Portable angle-adjustable type electronic screen test fixture

Abstract

The invention discloses a portable angle-adjustable type electronic screen test fixture. The portable angle-adjustable type electronic screen test fixture comprises a mounting seat and a rack, whereinthe rack is hinged with the mounting seat through a hinged shaft; an angle adjusting device is arranged between the mounting seat and the rack; a PG test box, a carrier and a POGO conduction device are arranged on the rack; the PG test box is electrically connected with the POGO conduction device; the carrier is of an integrated plate-shaped structure; a support boss and limiting structures are arranged on one side surface of the carrier; the limiting structures are arranged on the periphery of the support boss; each limiting structure comprises a guiding groove formed in the surface of the carrier and a limiting block connected into the guiding groove in a sliding fit manner, and the limiting block is connected with the carrier through a positioning structure. The fixture is simple in structure and convenient to carry, and can be applicable to lighting tests of electronic screens with various sizes on the premise that the carrier is not replaced integrally.

Description

technical field [0001] The invention relates to a portable electronic screen test fixture, which belongs to the technical field of testing non-standard products such as electronic screens, in particular to a portable electronic screen test fixture with adjustable angle. 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. Generally, after the production of LCD electronic screens is completed, the product needs to be tested. The detection method is generally that the operator manually connects the electrical part of the LCD electronic screen to be tested, and then uses the PG test box to perform a lighting test on the LCD electronic screen. Diffraction produced a lot of electronic screen lighting test fixtures. For example, Chinese patent CN106646947A discloses a FOG liquid crystal screen Gamma tuning t...

Problems solved by technology

For example, Chinese patent CN106646947A discloses a FOG liquid crystal screen Gamma tuning test fixture, which can not only perform a lighting test on the liquid crystal screen, but also adjust the inclination angle of the test table as required. The positioning carrier of the structure "The positioning carrier of the Gamma tuning test fixture includes a connecting plate and a carrier plate; the connecting plate is detachably connected to the surface of the work table; the carrier plate is connected to the surface of the connecting plate, and the surface of the carrier plate is provided with accommodation restrictions The groove of the LCD screen, 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 end of the automatic conduction device; the vacuum device is located at the bottom of the groove, and the liquid crystal screen to be tested is positioned through the groove and limit, guide the FPC of the LCD screen to be tested to the clamping end of the automatic conduction device through the guide groove; LCD screens of different sizes correspond to a positioning carrier, and LCD screens of the same size are set according to FPCs of different shapes. The technical solution of the above-mentioned positioning carrier has the following disadvantages: 1. The positioning carrier is a special carrier, and LCD screens of different sizes need to separately design positioning carriers of different shapes, which does not have versatility. Increased design, manufacturing and processing costs; 2. The positioning carrier adopts a split structure of the connecting plate and the carrier plate, 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, Not only does it require high machining accuracy, but it is also inconvenient to pick and place the LCD screen.
