Generally, the liquid crystal panel 400 has a rectangular parallelepiped structure. Thus, the test support region is a rectangular parallelepiped recess region that conforms to the peripheral edge of the liquid crystal panel 400. Meanwhile, each limiting fixing part comprises a first limiting block 305 and a second limiting block 306, the first limiting block 305 and the second limiting block 306 are perpendicular to each other, and the first limiting block 305 and the second limiting block 306 can be attached to the adjacent corner edges of the liquid crystal screen 400 respectively. For example, in an embodiment of the present invention, the height values of the first stopper 305 and the second stopper 306 are both greater than the maximum height value of the elastic supporting component 200. From this, can guarantee that LCD screen 400 can be blocked and arrange in the test support region, and then further promote the support stability of touch-sensitive screen display module.
It should be noted here that, for the number of the elastic supporting components 200, the present invention is not limited at all, and the number of the elastic supporting components 200 can be adjusted according to actual requirements.
In addition, the present invention does not limit the connection mode between the first stopper 305 and the second stopper 306 and the base 100. For example, in one embodiment of the present invention, the first stopper 305 and the second stopper 306 are detachably mounted on the base 100. For example, a plurality of stopper mounting holes may be provided on the base 100. According to the specific size of the touch screen display module, the installation positions of the first limiting block 305 and the second limiting block 306 can be flexibly adjusted. Therefore, the universality of the testing device can be improved.
In one embodiment of the present invention, the elastic support assembly 200 includes a first spring and a support block. One end of the first spring is connected to the base 100. The other end of the first spring is connected with a supporting block for supporting the liquid crystal panel 400, and/or the elastic supporting member 200 is detachably connected to the base 100. Similarly, the installation position and the installation number of the elastic support assembly 200 can be flexibly adjusted according to the specific size of the touch screen display module.
In the use process, the back of the touch screen display module is placed on the supporting blocks at the upper ends of the first springs. Under the action of gravity of the touch screen display module, the first spring is downwards extruded by the fixing support, the control clamping plate and other components on the back of the liquid crystal screen 400 until the touch screen display module and the first spring are in a force balance state. The first spring can provide supporting force for the fixed support, the control clamping plate, the liquid crystal screen 400 and the like. Therefore, the touch screen display module is stably supported on the supporting blocks.
In another embodiment of the present invention, the elastic support assembly 200 includes a fixed guide rod 201, a telescopic guide rod 202, a stopper 203, a second spring 204, and a support block 205. The stopper 203 is provided at an inner end of the telescopic guide rod 202.
Wherein, the inside of the fixed guide rod 201 is formed with an accommodating cavity. The inner end portion of the telescopic guide rod 202 protrudes into the accommodation cavity and can move along the central axis of the accommodation cavity. The position-limiting part 203 can be limited at the inner side of the accommodating cavity. One end of the second spring 204 is connected to the inner bottom of the receiving cavity. The other end of the second spring 204 is connected to the inner end of the telescopic guide rod 202. A supporting block 205 for supporting the liquid crystal panel 400 is connected to an outer end portion of the telescopic guide bar 202.
Further, in an embodiment of the present invention, a threaded hole 101 is formed on the base 100. The lower end of the fixed guide rod 201 is formed with a screw coupling portion 206 fitted into the screw hole 101. The fixed guide rod 201 is fitted into the screw hole 101 through a screw connection portion 206.
Specifically, as shown in fig. 8 and 11, the lower end of the fixing guide rod 201 is screwed into the screw hole 101 connected to the base 100 by the screw connection portion 206. The fixed guide rod 201 is formed at the inside thereof with a hollow chamber, i.e., an accommodation chamber. The lower tip of flexible guide bar 202 wears to establish to the holding cavity of fixed guide bar 201 from top to bottom in, and flexible guide bar 202 can reciprocate along the central axis that holds the cavity. The lower end part of the telescopic guide rod 202 is further provided with a limiting part 203, and the limiting part 203 is located in the accommodating cavity and can be limited at the inner side of the accommodating cavity. This prevents the telescopic guide rod 202 and the fixed guide rod 201 from being separated from each other. A second spring 204 is further installed in the accommodating cavity, one end of the second spring 204 is connected with the inner bottom of the accommodating cavity, and the other end of the second spring 204 is connected with the lower end of the telescopic guide rod 202. Similarly, a support block 205 is provided at the upper end of the telescopic guide rod 202.
In the using process, the back of the touch screen display module is placed on the supporting block 205 at the upper end of each telescopic guide rod 202. Under the action of gravity of the touch screen display module, the fixing support and the control clamping plate located on the back of the liquid crystal screen 400 downwards extrude the telescopic guide rod 202, and the telescopic guide rod 202 downwards moves along the central axis of the accommodating cavity of the fixing guide rod 201 and compresses the second spring 204 until the touch screen display module and the second spring 204 are in a force balance state. The second spring 204 can provide a supporting force for the fixing bracket, the control panel and the liquid crystal screen 400. Therefore, the touch screen display module is stably supported on each supporting block 205.
In one embodiment of the present invention, a flexible protective layer 500 is disposed on the support block 205.
Through set up flexible protective layer 500 on supporting shoe 205, can effectively prevent among the test procedure fish tail touch-sensitive screen display module.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
