[0001] This application relates to the technical field of jigs, and more particularly, to a test fixture tooling. Background Art

[0002] A liquid crystal panel such as an LCD is composed of an upper substrate assembly, a lower substrate assembly, liquid crystal, a driving circuit unit, a backlight module, and other accessories. The LCD backlight module is composed of components such as an upper diffusion sheet, a lower diffusion sheet, a brightness enhancement film, a light guide plate, an aluminum backplane, a rubber frame, and a light source. Each component of the LCD is interconnected and interferes with each other. There are environments of LCD handling and vibration in all links of LCD production and assembly, packaging and transportation, and customer use. The long-term cumulative effect or intense vibration environment may affect the picture quality of the LCD. When manufacturers produce LCDs, they often see phenomena such as Cell foreign objects, polarizer foreign objects, and BLU foreign objects in the LCD. When customers use the display screen, they may sometimes find that there is dirt on the liquid crystal screen. In fact, it is caused by foreign objects entering the visible area of the LCD display screen during the vibration environment or handling process.

[0003] In the related technology, in the tooling for liquid crystal panel vibration testing, the opening size is fixed and cannot be changed, and it can only correspond to one or two products. Summary of the Utility Model

[0039] Embodiment

[0040] Industrial configuration serial port screens come in different sizes. The smallest is only 1.5 inches (with an external dimension of approximately 44*32MM), and the largest is up to 12.1 inches (with an external dimension of approximately 290*230MM) or more, and they have different forms (either with a housing or with an adhesive backing). Therefore, the compatibility requirements for the fixture tooling of the vibration test bench are extremely demanding, which is also the difficulty in design. The current clamping solutions have at least the following disadvantages: Lack of materials: It is difficult to find suitable acrylic or bakelite materials for the screen sizes to be tested; Waste of materials: When milling the plate for the screen size, the slot size cannot be changed, and it cannot be compatible with other screen sizes, and it can only be left idle after testing; Poor compatibility: The hole size is fixed and cannot be changed, and it can only correspond to one or two products.

[0041] In view of this, as Figures 1-4 shown, in a first aspect, an embodiment of the present application provides a test fixture tooling, including: a fixture box body, which is configured with a first panel 100, a second panel 200, a third panel 300, and a fourth panel 400 connected in sequence. The first panel 100 is configured with a first test area 101, the second panel 200 is configured with a second test area 201, the third panel 300 is configured with a third test area 301, and the fourth panel 400 is configured with a fourth test area 401. The first test area 101, the second test area 201, the third test area 301, and the fourth test area 401 are all configured with fixing parts, and the first test area 101, the second test area 201, the third test area 301, and the fourth test area 401 are configured to be used for setting a test piece 800; a limiting component, which is connected to the fixing parts of the first test area 101, the second test area 201, the third test area 301, and / or the fourth test area 401, and the position where the limiting component is connected to the fixture box body is adjustable for limiting the test piece 800.

[0042] Exemplarily, the test fixture tooling provided by the present application is used to fix the test piece 800 to be tested, where the test piece 800 to be tested includes but is not limited to an industrial configuration serial screen. The industrial configuration serial screen is a display device specifically used in the industrial field. It combines the characteristics of serial communication technology and configuration software. The industrial configuration serial screen is a liquid crystal screen with serial control. Its main feature is data transmission through the serial port, and it can display Chinese and Western characters and picture files of various fonts and colors on the display at the same time. Users can call up fixed pictures in the SD card in the form of instructions and realize combined, cyclic, alternating, and overlapping displays with on-site real-time data.

[0043] It can be understood that the first panel 100, the second panel 200, the third panel 300, and the fourth panel 400 are sequentially connected to enclose a cavity. Among them, several screws can be used to fix the first panel 100 to the second panel 200 and the fourth panel 400 to each other, and several screws can be used to fix the third panel 300 to the second panel 200 and the fourth panel 400 to each other, so as to realize the mutual engagement between the panels.

[0044] In the above implementation process, the first panel 100, the second panel 200, the third panel 300, and the fourth panel 400 are all provided with test areas. The test areas of each panel can be connected to the limit components through the fixing parts, and the position of the limit components relative to the test area of the fixture box body is adjustable and the limit components are connected to different test areas, which can be used to adapt to test pieces 800 of multiple sizes and realize the vibration test requirements for test pieces 800 of different sizes.

