[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] First, as Figure 1 As shown, the present application provides a guide rail profile accuracy adjustment device, which is installed at the bottom of the display equipment production line guide rail 10, and is used to adjust the profile accuracy of the display equipment production line guide rail 10, including: Mounting frame 1; A horizontal push-pull assembly 2 is mounted on the mounting frame 1; The first wedge 3 is connected to the horizontal push-pull assembly 2, and the horizontal push-pull assembly 2 is used to drive the first wedge 3 to slide horizontally on the mounting frame 1, and the top surface of the first wedge 3 is inclined downward along one of the sliding directions of the first wedge 3; The second wedge 4 has its top installed at the bottom of the display equipment production line guide rail 10 and is connected to the mounting frame 1 for lifting and sliding, and its bottom surface is in contact with the top surface of the first wedge 3 .

[0032] Specifically, when the first wedge 3 slides horizontally on the mounting frame 1, relative sliding occurs between the first wedge 3 and the second wedge 4. When the top surface of the first wedge 3 is inclined and the bottom surface of the second wedge 4 remains in contact with the top surface of the first wedge 3, the average thickness of the portion of the first wedge 3 directly below the second wedge 4 changes, causing the height of the second wedge 4 to change, and the second wedge 4 to move up and down. Therefore, it is only necessary to install the guide rail profile accuracy adjustment device 20 at the bottom of the display equipment production line guide rail 10, and drive the first wedge 3 to slide horizontally on the mounting frame 1 based on the horizontal push-pull component 2, so that the local guide rail on the top of the second wedge 4 can be lifted and lowered based on the lifting and lowering of the second wedge 4, thereby achieving the adjustment of the profile accuracy of the display equipment production line guide rail 10.

[0033] The guide rail profile accuracy adjustment device of the present application can drive the first wedge 3 to slide horizontally based on the horizontal push-pull component 2 to make the second wedge 4 move up and down, thereby being able to adjust the profile accuracy of the display equipment production line guide rail 10 based on a simple structure, and the guide rail profile accuracy adjustment device of the present application can generate a larger lifting force, thereby being able to adjust the profile accuracy of the display equipment production line guide rail 10 more labor-saving.

[0034] Preferably, the slope of the top surface of the first wedge 3 is in the interval [0.5, 0.6].

[0035] More preferably, the slope of the top surface of the first wedge 3 is 0.57.

[0036] In some preferred embodiments, the horizontal push-pull assembly 2 includes: The motion conversion assembly 21 is mounted on the mounting frame 1, and its output end is connected to the first wedge 3; The deceleration component 22 has an input end as an adjustment end and an output end connected to the input end of the motion conversion component 21. The deceleration component 22 is used to reduce the speed of the adjustment action on its input end and convert it into a rotational action at its output end to drive the input end of the motion conversion component 21 to rotate. The motion conversion component 21 is used to convert the rotational action at its input end into a horizontal sliding action at its output end on the mounting frame 1 to drive the first wedge 3 to slide horizontally on the mounting frame 1.

[0037] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a deceleration component 22 and a motion conversion component 21, and the input end of the deceleration component 22 can be adjusted to allow the output end of the motion conversion component 21 to slide horizontally, thereby enabling the horizontal push-pull component 2 to drive the first wedge 3 to slide horizontally.

[0038] In some preferred embodiments, the deceleration assembly 22 includes: The worm 221 is horizontally mounted on the mounting frame 1 and is rotationally connected to the mounting frame 1, and one end of the worm 221 is the input end of the speed reduction assembly 22; The worm wheel 222 is rotatably mounted on the mounting frame 1 , meshes with the other end of the worm 221 , and is connected to the input end of the motion conversion assembly 21 .

[0039] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a worm wheel 222 and a worm 221, and the worm 221 can be rotated during the profile accuracy adjustment process to rotate the worm wheel 222, thereby realizing the rotation of the reduction assembly 22, and the present application only needs to reasonably design the size and number of teeth of the worm wheel 222 and the worm 221, so as to adjust the lifting force of the guide rail profile accuracy adjustment device 20 to more effortlessly adjust the profile accuracy of the display equipment production line guide rail 10, and can adjust the horizontal sliding amplitude of the motion conversion assembly 21 and the first wedge 3 without changing the rotation angle of the worm wheel 222, so as to adjust the lifting amplitude of the second wedge 4, and can prevent the adjustment amplitude from being too large, so as to more accurately adjust the profile accuracy of the display equipment production line guide rail 10.

[0040] Preferably, the guide rail profile accuracy adjustment device further comprises: The driving mechanism 5 is connected to the worm 221 and is used for driving the worm 221 to rotate.

[0041] Specifically, in Figure 6 In other embodiments shown, the worm 221 can be rotated manually, or based on other adjustment parts other than the components included in the guide rail profile accuracy adjustment device. In this embodiment, the worm 221 is rotated based on the driving mechanism 5, and the driving mechanism 5 can be a mechanism such as a motor that can drive the worm 221 to rotate.

[0042] like Figure 7 As shown, in some preferred embodiments, the motion conversion component 21 includes: The gear 211 is horizontally mounted on the mounting frame 1 and is coaxially connected to the worm gear 222; The rack 212 is horizontally arranged and meshes with the gear 211 , and one end of the rack 212 is fixedly connected to the first wedge 3 .

