The test probe 3, mounted on the crossbeam assembly 2, can accurately contact the surface of the display screen 20 for testing and measurement. The test probe 3 can specifically be a probe for testing screen brightness and color, commonly used in the field of screen testing. By adjusting the position of the crossbeam assembly 2, testing of different areas of the display screen 20 can be achieved.

[0031] The test fixture proposed in this invention is highly adjustable and flexible, capable of accommodating displays and motherboards of different sizes, ensuring the accuracy and efficiency of testing. Simultaneously, the robust structure of the test fixture maintains the stability of the display and motherboard during testing, meeting diverse testing requirements.

[0032] The display screen 20 and the motherboard 10 are connected via an FPC cable 9. The motherboard 10 can be a general-purpose motherboard 10 or a motherboard 10 specific to the display screen 20. The base 1 also has a switch module electrically connected to the motherboard 10 for power-on / off operations, facilitating screen testing.

[0033] Specifically, the four side panels are clearly distinguished as a front side panel 12, a rear side panel 13, a left side panel 14, and a right side panel 15. The rear side panel 13 and the left side panel 14 have a first strip-shaped hole 71 along their length. The two main board limiting members 4 are two cubic limiting posts 41, each with a threaded hole at its end. A tightening head 42 with a threaded post passes through the first strip-shaped hole to the inside of the side panel and is threaded to the limiting post 41. By rotating and tightening the tightening head 42, the position of the limiting post 41 can be fixed, thus ensuring the stability of the main board 10 fixing area. This design makes the fixing of the main board 10 more reliable and adaptable to different main board 10 sizes and installation requirements.

[0034] In a specific embodiment, the rear side panel 13 integrates a blocking component (not shown in the figure), and the front side panel 12 is provided with a clamping component. The blocking component adopts an L-shaped folded edge structure, is vertically welded to the inner side of the side panel to form a rigid limiting edge, and is fitted with a rubber strip; the front side panel 12 is provided with a threaded hole, and the clamping component specifically includes a clamping bolt 8 installed at the threaded hole and a top plate (not shown in the figure) fixed to the end of the clamping bolt 8, the top plate being parallel to the rear side panel 13. When the display screen 20 is installed, the blocking component limits its lateral displacement, and the clamping component fixes the longitudinal position of the display screen 20 by pressing, the two working together to form a three-point positioning constraint.

[0035] The four side plates are a front side plate 12, a rear side plate 13, a left side plate 14, and a right side plate 15. Mounting grooves are formed along the length of the upper part of the left side plate 14 and the right side plate 15, providing a fixed position for the installation of the crossbar 6. The crossbar 6 is installed within the mounting grooves, extending along the length of the side plate to form a stable sliding track. The bottom ends of the crossbeam assembly 2 are fitted onto the crossbar 6, allowing the crossbeam assembly 2 to slide along the crossbar 6, thereby adjusting the position of the test probe 3. This design makes the movement of the crossbeam assembly 2 more flexible, easily adapting to different testing needs. Simultaneously, the presence of the crossbar 6 provides good support for the crossbeam assembly 2, ensuring its stability during sliding and preventing wobbling or displacement, thus improving the accuracy and reliability of the test.

[0036] The crossbeam assembly 2 includes: a crossbeam 21 parallel to the front side plate 12; support feet 22 vertically disposed at both ends of the crossbeam 21 and fitted onto the crossbar 6 at their bottom; an equipment beam 23 mounted on the crossbeam 21 and capable of sliding and adjusting its fixed position along the crossbeam 21; and a test probe 3 mounted on the equipment beam 23. The crossbeam 21, parallel to the front side plate 12, forms a support structure corresponding to the base 1. The support feet 22 are vertically disposed at both ends of the crossbeam 21, with round holes at their bottom to fit onto the crossbar 6. The design of the support feet 22 allows the crossbeam 21 to slide smoothly along the crossbar 6 while providing sufficient support to prevent the crossbeam 21 from wobbling or tilting during sliding. The equipment beam 23 is mounted on the crossbeam 21 and can slide and adjust its fixed position along the crossbeam 21. This design allows the equipment beam 23 to move flexibly according to actual needs, thereby achieving precise adjustment of the position of the test probe 3. The test probe 3 on the equipment beam 23 can accurately contact the surface of the display screen 20 for testing and measurement. By adjusting the position of the equipment beam 23, different areas of the display screen 20 can be tested and inspected, ensuring the comprehensiveness and accuracy of the test. This modular design makes the test rack more flexible and convenient, adaptable to different types and sizes of display screens 20, and meets various testing needs.

[0037] In a further embodiment, the crossbeam 21 has a second strip-shaped hole 72 along its length. The equipment beam 23 is fixedly connected to the crossbeam 21 by bolts passing through the second strip-shaped hole 72. Tightening the bolts can fix the position of the equipment beam 23, while loosening the bolts can adjust the position of the equipment beam 23 along the second strip-shaped hole 72, thereby achieving precise adjustment of the test probe 3. This design not only enhances the stability of the equipment beam 23, but also provides greater flexibility for adjusting the position of the test probe 3, ensuring that it can accurately correspond to different areas of the display screen 20 during the test.

[0038] In a further embodiment, the equipment beam 23 is vertically positioned to ensure the height adjustability of the test probe 3 in the vertical direction. A third strip-shaped hole 73 is provided vertically along the upper edge of the equipment beam 23. The test probe 3 is fixedly connected to the equipment beam 23 by bolts passing through the third strip-shaped hole 73. The bolt design allows for precise height and position adjustment of the test probe 3 on the equipment beam 23. This design enables the test probe 3 to accurately contact the surface of the display screen 20, ensuring the accuracy and reliability of the test. Simultaneously, the presence of the third strip-shaped hole 73 also facilitates fine-tuning of the test probe 3's position, meeting different testing requirements.

[0039] In a specific embodiment, an anti-slip pad (not shown in the figure) is also provided on the base plate corresponding to the area where the display screen is fixed. The anti-slip pad effectively increases the friction between the display screen and the base plate, preventing the display screen from sliding or shifting during testing. This design further enhances the stability of the test frame, ensuring that the display screen remains stable within the fixed area, thereby improving the accuracy and reliability of the test. The presence of the anti-slip pad makes the testing process safer and more reliable, especially in situations requiring precise testing, providing a stable testing platform for the display screen.
