Description

Technical Field

[0001] The invention relates to the technical field of display production, and in particular to a display rapid positioning jig. Background Art

[0002] When adjusting the brightness uniformity and color uniformity of the display, the display and the instrument need to be positioned. Using simple jigs to position the display and the instrument cannot quickly and accurately position them within the specifications. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a display rapid positioning fixture.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A quick positioning fixture for a display comprises a base plate, a turntable, a lifting frame and a support frame. A slewing bearing is provided in the middle of the base plate, the turntable is rotatably connected to the slewing bearing, the support frame and the lifting frame are respectively fixed to the upper end surface of the turntable, a loading platform for carrying the display is fixed on the top of the lifting frame, and both sides of the support frame are rotatably connected to a back plate with an adjustable inclination angle through a support shaft, and the back plate is used to lean against the back of the display.

[0005] Furthermore, the turntable is provided with a first arc guide groove cocentric with the slewing bearing, the first arc guide groove is sleeved with a first locking bolt, the first locking screw passes through the first guide groove and is threadedly connected to the threaded hole on the base plate; the turntable is positioned by locking the first locking bolt.

[0006] Furthermore, the rear end of the support plate is provided with a second arc guide groove cocentric with the support shaft, the second arc guide groove is sleeved with a second locking bolt, the second locking screw passes through the second guide groove and is threadedly connected to the threaded hole on the support; the support plate is positioned by locking the second locking bolt.

[0007] Furthermore, the lifting frame is a manual lifting frame.

[0008] The present invention adopts the above technical solution and uses three-axis linkage to adjust the position of the display, so that the display can be quickly and accurately moved into the positioning frame designed by the software, thereby quickly and accurately locating the position of the instrument and the display. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0010] like Figure 1As shown, the display fast positioning fixture of the present invention includes a base plate 1, a turntable 2, a lifting frame 3 and a support frame 4. A slewing bearing 11 is provided in the middle of the base plate 1. The turntable 2 is rotatably connected to the slewing bearing 11. The support frame 4 and the lifting frame 3 are respectively fixed to the upper end surface of the turntable 2. A loading platform 5 for carrying the display is fixed on the top of the lifting frame 3. The loading platform 5 is a stepped structure. The lower end of the display abuts against the lower step to play a limiting role. The two sides of the support frame 4 are rotatably connected to a support plate 6 with an adjustable inclination angle through a support shaft. The support plate 6 is used to abut the back of the display.

[0011] Among them, the positioning structure of the turntable 2 after rotation is: a first arc-shaped guide groove 21 cocentric with the slewing bearing 11 is provided on the turntable 2, a first locking bolt 22 is sleeved on the first arc-shaped guide groove 21, and the first locking screw passes through the first guide groove and is threadedly connected with the threaded hole on the base plate 1; the turntable 2 is positioned by locking the first locking bolt 22.

[0012] The inclination positioning structure of the support plate 6 is the same as the positioning structure of the turntable, specifically as follows: a second arc-shaped guide groove 61 coaxial with the support shaft is provided at the rear end of the support plate 6, a second locking bolt 62 is sleeved on the second arc-shaped guide groove 61, and the second locking screw passes through the second guide groove and is threadedly connected to the threaded hole on the support; the support plate 6 is positioned by locking the second locking bolt 62.

[0013] The lifting frame 3 adopts the manual lifting frame 3 in the prior art. By manually rotating the handle, the loading platform 5 is driven to rise or fall.

[0014] The working principle of the present invention is as follows: the display is placed on the stage 5 and against the backrest 6, the probe of the instrument captures the image of the display and magnifies the position of the four corners of the display; the positions of the four corners of the display are captured into the same positioning frame, and then the height of the lifting frame 3, the inclination angle of the backrest 6 and the rotation angle of the turntable 2 are adjusted. When the positions of the four corners of the display present a rectangle or a square, it means that the positioning of the display and the display is accurate.

[0015] The above describes a specific embodiment of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
