Abstract

The invention provides a pulling force measuring device, and relates to a measuring device. An adhesive force between an FPC (Flexible Printed Circuit) and a cell of existing pulling force equipment, and an adhesive force between a TP (Touch Pad) and an LCM (Liquid Crystal Module) need to be independently measured through two sets of equipment, so that the layout area of the equipment is large, the construction cost of the equipment is relatively high, and a measuring process consumes more time and labor. The pulling force measuring device comprises a connecting block, an L-shaped block, a fastening part and two movable supporting rods; the two movable supporting rods are arranged at the bottom of the connecting block; the FPC is stored in a gap between the two movable supporting rods; a vertical section of the L-shaped block is detachably connected between the two movable supporting rods through the fastening part; a horizontal section of the L-shaped block is clung to the TP; a first through hole is formed in the vertical section of the L-shaped block along the thickness direction; each movable supporting rod comprises a clamping rod and a testing probe; the top end of each clamping rod is in sliding fit with the bottom of the connecting block; the corresponding testing probe is fixedly mounted at the bottom end of each clamping rod. The pulling force measuring device provided by the invention is used for testing the adhesive force.

Description

technical field [0001] The invention belongs to the field of mobile phone touch display, and in particular relates to a pulling force measuring device. Background technique [0002] In the field of mobile touch display, in order to ensure the long-term quality assurance of products, after the FPC Bonding and TP and LCM lamination processes are completed, use a tensile machine to test the adhesion between FPC and cell or the water glue OCA between TP and LCM The adhesion is tested, and FPC is a flexible circuit board, which is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. cell refers to the LCD box, and TP refers to the TouchPad touch screen. LCM is a liquid crystal display module, which includes LCD and display control chips, RAM, ROM, etc., and can be used directly after connecting to the mobile phone motherboard. [0003] The existing tension measuring equipment generally adopts the following two ...