[0043] Specifically, when the worm wheel 222 rotates, the gear 211 coaxially connected thereto rotates accordingly, and can drive the rack 212 meshing therewith to produce a horizontal displacement, thereby driving the first wedge 3 to slide horizontally on the mounting frame 1 .

[0044] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a gear 211 and a rack 212, which can horizontally displace the rack 212 based on the rotation of the gear 211, thereby enabling the motion conversion component 21 to drive the first wedge 3 to slide horizontally on the mounting frame 1.

[0045] Preferably, the gear 211 is a half gear. In some preferred embodiments, the mounting frame 1 has a first limiting portion 11 disposed on one side of the first wedge 3 , and the horizontal push-pull assembly 2 is used to drive the first wedge 3 to slide horizontally toward or away from the first limiting portion 11 .

[0046] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a first limit portion 11, which can limit the sliding range of the first wedge 3 on the mounting frame 1 to prevent the first wedge 3 from sliding excessively and causing the second wedge 4 to slide off the first wedge 3.

[0047] like Figure 2 As shown, in some preferred embodiments, the second wedge 4 has a sliding portion 41 on one side close to the first limiting portion 11; The first limiting portion 11 has a vertically arranged sliding groove 111; The second wedge 4 is connected to the mounting frame 1 in a lifting and sliding manner based on the sliding of the sliding portion 41 in the sliding groove 111 .

[0048] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a sliding groove 111, which can realize the lifting and sliding connection between the second wedge 4 and the mounting frame 1, and can prevent the second wedge 4 from sliding in a direction other than the sliding direction of the first wedge 3 when the first wedge 3 slides horizontally, causing deviations in the profile accuracy adjustment process.

[0049] In some preferred embodiments, the sliding groove 111 is a dovetail groove.

[0050] Specifically, since the width of the dovetail groove is smaller than the width of the groove bottom, the second wedge 4 can only be raised and lowered and slid on the mounting frame 1, and cannot slide in the horizontal direction. Therefore, in this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a dovetail groove, which can lock the sliding direction of the second wedge 4, thereby better preventing deviations in the profile accuracy adjustment process.

[0051] In some preferred embodiments, the mounting frame 1 has a second limiting portion 12 disposed on one side of the first wedge 3 and opposite to the first limiting portion 11 .

[0052] In this embodiment, the guide rail profile precision adjustment device of the present application can limit the sliding range of the first wedge 3 on the mounting frame 1 from the two sliding directions of the first wedge 3, thereby ensuring that the second wedge 4 will not slide off the first wedge 3 due to excessive sliding of the first wedge 3.

[0053] like Figure 3 As shown, in some preferred embodiments, the first wedge 3 has a vertically arranged mounting groove 31; The second wedge 4 and the mounting frame 1 respectively have a first mounting hole 42 and a second mounting hole 13 which are vertically arranged. The first mounting hole 42 , the second mounting hole 13 and the mounting groove 31 are arranged opposite to each other.

[0054] In this embodiment, the guide rail profile accuracy adjustment device of the present application is provided with a first mounting hole 42, a second mounting hole 13 and a mounting groove 31. The mounting frame 1 can be fixedly mounted on the bottom of the display equipment production line guide rail 10 based on the second mounting hole 13 only by using a screw or other connecting parts, and the first wedge 3 and the second wedge 4 are installed between the mounting frame 1 and the display equipment production line guide rail 10. In addition, the first wedge 3 of the present application has a mounting groove 31, which facilitates the horizontal sliding of the first wedge 3 on the mounting frame 1. Therefore, the present application can install the guide rail profile accuracy adjustment device 20 on the bottom of the display equipment production line guide rail 10 to adjust the profile accuracy of the guide rail.

[0055] Second, as Figure 4 and Figure 5 As shown, the present application provides a display equipment production line guide rail, and a plurality of guide rail profile precision adjustment devices 20 as described above are arranged at the bottom of both sides.

[0056] Specifically, the guide rail profile accuracy adjustment device 20 can adjust the profile accuracy of the local area of ​​the display equipment production line guide rail 10 where it is located. Therefore, the multiple guide rail profile accuracy adjustment devices 20 arranged at the bottom of both sides of the display equipment production line guide rail 10 can cooperate to adjust the overall profile accuracy of the guide rail.

[0057] The display equipment production line guide rail provided in the present application can adjust the surface accuracy of the display equipment production line guide rail 10 through a simple structure based on multiple guide rail profile accuracy adjustment devices 20 installed at the bottom of both sides thereof, and can make the guide rail profile accuracy adjustment process more labor-saving based on the larger lifting force generated by the guide rail profile accuracy adjustment device 20.

[0058] As can be seen from the above, the present application provides a guide rail profile accuracy adjustment device and a display equipment production line guide rail, wherein the guide rail profile accuracy adjustment device provided by the present application can drive the first wedge 3 to slide horizontally based on the horizontal push-pull component 2 to make the second wedge 4 move up and down, thereby being able to adjust the profile accuracy of the display equipment production line guide rail 10 based on a simple structure, and the guide rail profile accuracy adjustment device of the present application can generate a larger lifting force, thereby being able to adjust the profile accuracy of the display equipment production line guide rail 10 more effortlessly.
