Description

Technical Field

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

[0002] With the development of electronic technology, the demand for solder wire is particularly large. Solder wire is also known as solder wire, tin wire, or tin wire. Solder wire is composed of two parts: tin alloy and additives. The alloy composition is divided into tin-lead and lead-free additives, which are evenly poured into the middle part of the tin alloy. When it is soldered to the circuit board, it often needs to be cut by a cutting device.

[0003] Existing solder wire cutting devices either have too loose or too tight clamping force between the device and the winding drum, making it difficult for the winding drum to unwind the solder wire wrapped around its outer wall, resulting in low cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing solder wire cutting devices have either too loose or too tight clamping force between the device and the winding drum, making it difficult for the winding drum to unwind the solder wire wrapped around its outer wall, resulting in low cutting efficiency. Therefore, this invention proposes a solder wire cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solder wire cutting device, comprising:

[0007] The support frame has a sliding column installed at its rear interior. One end of the sliding column, which extends into the support frame, is connected to a spring. The other end of the spring is connected to the support frame. The other end of the sliding column is threadedly connected to a threaded rod, one end of which holds a winding spool. A support seat is installed on one side of the front interior of the support frame, and a support groove is formed on one side of the support seat. A pressing frame extends through one side of the support frame, and one end of the pressing frame is connected to a cutting scissor. The pressing frame is connected to the support frame via a telescopic rod, and a fixed frame is installed on the front interior of the support frame.

[0008] Preferably, a sliding groove is provided at the rear of the inner wall of the support frame, and the sliding groove and the sliding column are slidably connected.

[0009] Preferably, the threaded rod has an L-shaped structure, and there are two sets of threaded rods.

[0010] Preferably, a through groove is provided on the inner side of the fixing frame.

[0011] Preferably, a reserved groove is provided on the inner side of the bearing seat.

[0012] Preferably, the inner side of the reserved groove is connected to the inner side of the bearing groove, and the bearing groove has a semi-cylindrical structure.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up the threaded rod, sliding column and bearing frame, the L-shaped threaded rod can be adjusted to adjust its length with the sliding column, which facilitates the threaded rod to be inserted into the inner side of the winding drum for clamping operation. Moreover, the outer wall of the threaded rod that extends into the winding drum is inlaid with balls, so that the winding drum is neither too loose nor too tight, which facilitates the unloading of solder wire and the cutting of solder wire, thereby improving work efficiency.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3A solder wire cutting device includes a support frame 1. A sliding post 2 is installed at the rear of the inside of the support frame 1. One end of the sliding post 2 extends into the support frame 1 and is connected to a spring 3. The other end of the spring 3 is connected to the support frame 1. The other end of the sliding post 2 is threadedly connected to a threaded rod 5. One end of the threaded rod 5 clamps a winding drum. The threaded rod 5 has an L-shaped structure and is distributed in two sets. The outer wall of the threaded rod 5 extending into the winding drum is inlaid with balls to facilitate smooth unwinding of the winding drum after clamping it. A groove 4 is opened at the rear of the inner wall of the support frame 1. The groove 4 and the sliding post 2 are slidably connected. When placing winding drums of different specifications, the sliding post 2 can be moved along the groove 4 so that the sliding post 2 and the threaded rod 5 can clamp the winding drums of different specifications.

[0022] A support seat 10 is installed on one side of the inner front of the support frame 1, and a support groove 12 is opened on one side of the support seat 10. A reserved groove 11 is opened on the inner side of the support seat 10. The reserved groove 11 is mainly designed to provide space for the cutting scissors 7 to cut the solder wire in the support groove 12, so that the cutting scissors 7 will not make rigid contact with the support seat 10. The inner side of the reserved groove 11 is connected to the inner side of the support groove 12, and the support groove 12 has a semi-cylindrical structure. The support groove 12 is mainly for facilitating the placement of the solder wire so that the cutting scissors 7 can complete the cutting work. A pressing frame 9 passes through one side of the support frame 1, and one end of the pressing frame 9 is connected to the cutting scissors 7. The scissors 7 and the pressing frame 9 are connected to the support frame 1 via the telescopic rod 8. A fixed frame 6 is installed inside the front of the support frame 1. The telescopic rod 8 consists of a thick telescopic rod, a thin telescopic rod, and an elastic element. The thick telescopic rod is fixedly connected to the inner wall of the support frame 1. The thin telescopic rod can move along the inner wall of the thick telescopic rod and is pulled by the elastic element, thus assisting the pressing frame 9 in rebounding and resetting. A through groove 13 is provided on the inner side of the fixed frame 6. The through groove 13 is mainly to facilitate the movement of the scissors 7 into and out of the fixed frame 6. The scissors 7 is located inside the fixed frame 6, which can effectively prevent the scissors 7 from being exposed when not in use, thus preventing injury.

[0023] Working principle: In use, the operator first adjusts the length between the threaded rod 5 and the sliding column 2 according to the size of the winding drum, so that the assembly can clamp the inside of the winding drum. At the same time, the sliding column 2 moves along the slide groove 4 to facilitate clamping winding drums of different heights. Then, the solder wire is pulled out and placed in the bearing groove 12. When it needs to be cut, the operator pushes the pressing frame 9 to move the cutting scissors 7 out of the through groove 13 of the fixed frame 6 to cut the solder wire in the bearing groove 12. Finally, the device achieves the cutting of solder wire.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
