A production equipment for dome sheet processing and springback force detection function

Abstract

The invention discloses a production equipment for DOME sheet processing and springback strength detection, relates to the technical field of electronic parts processing and detection, and is specifically a special-shaped film cutting and positioning glue dispensing mechanism, a rotating clamping mechanism, and an automatic holding device for negative pressure conveying. Pressing mechanism, shrapnel resilience and life detection mechanism and monitoring and recording mechanism, the bottom of the special-shaped film cutting and positioning dispensing mechanism is provided with a rotating clamping mechanism, and the top of the contact bump is provided with a power supply element. In the production equipment of DOME sheet processing and springback force detection function, the height and fatigue of the shrapnel are tested with a simple mechanical mechanism under the condition of controllable stroke. The user can control the circular cam speed through the second motor to achieve control. The purpose of the lifting frame stroke, the setting of the monitoring and recording mechanism enables the rebound height of the shrapnel to be accurately recorded and fed back in each pressing stroke, so as to make targeted adjustments to the stress and strength of the shrapnel, process design, and more applicability powerful.

Description

technical field [0001] The invention relates to the technical field of processing and detection of electronic parts, in particular to a production equipment for DOME sheet processing and springback strength detection. Background technique [0002] Mobile phone Dome (Metal dome Switch), which is a PET sheet containing metal shrapnel (dome), used as a switch on circuit boards such as PCB or FPC, plays an important touch between the user and the instrument The role of the type switch, the metal shrapnel on the membrane button is located on the conductive part of the PCB (mostly located above the gold finger on the circuit board), when pressed, the center point of the shrapnel is concave and touches the circuit on the PCB, Thus a loop is formed, the current passes through, and the whole product can work normally. [0003] The existing DOME film processing and testing equipment, common problems are: limited by the existing manufacturing process level, the assembly of mobile phon...

Problems solved by technology

[0003] The existing DOME film processing and testing equipment, common problems are: limited by the existing manufacturing process level, the assembly of mobile phone DOME film is mostly done by hand, and due to the different shape of the carrier circuit board, it is usually required that the PET sheet has a non-standard size after cutting And the position of the shrapnel (dome) is positioned and dispensed. This process is too cumbersome for manual operation and the accuracy is difficult to guarantee. The production efficiency is low. The strength and height error of the shrapnel (dome) will affect the quality of the finished product, which will lead to problems such as loud noise, bad pressing feel, and short life of the assembled product.
