[0027] Example 1:

[0028] Reference Figure 1-5A bonding silver wire production and cutting device includes a base plate 1, a mounting plate 3 fixedly connected to the top of the base plate 1, a pulling assembly 2 mounted on the surface of the mounting plate 3, the pulling assembly 2 including an adjusting threaded rod 21, the left end of the adjusting threaded rod 21 being movably connected to the surface of the left side of the mounting plate 3 via a bearing, a first motor 23 fixedly connected to the right side of the right side of the mounting plate 3, a movable plate 24 threadedly fitted onto the surface of the adjusting threaded rod 21, a connecting frame 27 fixedly connected to the top of the movable plate 24, and the top of the base plate 1 being fixedly connected to... There is a mounting bracket 5, and a tensioning component 6 is mounted on the surface of the mounting bracket 5. The tensioning component 6 includes an L-shaped plate 63, and a rotating rod 61 is provided through the surface of the L-shaped plate 63. The rotating rod 61 is cylindrical and has threads on its surface to facilitate the fitting of the clamping nut 65. The connection between the rotating rod 61 and the L-shaped plate 63 is movably connected by a bearing. The clamping nut 65 is threaded on the surface of the rotating rod 61. An anti-slip washer is bonded to the side of the clamping nut 65 that is in contact with the bonding silver wire, which can effectively ensure the anti-slip effect of the clamping nut 65.

[0029] A circular rod 7 is provided through the rear side of the mounting bracket 5. A pulley 62 is fixedly sleeved on the rear end of the rotating rod 61 and the circular rod 7 below. A belt 64 is connected to the surface of the pulley 62 for transmission.

[0030] In use, remove the front clamping nut 65, then put the bonding silver wire roll on the rotating rod 61, pull the bonding silver wire to pass through the circular rod 7, stretch it onto the moving plate 24, and use the electric telescopic rod 25 to lower the anti-slip pressure plate 26 to press the bonding silver wire. Then, put the clamping nut 65 back on the rotating rod 61 to press and fix the bonding silver wire roll. After fixing, the first motor 23 drives the adjusting thread rod 21 to rotate. Under the guidance of the guide rod 22, the moving plate 24 moves to the right to automatically pull the bonding silver wire.

[0031] Simultaneously, the second motor 4 drives the lower circular rod 7 to rotate. Under the action of the linkage gear 12, the upper circular rod 7 rotates accordingly. At the same time, under the action of the pulley 62 and belt 64, the rotating rod 61 rotates accordingly, feeding the bonding silver wire. When the moving plate 24 pulls the bonding silver wire to the appropriate length, the second motor 4 reverses, and the pulley 62 and belt 64 reverse the rotating rod 61, which can tighten the bonding silver wire, thereby ensuring the cutting quality.

[0032] After the cutting is completed, the moving plate 24 can be moved to the right side of the support plate 10, and the bonding silver wire can be fed to the right by rotating the rod 61 again, so that it can be fed onto the moving plate 24 and pressed by the anti-slip pressure plate 26, so as to carry out the next pull cutting.

[0033] like Figure 2 and Figure 3The left end of the first motor 23 shaft passes through to the left side of the mounting plate 3 on the right side and is fixedly connected to the right end of the adjusting threaded rod 21. A guide rod 22 is provided through the surface of the moving plate 24. Both the left and right ends of the guide rod 22 are fixedly connected to the surface of the mounting plate 3. The guide rod 22 is made of metal material and there are two of them. It can effectively support the moving plate 24 and ensure the stability of the moving plate 24.

[0034] The guide rod 22 is designed to guide the movable plate 24, allowing the movable plate 24 to move when the adjusting threaded rod 21 rotates.

[0035] like Figure 2 and Figure 3 An electric telescopic rod 25 is installed through the top of the connecting frame 27. The connecting frame 27 is U-shaped and can effectively support the electric telescopic rod 25. An anti-slip pressure plate 26 is fixedly connected to the bottom end of the electric telescopic rod 25.

[0037] like Figure 1 and Figure 4 The second motor 4 is fixedly connected to the surface of the mounting bracket 5. The mounting bracket 5 has a U-shaped design, which can effectively support objects in multiple directions. The rear end of the shaft of the second motor 4 passes through the surface of the mounting bracket 5 and is fixedly connected to the front end of the circular rod 7 below.

[0038] like Figure 1 and Figure 4 The inner cavity of the mounting frame 5 is fixedly connected to a support plate 10. There is one support plate 10. It can support the bonding silver wire during cutting, making it convenient to cut. The top of the mounting frame 5 is fixedly connected to a hydraulic cylinder 9. The bottom end of the hydraulic cylinder 9 extends through the inner cavity of the mounting frame 5 and is fixedly connected to a cutter 11.

[0039] The hydraulic cylinder 9 is designed to push the cutter 11 down, thereby cutting the bonded silver wire.

[0040] like Figure 1 and Figure 4 The top of the cutter 11 is fixedly connected with a stabilizing rod 8. There are two stabilizing rods 8, which can ensure the stability of the cutter 11 when cutting. The top of the stabilizing rod 8 extends through to the top of the mounting bracket 5.

[0041] like Figure 1 , Figure 4 and Figure 5 The rear end of the rotating rod 61 is fixedly fitted with a linkage gear 12, and the two linkage gears 12 mesh with each other. The rear end of the L-shaped plate 63 is fixedly connected to the inner wall of the mounting bracket 5.

[0042] Through the design of the linkage gear 12, when the second motor 4 is running, the two circular rods 7 can rotate simultaneously, thereby conveying the bonding silver wire.

[0043] 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.
