[0002] Two-in-one LED technology is an innovative display technology that optimizes the combination of traditional LED lamp beads and achieves higher display effects and efficiency by merging two LED units into one.

[0003] In traditional two-in-one LED testing equipment, the use of a vibration plate for loading can easily cause the two-in-one LED workpiece to flip during transportation, making it impossible to ensure that the two test parts of each two-in-one LED are in the same position when collecting photoelectric parameters. In addition, the material size of the two-in-one LED is large, and positional displacement is prone to occur during the output process. Traditional two-in-one LED testing equipment uses a single integrating sphere aligned with the center of the entire two-in-one LED for photoelectric collection, which can easily lead to deviations in the test results and affect the test results.

[0034] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a two-in-one semiconductor material testing device, comprising the following steps:

[0035] Step 1: The vibration plate loader drives the two-in-one LED test workpiece to the loading station, and then the driving motor drives the active synchronous pulley to rotate, and the rotation of the active synchronous pulley drives the driven synchronous pulley to rotate synchronously through the synchronous belt; the rotation of the active synchronous pulley and the driven synchronous pulley drives the two rocker arms to swing; the driving motor drives the active synchronous pulley and the driven synchronous pulley to continuously and synchronously rotate forward and backward, so that the two rocker arms drive the fixed block to continuously swing left and right; when the fixed block is at the right swing stop point, the vacuum suction head is aligned with the discharge port of the vibration plate loader; then the vacuum suction head works to adsorb and fix the two-in-one LED test workpiece; then when the fixed block swings to the left to the left swing stop point, the vacuum suction head is aligned with the placement block at the loading station; then the vacuum suction head places the two-in-one LED test workpiece on the placement block;

[0036] When the cam is in the air, the push plate is pushed back and the sliding block is released, and the cam is released to move the cam inwards, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air, and the cam is in the air

[0037] Step 3: After the adjustment is completed, the cylinder works again to drive the push plate to move and separate the fixed centering clamp and the movable centering clamp. Then the electric rotary disk works to drive the two-in-one LED test workpiece with completed position adjustment to move to the first test station.

[0038] Then, the servo motor of the first test component works to drive the connecting block to rotate, and the rotation of the connecting block pulls the first connecting rod and the second connecting rod to rotate together, and the first connecting rod pushes the mounting plate of the first conductive test component to follow the sliding block two to move backward along the guide rail two; the second connecting rod pulls the mounting plate of the second conductive test component to follow the sliding block two to move forward along the guide rail two; until the conductive test needles installed on the mounting plates of the first conductive test component and the second conductive test component contact the front and rear ends of the left side of the two-in-one LED test workpiece, and then the conductive test needles can work to perform a conductive test on the left part of the two-in-one LED test workpiece, so as to determine the conductive polarity of the left part of the two-in-one LED test workpiece; and the integrating sphere installed on the guide rail two of the first test component will collect photoelectric parameters with the left side of the two-in-one LED test workpiece as the center; when the left part of the two-in-one LED test workpiece completes the conductive performance test, the conductive polarity of the left part of the two-in-one LED test workpiece is used to determine whether the left part of the two-in-one LED test workpiece is the first test part or the second test part;

[0039] Step 4: Similarly, when the electric rotating disk drives the two-in-one LED test workpiece to the second test station, the conductive test component of the second test assembly will perform a conductive test on the right side of the two-in-one LED test workpiece to determine the conductive polarity of the right side of the two-in-one LED test workpiece. The integrating sphere of the second test assembly will also collect photoelectric parameters centered on the right side of the two-in-one LED test workpiece.

[0040] If the left side of the two-in-one LED test workpiece is determined to be the first test section by the conductive polarity test result at the first test station, then the right side of the two-in-one LED test workpiece is the second test section. Conversely, if the left side of the two-in-one LED test workpiece is determined to be the second test section by the conductive polarity test result at the first test station, then the right side of the two-in-one LED test workpiece is the first test section.

[0041] Step 5: The device then automatically adjusts the photoelectric parameter collection data results of the first test station and the second test station so that the data of the first test part is in front and the data of the second test part is in the back;

[0042] Step 6: The electric rotating disk then drives the two-in-one LED test workpiece that has completed the test to move to the unloading station; then the blowing nozzle blows the two-in-one LED test workpiece with different photoelectric parameter collection data into the corresponding receiving tube.

