Description

Technical Field

[0001] This utility model relates to the field of tooling technology for display screen production, specifically to a strength testing machine for panoramic display screen production. Background Technology

[0002] With the advancement and improvement of ultra-large area display screen manufacturing technology, integrated displays are gradually replacing traditional spliced ​​displays, which are now commonly used in exhibition halls and squares. During the production process of ultra-large area single displays, pressure testing is required to determine the strength of the screen panel according to production needs. However, the production cost of ultra-large area displays is high, making it impossible to conduct tests that pose a risk of damage using finished product sampling. Therefore, sample testing is conventionally used. However, when using samples for testing, there are certain errors due to the shape difference between samples and finished products. Relying solely on the measured data for mathematical conversion introduces certain errors. Moreover, when testing screen products of different sizes, it is necessary to use corresponding conversion formulas for each one. The measured values ​​are not intuitive during operation. Therefore, the development of new strength testing equipment is needed. Utility Model Content

This machine uses a tray to hold the sample to be tested, and supports are installed on all four sides of the tray. An adjustable support clamping structure is also included. During pressure testing, the tray and supports provide support and simulate the bending of the substrate of the finished product, thus creating an equivalent area of ​​support for the sample. By adjusting the support points of the supports, different product areas can be simulated for pressure testing.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-4 As shown, the specific implementation adopts the following technical solution:

[0026] It includes a frame 1 and a tray 2, wherein the tray 2 is disposed inside the frame 1, and it also includes:

[0027] Support plate 3, there are four support plates 3 and they are respectively fixedly installed on the four sides of the support plate 2;

[0028] Threaded rod 11, which is screwed onto frame 1 via bearings;

[0029] The lifting seat 4 is threadedly sleeved on the threaded rod 11 and is located below the support plate 2.

[0030] The drive motor 12 is fixedly mounted on the frame 1, and the output shaft of the drive motor 12 is connected to the lower end shaft of the threaded rod 11 via a spline transmission.

[0031] Guide rod 9, which is fixedly mounted on frame 1;

[0032] Support 6, which is movably sleeved on guide rod 9, and is located below support plate 3;

[0033] Support rod 5, the support rod 5 is spun on the side wall of the lifting seat 4 via a rotating shaft, and the end of the support rod 5 away from the lifting seat 4 is spun on the support seat 6 via a rotating shaft;

[0034] The clamping claw 7 is fixedly mounted on the support base 6 and is movably locked on the support plate 3. The support plate 3 is integrally formed with an anti-slip groove 8, and the inner wall of the teeth of the clamping claw 7 abuts against the anti-slip groove 8.

[0035] Hydraulic jack 17, wherein the hydraulic jack 17 is fixedly mounted on the frame 1;

[0036] The load-bearing seat 18 is fixedly mounted on the output shaft of the hydraulic jack 17 and is located below the support plate 2.

[0037] The lifting platform 13 is positioned above the support plate 2;

[0038] Guide ring 15, the guide ring 15 is fixedly installed on the lifting platform 13, and the guide ring 15 is movably sleeved on the vertical rod of the frame 1;

[0039] The limiting ring 16 is fixedly installed at the upper end of the frame 1 and is located above the lifting platform 13.

[0041] Side ring frame 10, the side ring frame 10 is disposed outside the frame 1, and the end of the guide rod 9 away from the frame 1 is fixedly disposed on the side ring frame 10.

[0042] When using this device, a sample of the screen workpiece is placed on the tray 2. After adding a counterweight to the lifting platform 13, the pressure head 14 is pressed down by the lifting platform 13. The pressure head 14 presses the sample to perform pressure testing. When pressing the sample, the tray 2 and support plate 3 are simultaneously pushed downward to bend, thereby forming support for the sample. The bent tray 2 and support plate 3 form an equivalent area support for the sample, which is the area of ​​the full-size finished screen corresponding to the sample. When adjusting the equivalent area for different screen sizes, the drive motor 12 drives the threaded rod 11 to rotate, and the threaded rod 11 pushes the lifting seat 4 to move up and down. The guide rod 9 supports and linearly guides the support seat 6.

Rotation: The lifting seat 4 moves vertically and pushes the support seat 6 horizontally via the support rod 5. When the support seat 6 moves horizontally, the clamping claw 7 is released, allowing the clamping claw 7 to move and adjust its position on the support plate 3. This allows for adjustment of the equivalent area value by adjusting the distance between the clamping claw 7 and the pallet 2. After adjustment, the clamping claw 7 is locked to clamp the support plate 3. The pressure head 14 presses down, causing the pallet 2 to bend and descend. When limiting the maximum downward movement height of the pallet 2, the height of the load-bearing seat 18 is adjusted by the hydraulic jack 17, so that the pallet 2 descends and abuts against the load-bearing seat 18 to achieve the limit. When a counterweight is installed on the relevant lifting platform 13, the counterweight is placed on the lifting platform 13 after passing through the fiber ring, and the counterweight is simultaneously limited and guided by the limit ring 16.
