Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting device for microphone diaphragms. Background Art
[0002] The microphone diaphragm is an important component in a microphone. It is usually made of a thin elastic material and can vibrate in response to changes in external signals or forces. When sound waves reach the microphone, the diaphragm will vibrate accordingly and convert the mechanical vibration of the sound waves into electrical signals. The material of the diaphragm is usually required to have good elasticity and light weight characteristics to ensure that it can quickly respond to external signal changes. A laser cutting machine is a device that uses a high-energy laser beam to cut materials. It focuses the laser beam generated by the laser onto a small cutting point and cuts or ablates the material through the action of high temperature. During the production process of the diaphragm, a laser cutting machine is needed to cut the diaphragm into a specific shape. However, the traditional laser cutting machine cannot adjust the diameter of the fixing ring according to different requirements when cutting the diaphragm, which makes the diaphragm prone to displacement, resulting in inaccurate cutting positioning and uneven cutting surfaces. Moreover, when the fixing ring positions the diaphragm, if the pressure is too large, it is easy to cause damage to the diaphragm. Therefore, it needs to be improved. Content of the Utility Model

At the same time, the limit of the knob 31 facilitates the maintenance work of the cutting table 11.
[0030] Working principle: In the process of using the cutting diaphragm, firstly, the whole diaphragm needs to be placed on the cutting table 11, and then the first motor 4 drives the first threaded rod 5 to rotate, so that the first threaded rod 5 drives the support frame 3 and the laser 6 to move horizontally and vertically, and then the second electric telescopic rod 12 drives the fixing ring 13 to move, so that the fixing ring 13 drives the arc block 17 and the cushion block 20 to move, and the movement of the second electric telescopic rod 12 drives the spring 14 to be compressed, and then the compression of the spring 14 will buffer the movement of the fixing ring 13, and then the cushion block 20 will press on the diaphragm to complete its positioning, and the cushion block 20 and the spring 14 can prevent the fixing ring 13 from causing pressure loss to the diaphragm, and then the laser beam is transmitted to the laser 6. The cutting head 9 is located at the cutting head 9, and the laser beam is irradiated to the surface of the diaphragm through the cutting head 9, and then the diaphragm is quickly heated and melted by the high temperature of the laser, and the second motor 7 drives the rotating rod 8 and the cutting head 9 to rotate to form a circular cutting path, thereby completing the cutting work of the diaphragm. When it is necessary to cut diaphragms of different diameters, the second threaded rod 16 can be driven to move by the turning handle 18, and then the arc block 17 is driven to move by the second threaded rod 16, and the moving path of the arc block 17 is limited by the limiting rod 15. At the same time, the arc block 17 is retracted or opened to drive the connecting block 19 to move on the inner surface of the other side thereof, so that the arc block 17 and the cushion block 20 can locate diaphragms of different diameters, and the cutting head 9 is driven to move by the first electric telescopic rod 10. The cutting head 9 can be moved to a suitable position so that the cutting head 9 can cut diaphragms of different diameters, thereby increasing the applicability of the laser cutting machine. When the pad 20 is severely worn and needs to be replaced, the fixed block 21 can be removed from the arc block 17, so that the magnetic block 22 on the fixed block 21 is separated from the magnetic block 22 on the arc block 17, and the plug 23 is driven out of the slot by the fixed block 21, and then the pad 20 can be removed from the T-slot for replacement. Similarly, the fixed block 21 can be limited by the magnetic block 22, and the fixed block 21 can be auxiliary limited by the plug 23, thereby improving the stability of the fixed block 21. Then, the position of the pad 20 can be limited by the fixed block 21. After the diaphragm cutting is completed, the third threaded rod 27 needs to be driven by the third motor 28 is rotated, and then the baffle 25 is driven by the third threaded rod 28 to move on the inner side of the storage groove 24, so that the baffle 25 moves to the placement plate 26, and then the cut diaphragm will fall onto the buffer pad of the collection box 29 through the through hole on the cutting table 11, and then the baffle 25 is moved back to its original position, and a new diaphragm is placed on the cutting table 11 for cutting, which provides convenience for the material collection of the laser cutting machine. When the cutting table 11 needs to be maintained, the knob 31 can be turned to turn the knob 31 away from the thread groove 32 of the fixing rod 30, and then the cutting table 11 can be removed from the fixing rod 30 for replacement. Conversely, the knob 31 can be fixed to the surface of the fixing rod 30 through the thread groove 32, thereby completing the position limit of the cutting table 11.It facilitates the maintenance work of the cutting table 11.,
