The two airbag columns are arranged in parallel at intervals on the arc-shaped curved surface. The airbag columns are communicated with the airbag plate through the air pipe.

[0008] Preferably, the limiting component includes a vertical plate and two guiding plates. The two guiding plates are horizontally arranged on both sides of the connecting column, the vertical plate is vertically arranged on the upper end surface of the base, a through hole matching the connecting column is arranged on the vertical plate, and guiding grooves are arranged at positions on the hole wall of the through hole corresponding to the guiding plates.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present invention.

[0025] In addition, if there are terms "first" and "second", they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise specifically defined.

[0026] In the present invention, unless otherwise clearly defined and limited, terms such as "assembled", "connected", and "joined" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may also be a mechanical connection; it may be directly connected, or connected through an intermediate medium, and may be internally connected and communicated between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] It should be understood that when used in this specification and the appended claims, the terms "comprises" and "comprising" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0028] It should also be understood that the terms used in the description of the embodiments of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0029] A specific embodiment of the present invention is shown in the accompanying drawings. An auxiliary positioning structure of a mobile phone screen defect detection device includes a base 1; it also includes two clamping components arranged on both sides of the upper end surface of the base 1;

[0030] The clamping component includes a U-shaped frame 5, a rotating positioning plate 8, a pressing plate 7, and a rotating rod. The U-shaped frame 5 is arranged on one side of the upper end surface of the base 1. The rotating positioning plate 8 is rotatably arranged at the upper end of the U-shaped frame 5 through a hinge shaft 6. The pressing plate 7 is vertically arranged at the upper end of the rotating positioning plate 8. A horizontal threaded through hole is provided at the lower end of the rotating positioning plate 8. An external thread matching the threaded through hole is provided on the outer circumferential surface of the rotating rod. The rotating rod is rotatably arranged in the threaded through hole.

[0031] As a further improvement of this embodiment, it also includes a buffer component. The buffer component includes an airbag plate 12, a connecting column 18, a piston 22, and a limiting component. The shape of the airbag plate 12 is adapted to the shape of the side of the mobile phone screen 9. The connecting column 18 is arranged on one side of the airbag plate 12. An axial piston hole 19 is provided on the connecting column 18. The piston hole 19 is internally communicated with the airbag plate 12. The piston 22 is arranged at one end of the rotating rod and cooperates with the piston hole 19. The limiting component is used to limit the rotation of the connecting column 18.

[0032] Further, the buffer assembly further includes an air tube 14 and two airbag columns 11. The position where the pressing plate 7 contacts the mobile phone screen 9 is an arc-shaped curved surface 10. The two airbag columns 11 are arranged in parallel at intervals on the arc-shaped curved surface 10. The airbag columns 11 are communicated with the airbag plate 12 through the air tube 14.

[0033] As is well known, the mobile phone screen is a relatively easily damaged component of the mobile phone. During the detection process, if it is not fixed properly, the mobile phone screen is prone to damage. In the solution of the present invention, when the mobile phone screen is fixed, the rotating shaft is rotated. The rotating shaft drives the piston to move in the piston hole towards the airbag plate, squeezing the air in the piston hole so that the air in the piston hole enters the airbag plate. After the airbag plate is inflated, the surface of the airbag plate is in full contact with the side of the mobile phone screen, realizing the horizontal limit of the mobile phone screen. In this process, a small part of the gas in the airbag plate enters the two airbag columns on the pressing plate through the air tube. After the airbag columns are inflated, they contact the upper end surface of the mobile phone screen, thereby realizing the vertical limit of the mobile phone screen.

[0034] It should be noted that if inflatable components such as airbags are always in a fully inflated state, they are prone to air leakage under the action of internal air pressure, resulting in the failure of the airbags. In the solution of the present invention, the piston extrusion inflation method is adopted. After the mobile phone screen is fixed, the rotating shaft is rotated to make the piston move away from the airbag plate. At this time, the airbag plate and the airbag columns are no longer in a fully inflated state, but there is still a part of the gas inside. In this way, the internal air pressure of the airbag plate and the airbag columns is reduced, improving the service life of the airbag plate and the airbag columns. Moreover, compared with some commonly used buffer components such as soft pads, the airbag can undergo a greater deformation during buffering, so the buffering effect is better.

