[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] Example 1

[0037] like Figure 1 and Figure 5As shown, a screen color detection mechanism comprises a machine platform 1, a bracket 2 is arranged on the machine platform 1, a rodless cylinder 3 is horizontally arranged on the bracket 2, a Z-direction motion mechanism is arranged on a slide 301 of the rodless cylinder 3, a screen detection instrument is installed at the motion end of the Z-direction motion mechanism, and the detection end of the screen detection instrument faces the machine platform 1;

[0038] Two limit rings are sleeved on the guide rod 302 of the rodless cylinder 3 , and the two limit rings are respectively located on both sides of the slide 301 for limiting the travel of the slide 301 .

[0039] The beneficial effects of this embodiment are: the rodless cylinder 3 and the Z-axis motion mechanism drive the screen detection instrument to move, which is suitable for the detection needs of screens of different sizes. The rodless cylinder 3 is compact in size, saves installation space, and has a fast response speed; and the travel of the slide 301 is limited by the limit ring according to the size of the screen to be detected, and the adjustment method is flexible.

[0040] Specifically, the machine table 1 is used to place the screen to be tested, the bottom of the bracket 2 is open, the rodless cylinder 3 drives the Z-direction motion mechanism to move horizontally, and the Z-direction motion mechanism drives the screen detection instrument to move vertically. The screen detection instrument detects the color of the screen and is suitable for screens of different sizes. The left and right double stations can also be set for detection as needed. The screen detection instrument moves left and right for cyclic detection to improve work efficiency;

[0041] The rodless cylinder 3 in this embodiment is a magnetic rodless cylinder. Figure 3 As shown, three rods are arranged in parallel on each rodless cylinder 3, with guide rods 302 on both sides and a piston rod in the middle. The slide 301 is slidably sleeved on the guide rods 302 and the piston rod. A movable piston is arranged inside the piston rod, a magnet is arranged inside the piston, and another set of magnets is arranged inside the slide 301. When the piston moves, the slide 301 is driven to move through magnetic coupling.

[0042] Compared with conventional electric telescopic rods and ordinary cylinders, the rodless cylinder 3 has a shorter total length, a more compact structure, occupies less space, and can save installation space when the same stroke is selected;

[0043] The cylinder usually has only two working positions, the starting position and the ending position, and it is difficult to stop at any position in the middle. If a special cylinder that can stop in the middle is used, the cost will be high. In this embodiment, during detection, the limit ring is installed at the corresponding position on the guide rod 302 according to the size of the screen to be tested. The limit ring is located on both sides of the slide 301 to limit the moving stroke of the slide 301, which can adapt to the detection requirements of different screen sizes. It is low-cost and easy to use.

[0044] On the basis of this embodiment, a buffer block is further installed on the side of the limit ring that contacts the slide 301 to mitigate impact and extend the service life.

[0049] As a parallel technical solution to the above-mentioned solution, the limiting ring can also be in a complete ring shape, which is sleeved on the guide rod 302. A plurality of screws are threadedly installed on the outer wall of the limiting ring. The axis of the screw is perpendicular to the axis of the limiting ring. One end of the screw passes through the outer wall of the limiting ring, extends into the inside and abuts against the outer wall of the guide rod 302, thereby achieving fixation.
