Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 The present invention provides an embodiment of an LED assembly module testing device, which is easy to use and includes a main body 1, wherein a lifting mechanism 2 and a support mechanism 3 are provided inside the main body 1.

[0032] Specifically, the main body 1 is the main structure of the testing device, the lifting mechanism 2 controls the up and down movement of the module, and the support mechanism 3 supports and fixes the module.

[0033] Reference Figure 2 , Figure 3 The main body 1 includes a movable base 101 and a wire 105. A test frame 102 is fixedly installed on the upper end of the movable base 101. Acrylic plates 103 are fixedly fitted on the front end and both sides of the test frame 102. A test platform 104 is fixedly installed in the middle position of the upper end of the movable base 101.

[0034] A signal light is fixedly installed on the upper end of the test frame 102 near one side. A data acquisition camera is fixedly installed on the inner top surface of the test frame 102. A fixing frame is fixedly installed on one side of the test frame 102 near the front end. The display screen body is rotatably installed at the front end of the fixing frame. One end of the wire 105 near the upper end is snapped into the first slot 302. The outer surface of the wire 105 is slidably sleeved on the upper end of the test platform 104. The main part of the wire 105 is located inside the test platform 104.

[0035] Specifically, the movable base 101 is a crucial structure in the measuring device. It houses the main electrical control unit, a test control parameter display structure, a digital power supply, and an industrial control box, serving as the control center of the entire testing device. It also supports the upper structure. The lower end of the movable base 101 is equipped with casters for easy movement of the device. The test frame 102 is an outer frame that protects the module and testing structure within it. Acrylic plates 103 are located on both sides and the front end of the test frame 102, with the front-end acrylic plate 103 being shorter and leaving some space at the bottom for easy module transport. The acrylic plates 103 also isolate external light, preventing interference with the photographing effect and ensuring the accuracy of the device's LED bead illumination detection. The test platform 104 contains a circuit structure for transmitting electrical signals. Wires 105 are used for the electrical connection between the test platform 104 and the support plate 301. Signal lights display the test results by color. The acquisition camera takes pictures of the module during testing, and the performance of the module is detected by recognizing the images. The mounting bracket supports the computer, and the main display screen is the structure for the operator to control the testing process.

[0036] Reference Figure 3-5 The lifting mechanism 2 includes a fixed frame 201 and two cylinders 203. Air pumps 202 are fixedly installed at the lower end of the fixed frame 201 near both sides. Piston blocks 204 are slidably sleeved inside the two cylinders 203. Piston rods 205 are fixedly connected to the lower ends of the two piston blocks 204. Rotating blocks 206 are rotatably connected to the lower ends of the two piston rods 205.

[0037] The rear end of the fixed frame 201 is fixedly connected to the inner surface of the test frame 102 near the rear end. The front end of the fixed frame 201 is fixedly connected to one of the three acrylic plates 103 near the middle. The upper ends of the two cylinders 203 are fixedly set at the lower end of the fixed frame 201 near the sides. The output ends of the two air pumps 202 are fixedly connected to the opposite side of the two cylinders 203. The two piston rods 205 are slidably sleeved on the lower end of the two cylinders 203. The two piston rods 205 are sleeved in the two holes 303. The two rotating blocks 206 are located at the lower end of the support plate 301 near the sides.

[0038] Specifically, the air pump 202, cylinder 203, piston block 204, and piston rod 205 together constitute an inverted lifting cylinder. The fixing frame 201 is used to fix the lifting cylinder. The piston block 204 is slidably disposed within the cylinder 203, dividing the cylinder 203 into upper and lower spaces. The output end of the air pump 202 is connected to the space near the upper end, which can change the air pressure in the space, creating a pressure difference between the upper and lower ends of the piston block 204, thereby driving the piston block 204 to slide up and down. The lower end of the piston rod 205 is connected to the rotating block 205 via a spring clamp. 6. Rotary connection: When the rotating block 206 is not subjected to external force, it remains horizontal under the action of the spring clip. At this time, the upper end surface of the rotating block 206 is a plane and the lower end surface is an arc surface. When the plane at the upper end of the rotating block 206 is in contact with the lower end of the support plate 301, it can support the support plate 301. When the rotating block 206 is subjected to external force and rotates to the vertical direction, it and the piston rod 205 form a slender cylinder. At this time, the size of the horizontal cross section is the same as that of the hole 303, and it can easily pass through the hole 303.

