Supporting device and testing equipment

Abstract

The invention discloses a support device and detection equipment. The lifting mechanism includes: a chuck with a through hole; into the through hole of the chuck; the driving device includes a driving part and a transmission part, the driving part is used to generate power, and the transmission part is used to transmit the power to the lifting frame assembly; the driving part of the There is an included angle between the power output shaft and the moving direction of the lifting frame assembly. The lifting mechanism of the supporting device has a compact structure and a small longitudinal dimension, which is very favorable for space layout and connection or cooperation with other equipment.

Description

technical field [0001] The invention relates to the technical field of carrying, in particular to a lifting mechanism for lifting and lowering a sample during sample production or testing. The invention also relates to a support device and a detection device provided with the lifting mechanism. Background technique [0002] OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminescence Display (OELD). Due to the advantages of small thickness, light weight, better shock resistance, large viewing angle, short response time, higher luminous efficiency, the ability to manufacture on substrates of different materials, and flexible displays that can be made into bendable, etc., it has been widely used in many industries. It has been widely used in display equipment in the industry. [0003] At present, in the field of OLED substrate production and testing, with the improvement of the panel production process, the detection ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing lifting mechanisms are driven by a single air cylinder or hydraulic cylinder. Although the vertical lifting can be performed directly, since the air cylinder or hydraulic cylinder is vertically arranged below the fixed plate, the longitudinal dimension L of the lifting mechanism is the distance from the fixed plate to the top equipment. The distance L1 plus the length L2 of the air cylinder or hydraulic cylinder itself, that is, L=L1+L2, the excessively long longitudinal dimension causes the structure of the lifting mechanism to be not compact enough, which is not conducive to the space layout and the connection or cooperation with other equipment

[0005] In addition, the accuracy of the up and down movement of the control platform of the air cylinder or hydraulic cylinder is relatively low. In the case of a large number of ejector pins, it is difficult for a single air cylinder or hydraulic cylinder to transmit the force evenly to all ejector pins. If additional air cylinders or hydraulic cylinders, there will be a problem that multiple cylinders or hydraulic cylinders are difficult to operate synchronously

[0006] In addition, the load of the driving mechanism is relatively large. In the case of a large load, the moment of inertia of the lifting mechanism must be relatively large, resulting in poor stability, consistency and precision of the movement of the platform after carrying the OLED substrate, which is becoming more and more difficult. Meet the requirements of high-precision production and testing