[0035] The present invention can realize the horizontal and vertical limits of the mobile phone screen by rotating the rotating shaft, which is more convenient to clamp and has a better positioning effect. At the same time, by rotating the rotating shaft, the inflation of the airbag plate and the airbag columns can be realized, providing buffering during the clamping process to prevent the mobile phone screen from being damaged due to hard contact between the traditional fixing device and the mobile phone screen.

[0036] Moreover, the position where the pressing plate 7 in the solution of the present invention contacts the mobile phone screen 9 is set as an arc-shaped curved surface, so that after the pressing plate rotates a certain angle, both airbag columns can contact the mobile phone screen.

[0037] Further, the limiting component includes a vertical plate 13 and two guiding plates 17. The two guiding plates 17 are horizontally arranged on both sides of the connecting column 18. The vertical plate 13 is vertically arranged on the upper end surface of the base 1. A through hole 26 matching the connecting column 18 is provided on the vertical plate 13, and guiding grooves 27 are provided at positions corresponding to the guiding plates 17 on the pore wall of the through hole 26. The cooperation between the guiding grooves and the guiding plates can prevent the connecting column from rotating during movement.

[0038] Among them, it should be noted that in order to prevent the piston from rotating in the piston hole, a clamping groove is provided on the pore wall of the piston hole, and a limiting edge corresponding to the clamping groove is provided on the circumferential surface of the piston. Through the cooperation between the clamping groove and the limiting edge, the piston can be prevented from rotating in the piston hole, and the service life of the piston and the piston hole can be improved.

[0039] Further, limiting rings 16 are provided at both ends of the circumferential surface of the connecting column 18. The diameter of the limiting ring 16 is larger than the diameter of the through hole 26. The limiting rings are provided to play a limiting role on the connecting column.

[0040] Further, the rotating rod includes a threaded rod 4 and a connecting rod 23. An axial clamping hole 24 is provided on the threaded rod 4, and a clamping plate 25 matching and clamping with the clamping hole 24 is provided at one end of the threaded rod 4. When the rotating rod rotates, the clamping plate rotates in the clamping hole, so that the connecting rod does not need to rotate with the threaded rod.

[0041] As a further improvement of this embodiment, a fixing plate 28 is further provided on the base 1, and a soft pad 29 is provided on the end surface of the fixing plate 28 in contact with the mobile phone screen 9.

[0042] Further, two guiding and positioning blocks 30 are provided on the end surface of the fixing plate 28 in contact with the mobile phone screen 9. The distance between the two guiding and positioning blocks 30 is adapted to the width of the mobile phone screen 9.

[0043] Among them, when the mobile phone screen is fixed, first make one side of the mobile phone contact with the fixing plate. The guiding and positioning blocks on the fixing plate play a preliminary limiting role on the mobile phone, so that the subsequent clamping device can better fix the mobile phone screen.

[0044] As a further improvement of this embodiment, flanges 15 for limiting and supporting the mobile phone screen 9 are provided on both sides of the end surface of the airbag plate 12 in contact with the mobile phone screen 9. The edge positions on the sides of the mobile phone screen are relatively vulnerable positions. By providing flanges on the sides of the airbag plate, on the one hand, the mobile phone screen can be better limited and clamped, and on the other hand, the edge positions on the sides of the mobile phone screen can be well protected to prevent the mobile phone screen from being damaged.

[0045] As a further improvement of this embodiment, an installation disc 2 is provided at one end of the rotating rod away from the rotating positioning plate 8, and a plurality of force-applying rods 3 are evenly distributed on the circumferential surface of the installation disc 2.

[0046] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to vary. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
