Description

Technical Field

[0001] This utility model relates to the technical field of diode testing devices, specifically a conductivity testing device for diode production. Background Technology

[0002] A diode is an electronic device made of semiconductor materials. It has unidirectional conductivity, meaning that when a forward voltage is applied to the anode and cathode of the diode, the diode conducts, and when a reverse voltage is applied to the anode and cathode, the diode is cut off. Diodes have a wide range of applications, especially in various electronic circuits. By using diodes in combination with components such as resistors, capacitors, and inductors, circuits with different functions can be constructed to achieve various functions such as AC rectification, modulation signal detection, amplitude limiting and clamping, and voltage regulation of power supply.

[0003] During the production of diodes, their conductivity characteristics need to be checked to determine whether the products are qualified before packaging and shipping. The current common testing method is to conduct random inspections at a certain ratio. During the random inspection, the testers need to connect the positive and negative terminals of the LED to the positive and negative terminals of a multimeter twice in reverse order to test its forward and reverse resistance and record the test data. However, in actual operation, because the wires at both ends of the diode are thin and the tip of the multimeter probe is thin and long, it is difficult to ensure the stability of the connection between the diode wires and the multimeter pointer. This makes the data prone to change during the test, which not only increases the difficulty of the test but also affects the accuracy of the test. Therefore, we propose a conductivity testing device for diode production. Utility Model Content

[0004] The main objective of this invention is to provide a conductivity testing device for diode production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conductivity testing device for diode production, comprising a test platform, a multimeter nested on one side surface of the test platform, an adjustment groove laterally formed on the upper surface of the test platform, a first test head and a second test head slidably mounted at both ends of the upper surface of the adjustment groove, each of the first and second test heads comprising a sliding seat, a test cavity, an electrode plate, and a connecting slider, sliding seats slidably mounted on both sides of the upper surface of the adjustment groove, test cavities formed at corresponding positions on the opposing surfaces of the sliding groove, an electrode plate detachably connected to the bottom end of the test cavity, a connecting slider fixedly connected to the bottom end of the sliding seat, and a threaded hole laterally formed at the center of the connecting slider, a positive test line and a negative test line respectively provided on the surface of the multimeter, and the ends of the positive and negative test lines electrically connected to motor plates provided in the inner cavities of the first and second test heads, respectively, and a driving assembly for driving the first and second test heads to slide within the inner cavity of the adjustment groove.

[0006] Preferably, the drive assembly includes an adjusting screw and an adjusting end. The adjusting screw is rotatably mounted in the inner cavity of the adjusting groove, and the connecting slider is threadedly connected to both ends of the adjusting screw through a threaded hole. The adjusting end is rotatably nested on the test platform surface on one side of the adjusting screw, and the end of the adjusting end is fixedly connected to one side of the adjusting screw.

[0007] Preferably, the adjusting screw is a double-threaded screw, and the adjusting screw surface has opposing threads on both sides.

[0008] Preferably, the sliding seat at the end of the test chamber has a storage groove, a protective block is slidably disposed in the storage groove, a threaded connection hole is horizontally opened on the back of the storage groove, a threaded connection rod is threadedly connected to the inner cavity of the threaded connection hole, a rotating connection shaft is fixedly connected to the inner side of the threaded connection rod, and the rotating connection shaft is rotatably connected to the back of the protective block.

[0009] Preferably, each threaded connecting rod has a hand-tightening head fixedly connected to its end, and the surface of the hand-tightening head is provided with anti-slip texture.

[0010] Preferably, the lower surface of the protective block is attached to the upper surface of the electrode sheet, and the protective block is adapted to the detection cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes an adjusting end, adjusting groove, adjusting screw, sliding seat, test chamber, and electrode plate, along with a connecting slider, multimeter, positive and negative test leads, to achieve rapid connection between the diode's positive and negative terminals and the multimeter's positive and negative terminals during testing. The lead wires at both ends of the diode are placed directly into the test chamber and contacted with the electrode plate at the bottom of the chamber, ensuring stable contact and improving test accuracy. During testing, the adjusting end can be rotated as needed, causing the adjusting screw to rotate accordingly. As the screw rotates, the connecting slider moves along the axial direction of the adjusting screw within the adjusting groove, allowing the first and second test heads to slide synchronously and stably in opposite or the same direction. This allows for precise adjustment of the distance between the two test heads according to the electrode spacing of diodes of different sizes. Whether it's fine-tuning the spacing of small diodes or adapting to larger spacing of large diodes, the process can be completed quickly and accurately, significantly improving the applicability for conductivity testing of various diodes, effectively reducing test preparation time, and enhancing overall test efficiency.

