Description

Technical Field

[0001] This utility model relates to the field of LED bead testing technology, specifically to a bead testing device for LED displays. Background Technology

[0002] With the widespread application of large-scale LED electronic displays in advertising, stadiums, concerts, and many other fields, quality control of LED displays has become a crucial issue. In particular, the accuracy of quality testing for LED chips directly affects the stability and reliability of the display effect.

[0003] However, because LED chips themselves have a strong light source, especially in applications such as large electronic displays where the brightness of the chips is often high, traditional chip testing methods mostly rely on manual observation. This method has some significant drawbacks. First, visual inspection is easily affected by factors such as ambient light and the luminous intensity of the chip itself, leading to inaccurate results. Second, manually observing strong light sources can easily cause eye discomfort and even visual damage, especially when testing high-brightness chips, where the intense light source may have long-term effects on the eyes of workers. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an LED display screen bead detection device to solve the problem that manual observation of strong light sources can easily cause eye discomfort or even visual damage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A lamp bead detection device for LED displays, comprising:

[0006] Base;

[0007] The frame is set on top of the base;

[0008] A light shield, which is fitted over the outside of the frame;

[0009] The detection port is located on one side of the light shield;

[0010] A fixture containing LED chips, the fixture being located on a base, wherein the fixture is electrically connected to the LED chips;

[0011] A sliding assembly is disposed on a base, and the moving end of the sliding assembly is connected to a fixture, which is used to drive the fixture to move on the base to pass through the detection port and enter the light shield.

[0012] A light intensity detection component is mounted on the frame.

[0013] The beneficial effects of this utility model are:

[0014] By placing the LED bead to be tested in the fixture and making electrical connections, the fixture is moved on the base by the sliding component, passing through the detection port and entering the light shield. Inside the light shield, the luminous intensity of the LED bead can be accurately measured by the light intensity detection component, thereby judging the quality of the LED bead.

[0015] The light shield design effectively isolates the light from the LED beads, preventing workers from being directly exposed to strong light sources and thus protecting their eyesight. This is especially beneficial during the testing of high-brightness LED beads, avoiding the stimulation and potential harm of strong light to the eyes. Furthermore, the effective shielding of the light shield ensures that the light intensity detection component measures only the target light source in an environment free from external interference. This allows for accurate measurement of the luminous intensity of the LED beads, resulting in more precise test results. This helps identify quality defects in the LED beads and ensures the accuracy and reliability of the test results.

[0016] Based on the above technical solution, the present invention can be further improved as follows.

[0017] Furthermore, the sliding assembly includes a cylinder, a push plate, a slider, an opening, and two slide rails. One end of each slide rail passes through a detection port and is fixed to the top of the base. The slider slides outside the slide rails.

[0018] Furthermore, the opening is located between the slide rails and is formed on the base, the cylinder is fixed to the bottom of the base, one side of the push plate is fixed to the drive end of the cylinder, and the other side of the push plate is connected to the bottom of the fixture, and the fixture is fixed to the top of the slider.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the push plate is driven to move by the cylinder, and the push plate pushes the fixture to slide on the slide rail via the slider, thereby causing the fixture to move along the path of the slide rail.

[0020] Furthermore, a light-shielding curtain is fixedly connected to the top side wall of the detection port.

[0021] The beneficial effect of adopting the above-mentioned further solution is that using a light-shielding curtain not only does not interfere with the entry and exit of the fixture from the light-shielding cover, but also further prevents strong external light sources or unnecessary ambient light from entering the photosensitive area of ​​the light intensity detection component through the detection port, ensuring that the light intensity detection component only measures the light intensity of the target light source and is not affected by other surrounding light sources.

[0022] Furthermore, the light intensity detection component employs a light intensity sensor. Attached Figure Description

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] With the widespread application of large-scale LED electronic displays in advertising, stadiums, concerts, and many other fields, quality control of LED displays has become a crucial issue. In particular, the accuracy of quality testing for LED chips directly affects the stability and reliability of the display effect.

