Technical Field

[0002] Flexible transistors, as a kind of electronic device with bending ability, play an important role in many fields. Flexible transistors are made of flexible materials, have good bending and ductility, can adapt to surfaces of various complex shapes, and bring more possibilities to the design and manufacture of electronic devices. They not only have high performance, but also have the characteristics of low power consumption. Due to the use of flexible materials, electronic devices made of flexible transistors are often lighter and more portable, which improves the convenience of carrying and use for users.

[0003] As a good flexible material, hydrogel materials are widely used in the preparation of flexible transistors. Flexible transistors prepared using hydrogels are not only simple to prepare, but also can make the gate, source, and base materials adhere together naturally through the interface heterojunction effect, greatly simplifying the assembly process. As a type of flexible electronics, while taking into account electrical properties, mechanical properties cannot be ignored. However, as a relatively new technology, there is no equipment specifically for the preparation of hydrogel transistors, and the prepared hydrogel transistors need to be tested by a tensile machine to test the firmness of the adhesion of the assembly interface. There is an urgent need for a device that integrates the functions of preparation and testing the quality of assembly.

[0004] Based on the above problems, the present invention proposes an integrated device for preparing and testing flexible NPN transistors, which includes a preparation module and a detection module; the preparation module includes a support rod, a base, a movable nut rack, a flange-type linear bearing, an end support rack, a movable support crossbar, a ball screw type slide module, an I-beam, a movable fixed rack, a two-phase hybrid stepping screw motor, a multi-functional baffle rack, a material bottle, a screw connecting block, a swinging air claw, and a flexible connecting rack; the module is used to flexibly prepare, cast, and bond two N-type materials and one P-type material of NPN transistors, and the resulting finished flexible NPN transistor is used for the subsequent interface bonding test of the detection module; the detection module includes a cylinder rack, a rod end flange-type cylinder, a molding mold pull rod, a slide seat, a linear slide rail, a mold rubber, a displacement mechanical sensor, a lifting and rotating platform, and a cam divider; the module cooperates with the rod end flange-type cylinder and the molding mold pull rod to gradually stretch the finished flexible NPN transistor until it breaks, and the quantitative values ​​of the entire process can be recorded by the displacement mechanical sensor and transmitted to the computer end.

[0005] The above design realizes the characteristics of the present invention with integrated preparation and detection. One device realizes the functions of preparation and detection of flexible transistors, filling the gap of such equipment at present. As a kind of flexible electronics, while taking into account the electrical properties, the mechanical performance problem cannot be ignored. It solves the problem that existing flexible electronic devices only focus on preparation and ignore detection. The present invention has excellent application prospects in the field of flexible electronic device manufacturing and detection. Summary of the invention