[0013] 2. This utility model has a storage groove in the inner cavity of the sliding seat at the end of the test chamber. A protective block is slidably connected in the storage groove. When the test head is not in use or during transportation or movement of the equipment, the position of the protective block can be adjusted by rotating the threaded connecting rod. The threaded connecting rod is rotatably connected to the back of the protective block through a rotating connecting shaft. Rotating the hand-tightening head causes the threaded connecting rod to rotate in the threaded connecting hole, thereby pushing the protective block out of the storage groove until the lower surface of the protective block is tightly attached to the upper surface of the motor plate. This allows the protective block to provide good protection for the motor plate, preventing it from being contaminated by dust and debris during daily use, as well as from being damaged in accidental collisions. This extends the service life of the motor plate and ensures the stability and reliability of the test head during long-term use, thereby ensuring the accuracy of the diode conductivity test results.

A connecting slider 86 is fixedly connected to the bottom of the sliding seat 81, and a threaded hole is laterally formed at the center of the connecting slider 86. The surface of the multimeter 2 is provided with a positive electrode test line 3 and a negative electrode test line 4, and the ends of the positive electrode test line 3 and the negative electrode test line 4 are electrically connected to the electrode plates arranged in the inner cavities of the first test head 7 and the second test head 8, respectively. The adjustment groove... The inner cavity is equipped with a driving assembly that drives the first test head 7 and the second test head 8 to slide. The driving assembly drives the first test head and the second test head 8 to move towards or relative to each other. The position of the test head can be conveniently adjusted according to the different diode electrode spacing, so as to realize the rapid and stable connection between the diode and the multimeter 2 (a multimeter is a measuring circuit composed of ammeter, voltmeter and ohmmeter, etc. through a conversion device. It works based on Ohm's law and the series and parallel resistance law. It is mainly composed of mechanical, display and electrical parts. It is divided into digital and pointer types.

The resistance value is calculated by measuring the current of the series circuit and according to Ohm's law. This technology is existing technology and will not be described in detail here) to complete the conductivity test of various diodes quickly and stably.

[0022] The driving component includes an adjusting screw 6 and an adjusting end 9. The adjusting screw 6 is rotatably mounted inside the adjusting groove, and the connecting slider 86 is threadedly connected to both ends of the adjusting screw 6 through threaded holes. The adjusting end 9 is rotatably nested on the surface of the test platform 1 on one side of the adjusting screw 6, and the end of the adjusting end 9 is fixedly connected to one side of the adjusting screw 6. The adjusting screw 6 is a double-threaded screw, and opposite threads are formed on both sides of the surface of the adjusting screw 6. When the adjusting end 9 is rotated, the connecting slider 86 can move stably within the adjusting groove 5 under the drive of the adjusting screw 6, allowing the first test head 7 and the second test head 8 to slide synchronously in opposite or the same direction. The distance between the two test heads can be adjusted accurately and quickly according to different diode electrode spacings, effectively improving the applicability and efficiency of the device for testing the conductivity of diodes of different sizes.

[0023] The sliding seat 81 at the end of the test chamber 84 has a storage groove 82 inside. A protective block 83 is slidably mounted inside the storage groove 82. A threaded connection hole 11 is laterally opened on the back of the storage groove 82. A threaded connection rod 12 is threadedly connected inside the threaded connection hole 11. A rotating connection shaft 10 is fixedly connected to the inner side of the threaded connection rod 12, and the rotating connection shaft 10 is rotatably connected to the back of the protective block 83. A hand-tightening head is fixedly connected to the end of each threaded connection rod 12, and the surface of the hand-tightening head is provided with anti-slip texture. The lower surface of the protective block 83 is attached to the upper surface of the motor plate, and the protective block 83 is adapted to the test chamber. The storage groove 82, protective block 83, and matching threaded connection rod 12 and hand-tightening head structure are set in the sliding seat 81 at the end of the test chamber 84. When the equipment is idle or being moved, the protective block 83 can be easily slid out and closely fit the motor plate by rotating the anti-slip hand-tightening head, which effectively avoids the motor plate from being contaminated by dust and debris and from accidental collision damage, thus extending its service life.

[0024] It should be noted that this utility model is a conductivity testing device for diode production. Depending on the size of the diode being tested, rotating the adjusting end 9 causes the adjusting screw 6 to rotate synchronously. Since the connecting slider 86 is threaded to both ends of the adjusting screw 6 through threaded holes, and the adjusting screw 6 has opposing threads on both sides of its surface, when the adjusting screw 6 rotates, the connecting slider 86 moves within the adjusting groove 5 along the axial direction of the adjusting screw 6. This allows the first test head 7 and the second test head 8 to slide synchronously and stably in opposite or opposing directions, thereby precisely adjusting the distance between the two test heads. To adapt the diode to the electrode spacing of the diode under test, the wires at both ends of the diode are placed into the test chambers 84 of the first test head 7 and the second test head 8, respectively. Under the action of gravity, the wires on both sides of the diode are tightly attached to the electrode plates 85 at the bottom of the test chamber 84, thereby achieving rapid connection between the positive and negative terminals of the diode and the positive and negative terminals of the multimeter 2, and effectively ensuring the stability of the contact. Then, the conductivity of the diode is detected by the positive test line 3 and the negative test line 4 of the multimeter, and the corresponding test data is clearly displayed on the multimeter 2. The structure is simple, easy to operate, reduces the difficulty of testing, and effectively improves the testing efficiency of diodes.