[0030] However, due to the strong light source of LED beads, especially in large electronic display applications where brightness is often high, traditional LED bead testing methods mostly rely on manual observation. This method has several significant drawbacks. First, visual inspection is easily affected by ambient light and the luminous intensity of the LED beads themselves, leading to inaccurate results. Second, manually observing strong light sources can easily cause eye discomfort and even visual damage, especially when testing high-brightness LED beads, where the intense light source may have long-term effects on the eyes of workers. To address these issues, the inventor has proposed an LED bead testing device for LED displays.

[0031] The present invention provides the following preferred embodiments.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an LED display screen LED bead detection device includes:

[0033] Base 10;

[0034] Frame 20, which is set on top of base 10;

[0035] A light shield 30 is fitted over the frame 20. The light shield 30 is made of an opaque material, such as aluminum or black plastic.

[0036] The detection port 40 is located on one side of the light shield 30;

[0037] A fixture 80 containing LED beads is located on a base 10, wherein the fixture 80 is electrically connected to the LED beads;

[0038] The sliding component 50 is disposed on the base 10, and the moving end of the sliding component 50 is connected to the fixture 80, which is used to drive the fixture 80 to move on the base 10 to pass through the detection port 40 and enter the light shield 30.

[0039] Light intensity detection component 60 is mounted on frame 20.

[0040] After the lamp bead to be tested is placed in the fixture 80 and electrically connected, the sliding component 50 drives the fixture 80 to move on the base 10, pass through the detection port 40 and enter the light shield 30. Inside the light shield 30, the luminous intensity of the lamp bead can be accurately measured by the light intensity detection component 60, thereby judging the quality of the lamp bead.

[0041] The light shield 30 effectively isolates the light from the LED beads, preventing workers from being directly exposed to strong light sources and thus protecting their eyesight. This is especially beneficial during the testing of high-brightness LED beads, avoiding the stimulation and potential harm of strong light to the eyes. Furthermore, the effective shielding provided by the light shield 30 ensures that the light intensity detection component 60 measures only the target light source in an environment free from external interference. This allows for accurate measurement of the luminous intensity of the LED beads, resulting in more precise test results. This helps identify quality defects in the LED beads and ensures the accuracy and reliability of the test results.

[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the sliding assembly 50 includes a cylinder 510, a push plate 520, a slider 530, an opening 540, and two slide rails 550. One end of each slide rail 550 passes through the detection port 40 and is fixed to the top of the base 10. The slider 530 slides outside the slide rails 550. The opening 540 is located between the slide rails 550 and is opened on the base 10. The cylinder 510 is fixed to the bottom of the base 10. One side of the push plate 520 is fixed to the drive end of the cylinder 510, and the other side of the push plate 520 is connected to the bottom of the fixture 80. The fixture 80 is fixed to the top of the slider 530.

[0043] The cylinder 510 drives the push plate 520 to move, and the push plate 520 pushes the fixture through the slider 530 to slide on the slide rail 550, thereby causing the fixture 80 to move along the path of the slide rail 550.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a light-shielding curtain 70 (made of light-shielding fabric) is fixedly connected to the top side wall of the detection port 40. Using the light-shielding curtain 70 will not only not interfere with the entry and exit of the fixture 80 from the light-shielding cover 30, but also further prevent strong external light sources or unnecessary ambient light from entering the photosensitive area of ​​the light intensity detection component 60 through the detection port 40. This ensures that the light intensity detection component 60 only measures the light intensity of the target light source and is not affected by other surrounding light sources.

[0045] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the light intensity detection component 60 uses an SM8760 light intensity sensor. The light intensity sensor is used to evaluate the luminous effect of LED beads and detect whether the light intensity of each LED unit meets the standard, thereby determining whether there are defects, such as excessively low or high brightness.

[0046] The specific working process of this utility model is as follows:

[0047] First, the LED bead to be tested is placed in the fixture 80, and an electrical connection is established between the LED bead and the fixture 80. Then, the push plate 520 is moved by the cylinder 510, and the fixture 80 is pushed to slide along the slide rail 550 via the slider 530. During this process, the fixture 80 enters the light shield 30 along the slide rail 550. At the same time, the light intensity test of the LED bead's conduction current is started.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
