[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0016] The present application relates to a circuit board cutting device, such as Figure 1-7 As shown, the cutting device includes a frame 4 for serving as a basic support, and a cutting component 3 for cutting the circuit board is arranged in the vertical direction of the frame 4. As the saw belt 6 is used for a longer time, it will stretch and deform. Therefore, in order to prevent the saw belt 6 from getting stuck due to loosening, an adjusting component 1 is added to the top of the frame 4, which can pull the cutting component 3 to adjust the tension of the saw belt 6. After the saw belt 6 contacts the circuit board, high-frequency vibration will occur. In order to prevent the saw belt 6 from breaking due to excessive vibration amplitude, a supporting component 2 is added to the upper part of the frame 4 to support the saw belt 6 for earthquake resistance.

[0017] The cutting assembly 3 includes a motor 7, a pulley 5, and a saw belt 6. There are two pulleys 5, which are arranged side by side and at intervals in the vertical direction of the frame 4. A saw belt 6 for cutting circuit boards is wound around the upper part of the pulley 5. A motor 7 connected to the pulley 5 and used to provide a power source is arranged on one side of the lower pulley 5, and an adjustment assembly 1 connected to the pulley 5 and used to adjust its vertical height to change the tension of the saw belt 6 is arranged on one side of the upper pulley 5.

[0018] The adjusting assembly 1 includes a gate plate 10, a screw rod 9, a screw block 8, and a pressure rod 11. The gate plate 10 is arranged in the vertical direction inside the frame 4 and is connected to the pulley 5 at the top. The upper end of the gate plate 10 is arranged with a screw rod 9 connected to it through a bearing 14. In order to be able to use the screw rod 9 to push the gate plate 10 to perform vertical lifting and lowering movements, a screw block 8 threadedly connected to the screw rod 9 is arranged on the top of the frame 4, so that the gate plate 10 is controlled to perform vertical lifting and lowering movements through the threaded connection between the screw rod 9 and the screw block 8. In order to be able to effectively fix the pulley 5 at the top, a pressure rod 11 threadedly connected to it and capable of abutting against the side wall of the gate plate 10 is also provided on one side of the frame 4.

[0019] The supporting assembly 2 includes a raft 12, a support block 13, and a bearing 14. The raft 12 is arranged on the upper part of the frame 4 and arranged side by side with the saw band 6. The raft 12 is connected to the frame 4 by bolts and can be adjusted in the vertical direction of the frame 4. There are two support blocks 13, one of which is arranged at the lower end of the raft 12, and the other is arranged on the upper part of the frame 4. A plurality of bearings 14 for supporting the saw band 6 are arranged on one side of the support block 13, and the bearings 14 respectively abut against the two sides and the back of the saw band 6, thereby preventing the saw band 6 from generating a large amplitude during the cutting process.

[0020] When in use, the pulley 5 is driven to rotate by the motor 7, and the pulley 5 drives the saw belt 6 connected to the upper part to quickly cut the circuit board, and the screw 9 arranged on the top of the frame 4 can control the gate plate 10 connected to the upper pulley 5 to perform vertical lifting operations by rotating around the screw block 8, so that the spacing between the pulleys 5 is changed, and the tension of the saw belt 6 is increased. The raft plate 12 on the upper part of the frame 4 can change the spacing between the two support blocks 13 by adjusting its vertical position, and then the saw belt 6 in cutting can be positioned with the help of the bearing 14 on the upper part of the support block 13.
