Description

Technical Field

[0001] This invention relates to the field of light-emitting diode (LED) detection, and particularly to a detection device for LEDs. Background Technology

[0002] A light-emitting diode (LED) is a semiconductor electronic device that directly converts electrical energy into light energy. Its core is a semiconductor PN junction. When a forward voltage is applied, electrons and holes recombine, releasing energy in the form of photons, thus emitting visible or non-visible light. The core of an LED detection device is a simple circuit that provides an appropriate current. During testing, the long and short leads of the LED are correctly connected to the corresponding polarity interfaces of the device. If the LED is intact, the forward current provided by the device will cause its internal semiconductor junction to conduct and emit light, thus visually indicating that the LED is functioning normally. If the LED is damaged, it will not emit light regardless of the polarity, thus identifying the faulty product.

[0003] However, existing LED testing devices usually require users to strictly distinguish between long and short pins, i.e., the insertion direction of the positive and negative pins. If they are inserted in reverse, it may result in a circuit failure leading to test failure, or even damage to the diode or the testing equipment, increasing the complexity of operation and the risk of misoperation. Summary of the Invention

[0004] The main objective of this invention is to provide a detection device for light-emitting diodes, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A detection device for light-emitting diodes includes a detection body, a light-emitting crystal disposed on the top of the detection body, fixed suction cups fixedly connected to the four corners of the bottom of the detection body, an energized groove disposed on the side of the detection body, a long pin and a short pin disposed on the bottom of the light-emitting crystal, three adaptive detection structures equidistantly disposed inside the detection body, each adaptive detection structure including two energized sliders, a pair of placement slots opened inside the detection body, and a through groove opened through the top of the detection body through both placement slots.

[0007] Two power contacts are provided on both sides of the power-conducting slider. A power-conducting slot is opened through the top of the power-conducting slider. A spring is fixedly connected inside the slot and at the bottom of the power-conducting slider.

[0008] As a further embodiment of the present invention, an energizing block is fixedly connected inside the detection body and on the opposite side of each pair of placement slots, and a pair of series blocks are fixedly connected inside the detection body and on the opposite side of each pair of placement slots. Two energizing contacts are also provided on both sides of the series blocks and on one side of the energizing block.

[0009] As a further embodiment of the present invention, both the long pins and the short pins are adapted to the power-on slot, and the power-on slider is adapted to the placement slot.

[0010] As a further aspect of the present invention, each pair of energized blocks is connected by a series line, all series lines are connected by a parallel line, the interior of the parallel line is fixedly connected to the outer surface by an input line, the input line is connected to the energized slot, and each pair of series blocks is connected by a connecting wire.

[0011] As a further embodiment of the present invention, the detection body is provided with three self-locking structures equidistantly arranged inside. Each self-locking structure includes several inserts, which are slidably connected to the inside of the placement slot. A connecting rod is fixedly connected to the side of the insert, and a stop block is fixedly connected to the outer surface of the connecting rod. The stop block is slidably connected to the detection body. A second spring is fixedly connected between the inside of the detection body and the side of the stop block. A fixing cover is fixedly connected to the top of each energized slider on both sides. A fixing rod is fixedly connected between the top of the energized slider and the inside of the fixing cover. A base block is fixedly connected to the outer surface of the fixing rod. A lever is slidably connected to the outer surface of the fixing rod and the top of the base block. A connecting sleeve is fixedly connected to the top of the lever. A third spring is fixedly connected between the bottom of the lever and the top of the base block.

[0012] As a further embodiment of the present invention, a pair of cylindrical grooves are symmetrically provided inside the detection body and at the top of each placement groove, and the cylindrical grooves are adaptively matched with the fixing cover.

[0013] As a further embodiment of the present invention, the top and bottom of the dial block are both inclined, and the top of the insert block is also inclined, with the inclined surfaces of the dial block and the insert block being adaptively matched.

