 14 is rotatably connected inside the first slide rail 13. A first servo motor 15 is fixedly connected to the front end of the first slide rail 13. The output end of the first servo motor 15 is fixedly connected to the front end of the first screw 14. The pusher frame 8 includes a first slider 25. The first slider 25 is slidably connected to the first slide rail 13. The first slider 25 is threadedly connected to the first screw 14. A push plate 26 is fixedly connected to the bottom end of the first slider 25. The first servo motor 15 drives the first screw 14 to rotate, which can drive the pusher frame 8 to move along the first slide rail 13 through the first slider 25. Thus, the push plate 26 can drive the solder bar to move along the limiting wheel 5, which is convenient for cutting the solder bar to a fixed length.
[0031] As shown in the figure, the lifting assembly 9 includes second slide rails 16 fixedly connected to the left and right sides of the upper end of the base 1. Each second slide rail 16 is rotatably connected to a second screw 17. Each second screw 17 has a sprocket 22 fixedly connected to its bottom end. The sprockets 22 are driven by a chain 23. A second servo motor 18 is fixedly connected to the upper end of one side of the second slide rail 16. The output end of the second servo motor 18 is fixedly connected to the upper end of the corresponding second screw 17. The lifting plate 10 has two ends slidably connected to the corresponding second slide rails 16 and two ends threadedly connected to the corresponding second screws 17. The second servo motor 18 drives the corresponding second screw 17 to rotate. Through the transmission of the sprockets 22 and the chain 23, it can drive the other second screw 17 to rotate, thus moving the lifting plate 10 along the second slide rail 16. This allows the cutting assembly 11 and the limiting assembly 12 to be adjusted.
[0032] As shown in the figure, the cutting assembly 11 includes a fixed plate 27 fixedly connected to the bottom end of the lifting plate 10. A drive motor 28 is fixedly connected to the rear side of the fixed plate 27. A cutting blade 29 is fixedly connected to the output end of the drive motor 28.

[0033] As shown in the figure, the limiting component 12 includes a telescopic rod 30 fixedly connected to the bottom end of the lifting plate 10. A pressure plate 31 is fixedly connected to the bottom end of the telescopic rod 30. A spring 32 is sleeved on the outside of the telescopic rod 30. The upper and lower ends of the spring 32 are fixedly connected to the lifting plate 10 and the pressure plate 31, respectively. When the limiting component 12 descends, the pressure plate 31 contacts the upper end of the solder bar, which can compress the spring 32 and the telescopic rod 30. The solder bar can be cut by the cutting component 11.
[0034] Working principle: In use, the solder bar to be cut is placed between the mounting housings 4. The third servo motor 21 drives the bidirectional screw 20 to rotate, which in turn moves the second slider 24 along the slide groove 19, thereby moving the mounting frame 3. This allows adjustment of the spacing between the mounting housings 4, enabling several limiting wheels 5 to limit the solder bar on both sides, thus limiting solder bars of different widths. The propulsion component 7 drives the pusher frame 8 to move. Specifically, the first servo motor 15 drives the first screw 14 to rotate, which in turn moves the pusher frame 8 along the first slide rail 13 via the first slider 25. This allows the pusher plate 26 to move the solder bar along the limiting wheels 5, facilitating fixed-length cutting of the solder bar. The height of the lifting plate 10 can be adjusted by the lifting assembly 9. Specifically, the second servo motor 18 drives the corresponding second screw 17 to rotate. Through the transmission of the sprocket 22 and the chain 23, it can drive another second screw 17 to rotate, which can drive the lifting plate 10 to move along the second slide rail 16. This can drive the cutting assembly 11 and the limiting assembly 12 to be adjusted. The limiting assembly 12 can fix and limit the upper end of the solder bar. Specifically, when the limiting assembly 12 descends, the pressure plate 31 contacts the upper end of the solder bar, which can compress the spring 32 and the telescopic rod 30. The cutting assembly 11 can cut the solder bar. Specifically, the drive motor 28 drives the cutting blade 29 to rotate, which can cut the solder bar.
