Abstract

The invention relates to the technical field of display accessory testing devices, in particular to a CELL crimping cylinder friction unit. The unit comprises a fixing plate, the unit is fixedly mounted in one side of external equipment through the fixing plate; a to-be-detected workpiece is conveyed to a position right below the unit provided by the invention; a servo cylinder pushes a fixing frame to move downwards; when the lower surface of a pressure head makes contact with the upper surface of the to-be-detected workpiece, the servo cylinder is closed, a low-friction air cylinder is started, the low-friction air cylinder pushes a pressure sensor and a pressure head inclination fine-adjustment device to move downwards; a limiting rod moves downwards along a guide hole in the fixing frame; the limiting rod avoids excessive downward movement of the pressure head inclination fine adjustment device; the pressure sensor transmits the pressure to a controller in real time, so that the controller controls the pressure in the low-friction air cylinder, the pressure value of the upper surface of the to-be-detected workpiece can be accurately controlled, the pressure value can be finelyadjusted conveniently, the test sensitivity is improved, and the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of display accessory testing devices, in particular to a CELL crimping cylinder friction unit. Background technique [0002] In the mass production process of the existing display CELLs, each CELL needs to be crimped and bonded. After the alignment between CELL and FPC is completed, apply appropriate pressure through the pressure head to crimp the point screen. The pressure exerted on the pressure head is judged by controlling the pressure regulating valve of the cylinder, and the pressure of the cylinder is applied to the pressure head. During the expansion and contraction process of ordinary cylinders, the friction force of the internal piston is large, which makes the pressure unstable and the pressure fluctuations are large, and when the pressure test is performed, the minimum pressure value of the ordinary cylinder is relatively high, which is not conducive to the sensitivity test, and The inability to...