[0043] Compared with the prior art, the present invention has the following beneficial effects: through the cooperation of the first test component and the second test component, different integrating spheres are always centered on the left or right side of the two-in-one LED test workpiece to collect photoelectric parameters, thereby reducing test deviation, and the photoelectric parameter collection results of the first test station and the second test station can be automatically adjusted to the data of the first test part in front and the data of the second test part in the back, thereby ensuring the uniformity of the test and improving the quality of material distribution; through the continuous material shifting mechanism, continuous loading of the two-in-one LED test workpiece can be achieved, thereby improving the test efficiency of the device; through the automatic centering position adjustment mechanism, the position of the two-in-one LED test workpiece is adjusted before testing, so that it is strictly aligned with the central axis of the placement block, thereby avoiding measurement errors caused by eccentricity or angular deviation, thereby further reducing test deviation; through the cooperation of the material distribution mechanism and the material receiving tube, the device can quickly and accurately classify and distribute materials according to preset rules, thereby reducing the need for manual operation and improving the operating speed and overall efficiency of the test line.

[0056] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0058] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-9A two-in-one semiconductor material testing device includes a base 1, a vibration plate loader 2, a continuous material moving mechanism 3, an electric rotating plate 4, an automatic centering position adjustment mechanism 5, a double-station separation electrical test mechanism 6, a material dividing mechanism 7, a two-in-one LED test workpiece 8 and a material receiving tube 9; the vibration plate loader 2 is fixedly installed on the right side of the upper end of the base 1; the electric rotating plate 4 is fixedly installed in the middle of the upper end of the base 1; and a plurality of placement blocks 41 are fixedly installed on the movable end of the electric rotating plate 4; the placement blocks 41 are evenly distributed in a circular array at equal intervals on the movable end of the electric rotating plate 4;

[0059] The right side of the electric rotating disk 4 is set as the loading station; the right side of the front side of the electric rotating disk 4 is set as the centering station; the front side of the electric rotating disk 4 is set as the first testing station; the left side of the front side of the electric rotating disk 4 is set as the second testing station; the left side of the electric rotating disk 4 is set as the material separation station;

[0060] The loading station is equipped with a continuous material transfer mechanism 3 for moving the two-in-one LED test workpieces 8 at the discharge port of the vibration plate loader 2 one by one to the placement block 41 at the loading station; and the continuous material transfer mechanism 3 is installed at the upper end of the base 1;

[0061] An automatic centering position adjustment mechanism 5 is installed at the centering station for adjusting the position of the two-in-one LED test workpiece 8 on the centering station placement block 41; and the automatic centering position adjustment mechanism 5 is installed at the upper end of the base 1;

[0062] A double-station separation conductivity test mechanism 6 for performing separation conductivity test on a two-in-one LED test workpiece 8 is installed on the front side of the upper end of the base 1;

[0063] like Figure 4 As shown, the dual-station separation conductivity test mechanism 6 includes a first test component and a second test component; the first test component and the second test component have the same structure; the first test component is used to perform a conductivity test on one side of the two-in-one LED test workpiece 8; the second test component is used to perform a conductivity test on the other side of the two-in-one LED test workpiece 8; and the first test component is set at the first test station; the second test component is set at the second test station;

[0064] A material distribution mechanism 7 is installed on the left side of the upper end of the base 1 for controlling the movement of the two-in-one LED test workpiece 8 into different receiving tubes 9 according to the test results of the first test component and the second test component; multiple receiving tubes 9 are installed on the material distribution mechanism 7;

[0065] In the present invention, the vibration plate loader 2 drives the two-in-one LED test workpiece 8 to move to the loading station, and then the continuous material transfer mechanism 3 works to transfer the two-in-one LED test workpiece 8 to the placement block 41 of the loading station; the electric rotary plate 4 works to drive the placement block 41 to rotate to the centering station; then the automatic centering position adjustment mechanism 5 works to adjust the position of the two-in-one LED test workpiece 8 on the placement block 41 so that the two-in-one LED test workpiece 8 is located at the center of the upper end of the placement block 41; after completing the centering posture adjustment, the electric rotary plate 4 continues to work to drive the placement block 41 to move to the first test station;

[0066] After the placement block 41 drives the two-in-one LED test workpiece 8 to move to the first test station, the electric rotary disk 4 stops operating; and at this time, the first test component is aligned with the left side of the two-in-one LED test workpiece 8. Subsequently, the first test component operates to test the electrical conductivity of the left side of the two-in-one LED test workpiece 8 and collects photoelectric parameters;

[0067] Since the two-in-one LED test workpiece 8 is loaded by the vibration plate loader 2, the two-in-one LED test workpiece 8 may turn over during transportation. Therefore, it is impossible to ensure that the first test portion 81 of the two-in-one LED test workpiece 8 is always on the left side and the second test portion 82 of the two-in-one LED test workpiece 8 is always on the right side; and the first test portion 81 and the second test portion 82 have different conductive polarities.

