Problems solved by technology

[0003] At present, in the LCD manufacturing industry, there is no clear definition of the maximum bearing capacity of the connection point of the lamp wire of the backlight module, and there is no practical test method, so that the bearing capacity of the lamp wire cannot be well obtained in the early design stage. Verification, which will cause trouble for subsequent operations

Abstract

The invention provides a testing method of maximum bearing force of connecting points of lamp wires of backlight module group, and the testing method includes the following steps: 1) fixing the backlight module group on a horizontal working table; 2) connecting the backlight module group and a power supplier, so that the backlight module group is lighted; 3) connecting a tension device and the wires; 4) exerting force in the extending direction of the wires with the tension device so as to increase the tension until the backlight module group dies out; and 5) taking the peak value recorded bythe tension device as the maximum bearing force of the connecting points of the wires of the backlight module group the instant the backlight module group dies out. The testing method can accurately determine the maximum bearing force of the connecting points of the wires of the backlight module group, has the advantages of reasonable design and simple operation, and provides a feasible method inthe field, thus shortening the later proving procedures and time.

Description

【Technical field】 [0001] The invention relates to a method for testing tensile force, in particular to a method for testing the maximum bearing force of connection points of wires of a backlight module. 【Background technique】 [0002] see figure 1 As shown, the backlight module 1 of the current LCD (liquid crystal display) usually includes a backlight module body 11, and the upper and lower edges of the backlight module body 11 are respectively provided with lamp tubes (not shown in the figure). One end of the lamp tube and the lower end lamp tube leads out a lamp wire 12 respectively, and the other end of the lamp wire 12 also has a joint 120 that can be connected to a power supply. Because the lamp wire 12 has a certain length, it is fixed on the on the backlight module body 11 . The connection point 15 between the lamp wire 12 and the lamp is usually formed by a solder joint. The bearing force of the solder joint and the lamp tube is weaker than the lamp wire 12 itself...