[0045] As Figures 1-2 shown, the first panel 100 and the third panel 300 are distributed relatively, the second panel 200 and the fourth panel 400 are distributed relatively, and the first panel 100 is adjacent to the second panel 200 and the fourth panel 400 respectively; among them

[0046] A part of the structure of the first panel 100 is recessed in the direction close to the third panel 300 to form at least one first test area 101, a part of the structure of the second panel 200 is recessed in the direction close to the fourth panel 400 to form at least one second test area 201, a part of the structure of the third panel 300 is recessed in the direction close to the first panel 100 to form at least one third test area 301, and a part of the structure of the fourth panel 400 is recessed in the direction close to the second panel 200 to form at least one fourth test area 401.

[0047] Exemplarily, one is configured in the first test area 101, and two are configured in each of the second test area 201, the third test area 301, and the fourth test area 401. For example, the second panel 200, the third panel 300, and the fourth panel 400 are all configured with reinforcing ribs 900 (which can be used to enhance the structural strength of the fixture box body) to form two of the second test areas 201, two of the third test areas 301, and two of the fourth test areas 401. It can be understood that the reinforcing rib 900 can also be formed by a partial structure of the second panel 200 (the third panel 300 or the fourth panel 400) being recessed to form a structure on the second panel 200.

[0048] It can be understood that the second test area 201, the third test area 301, and the fourth test area 401 can be used to adapt the test piece 800 with a size from 1.5 inches to 10.1 inches, while the first test area 101 can be used to adapt the test piece 800 with a size of more than 12 inches.

[0049] In the above implementation process, the first panel 100, the second panel 200, the third panel 300, and the fourth panel 400 are all recessed to form the test area. This can not only fix the limiting component, but also ensure the stability of the test piece 800 during the vibration test when the test piece 800 is placed in the test area and limited by the limiting component, which is beneficial to meeting the vibration test requirements for test pieces 800 of different sizes.

[0050] In some embodiments, the first test area 101 is configured with a plurality of first fixing holes 102. The plurality of first fixing holes 102 are spaced apart along a first direction and a second direction. The first fixing holes 102 are used to connect with the limiting component, and the first direction is perpendicular to the second direction.

[0051] Exemplarily, the first direction includes but is not limited to the up-down direction, and the second direction includes but is not limited to the left-right direction. The plurality of first fixing holes 102 are arranged in two rows along both the first direction and the second direction, and the number of the first fixing holes 102 distributed along the first direction and the second direction is not specifically limited and can be set according to actual situations, which will not be elaborated here one by one.

[0052] In the above implementation process, the first test area 101 is configured with a plurality of first fixing holes 102. The position of the limiting component connected to the first test area 101 can be adjusted through the first fixing holes 102, so as to adapt to test pieces 800 of different sizes and meet their vibration test requirements.

[0053] In some embodiments, the second test area 201 is configured with a plurality of second fixing holes 202. The plurality of second fixing holes 202 are spaced apart along the first direction and the third direction. The second fixing holes 202 are used to connect with the limiting component, wherein the first direction is perpendicular to the third direction.

[0054] Exemplarily, the first direction includes but is not limited to the up-down direction, and the third direction includes but is not limited to the front-back direction. The plurality of second fixing holes 202 are arranged in two rows along both the first direction and the third direction, and the number of the first fixing holes 102 distributed along the first direction and the third direction is not specifically limited and can be set according to actual situations, which will not be elaborated one by one here.

[0055] In the above implementation process, the second test area 201 is configured with a plurality of second fixing holes 202. Through the second fixing holes 202, the position where the limiting component is connected to the second test area 201 can be adjusted, so as to adapt to test pieces 800 of different sizes and meet their vibration test requirements.

[0056] In some embodiments, the third test area is configured with a plurality of third fixing holes 302. The plurality of third fixing holes 302 are spaced apart along the first direction and the second direction. The third fixing holes 302 are used to connect with the limiting component.

[0057] Exemplarily, the first direction includes but is not limited to the up-down direction, and the second direction includes but is not limited to the left-right direction. The plurality of third fixing holes 302 are arranged in two rows along both the first direction and the second direction, and the number of the third fixing holes 302 distributed along the first direction and the second direction is not specifically limited and can be set according to actual situations, which will not be elaborated one by one here.

