Technical Field
[0001] This utility model relates to the technical field of rectifier bridge testing equipment, specifically to a rectifier bridge automated line testing switching device. Background Technology
[0002] The primary function of a rectifier bridge is to convert alternating current (AC) to direct current (DC). In power electronic circuits, the rectifier bridge is a crucial component, making performance parameter testing extremely important. Automated rectifier bridge production lines manufacture rectifier bridges of various specifications and models. During production, testing equipment is required to perform performance tests. However, equipping each model with a matching testing device inevitably increases production costs. Therefore, developing a testing device adaptable to different models to achieve rapid testing of rectifier bridges has become a pressing technical challenge. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides an automated testing and switching device for rectifier bridge lines. This device, by incorporating probe supports and a touchscreen, can quickly match different models of rectifier bridges, effectively improving production efficiency and saving production costs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rectifier bridge automated line test switching device, comprising a test platform, an intermediate relay, a touch screen, and a test fixture. The test fixture further comprises a mounting plate, on which a movable plate that can move in the vertical direction is provided. A probe support is fixedly connected to the movable plate. The probe support is provided with a plurality of mounting holes. The probe is inserted into the mounting holes. The probe is electrically connected to the test platform. The test platform is connected to the touch screen through the intermediate relay.
[0005] The probe support is fixedly connected to three connecting shafts, which are bolted to the connecting plate, and the connecting plate is fixedly connected to the movable plate.
[0006] The mounting plate is fixedly mounted with a slide rail, and the movable plate is slidably connected to the slide rail via a slider.
[0007] The testing fixture is also equipped with a lifting mechanism, the extended end of which faces the movable plate and is fixedly connected to the top of the movable plate.
[0008] The lifting mechanism is a pneumatic cylinder or an electric cylinder.
[0009] The beneficial effects of this utility model are as follows: By replacing different probe supports, the probe can be quickly disassembled and installed, and the test route can be switched by clicking the touch screen, thereby matching different models of rectifier bridges, which effectively improves production efficiency and saves production costs.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0015] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example
[0016] like Figure 1 As shown, this utility model provides a rectifier bridge automated line test switching device, including a test platform 1, an intermediate relay 2, a touch screen 3, and a test fixture. The test fixture includes a mounting plate 4, on which a movable plate 5 that can move in the vertical direction is provided. A probe support 6 is fixedly connected to the movable plate 5. The probe support 6 is provided with a plurality of mounting holes 11. The probes 7 are inserted into the mounting holes 11 and are electrically connected to the test platform 1. The test platform 1 is connected to the touch screen 3 through the intermediate relay 2.
[0017] Specifically, the probe support 6 is fixedly connected to three connecting shafts 12, the connecting shafts 12 are bolted to the connecting plate 13, and the connecting plate 13 is fixedly connected to the movable plate 5, which facilitates the quick installation and replacement of the probe support 6.
[0018] Specifically, a slide rail 8 is fixedly installed on the mounting plate 4, and the movable plate 5 is slidably connected to the slide rail 8 through a slider 9 to ensure that the movable plate 5 slides vertically without deviation, thereby ensuring the stability of the rectifier bridge test.
[0019] Specifically, the test fixture is also equipped with a lifting mechanism 10. The extended end of the lifting mechanism faces the movable plate 5 and is fixedly connected to the top of the movable plate 5. The lifting mechanism 10 is a cylinder or an electric cylinder. Using a cylinder or an electric cylinder as a lifting device can achieve rapid response and complete the extension and retraction work in a short time, further improving production efficiency.
[0020] When the rectifier bridge is transferred to the testing section, the lifting device 10 drives the movable plate 5 to descend, thereby making the probe 7 contact the rectifier bridge for testing. Since the touch screen 3 is electrically connected to the testing platform 1 (which uses existing technology) via the intermediate relay 2, different models of probe supports 6 can be replaced for different products, and the test circuit can be switched directly by clicking the touch screen 3, which effectively improves production efficiency and saves labor costs.
[0021] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
