According to the above technical scheme, at first the utility model discloses a set up the relative mounting substrate of die cavity module into the modular structural style that can dismantle the change, can be to the display module assembly that awaits measuring of different structure sizes, the die cavity structure of display module assembly is put to fast switch over and transform, and fundamentally has solved current detection device and when detecting or circulate as the carrier on the detection line to different structure size display module assemblies, need be according to the detection device's of different structure styles of different product configurations and size problem. The modular design of the cavity module has the advantages that the cavity modules with different structural styles can be repeatedly used as accessories, the production cost is reduced, and the positioning of a new display module on the mounting substrate can be realized only by matching the corresponding cavity module according to the updating and updating of the display module.

In addition combine foretell modular design thinking, the utility model discloses still set up spacing module and crimping switch on the crimping module also relative mounting substrate in the subassembly into the modular structure of changing of dismantling, can accomplish the model switching of display module group location fixed part through switching die cavity module and spacing module to new display module group. In addition, the replacement of the crimping module in the crimping conduction assembly can complete the crimping conduction between the external equipment and the display module to be tested in different conduction modes.

Because the electrical connection end of the display module includes the FPC and the electrical connector located on the FPC, in order to facilitate the routing of the FPC and avoid the side wall portion of the cavity module from blocking the FPC in the routing stroke of the FPC, in a preferred embodiment, the side wall portion 21 of the cavity module 2 includes an avoidance notch 22 for the electrical connection end FPC of the display module to pass through.

To the utility model provides a relative mounting substrate of die cavity module sets up to the modularized structural design who can dismantle the change among the detection device, the utility model also provides a new spacing modular structure who uses with die cavity module cooperation, it is shown in combination figure 3, specifically, spacing module 5 includes:

In an embodiment, when the key 50 is pressed, the moving block 51 can move in a direction away from the cavity 4, and the key 50 and the moving block 51 need to be in a relative sliding connection, taking the embodiment shown in fig. 3 as an example, when the key 50 is pressed, the key 50 is pressed perpendicularly to the bearing surface of the mounting substrate 1 and transmits the pressing force to the moving block 51, and the moving block 51 can move in the direction away from the cavity 4 after being pressed, that is, the moving block 51 moves towards the outside of the cavity 4.

In other words, the pressing force applied to the key 50 is perpendicular to the moving direction of the moving block 51, and to achieve this technical effect, the sliding connection position between the key 50 and the moving block 51 should be set to be an inclined plane, i.e. at least one surface of the mating surface between the key 50 and the moving block 51 is set to be an inclined plane. From the perspective of force analysis, only when the sliding connection position between the key 50 and the motion block 51 is configured with an inclined surface, the pressing force perpendicular to the bearing surface of the mounting substrate 1 can be converted into an urging force of the motion block 51 moving in the direction away from the cavity 4, and the configured inclined surface should be inclined with respect to the pressing force and the urging force; of course, it is possible to achieve the above effect by having a slope in one of both the key 50 and the motion block 51.
