Universal type electronic screen positioning carrier

Abstract

The invention discloses a universal type electronic screen positioning carrier. The universal type electronic screen positioning carrier comprises a carrying plate. A supporting boss used for supporting a to-be-tested electric screen and a limiting structure used for positioning the to-be-tested electric screen are arranged on one lateral surface of the carrying plate. The limiting structure is arranged at periphery of the supporting boss. The limiting structure comprises a guide groove formed in the surface of the carrying plate and a limiting block connected into the guide groove in a sliding-fit mode. The limiting block is connected with the carrying plate by a positioning structure. Structure is simple and application is convenient. Application in positioning load bearing of electric screens with different sizes can be achieved without changing carrying plate overall.

Description

technical field [0001] The invention relates to an electronic screen carrier, which belongs to the technical field of testing non-standard products such as electronic screens, and in particular to a universal electronic screen positioning carrier. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of flat panel displays, liquid crystal electronic screens are widely used in the industry as a common product. Usually, after the production of LCD electronic screens is completed, the products need to be inspected. The detection method is generally that the operator installs the LCD electronic screen to be tested on the positioning carrier board, and then uses the PG test box to perform a lighting test on the LCD electronic screen. As a result, many positioning carriers for electronic screen lighting tests have been diffracted. [0003] Traditional positioning carrier boards are generally provided with grooves for ...

Problems solved by technology

[0003] Traditional positioning carrier boards are generally provided with grooves for positioning electronic screens on the carrier board. For example, Chinese invention patent CN106616317A discloses a FOG LCD screen Gamma tuning test fixture, which can not only perform lighting tests on LCD screens, but also Moreover, the inclination angle of the test table surface can also be adjusted according to the needs. At the same time, a positioning carrier plate with a split structure is recorded in the manual. “The positioning carrier plate of the Gamma tuning test fixture includes a connecting plate and a carrier plate; Detachable connection; the carrier board is connected to the surface of the connecting board, the surface of the carrier board is provided with a groove to accommodate and limit the LCD screen to be tested, and the surface of the carrier board is also provided with a guide groove; one end of the guide groove communicates with the groove, and the other end extends to the automatic guide The end of the pass-through device; the vacuum device is located at the bottom of the groove, and the liquid crystal screen to be tested is positioned and limited through the groove, and the FPC of the liquid crystal screen to be tested is guided to the clamping end of the automatic pass-through device through the guide groove; different sizes The LCD screen corresponds to a positioning carrier, and LCD screens of the same size are provided with corresponding guide grooves according to FPCs of different shapes. Large and small LCD screens require separate design of positioning carriers of different shapes, which is not universal and increases design, manufacturing and processing costs; 2. The positioning carrier adopts a split structure of connecting plate and carrier, which is not conducive to manufacturing and assembly ; 3. The part of the positioning carrier used to install and position the LCD screen is a groove structure, which not only requires high processing accuracy, but also is not easy to pick and place the LCD screen