[0058] In the above implementation process, the third test area 301 is configured with a plurality of third fixing holes 302. Through the third fixing holes 302, the position where the limiting component is connected to the third test area 301 can be adjusted, so as to adapt to test pieces 800 of different sizes and meet their vibration test requirements.

[0059] In some embodiments, the fourth test area 401 is configured with a plurality of fourth fixing holes 402. The plurality of fourth fixing holes 402 are spaced apart along the first direction and the third direction. The fourth fixing holes 402 are used to connect with the limiting component, wherein the first direction is perpendicular to the third direction.

[0060] Exemplarily, the first direction includes but is not limited to the up-down direction, the third direction includes but is not limited to the front-back direction. There are two rows of a number of the fourth fixing holes 402 arranged along both the first direction and the third direction, and the number of the fourth fixing holes 402 distributed along the first direction and the third direction is not specifically limited and can be set according to the actual situation, which will not be elaborated one by one here.

[0061] In the above implementation process, a number of fourth fixing holes 402 are arranged in the fourth test area 401. The position where the limiting component is connected to the fourth test area 401 can be adjusted through the fourth fixing holes 402, so as to adapt to test pieces 800 of different sizes and meet their vibration test requirements.

[0062] In some embodiments, the limiting component includes a first limiting block 500 and a second limiting block 600. There are two first limiting blocks 500, and the two first limiting blocks 500 are spaced apart along the first direction. There are two second limiting blocks 600, and the two second limiting blocks 600 are spaced apart along the second direction. Among them, the two first limiting blocks 500 and the two second limiting blocks 600 are all located at the outer edge of the test piece 800.

[0063] Exemplarily, the lengths of the first limiting block 500 and the second limiting block 600 can be set to be inconsistent, which can ensure that during the adjustment process of the first limiting block 500 and the second limiting block 600 on the same panel, interference between the first limiting block 500 and the second limiting block 600 is avoided.

[0064] In the above implementation process, the first limiting block 500 is distributed along the first direction, and the second limiting block 600 is distributed along the second direction. When the first limiting block 500 and the second limiting block 600 are respectively connected to the fixture box body, they can form limits on different positions of the test piece 800, ensuring the stability of the test piece 800 during the vibration test process and improving the accuracy of the vibration test.

[0065] In some embodiments, the first limiting block 500 is provided with a first limiting groove 501 along the first direction. For example, the first limiting groove 501 is set to be strip-shaped, and the size of the first limiting groove 501 is larger than the size of the fixing part (i.e., the first fixing hole 102, the second fixing hole 202, the third fixing hole 302, and the fourth fixing hole 402).

[0066] In the above implementation process, by setting the size of the first limiting groove 501 to be larger than the size of the fixing part, it is beneficial to adjust the position where the first limiting block 500 is connected to the fixture box body, so as to adapt to test pieces 800 of different sizes.

[0067] In some embodiments, the second limiting block 600 is provided with a second limiting groove 601 along the second direction. For example, the second limiting groove 601 is arranged to be strip-shaped, and the size of the second limiting groove 601 is larger than that of the fixing portion.

[0068] In the above implementation process, by setting the size of the second limiting groove 601 to be larger than that of the fixing portion, it is beneficial to adjust the position where the second limiting block 600 is connected to the fixture box body, so as to adapt to test pieces 800 of different sizes.

[0069] As Figure 3 shown, the fixture box body further includes a bottom plate 700, and the bottom plate 700 is respectively connected to the first panel 100, the second panel 200, the third panel 300 and the fourth panel 400.

[0070] Exemplarily, the first panel 100, the second panel 200, the third panel 300 and the fourth panel 400 form a test area due to being recessed. Therefore, a stepped shape can be formed on one side of the first panel 100, the second panel 200, the third panel 300 and the fourth panel 400 close to the bottom plate 700, which can facilitate their connection to each other and is beneficial to the stability after connection.

[0071] It can be understood that a plurality of connection holes 701 are provided on the bottom plate 700, and the bottom plate 700 can be used to connect to the vibration test equipment through these connection holes 701 to ensure the stability after connection between the fixture tooling and the vibration test equipment.
