Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to a TVS tube packaging testing device. Background Technology

[0002] A TVS diode is a special diode used to protect electronic equipment from transient overvoltage damage. It is primarily used to limit overvoltages in circuits and guide them to ground, protecting sensitive electronic components such as integrated circuits and voltage regulators. TVS diodes are typically manufactured using alloy anodes, large-diameter structures, and special doping processes. When an overvoltage occurs in a circuit, the TVS diode responds quickly and forms a conductive path, guiding the overvoltage to ground. This protects other electronic equipment from the effects of overvoltages. During the manufacturing process, TVS diodes are usually subjected to current to test their electrical performance and ensure production quality. Existing testing methods typically involve manual sequential inspection, which is inefficient. Therefore, we propose a TVS diode packaging and testing device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a TVS tube packaging and testing device to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A TVS tube packaging inspection device includes a worktable. An end-face bearing is mounted on the top of the worktable, and a disc is fixedly mounted on the top of the end-face bearing. Multiple receiving slots are evenly arranged axially on the top of the disc, with the bottom of each slot completely penetrating the surface. An insulating layer is bonded to the inside of each receiving slot, and limit protrusions are provided inside the slots. A support rod is mounted on one side of the top of the worktable, and a display screen and a buzzer are fixedly mounted on the top of the support rod. The buzzer and the display screen are electrically connected via wires. The top of the worktable is also fixedly equipped with spaced-apart... A fixing block is located on the rear side of the disc. The fixing block is made of insulating material. A round rod is provided on the front top of the fixing block. A first return spring is fixedly installed at the bottom front end of the round rod. A conductor metal sheet is fixedly installed at the bottom end of the first return spring. The conductor metal sheet is electrically connected to the input terminal of the display through a wire. Limiting blocks are provided at intervals on the rear bottom of the disc and mounted on the worktable. A second return spring is fixedly installed on the top of the limiting block. An arc-shaped conductive sheet is fixedly installed on the top of the second return spring. The conductive sheet is electrically connected to the output terminal of the display through a wire.

[0006] By adopting the above technical solution, the TVS tube is inserted into the receiving slot of the disc. By rotating the disc, the two terminals of the TVS tube can be electrically connected to the input and output terminals of the display screen through the conductor metal sheet and the conductive sheet. The TVS tube is tested by the built-in program of the display screen. If it fails, an alarm will be sounded by a buzzer, realizing the rapid batch testing of TVS tubes.

[0007] In a further embodiment, heat-shrinkable insulating tubing is fitted onto the surfaces of both the first and second reset springs. The conductive metal sheet is bonded and fixed to the bottom of the first reset spring, and the first reset spring is used to drive the conductive metal sheet to approach the top surface of the disk. The conductive sheet is bonded and fixed to the top of the second reset spring, and the second reset spring is used to drive the conductive metal sheet to approach the bottom surface of the disk.

[0008] By adopting the above technical solution, the wire diameter of the first reset spring should be smaller than that of the second reset spring in actual use, because the conductor metal sheet has a certain mass and will naturally fall to contact the top pin of the TVS tube.

[0009] In a further embodiment, the periphery of the disk is provided with anti-slip texture, and the top of the workbench is provided with a ground wire connector.

[0010] Since the above technical solution requires manual rotation of the disc during use, there is still a certain risk of electric shock. Therefore, a grounding connector needs to be installed on the workbench to provide leakage protection.

[0011] In a further embodiment, an ambient humidity sticker is fixedly installed on the top of the workbench.

[0012] By adopting the above technical solution, the TVS tube can be avoided from being damaged by electric arc at the moment of contact during the test due to excessively high ambient humidity.

[0013] In a further embodiment, a limiting plate is provided on the top of the workbench.

[0014] By adopting the above technical solution, the limiting plate is preferably made of transparent material. The limiting plate restricts the operator's hand and prevents the operator's hand from entering the rear semicircular area of ​​the disc, thereby further increasing the safety performance.

[0015] In a further embodiment, a lighting source is fixedly installed at one corner of the top of the workbench.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. By inserting the TVS tube into the receiving slot of the disc and rotating the disc, the two terminals of the TVS tube can be electrically connected to the input and output terminals of the display screen through the conductor metal sheet and the conductive sheet. The TVS tube is tested by the built-in program of the display screen. When it fails, an alarm is sounded by a buzzer, realizing the rapid batch testing of TVS tubes. Attached Figure Description
