Referring to fig. 1 to 7, a deformation testing mechanism for a folding screen mobile phone according to an embodiment of the present utility model mainly includes a product fixture 300, a measuring device and a pushing assembly 500, where the product fixture 300 is provided with a clamping position for clamping and fixing a first screen body of a folding screen, and exposing a second screen body folded on the first screen body. The measuring device is arranged corresponding to the clamping position and is used for measuring the displacement of the second screen body relative to the first screen body. The pushing assembly 500 can perform three-dimensional movement adjustment relative to the product fixture 300, and is used for docking the second screen body and driving the second screen body to move relative to the first screen body. It will be appreciated that the pushing assembly 500 simply applies a force to the second screen such that the second screen moves relative to the first screen with the mating gap of the hinge, and thus the measuring device may be fixedly disposed directly on the product fixture 300 so as to remain relatively fixed with respect to the first screen. The device can also be fixed by a peripheral, and can be flexibly set by a person skilled in the art according to factors such as actual structure, installation size requirement and the like.

It can be appreciated that the folding screen mobile phone deformation testing mechanism adopting the structure can utilize the product fixture 300 to clamp and fix the first screen body of the folding screen mobile phone, and simultaneously expose the second screen body, and then utilize the pushing component 500 to carry out three-dimensional movement adjustment relative to the product fixture 300, so that the pushing component can push against any side of the second screen body, and the second screen body can generate displacement relative to the first screen body, and then the deformation amount of the folding screen mobile phone caused by the fit clearance of the hinge can be judged through the measurement of the measuring device to be in the error range. Because the product fixture 300 only clamps the first screen body and exposes the second screen body, the pushing assembly 500 can apply force to the second screen body front and back and also can apply force left and right, so that the universality is stronger.

In some embodiments of the present utility model, the product fixture 300 is provided with a fixture base 305, a pair of positioning parts and a clamping part 304, wherein the fixture base 305 is horizontally arranged, and an upper end surface thereof is provided with a supporting block 306 and a supporting column 307, so that a supporting surface matched with the back surface of the first screen body (i.e. the end surface facing away from the second screen body) is formed by the supporting block 306 and the supporting column 307. It should be noted that, due to the different modeling designs of the smart phone and the parameter design reasons such as the camera, the back of the first screen body may have uneven conditions, and through the collocation design of the supporting block 306 and the supporting column 307, the first screen body can be well and stably supported, and the raised part of the first screen body can be avoided, or the high and low supporting points adapted to the raised part are formed. The locating part sets up the up end at frock base 305, including first locating part 301 and second locating part 302, first locating part 301 and second locating part 302 are the right angle and distribute for the locating edge of two adjacent side location of first screen body is formed to the back-up surface. It can be understood that, since most folding screen mobile phones in the current market are rectangular, i.e. two sides of the mobile phone are right-angle sides, the first positioning portion 301 and the second positioning portion 302 are distributed at right angles. If the corresponding mobile phone side is not in a right-angle distribution side form, the positioning part can be flexibly adjusted according to actual conditions, and the mobile phone can be stably clamped and fixed only by being matched with the two clamping parts 304. The clamping portion 304 can be disposed on the tooling base 305 near or far from the positioning portion, and is used for clamping the first screen body in cooperation with the positioning portion. Referring to fig. 7, the clamping part 304 is provided with only one corresponding to the first positioning part 301, and when the folding screen mobile phone is put on the supporting surface in practical application, the folding screen mobile phone is abutted against the first positioning part 301 and the second positioning part 302 to realize positioning alignment of azimuth, and then the folding screen mobile phone is clamped from the narrow side opposite to the first positioning part 301 through the clamping part 304. Because the rub test of the mobile phone is not stressed much, the clamping of the clamping part 304 by matching with the positioning part can be performed smoothly. Obviously, a plurality of clamping portions 304 may be provided, and those skilled in the art can flexibly set the clamping portions as required.

Further, in order to avoid the first screen body from falling out in the clamping process, the frame of the first screen body or the folding screen mobile phone is also prevented from being damaged, and the close ends of the positioning part and the clamping part 304 are detachably provided with an anti-slip chuck matched with the first screen body. The anti-slip chuck is made of plastic materials. When the side edge of the first screen body is provided with the radian along the thickness direction, the concave position with the same radian can be arranged, or the contact points on the two sides of the first screen body can be horizontally opposite or oppositely downward to the clamping acting force direction of the first screen body, so that the upward pushing acting force on the first screen body is avoided.

In addition, the support column 307 and the support block 306 may be made of the same material to increase friction with the first screen.

Referring to fig. 7, in some embodiments of the present utility model, a plurality of mounting holes are formed in the tooling base 305, and the support blocks 306 and the support columns 307 are detachably disposed in the mounting holes. Thus, the position adjustment can be realized by installing the supporting blocks 306 and the supporting columns 307 in different installation hole positions, so that the mobile phone with the folding screen or the mobile phone screen can be stably supported, and the interference position can be avoided. And specifically, the supporting block 306 and the supporting column 307 are matched with the installation hole site through screws to realize fixation, and the height adjustment can be performed by utilizing the screws, so that the mobile phone can be used for adapting to folding screen mobile phones with different shape designs and appearance designs, and also can adapt to folding screen mobile phones with different thicknesses, so that the second screen body protrudes upwards to be positioned in the measuring range of the measuring device and is convenient for pushing the range of the action of the assembly 500.

Referring to fig. 5 to 7, in some embodiments of the present utility model, the measuring device includes a laser ranging sensor 303 provided at an upper end of the positioning portion. Specifically, an angle code is disposed on the outer sides of the first positioning portion 301 and the second positioning portion 302 (i.e. in the direction away from the folding screen mobile phone), and the angle code is used to form a mounting position higher than the first positioning portion 301 and the second positioning portion 302 on the outer sides of the first positioning portion 301 and the second positioning portion 302, and the laser ranging sensor 303 is disposed at the mounting position.

Referring to fig. 2 to 4, in some embodiments of the present utility model, a folding screen mobile phone deformation testing mechanism is provided with a table top 100, on which a first horizontal linear guide 200 and a second horizontal linear guide 400 erected above the first horizontal linear guide 200 by a gantry 101 structure are provided on the table top 100.

The lifting seat 503 is slidably arranged on the adjusting seat 502 through a vertical guiding structure and is controlled by the transplanting cylinder 504. The force application part is arranged at the lower end of the lifting seat 503 through a three-axis pressure sensor 505 and is used for applying force to the second screen body. By adopting the structural arrangement of the embodiment, the force application part can realize two-stage lifting adjustment, and the three-dimensional movement adjustment of the force application part and the product tool 300 is realized by matching with the movement in the X, Y direction.

The force application part can be of a rigid structure, force application pushing is carried out on the side edge of the second screen body through three-dimensional movement adjustment, or a sucker structure is adopted, and the second screen body is sucked through three-dimensional movement adjustment and then horizontal acting force is applied.
