Description

Technical Field

[0001] This utility model relates to the field of diode testing technology, specifically a lifting device for a diode testing platform. Background Technology

[0002] The diode testing platform is mainly used to evaluate the electrical performance parameters and reliability of diodes, ensuring their stability in harsh environments. By measuring key parameters such as forward voltage drop and reverse current, it can quickly determine whether the electrical performance of the diode meets the standards. It can simulate extreme environments such as high temperature, high humidity, and temperature cycling to test the diode's anti-aging ability and sealing performance under long-term operation, analyze failure modes under surge current impact, predict equipment failure risks, and reduce the probability of system downtime due to component failure.

[0003] However, traditional diode detection has the following drawbacks:

[0004] Traditional diode testing requires manually placing the diode directly under the testing equipment and waiting for the equipment to rise and fall automatically before the test can be completed. The excessively long descent time of the testing equipment significantly reduces the efficiency of diode testing. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for a diode testing platform, in order to solve the problem mentioned in the background art that in traditional diode testing, the diode needs to be manually placed directly below the testing equipment and then wait for the testing equipment to rise and fall automatically before the testing can be completed. The time it takes for the testing equipment to fall automatically is too long, which greatly reduces the efficiency of diode testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a diode testing platform, comprising a support body, a lifting component fixedly installed at one end of the inner wall of the support body, support components fixedly installed on both sides of the bottom end of the inner wall of the support body, a height rod fixedly installed inside the support body, a height shell slidably connected to the top of the height rod, an adjustment component fixedly installed in the middle of the height shell, and a placement component fixedly installed at the top of one side of the support body. The lifting component includes a cylinder fixing plate and a lifting cylinder, the top of the cylinder fixing plate being fixedly connected to the fixed end of the lifting cylinder, and a lifting platform fixedly installed at the movable end of the lifting cylinder.

[0007] Preferably, the cylinder fixing plate is provided with positioning platforms on both sides, and lifting rods that are slidably connected to the lifting platform are fixedly installed on both sides of the top of the two positioning platforms. Sealing sleeves are provided at the connection points of the four lifting rods and the lifting platform. One side of the cylinder fixing plate and one side of the two positioning platforms are fixedly connected to the bracket body. The lifting cylinder performs telescopic movement and pushes the lifting platform from the bottom. The lifting platform slides relative to the lifting rods, which improves the stability of the lifting platform. During the lifting process, the height of the diode placed on it is adjusted.

[0008] Preferably, the adjustment assembly includes two limiting plates and a rotating shaft. One end of each of the two limiting plates on opposite sides is rotatably connected to both ends of the rotating shaft.

The drive gear and the driven gear mesh with each other. Position sensors are fixedly installed on the surfaces of both limiting plates. The bottom end of the other limiting plate is fixedly connected to the height housing. When the servo motor is powered on, it starts and drives the drive gear to rotate. The drive gear contacts the driven gear, and the driven gear drives the rotating shaft to rotate. The rotating shaft drives the drive pulley to rotate, and the drive pulley drives the driven pulley to rotate through the connecting belt. In this way, the diode placed on the top of the lifting platform is adjusted in position after frictional contact.

[0009] Preferably, both of the support components include a first support steel and a second support steel. Both sides of the top of the first support steel are fixedly installed with length steel. The tops of the two length steels are respectively fixedly connected to both sides of the bottom of the second support steel. The top of the second support steel is in contact with the lifting component. Both ends of the first support steel are fixedly connected to the bracket body. The support components provide support from the bottom of the lifting platform and limit the lowest point of the lifting component's movement.

[0010] Preferably, the storage assembly includes a mounting plate and a storage sheet metal. The top of one side of the mounting plate is fixedly connected to one end of the storage sheet metal. A storage groove is formed in the middle of the top of the storage sheet metal. Storage shells are fixedly installed on both sides of the top of the storage sheet metal. The side of the mounting plate away from the storage sheet metal is fixedly connected to the bracket body. A reinforcing plate is fixedly installed at the connection between the mounting plate and the bracket body. The diodes to be tested can be stored in the storage groove in an orderly manner, and the diodes that pass the test and those that fail can be stored in the two storage shells respectively.

[0011] Preferably, the bracket body includes two first side plates and a connecting rod.

[0012] Preferably, mounting bases are fixedly installed at the four corners of the bottom of the bracket body, and vibration damping feet are fixedly installed at the bottom of the four mounting bases. The installation of vibration damping feet reduces the vibration and impact during the operation of mechanical equipment, extends the service life of the equipment, and improves the processing accuracy.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting up a lifting component, the lifting cylinder pushes the lifting platform from the bottom, and the height of the diode placed on it is adjusted during the lifting process of the lifting platform, which replaces the traditional detection equipment that descends on its own to detect the diode, thus improving the detection efficiency of the diode.