[0014] As a further embodiment of the present invention, a top groove is provided inside the fixed cover through the top, and the top groove is adaptively matched with the insert block.

[0015] As a further embodiment of the present invention, the three adaptive detection structures are connected in parallel with each other, and the energized slider is electrically connected to the energized block and the series block through energized contacts.

[0016] As a further embodiment of the present invention, the long pin and the short pin are electrically connected through a power-on slot.

[0017] The beneficial effects of this invention are as follows:

[0018] By setting an adaptive detection structure, regardless of how the insertion positions of long and short pins are reversed, the energized slider can automatically connect to the corresponding energized block and series block by sliding up and down, ensuring that the circuit is always correctly conductive, thereby avoiding detection failures caused by polarity errors. This not only simplifies the user's operation process, eliminating the need for manual pin orientation, but also improves detection efficiency and reliability, reduces false detection rate, and the buffer design of spring one ensures the stability of electrical contact, extends the service life of the device, and is suitable for batch rapid detection scenarios.

[0019] By setting energized contacts, the energized slider can be quickly and electrically connected to the series block and the energized block. By using the direct contact of the contacts to conduct electricity, the need for complex guiding mechanisms or additional connecting wires to ensure the circuit connection between the energized slider and the series block and the energized block is avoided, making the internal structure relatively simple. At the same time, the required electrical connectivity is reliably achieved through multi-point contact, ensuring the performance of the detection circuit.

[0020] By setting a self-locking structure, when the energized slider slides down to the position, the insert block automatically inserts into the top groove of the fixing cover under the rebound force of the second spring, and is locked at the bottom of the bottom block and the bottom of the push block. This automatic mechanical locking mechanism makes the energized slider firmly fixed, eliminating the need for the operator to continuously apply downward pressure, significantly reducing operator fatigue, and is especially suitable for batch testing scenarios.

[0021] The locked state effectively prevents the energized slider from moving upward or shaking due to slight external force or vibration during the testing process. This ensures that the contact pressure between the metal contacts and the energized block and series block is constant, avoiding fluctuations or misjudgments in test results due to poor contact, such as unstable light emission, and greatly improving the accuracy and reliability of the test results.

[0022] When the insert is successfully inserted into the top slot, a clear mechanical locking sensation or sound will be produced, providing the operator with intuitive physical feedback that it is "locked and connected," preventing over-insertion. Unlocking and ejection are achieved through a single, continuous pressing action, thus speeding up the batch testing process. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figure 1 - Figure 10As shown, a detection device for light-emitting diodes includes a detection body 1, a light-emitting crystal 2 disposed on the top of the detection body 1, fixed suction cups 4 fixedly connected to the four corners of the bottom of the detection body 1, an electric groove 3 disposed on the side of the detection body 1, a long pin 6 and a short pin 7 disposed on the bottom of the light-emitting crystal 2, three adaptive detection structures 5 disposed at equal intervals inside the detection body 1, each adaptive detection structure 5 including two electric sliders 10, a pair of placement grooves 9 opened inside the detection body 1, and a through groove 8 opened through the top of the detection body 1 through the interior of both placement grooves 9;

[0036] Two power contacts 12 are provided on both sides of the power slider 10. The top of the power slider 10 has a power contact that is inserted into the power slot 11. A spring 13 is fixedly connected inside the slot 9 and at the bottom of the power slider 10.

