Description

Technical Field

[0001] This application relates to the field of laser marking and positioning fixture technology, and in particular to a multilayer diaphragm microporous laser marking and positioning fixture. Background Technology

[0002] With the rapid development of microelectronics technology and acoustic devices, multilayer diaphragms, as the core vibrating components of precision acoustic elements such as miniature loudspeakers and microphones, have their processing precision directly determining the performance stability of acoustic devices.

[0003] In the manufacturing process of multilayer diaphragms, laser marking technology is widely used for marking and parameter engraving on the diaphragm surface due to its non-contact, high precision, and high efficiency. Conventional laser marking equipment mostly uses rigid fixtures to fix the workpiece, but under the impact of high-frequency laser and the vibration of the equipment during operation, multilayer diaphragms are prone to micron-level displacement, resulting in inaccurate marking positions.

[0004] Existing fixing clamps mostly achieve fixation through metal claws or vacuum adsorption. On the one hand, the concentrated contact pressure can easily cause indentations or micro-cracks on the edge of the diaphragm. On the other hand, uneven distribution of negative pressure can easily lead to local stretching and deformation of the diaphragm.

[0005] In other words, existing technologies have the following technical problems: ordinary laser marking and positioning equipment is prone to deformation and damage when limiting multi-layer diaphragms. Therefore, a multi-layer diaphragm micro-perforated laser marking and positioning fixture is proposed to address the above problems. Summary of the Invention

Through this technical solution, the operation of the servo motor A205 can drive the threaded rod 204 to rotate, and the rotation of the servo motor A205 can drive the threaded rod 204 to rotate, thereby driving the movable seat 203 to move, realizing the function of lateral movement and position adjustment. The support plate A206 is fixed to the side wall of the movable seat 203. One end of the support guide rod 208 is fixedly connected to one side of the support plate A206, and the other end of the support guide rod 208 is fixedly connected to the support plate B207.

A laser marking machine 210 is fixedly connected to the bottom surface of the movable frame 209.

[0041] The diaphragm fixing assembly 3 includes a supporting circular plate 301, a fixing collar 302, an annular airbag 303, a fixing cylinder 304, a connecting pipe 305, a moving piston 306, and a moving guide rod 307.

The other end of the connecting pipe 305 extends into the inner cavity of the annular airbag 303 and is fixedly connected to the annular airbag 303. Through this technical solution, the multi-layer diaphragm 4 that needs to be limited and fixed is set at the inner side of the annular airbag 303. By controlling the contraction of the cylinder 308, the supporting circular plate 301 is moved downward, thereby driving the fixed cylinder 304 to move downward. This causes the moving piston 306 to move upward in the inner cavity of the fixed cylinder 304, so that the gas in the inner cavity of the fixed cylinder 304 enters the inner cavity of the annular airbag 303 through the connecting pipe 305, thereby causing the annular airbag 303 to expand. The expanded annular airbag 303 can clamp and limit the side of the multi-layer diaphragm 4, thus achieving the function of limiting and fixing. At the same time, while limiting the multi-layer diaphragm 4, damage caused by hard contact is avoided.
