A quick and flexible bonding and sealing machine for poct real-time detection chip products

Abstract

A POCT chip product fast flexible bonding sealing machine comprises a pressure cylinder (1), a pneumatic system, guide rods, a floating connector, a guide rod connecting plate, a flexible upper pressing plate, a rigid lower pressing plate, sliding sleeves, an upper plate, a rigid upper pressing plate, stand columns, a flexible lower pressing plate, a sensor connecting plate, a sensor and detecting system and a lower plate. The pneumatic system drives the pressure cylinder, a flexible upper pressing head moves downwards in the work process, and is in contact with a chip to provide pressure, sealing is completed, flexile design is adopted in the upper pressing head and a lower pressing head, and the problem that due to the fact that the chip is not flat or the pressing heads are not flat, sealing is difficult can be effectively solved in the sealing process. Self-adaption adjusting design is adopted in the upper pressing head, the straightness and perpendicularity of the upper pressing head are guaranteed, the lower pressing head is fixed with a weighing sensor, the centering performance of the lower pressing head and the upper pressing head is good, and the structure is simple. The quality and speed of bonding sealing can be effectively improved through the design of the whole machine, and a foundation is laid for bonding sealing automation.

Description

technical field [0001] The invention relates to a POCT instant detection chip product, which is a flexible bonding and sealing device used for the POCT instant detection chip. Background technique [0002] POCT refers to any test performed outside of a testing center by a hospital professional or non-professional, referred to as a point-of-care test. Compared with the traditional central laboratory testing, point of care testing (POCT) has the characteristics of rapid acquisition of experimental results, simplified operation, less sample consumption, and the use of whole blood samples. However, one of the key problems to be solved in the production of POCT based on a lab-on-a-chip is the sealing of the chip. Sealing is the sealing of the substrate and the cover to complete the production of the chip, which is a key technology of microsystem packaging. Poor sealing quality can easily lead to chip leakage, can not be sealed, and also affect the appearance of the chip. Theref...

AI Technical Summary

Problems solved by technology

First of all, the chip is prone to defects, the sealing is not complete, and the chip is prone to bubbles locally, which affects the sealing of the chip. As the sealing pressure increases, the microstructure array is easily deformed or even crushed.

Secondly, the degree of automation is low. Most of the current POCT real-time detection chip products that are glued and sealed are sealed manually, which takes a long time and has poor sealing effect.