[0037] First, the light-emitting crystal 2, long pin 6, and short pin 7 together constitute a light-emitting diode. The external adapter is plugged into the power supply slot 3, and then the adapter plug is connected to an external power source. Next, the light-emitting diode is inserted into the detection body 1 through the two through slots 8. After the long pin 6 is inserted into the placement slot 9 through the through slot 8, it connects to the power supply slot 11, causing the power supply slider 10 to slide down the placement slot 9, compressing the spring 13. The movement trajectory of the short pin 7 is similar. When the power supply slider 10 reaches the bottom, it connects to the bottom-mounted power supply block 14 and the bottom-mounted series connection via the power supply contact 12. When block 15 is electrically connected, the energized slider 10 connected to the short pin 7 is located at the top of the placement slot 9, and is electrically connected to the energized block 14 near the top and the series block 15 near the top through the energized contact 12. Therefore, the long pin 6 and the short pin 7 are electrically connected through the two series blocks 15. The two energized blocks 14, which are at different heights, are electrically connected to the main circuit. Therefore, the current can flow normally through the long pin 6 and the short pin 7, so that the light-emitting crystal 2 can emit light normally. If it cannot emit light normally, the light-emitting diode is faulty, and thus the power-on detection process is completed.

[0038] As the long pin 6 drives the energized slider 10 to slide up and down along the inside of the placement slot 9, when the energized slider 10 slides to the position of the bottom series block 15, the energized slider 10 is electrically connected to the bottom energized block 14 and the bottom series block 15. The short pin 7 drives another energized slider 10 to be electrically connected to the top energized block 14 and the top series block 15. When the insertion positions of the long pin 6 and the short pin 7 are reversed, the same principle applies, and it can still be connected to the main circuit. Therefore, no matter how the insertion positions of the long pin 6 and the short pin 7 are reversed, the energized slider 10 can automatically connect to the corresponding energized block 14 and series block 15 by sliding up and down, ensuring that the circuit is always correctly conductive, thereby avoiding detection failure due to polarity error. This not only simplifies the user's operation process, eliminating the need for manual differentiation of pin direction, but also improves detection efficiency and reliability, reduces the false detection rate, and the buffer design of spring 13 ensures the stability of electrical contact and extends the service life of the device, making it suitable for batch rapid detection scenarios.

[0039] In this embodiment, an energizing block 14 is fixedly connected inside the detection body 1 and on the opposite side of each pair of placement slots 9. A pair of series blocks 15 are fixedly connected inside the detection body 1 and on the opposite side of each pair of placement slots 9. Two energizing contacts 12 are also provided on both sides of the series blocks 15 and on one side of the energizing block 14.

[0040] The energized contact 12 enables the energized slider 10 to be quickly and electrically connected to the series block 15 and the energized block 14. By using the direct contact of the contacts to conduct electricity, the need for complex guiding mechanisms or additional connecting wires to ensure the circuit connection between the energized slider 10 and the series block 15 and the energized block 14 is avoided, making the internal structure relatively simple. At the same time, the required electrical connectivity is reliably achieved through multi-point contact, ensuring the performance of the detection circuit.

[0041] In this embodiment, both the long pin 6 and the short pin 7 are compatible with the power-on slot 11, and the power-on slider 10 is compatible with the placement slot 9.

[0042] In this embodiment, each pair of energized blocks 14 is connected by a series line 17, and all series lines 17 are connected by a parallel line 18. The parallel line 18 is fixedly connected to an input line 19 through its outer surface. The input line 19 is connected to the energized slot 3. Each pair of series blocks 15 is connected by a connecting wire 16. When the long pin 6 and the short pin 7 are electrically connected, there is a distance between the bottom of the light-emitting crystal 2 and the top of the detection body 1.

[0043] In this embodiment, three self-locking structures 20 are equidistantly arranged inside the detection body 1. Each self-locking structure 20 includes several insert blocks 23. The insert blocks 23 are slidably connected to the inside of the placement slot 9. A connecting rod 22 is fixedly connected to the side of the insert block 23. A stop block 24 is fixedly connected to the outer surface of the connecting rod 22. The stop block 24 is slidably connected to the detection body 1. A spring 25 is fixedly connected between the inside of the detection body 1 and the side of the stop block 24. A fixing cover 21 is fixedly connected to the top of each energized slider 10 near both sides. A fixing rod 26 is fixedly connected between the top of the energized slider 10 and the inside of the fixing cover 21. A base block 28 is fixedly connected to the outer surface of the fixing rod 26. A lever 27 is slidably connected to the outer surface of the fixing rod 26 and the top of the base block 28. A connecting sleeve 29 is fixedly connected to the top of the lever 27. A spring 30 is fixedly connected between the bottom of the lever 27 and the top of the base block 28.

