Description

Technical Field

[0001] This utility model relates to the field of solder bar technology, and in particular to a solder bar processing and cutting device. Background Technology

[0002] Solder bars are rod-shaped materials made primarily of metallic tin. They are commonly used in fields such as electronic welding, fuses, and industrial equipment. They are used to cut and resolve welding defects and replace failed components.

[0003] Patent application publication number CN218311253U discloses a cutting device for producing lead-free solder bars. It includes a worktable and lead-free solder bars. One end of the worktable has a through hole in its inner wall. The device also includes a cutting assembly for cutting the lead-free solder bars. The cutting assembly includes a steel wheel located inside the through hole. The inner wall of the steel wheel is detachably connected to several cutting blades arranged in a ring via a fixing assembly. When using this patent, the solder bars are conveyed to the cutting insertion hole via a wire conveying device. A servo motor drives the rotating shaft, steel wheel, and cutting blades to rotate, causing the cutting blades to cut the solder bars. However, the aforementioned prior art only supports the middle of the solder bar with a support plate. When cutting long or heavy solder bars, gravity can easily cause the ends of the solder bars to sag and the entire bar to bend, affecting cutting accuracy.

[0004] In view of the existing patents, there is a need to provide a solder bar processing and cutting device with multi-point support. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which use a support plate to support the middle of the solder bar, the ends of the solder bar tend to droop and the whole bar bends due to gravity when cutting long or heavy solder bars, thus affecting the cutting accuracy, this utility model provides a solder bar processing and cutting device with multi-point support.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a solder bar processing and cutting device, comprising a mounting bracket, a limiting block, a control rod, an arc-shaped cutter, a control cylinder, rolling wheels, and a servo motor. Two control rods are threaded onto the mounting bracket, with the limiting block fixedly connected to each control rod. A control cylinder is mounted on the mounting bracket, and the arc-shaped cutter is mounted on the telescopic rod of the control cylinder. Two rolling wheels are rotatably mounted on the mounting bracket. A servo motor is mounted on the mounting bracket, and the output shaft of the servo motor is connected to the adjacent rolling wheel. The device also includes a mounting frame, a limiting frame, a guide rod, a limiting plate, and a bidirectional screw. A mounting frame is fixedly connected to the mounting bracket, and a limiting frame is fixedly connected to the mounting frame. Two limiting plates are slidably mounted on the limiting frame, and a bidirectional screw is threaded between the two limiting plates. A guide rod is fixedly connected to the limiting plate 11, and the limiting plate slides on the guide rod.

[0007] More preferably, it also includes a collection frame, a discharge block, a gas distribution pipe and a gas delivery pipe. The collection frame is fixedly connected to the mounting bracket, two discharge blocks are fixedly connected inside the collection frame, two gas distribution pipes are connected to the collection frame, and a gas delivery pipe is connected between the two gas distribution pipes.

[0008] More preferably, it also includes a feeding ring, which is rotatably mounted on the limiting frame.

[0009] More preferably, a rubber pad is provided inside the limiting block.

[0010] More preferably, the limiting plate is equipped with an anti-slip pad.

[0011] More preferably, two levers are fixedly connected to the bidirectional screw.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By rotating two bidirectional screws, the two bidirectional screws drive the two limiting plates on themselves to move closer synchronously, thereby supporting and fixing the left and right sides of the solder bar, thereby improving the three-point support points, effectively suppressing the deformation and vibration of the solder bar, and ensuring the quality of the cut surface.