[0039] Reference Figure 3 , Figure 5 , Figure 6 The support mechanism 3 includes a support plate 301, a sliding plate 306, and a module body 308. A first slot 302 is provided on one side of the support plate 301 near the front end. Holes 303 are provided on the upper end of the support plate 301 near both sides. A second slot 304 is provided on the inner surface of the support plate 301 near the rear end. Slide grooves 305 are provided on the inner surface of the support plate 301 near both sides. A third slot 307 is provided on the upper end of the sliding plate 306.

[0040] The support plate 301 is located at the upper end of the test platform 104. The two sides of the slide plate 306 are slidably fitted in the two slide grooves 305 respectively. The rear end of the slide plate 306 is engaged in the second slot 304. The module body 308 is located at the upper end of the support plate 301 and the slide plate 306. The lower end of the module body 308 is engaged in the third slot 307.

[0041] Specifically, the support plate 301 is a structure that supports the module body 308. The first slot 302, the second slot 304, and the third slot 307 are all equipped with metal patches. When the slots are engaged with their corresponding structures, electrical connection can be achieved. The size of the hole 303 is the same as the size of the piston rod 205. When the rotating block 206 rotates to the vertical direction, it can slide smoothly through the hole 303. The slide groove 305 allows the slide plate 306 to slide back and forth, which facilitates the delivery of the module to the testing device. When the rear end of the slide plate 306 is engaged with the second slot 304, the two are electrically connected through the metal patch. The LED module to be tested in the module body 308 has a metal protrusion at its lower end, which is connected to the patch in the third slot 307, so that the module and the slide plate 306 can be electrically connected.

[0042] Working principle: When using this testing device, the support plate 301 needs to be installed first. Place the support plate 301 on the test platform 104 and start the air pump 202. The cylinder 203 is divided into upper and lower spaces by the piston block 204. Control the air pump 202 to increase the air pressure in the upper space, which in turn drives the piston block 204 and piston rod 205 to move downward. At this time, the rotating block 206 is in a horizontal state under the action of the spring clamp. When the lower end of the piston rod 205 reaches the hole 303, the piston rod 205 continues to move downward. The limiting effect of the hole 303 causes the rotating block 206 to flip upward until the rotating block 206 rotates to a vertical state. In this way, the piston rod 205 and the rotating block 206 pass smoothly through the hole 303. When the limiting effect of the hole 303 is removed, the elastic force of the spring clamp causes the rotating block 206 to return to its original state. The two piston rods 205 limit the support plate 301. Then, the wire 105 is connected to the first slot 302.

[0043] Next, the module body 308 needs to be transported into the device, and the slide plate 306 is slid outward to engage the protrusion at the lower end of the module body 308 into the third slot 307. This serves two purposes: positioning the module body 308 and connecting the module body 308 and the slide plate 306 with electrical wires. The slide plate 306 is then pushed backward so that its rear end engages with the second slot 304. Through the engagement of the three slots, the electrical connection between the module body 308 and the control circuit can be completed.

[0044] Finally, the air pump 202 is started, which reduces the air pressure in the upper part of the cylinder 203. The pressure difference causes the piston block 204 and piston rod 205 to move upward. The two horizontal rotating blocks 206 support the support plate 301, which in turn moves the support plate 301 and the module body 308 upward until they reach the area blocked by the acrylic plate 103 for subsequent testing.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
