Description

Technical Field

[0001] This utility model relates to the field of PCB substrate technology for inductors, specifically to a PCB substrate cutting device for inductors. Background Technology

[0002] The PCB substrate for inductors is a key basic component in the inductor manufacturing process. It provides a stable carrier for the circuit connection and component fixation of the inductor, directly affecting the performance and stability of the inductor. In the manufacturing of inductors, different models and specifications of inductors have specific requirements for the size and shape of the PCB substrate. Therefore, the PCB substrate needs to be precisely cut to meet the production assembly standards and ensure that the subsequent production of the inductor can proceed smoothly. Traditional PCB substrate cutting techniques for inductors often suffer from inaccurate positioning and weak fixation when fixing the substrate, which can easily lead to substrate displacement during the cutting process. Furthermore, traditional cutting equipment is cumbersome and inflexible in adjusting the cutting position and angle, making it difficult to meet diverse cutting needs. These shortcomings not only reduce cutting accuracy, resulting in a large number of defective products and increasing production costs, but also potentially reduce production efficiency due to operational inconvenience, affecting the overall production progress of inductors. Therefore, we propose a PCB substrate cutting device for inductors. Utility Model Content

[0023] Working Principle: First, the PCB substrate 10 is placed and fixed. The PCB substrate 10 is placed on top of the rotary table 11. The positioning cylinder 18 at the top of the rotary table 11 passes through the PCB substrate 10, providing initial positioning. The cross-shaped fixing frame 7 is fixed to the top of the positioning cylinder 18 by bolts at its center. Fixing rods 8 are slidably installed at its four ends. The high-density springs 9 sleeved on the fixing rods 8 are respectively attached to the bottom of the four ends of the fixing frame 7 and the top of the positioning rubber pads 19 at the ends of the fixing rods 8. Under the elastic force of the high-density springs 9, the positioning rubber pads 19 are tightly attached to the PCB substrate 10, thereby firmly fixing the PCB substrate 10 on the rotary table 11. Next, the cutting position is adjusted. The cutting table 5 has fixed guide blocks at both ends. The end of the guide column 4 is placed inside the fixed guide block and forms a sliding fit. By pushing the guide column 4, it can slide along the fixed guide block, thereby driving the support bar 3 fixed on one side of the L-shaped structure at the top to move. At the same time, the output shaft of the small motor 13 installed inside the cutting table 5 is connected to the bottom of the rotary table 11. The connecting cylinder 16 at the center is connected, and the four symmetrical guide rail columns 15 at the top of the support plate 12 slide in the annular guide rail groove 17 at the bottom of the rotary table 11. The small motor 13 is started, which drives the rotary table 11 to rotate, thereby driving the PCB substrate 10 at the top to rotate, realizing the adjustment of the cutting angle. Then the cutting operation stage begins. After the cutting motor 2 is started, its output shaft drives the cutting blade 1 to rotate at high speed. At this time, the guide column 4 is pushed, so that the cutting blade 1 gradually approaches and contacts the PCB substrate 10 located below it, cutting the PCB substrate 10. During the cutting process, the protective frame 6 on the outer side of the top of the cutting table 5 can effectively block the debris generated during cutting, playing a protective role. The support leg at the bottom of the cutting table 5 provides stable support for the entire device. The support plate 12 is fixed to the top of the connecting ring 14 by bolts, providing a stable support foundation for the rotary table 11, ensuring that the rotary table 11 remains stable during rotation and cutting. Through fixing, adjusting position and cutting, the precise cutting operation of the PCB substrate 10 for inductor coils is completed.