[0013] 2. The system is connected to an external air pump and collection box via an air supply pipe. The external air pump draws air into the unloading block through the air supply pipe and the air distribution pipe, causing the solder bar waste in the collection frame to be sucked into the unloading block and finally into the collection box. This automatically cleans up the debris and guides it to be discharged in a concentrated manner, effectively controlling the spread of dust. Attached Figure Description

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] Example 1: A solder bar cutting device, see reference Figure 1 and Figure 2 As shown, the assembly includes a mounting bracket 1, a limiting block 2, control rods 3, an arc-shaped cutter 4, a control cylinder 5, rolling wheels 6, and a servo motor 7. Two control rods 3 are threaded onto the right side of the mounting bracket 1, with the inner ends of the control rods 3 fixedly connected to the limiting blocks 2. The two limiting blocks 2 are used to fix the ends of the solder bars. A control cylinder 5 is bolted to the middle of the mounting bracket 1, and an arc-shaped cutter 4 is mounted on the extension rod of the control cylinder 5. Two rolling wheels 6 are rotatably mounted on the rear of the mounting bracket 1. The mounting bracket 1 is bolted to... The system includes a servo motor 7, whose output shaft is connected to a nearby rolling wheel 6. It also includes a mounting bracket 8, a limit bracket 9, a guide rod 10, a limit plate 11, and a bidirectional screw 12. The mounting bracket 1 has mounting brackets 8 welded to both the front and rear. The mounting bracket 8 has a limit bracket 9 welded to it. The limit bracket 9 has two limit plates 11 that slide on it. The two limit plates 11 are connected by a bidirectional screw 12 threaded between them. The limit plate 11 is fixedly connected to the guide rod 10 and slides on the guide rod 10.

[0020] See Figure 2 As shown, it also includes a material conveying ring 17, which is rotatably mounted in the middle of the limiting frame 9.

[0021] See Figure 1 As shown, a rubber pad is provided inside the limiting block 2.

[0022] See Figure 2 As shown, an anti-slip pad is provided on the inner side of the limiting plate 11.

[0023] See Figure 2 As shown, both ends of the bidirectional screw 12 are fixedly connected to a lever.

[0024] When this device is needed, the solder bar is passed between the two limiting blocks 2, and then the solder bar is pushed further so that it passes between the arc-shaped cutter 4 and the mounting bracket 1, and the end of the solder bar is positioned between the two rolling wheels 6. Then, the servo motor 7 is started, and the servo motor 7 drives the rolling wheels 6 to rotate, causing the solder bar to be fed axially, so that the solder bar moves to the appropriate position. After moving to the appropriate position, the servo motor 7 is paused, and then the two control rods 3 are rotated, so that the two control rods 3 drive the two limiting blocks 2 to clamp the end of the solder bar, ensuring that the solder bar does not shift during cutting. Then, the two bidirectional screws 12 are rotated, and the bidirectional screws 12 drive the two limiting plates 11 on them to move closer synchronously, so as to support and fix the left and right sides of the solder bar, thereby improving the three-point support point, effectively suppressing the deformation and vibration of the solder bar, and ensuring the quality of the cut surface. The feeding ring 17 in the middle of the limiting frame 9 supports the solder bar and reduces the conveying friction. After fixing, the control cylinder 5 is started, and the extension rod of the control cylinder 5 drives the arc-shaped cutter 4 to move downward to cut.

[0025] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a collection frame 13, a discharge block 14, a gas distribution pipe 15, and a gas delivery pipe 16. The collection frame 13 is fixedly connected to the middle of the mounting bracket 1. The collection frame 13 is located below the arc-shaped cutter 4. Two discharge blocks 14 are fixedly connected inside the collection frame 13. Two gas distribution pipes 15 are connected to the bottom of the collection frame 13. A gas delivery pipe 16 is connected between the ends of the two gas distribution pipes 15. The gas delivery pipe 16 is connected to an external air pump.

[0026] During cutting, the air supply pipe 16 is connected to an external air pump and a collection box. The external air pump draws air into the unloading block 14 through the air supply pipe 16 and the air distribution pipe 15, so that the solder bar waste in the collection frame 13 is drawn into the unloading block 14 and finally enters the collection box. This automatically cleans up the debris and guides it to be discharged in a concentrated manner, effectively controlling the spread of dust.
