Platform trim device and trim method of spider web type hot press based on modal drive

Abstract

The invention provides a mode-driven spider web type heat press platform trim device and a trim method thereof, which include a spider web type trim module and a platform monitoring module. Its trim module includes a spider web structure device, a piezoelectric ceramic sheet, a fixed block, and a modal drive device. The trimming of the platform is realized through the displacement adjustment of the modal-driven spider structure. The platform observation module includes a laser ranging device. Signal processing is performed by four sets of laser sensors for real-time monitoring of the platform position. Through the processing of four sets of data, it is judged whether the platform is balanced. The platform alignment device designed by the invention can perform precise trimming under the condition of micron level, and because of the modal drive mode, the trimming device can be simplified without the traditional stopping device. The complexity of the mechanical structure is greatly reduced. It has the advantages of small size, high working precision and simple structure and device. Applicable to micron-level platform trim requirements.

Description

technical field [0001] The invention relates to the field of hot press platform trimming, in particular to a platform trimming device and a trimming method before the hot press platform works. It belongs to the technical field of micro-assembly and micro-operation. Background technique [0002] In modern industrial production, the heat press itself is an indispensable part. Different from traditional industrial production, in the field of microfluidic chip production, hot presses have gradually played a very important role. Due to the great potential of microfluidic chip technology in the fields of biology, chemistry, and medicine, it has developed It has become a new research field interdisciplinary of biology, chemistry, medicine, fluid, electronics, materials, machinery and other disciplines. An important manufacturing method of microfluidic chips is hot pressing. One of the most important equipment is the high-performance heat press. The production capacity of the he...

Problems solved by technology

Since the upper and lower sides of the existing hard pressure plate are difficult to achieve absolute balance, it will cause uneven pressure on the upper and lower surfaces of the chip, resulting in the collapse or excessive deformation of the internal microstructure of the chip

Due to the sharp change of temperature and the existence of microstructure, it will cause the micro-warping of the chip, and the uneven thickness of the chip or the micro-warping will lead to the uneven pressure applied on the top and bottom of the chip by the pressing method, so that This leads to uneven bonding of the chip. After the temperature reaches the softening point of the plastic, it will lead to a large collapse of the internal microstructure of the chip or excessive deformation and blockage, making the obtained chip unusable.
