[0036] The following is for reference. Figure 1-5 Describe this utility model;

[0037] The rectifier bridge unit insulation testing device includes:

[0038] A support frame 100, comprising several evenly distributed and detachably fixedly mounted on the edge of a rotating disk, is provided. The rotating disk is driven to rotate by a rotating mechanism, which includes a rotary cylinder or a rotary motor. An insulating pad 110 is fixedly connected to the top of the support frame 100. A conductive seat 120 is fixedly connected to the insulating pad 110. The conductive seat 120 has a detection position adapted to the rectifier bridge 400. The plastic casing of the rectifier bridge is located at the detection position, with four pins extending horizontally, such as... Figure 2-3 As shown, the area below the pin is the insulating pad 110 area;

[0039] The test frame 200 has several units, which are evenly distributed and fixedly set on the worktable and located around the rotating disk. The top of the test frame 200 is provided with a vertically fixed linear drive mechanism 210. The top of the linear drive mechanism 210 is provided with an insulation test platform 220 fixedly connected to the end of the telescopic rod. Below the insulation test platform 220 are electrodes A230 and B240 adapted to the rectifier bridge. Electrodes A230 and B240 are respectively connected to the insulation tester.

[0040] In this case, the linear drive mechanism 210 includes a lifting cylinder, a lifting electric push rod, or a lifting hydraulic cylinder.

[0041] The support frame 100 at station 1 (station 1 marked with a rotating disk in the diagram) uses a material feeding suction cup robotic arm to suck up the rectifier bridge 400 and place it into station 1. The rotating disk rotates counterclockwise, moving the support frame 100 from the adjacent empty station into the material loading area. This process of feeding and rotating is repeated sequentially, forming a structure like... Figure 1 In the aforementioned state, after the rectifier bridges in the designated workstation area are filled, the piston rod of the linear drive mechanism 210 in the test frame 200 retracts, pressing electrode A230 and electrode B240 down to the corresponding required positions of rectifier bridge 400. The conductive copper plate A243 on the top of electrode A230 and the conductive copper plate B242 on the top of electrode B240 are respectively connected to the insulation tester to test the corresponding rectifier bridge 400. The problematic rectifier bridges are marked (the test frame 200 is equipped with a retractable marking pen).

[0042] After the test is completed, the piston rod of the linear drive mechanism 210 rises, and electrodes A230 and B240 separate from the rectifier bridge 400. The rotary disk rotates, and the rectifier bridge is transferred to the next process by the material transfer suction cup robotic arm.

[0055] After the rotating disk rotates to the set position, the piston rod of the linear drive mechanism 210 presses down, and electrode A230 covers the body of the rectifier bridge and contacts the conductive base 120 at the same time; electrode B240 is attached to the pin. After the linear drive mechanism 210 completes its operation, it is tested. If the insulation is insufficient, it will break down. If it is qualified, it passes. After the test is completed, it is picked up by a robotic arm or a suction pen for sorting.
