Technical Field

[0001] This utility model relates to the field of production and testing tooling technology for ultra-large screens, specifically to a testing device for the production of ultra-large screens that can perform multi-point testing. Background Technology

[0002] One type of ultra-large screen uses a single-substrate structure to integrate display units and control them via a controller. After production, this type of display requires testing of various parts, one of which is defect detection. Screen display data is collected by a corresponding detection unit to analyze the screen's condition. However, most existing equipment operates on a single-point detection mode. When it is necessary to improve the efficiency of the detection work, multiple sets of equipment are connected in parallel. This can only serve as a temporary detection method, making the detection of ultra-large screens unsatisfactory. Therefore, it is necessary to design a fixture with multi-point detection capabilities. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a multi-point detection device for the production of ultra-large screens. This device is achieved by setting up multiple sets of position-adjustable detection installation units, along with corresponding guide structures and drive adjustment structures. This allows for the selection and assembly of multi-point detection fixtures at corresponding positions according to design requirements, thereby enabling multi-point detection of the screen.

[0031] The mounting bracket 2 has a threaded hole 6, and the mounting bracket 2 is configured to cooperate with the threaded rod 5 through the threaded hole 6.

[0032] The drive motor 7 is fixedly mounted on the frame 1, and the output shaft of the drive motor 7 is connected to the front end shaft of the threaded rod 5 for transmission.

[0033] The support rod 8 is fixedly installed on the rear inner wall of the storage compartment 4, and the support rod 8 is movably inserted into the threaded hole 6 on the mounting bracket 2.

[0034] The support spring 9 is sleeved on the support rod 8, and the rear end of the support spring 9 is fixedly set on the inner wall of the storage compartment 4, while the front end of the support spring 9 abuts against the mounting bracket 2 located on the left rear side.

[0035] The guide rod 10 is fixedly installed at the rear end of the threaded rod 5, and the cross-sectional radius of the guide rod 10 is smaller than the cross-sectional radius of the threaded rod 5. The guide rod 10 is inserted into the threaded hole 6 of the mounting bracket 2 located at the frontmost side inside the storage compartment 4.

[0036] Support arms 11, there are two support arms 11 which are symmetrically arranged on the left and right and are rotated on the frame 1 by a pivot, and the support arms 11 are positioned above the storage compartment 4.

[0037] The limiting arm 12 is spun onto the front end of the support arm 11 via a rotating shaft;

[0038] Limiting pin 13, the limiting pin 13 is fixedly disposed at the front end of the limiting arm 12;

[0039] The limiting seat 20 is fixedly installed on the upper side wall of the mounting frame 2, and the limiting pin 13 is configured to cooperate with the limiting seat 20.

[0040] Guide sleeve 14, the guide sleeve 14 is fixedly mounted on the support arm 11, and the guide sleeve 14 is arranged in an arc shape with the rotation axis of the support arm 11 and the limiting arm 12 as the center;

[0041] The guide frame 15 is fixedly mounted on the limiting arm 12 and is movably inserted into the guide sleeve 14.

[0042] The limiting spring 16 is sleeved on the guide frame 15, and one end of the limiting spring 16 is fixedly mounted on the guide sleeve 14, and the other end of the limiting spring 16 is fixedly mounted on the limiting arm 12.

[0043] Hydraulic rod 17, which is fixedly mounted on frame 1;

[0044] Connecting seat 18, which is fixedly mounted on the output shaft of hydraulic rod 17;

[0045] The connecting arm 19 is screwed onto the connecting seat 18 via a rotating shaft, and the front end of the connecting arm 19 is screwed onto the rear end of the support arm 11 via a rotating shaft.

[0046] When using this device, a detection unit for the screen is installed on the mounting frame 2. The frame 1 is movably mounted above the screen to be tested. The frame 1 moves, thereby moving the mounting frame 2 and the detection unit on it. The detection unit detects the screen. By setting different numbers of mounting frames 2 and detection units, multi-point detection of the screen can be achieved. When setting up multi-point mounting frames 2 and detection units, the drive motor 7 drives the threaded rod 5 to rotate forward. Then, the hydraulic rod 17 pulls the connecting seat 18 backward. The connecting seat 18 pulls the support arm 11 to rotate through the connecting arm 19, causing the front end of the support arm 11 to open the limiting arm 12. The limiting arm 12 then drives the limiting pin 13 to open and disengage from the limiting seat 20 on the mounting frame 2. The support spring 9 pushes the mounting frame 2 forward, causing the mounting frame 2 to move back and forth in the storage compartment 4. The mounting frame 2 at the front is fitted onto the threaded rod 5 through its threaded hole 6. As the threaded rod 5 rotates... The mounting bracket 2, located at the front of the storage compartment 4, is fitted onto the threaded rod 5 and slid into the guide compartment 3 via the threaded rod 5. The hydraulic rod 17 pushes the connecting seat 18 forward, causing the front end of the support arm 11 to rotate and close. At this time, when there is a limit seat 20 between the two limit pins 13, the limit pin 13 abuts against the side wall of the limit seat 20, thus preventing the limit arm 12 from rotating and closing. At this time, the support arm 11 rotates, causing the guide bracket 15 to insert into the guide sleeve 14 and move, thereby pressing the limit spring 16. After the limit seat 20 between the limit pins 13 slides forward and moves away, the limit spring 16 pushes the limit arm 12 and the limit pin 13 to close, thus restricting the forward movement of the rear mounting bracket 2. When the mounting bracket 2 in the guide compartment 3 is moved into the storage compartment 4, the limit pin 13 is opened, and the threaded rod 5 is rotated in the opposite direction. The threaded rod 5 then pushes the mounting bracket 2 in the guide compartment 3 to move backward, causing the mounting bracket 2 to move backward into the storage compartment 4 and fit onto the support rod 8.

[0047] Compared with the prior art, the beneficial effects of this utility model are:

[0048] 1. This device sets up a guide chamber 3 and a storage chamber 4 with port docking, thereby setting a threaded rod 5 in the guide chamber 3 and a mounting bracket 2 with a threaded hole 6 in the storage chamber 4. The mounting bracket 2 is used to set up a detection unit. Then, the mounting bracket 2 is guided by a support rod 8 and a support spring 9 is set in the storage chamber 4. This allows the mounting bracket 2 in the storage chamber 4 to be moved into the guide chamber 3 or moved out of the guide chamber 3 into the storage chamber 4 in cooperation with the threaded rod 5.

[0049] 2. This device has a limiting arm 12 with a limiting pin 13 installed on the frame 1 via a support arm 11, and a limiting seat 20 that cooperates with the limiting arm 12 and the limiting pin 13 installed on the mounting frame 2. A guide sleeve 14 and a guide frame 15 are installed between the limiting arm 12 and the support arm 11, and a limiting spring 16 is installed. This allows the installation frame 2 in the storage compartment 4 to be restricted from entering the guide compartment 3 by opening and closing the limiting arm 12, thereby adjusting the spacing of the installation frame 2 located in the guide compartment 3.

[0050] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
