Problems solved by technology
The crimping actuators of the current display screen testing fixtures include the following types: elbow clamps (or similar components), cylinders, electric cylinders, etc., all of which are rigid crimping, relying on artificial force or the use of thrust Components, this is easy to cause crimping damage to the product, to different degrees of damage to the product test point (PAD point) or to the test probe, it is easy to cause accidents such as the operator's hand being pressed, and the actuators such as cylinders and electric cylinders During the operation, the noise generated is relatively large and the movement is relatively cumbersome. Therefore, the existing display fixtures cannot meet the test requirements.

Embodiment Construction
[0022] In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the drawings that need to be used in the description of the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other obvious deformation modes according to these drawings without paying creative efforts.
[0023] exist figure 1 Among them, it is a schematic diagram of the structure of the precision test fixture for the display screen module, including a box body. A top plate 3 is provided on the upper end of the box body. There is an alignment mechanism, and an exhaust mechanism is provided on both sides of the crimping mechanism. The exhaust mechanism includes a protective plate 1, a fan 2, and an air source 7. The protective plate 1 is respectively arranged on both sides of the air source 7. The lower end of the...

The invention discloses a precision test fixture for a display screen module, which comprises a box body, a top plate, a placement platform, an alignment mechanism and a crimping mechanism. The top plate is installed on the box body, the placement platform and the crimping mechanism are installed on the upper end of the top plate, and the alignment mechanism is installed on the lower end of the top plate. The top plate is equipped with manual valves and buttons. The placement platform includes a placement plate and a pressure sensor. The pressure sensor is set at the lower end of the placement plate. The crimping mechanism includes a protection plate, a fan, an air source, and a pressure plate. There are two protection plates, which are respectively perpendicular to the two sides of the air source. The lower end of the protection plate is slotted and connected to the fan. The positioning mechanism includes air claws, and the air claws are arranged at the lower end of the top plate. The invention utilizes the flexible crimping of the wind to protect the product well, the crimping force can be precisely adjusted, the success rate and service life of the precision test fixture of the display screen module can be improved, and the noise in the use process can be reduced.
Description
technical field [0001] The invention relates to the technical field of display screen module detection, in particular to a display screen module precision test fixture. Background technique [0002] With the rapid development of display-related electronic products such as smartphones, tablet computers, notebooks, high-definition TVs, and smart watches, the market demand for display screen modules in the DISPLAY industry is also increasing rapidly. This also puts forward higher requirements on the product productivity and yield rate of display screen manufacturers. In the production process of the display screen, the inspection link also plays a very important role in the whole process, which is directly related to key factors such as the production speed, yield rate, and quality of the display screen. Its main function is to falsely press the flexible circuit board on the display screen for functional testing, that is, to press the flexible circuit board on the correspondin...
