[0043] like Figures 1-5As shown, in the initial state, the first permanent magnet 29 and the second permanent magnet 34 are magnetically connected. The first locking rod 32 is inserted between the two teeth of the first spur gear 30 to lock the first spur gear 30, preventing the first planar clamping member 7 and the first curved surface clamping member 8 from rotating during the clamping process. The fourth permanent magnet 43 and the third permanent magnet 40 are magnetically connected. The second locking rod 41 is inserted between the two teeth of the second spur gear 37 to lock the second planar clamping member 10 and the second curved surface clamping member 11 from rotating during the clamping process.

[0044] The working principle of clamping curved LCD screens:

[0045] On the two clamping boxes 6 above, the first planar clamping member 7 is located above the first curved clamping member 8, and the second planar clamping member 10 is located above the second curved clamping member 11. The second curved clamping member 11 is lower than the first curved clamping member 8, thereby adapting to the shape of the curved LCD screen.

[0046] On the two clamping boxes 6 below, the first planar clamping member 7 is located below the first curved clamping member 8, and the second planar clamping member 10 is located below the second curved clamping member 11. The second curved clamping member 11 is higher than the first curved clamping member 8, thereby adapting to the shape of the curved LCD screen.

[0047] The curved LCD screen is placed on the lower clamping assembly. Two first curved clamping members 8 and two second curved clamping members 11 support the curved LCD screen. The hydraulic piston rod 5 on the hydraulic cylinder 4 is extended, thereby causing the upper clamping assembly to move down. The two upper first curved clamping members 8 and the two upper second curved clamping members 11 abut against the curved LCD screen, and cooperate with the lower clamping assembly to clamp the curved LCD screen, so as to facilitate the inspection of the curved LCD screen.

[0048] The working principle of clamping a flat LCD screen:

[0049] like Figure 5 As shown, the device is adjusted in its initial state.

[0050] First, adjust the upper clamping assembly to shorten the cylinder piston rod 19 on the cylinder body 18. The connecting rod 15, linkage rod 14, and adjustable module 20 move upwards. The upper first permanent magnet 29 moves upwards and disengages from the magnetic connection with the second permanent magnet 34. The first slider 33 and the first locking rod 32 move in the opposite direction to the linkage rod 14 under the elastic force of the first spring 35, thereby releasing the first locking rod 32 from locking the first spur gear 30, allowing the first spur gear 30 to rotate smoothly. The fourth permanent magnet 43 moves upwards and disengages from the magnetic connection with the lower third permanent magnet 40. The second locking rod 41 and the second slider 42... Under the elastic force of the second spring 44, the gear moves in the opposite direction to the rack 39, thereby releasing the second locking lever 41 from the second spur gear 37, allowing the second spur gear 37 to rotate smoothly. Then, the transmission teeth 28 on the linkage rod 14 mesh with the first spur gear 30, thereby driving the first spur gear 30, the fourth rotating wheel 31, the first transmission chain 25, the first rotating wheel 24, the first planar clamping member 7, and the first curved surface clamping member 8 to rotate. The second spur gear 37 meshes with the rack 39, thereby driving the second spur gear 37, the third rotating wheel 38, the first permanent magnet 29, the second rotating wheel 26, the second planar clamping member 10, and the rack 39 to rotate. The second curved surface clamping member 11 rotates, the transmission gear 28 disengages from the first spur gear 30, and the second spur gear 37 and rack 39 disengage. Then, the positions of the first flat clamping member 7 and the first curved surface clamping member 8 are interchanged, and the positions of the second flat clamping member 10 and the second curved surface clamping member 11 are interchanged. The adjustable module 20 moves upward so that the bottom wall of the rotated second flat clamping member 10 is flush with the bottom wall of the first flat clamping member 7, adapting to the shape of the flat LCD screen. The lower first permanent magnet 29 moves upward to the same horizontal plane as the second permanent magnet 34, and the lower first permanent magnet 29 magnetically connects to the second permanent magnet 34, thereby enabling the first slider 33... The first locking lever 32 moves towards the linkage lever 14, and the first locking lever 32 re-inserts between the two teeth of the first spur gear 30 to lock, preventing the first planar clamping member 7 and the first curved clamping member 8 from rotating during the clamping process. The fourth permanent magnet 43 moves up to the same horizontal plane as the upper third permanent magnet 40, and the upper third permanent magnet 40 magnetically attracts the fourth permanent magnet 43, thereby causing the second slider 42 and the second locking lever 41 to move towards the rack 39, thereby causing the second locking lever 41 to lock the second spur gear 37 again, preventing the second planar clamping member 10 and the second curved clamping member 11 from rotating during the clamping process.

[0051] Then, the lower clamping assembly is adjusted to shorten the cylinder piston rod 19 on the cylinder body 18. Referring to the above principle, the first planar clamping member 7 and the first curved clamping member 8 are swapped, and the second planar clamping member 10 and the second curved clamping member 11 are swapped. The first planar clamping member 7 is located above the first curved clamping member 8, and the second planar clamping member 10 is located above the second curved clamping member 11, so as to adapt to the shape of the flat LCD screen.

[0052] The flat LCD screen is placed on the lower clamping assembly. The two first-plane clamping members 7 and the two second-plane clamping members 10 support the flat LCD screen. The hydraulic piston rod 5 on the hydraulic cylinder 4 is extended, thereby causing the upper clamping assembly to move down. The two upper first-plane clamping members 7 and the two upper second-plane clamping members 10 abut against the flat LCD screen, and cooperate with the lower clamping assembly to clamp the flat LCD screen, so as to facilitate the testing of the flat LCD screen.

[0053] This invention enables convenient clamping of LCD screens through the control of hydraulic cylinder 4, eliminating the need for manual rotation of components. This meets the high-efficiency requirements of current assembly line production and testing, saving manpower. The clamping assembly mode can be adjusted and switched by the drive of cylinder 18 to adapt to curved and flat LCD screens, clamping LCD screens of different shapes without the need for multiple devices to clamp curved and flat LCD screens, thus improving the adaptability of the device.

[0054] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