[0044] When the energized slider 10 slides down, it causes a pair of fixed covers 21 to move down. The bottom of the energized slider 10 will press against the insert 23, causing the insert 23 to move horizontally. As a result, the insert 23 is no longer located inside the placement slot 9. When the fixed cover 21 moves to the position of the insert 23, the insert 23 is inserted into the top slot 32 under the action of the spring 25 and is located at the bottom of the bottom block 28 and the toggle block 27. At this time, if the energized slider 10 is to be moved up, the bottom of the top slot 32 will press against the bottom plane of the insert 23, and the insert 23 cannot move horizontally. Therefore, in this state, the energized slider 10 can be firmly fixed under the action of the upward movement restricted by the insert 23 and the upward rebound force of the spring 13. This makes it unnecessary to continuously press down on the light-emitting diode during electrical connection and can avoid the light-emitting diode from shaking during electrical connection, which would lead to unstable connection.

[0045] When it is necessary to release the fixing effect of the energized slider 10, continue to move the energized slider 10 downwards. The top of the connecting sleeve 29 is pressed against the top position of the inside of the fixing cover 21, which prevents the toggle block 27 from moving upwards. Therefore, the bottom of the toggle block 27 is pressed against the top inclined surface of the insert block 23, so that the toggle block 27 is no longer located inside the placement groove 9. At this time, the energized slider 10 can move downwards until the toggle block 27 moves to the bottom of the insert block 23. Under the rebound force of the second spring 25, the insert block 23 is placed back inside the placement groove 9. At this time, the energized slider 10 moves upwards under the action of the first spring 13, so that the bottom of the insert block 23 is pressed against the top of the toggle block 27, and then the insert block 23 moves horizontally under the top inclined surface of the toggle block 27. Therefore, the insert block 23 is no longer located inside the placement groove 9. At this time, the energized slider 10 can continue to move upwards until it is completely reset.

[0046] In this embodiment, a pair of cylindrical grooves 31 are symmetrically provided inside the detection body 1 and at the top of each placement groove 9. The cylindrical grooves 31 are adaptively matched with the fixing cover 21.

[0047] In this embodiment, the top and bottom of the toggle block 27 are both inclined, and the top of the insert block 23 is also inclined. The inclined surfaces of the toggle block 27 and the insert block 23 are compatiblely matched.

[0048] In this embodiment, a top groove 32 is provided inside the fixed cover 21 through the top, and the top groove 32 is adaptively matched with the insert block 23.

[0049] In this embodiment, the three adaptive detection structures 5 are connected in parallel, and the energized slider 10 is electrically connected to the energized block 14 and the series block 15 through the energized contact 12.

[0050] In this embodiment, the long pin 6 and the short pin 7 are electrically connected to the power socket 11 when energized.

[0051] It should be noted that this invention is a detection device for light-emitting diodes (LEDs). In use, the LED is formed by the LED itself, consisting of the LED crystal 2, long pin 6, and short pin 7. An external adapter is plugged into the power supply slot 3, and then the adapter plug is connected to an external power source. The LED is then inserted into the detection body 1 through the two through slots 8. After the long pin 6 is inserted into the placement slot 9 through the through slot 8, it engages with the power supply slot 11, causing the power supply slider 10 to slide down the placement slot 9. The spring 13 is compressed. The movement trajectory of the short pin 7 is similar. When the power supply slider 10 reaches the bottom, it connects to the contact point 12. The bottom energizing block 14 and the bottom series block 15 are electrically connected. At this time, the energizing slider 10 connected to the short pin 7 is located at the top of the placement slot 9 and is electrically connected to the top energizing block 14 and the top series block 15 through the energizing contact 12. Therefore, the long pin 6 and the short pin 7 are electrically connected through the two series blocks 15. The two energizing blocks 14, which are at different heights, are electrically connected to the main circuit. Therefore, the current can flow normally through the long pin 6 and the short pin 7, so that the light-emitting crystal 2 can emit light normally. If it cannot emit light normally, the light-emitting diode is faulty, and the power-on detection process is completed.