[0068] After the left side of the two-in-one LED test workpiece 8 has completed the conductivity test, it is determined whether the left side of the two-in-one LED test workpiece 8 is the first test portion 81 or the second test portion 82 according to the conductive polarity of the left side of the two-in-one LED test workpiece 8;

[0069] Then, the electric rotary disk 4 starts to work again, driving the placement block 41 to move to the second test station. The electric rotary disk 4 stops running, and the second test component is aligned with the right side of the two-in-one LED test workpiece 8. Then, the second test component starts to work to test the conductivity and collect photoelectric parameters of the right side of the two-in-one LED test workpiece 8.

[0070] If the left side of the two-in-one LED test workpiece 8 is determined to be the first test section 81 by the conductive polarity test result at the first test station, then the right side of the two-in-one LED test workpiece 8 is the second test section 82. Conversely, if the left side of the two-in-one LED test workpiece 8 is determined to be the second test section 82 by the conductive polarity test result at the first test station, then the right side of the two-in-one LED test workpiece 8 is the first test section 81.

[0071] Then the device automatically adjusts the photoelectric parameter acquisition data results of the first test station and the second test station so that the data of the first test part 81 is in front and the data of the second test part 82 is in the back;

[0072] Then, the electric rotating disk 4 drives the two-in-one LED test workpiece 8 that has completed the test to move to the unloading station; then the dividing mechanism 7 blows the two-in-one LED test workpiece 8 with different types of photoelectric parameter collection data into the corresponding receiving tube 9; repeating the above operation can achieve the classification and accurate testing and collection of the two-in-one LED test workpiece 8;

[0073] By cooperating with the first test component and the second test component, different integrating spheres are always centered on the left or right side of the two-in-one LED test workpiece 8 to collect photoelectric parameters, thereby reducing test deviation. In addition, the photoelectric parameter collection results of the first test station and the second test station can be automatically adjusted to the data of the first test part 81 in front and the data of the second test part 82 in the back, thereby ensuring the uniformity of the test and improving the quality of material distribution. By means of the continuous material moving mechanism 3, continuous loading of the two-in-one LED test workpiece 8 can be achieved, thereby improving the test efficiency of the device. By means of the automatic centering position adjustment mechanism 5, the position of the object to be tested of the two-in-one LED test workpiece 8 is adjusted before testing, so that it is strictly aligned with the central axis of the placement block 41, thereby avoiding measurement errors caused by eccentricity or angular deviation, thereby further reducing test deviation. By means of the cooperation of the material distribution mechanism 7 and the material receiving tube 9, the device can quickly and accurately classify and distribute materials according to preset rules, thereby reducing the need for manual operation and improving the operating speed and overall efficiency of the test line.

[0104] Step 2: Then the cylinder 51 works to push the push plate 52 to follow the sliding block 157 of the vertical moving component and slide downward along the guide rail 156 until the lower end of the push plate 52 contacts the end close to the fixed centering clamp 53 and the movable centering clamp 54; the push plate 52 will push the movable centering clamp 54 to follow the sliding block 157 of the horizontal moving component and slide outward along the guide rail 156; during the sliding process, the movable centering clamp 54 will also stretch the reset spring 55 outward; until the electric rotating disk 4 works to drive the placement block 41 to move to the centering position; and at this time the two-in-one LED test workpiece 8 is located between the fixed centering clamp 53 and the movable centering clamp 54; then the cylinder 51 drives the push plate 52 to reset upward, and the push plate 52 is separated from the fixed centering clamp 53 and the movable centering clamp 54, and then the reset spring 55 recovers and drives the movable centering clamp 54 to move inward and reset. During the movement, the movable centering clamp 54 will contact the two-in-one LED test workpiece 8 and drive the two-in-one LED test workpiece 8 to contact the fixed centering clamp 53; under the action of the fixed centering clamp 53 and the movable centering clamp 54, the position of the two-in-one LED test workpiece 8 can be adjusted;

Furthermore, the integrating sphere mounted on the second first test assembly rail 68 collects photoelectric parameters centered on the left side of the two-in-one LED test workpiece 8. After the conductivity test on the left side of the two-in-one LED test workpiece 8 is completed, the conductive polarity of the left side of the two-in-one LED test workpiece 8 is used to determine whether the left side of the two-in-one LED test workpiece 8 is the first test portion 81 or the second test portion 82.

[0107] Step 4: Similarly, when the electric rotating disk 4 drives the two-in-one LED test workpiece 8 to the second test station, the conductive test component of the second test assembly performs a conductive test on the right side of the two-in-one LED test workpiece 8 to determine the conductive polarity of the right side of the two-in-one LED test workpiece 8; and the integrating sphere of the second test assembly collects photoelectric parameters centered on the right side of the two-in-one LED test workpiece 8;

Conversely, if the left side of the two-in-one LED test workpiece 8 is determined to be the second test section 82 by the conductive polarity test result at the first test station, then the right side of the two-in-one LED test workpiece 8 is the first test section 81.