[0052] As the long pin 6 drives the energized slider 10 to slide up and down along the inside of the placement slot 9, when the energized slider 10 slides to the position of the bottom series block 15, the energized slider 10 is electrically connected to the bottom energized block 14 and the bottom series block 15. The short pin 7 drives another energized slider 10 to be electrically connected to the top energized block 14 and the top series block 15. When the insertion positions of the long pin 6 and the short pin 7 are reversed, the same principle applies, and it can still be connected to the main circuit. Therefore, no matter how the insertion positions of the long pin 6 and the short pin 7 are reversed, the energized slider 10 can automatically connect to the corresponding energized block 14 and series block 15 by sliding up and down, ensuring that the circuit is always correctly conductive, thereby avoiding detection failure due to polarity error. This not only simplifies the user's operation process, eliminating the need for manual differentiation of pin direction, but also improves detection efficiency and reliability, reduces the false detection rate, and the buffer design of spring 13 ensures the stability of electrical contact and extends the service life of the device, making it suitable for batch rapid detection scenarios.

[0053] The energized contact 12 enables the energized slider 10 to be quickly and electrically connected to the series block 15 and the energized block 14. By using the direct contact of the contact points to conduct electricity, the need for complex guiding mechanisms or additional connecting wires to ensure the circuit connection between the energized slider 10 and the series block 15 and the energized block 14 is avoided, making the internal structure relatively simple. At the same time, the required electrical connectivity is reliably achieved through multi-point contact, ensuring the performance of the detection circuit.

[0054] When the energized slider 10 slides down, it causes a pair of fixed covers 21 to move down. The bottom of the energized slider 10 will press against the insert 23, causing the insert 23 to move horizontally. As a result, the insert 23 is no longer located inside the placement slot 9. When the fixed cover 21 moves to the position of the insert 23, the insert 23 is inserted into the top slot 32 under the action of the spring 25 and is located at the bottom of the bottom block 28 and the toggle block 27. At this time, if the energized slider 10 is to be moved up, the bottom of the top slot 32 will press against the bottom plane of the insert 23, and the insert 23 cannot move horizontally. Therefore, in this state, the energized slider 10 can be firmly fixed under the action of the upward movement restricted by the insert 23 and the upward rebound force of the spring 13. This makes it unnecessary to continuously press down on the light-emitting diode during electrical connection and can avoid the light-emitting diode from shaking during electrical connection, which would lead to unstable connection.

[0055] When it is necessary to release the fixing effect of the energized slider 10, continue to move the energized slider 10 downwards. The top of the connecting sleeve 29 is pressed against the top position of the inside of the fixing cover 21, which prevents the toggle block 27 from moving upwards. Therefore, the bottom of the toggle block 27 is pressed against the top inclined surface of the insert block 23, so that the toggle block 27 is no longer located inside the placement groove 9. At this time, the energized slider 10 can move downwards until the toggle block 27 moves to the bottom of the insert block 23. Under the rebound force of the second spring 25, the insert block 23 is placed back inside the placement groove 9. At this time, the energized slider 10 moves upwards under the action of the first spring 13, so that the bottom of the insert block 23 is pressed against the top of the toggle block 27, and then the insert block 23 moves horizontally under the top inclined surface of the toggle block 27. Therefore, the insert block 23 is no longer located inside the placement groove 9. At this time, the energized slider 10 can continue to move upwards until it is completely reset.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
