[0005] To solve the above technical problems, this utility model provides the following technical solution: a rectifier bridge power-on testing and marking device, comprising a test platform, a microcontroller, and a placement rack. The test platform has a microcontroller and an audible and visual alarm at its top. The placement rack is mounted on the top of the test platform, and a placement slot is provided inside the placement rack. A square rectifier bridge body is placed on top of the placement rack, and pins are provided below the square rectifier bridge body. Slide rails are provided on the inner walls of both sides of the placement rack, and a mounting frame is provided above the slide rails. Fittings adapted to the slide rails are installed at the top and bottom of the mounting frame. The positioning block has a positioning mechanism inside for limiting the position of the mounting frame. The top and bottom of the mounting frame have sliding grooves, and a test head that penetrates the mounting frame is installed inside the sliding grooves. A conductive plate that contacts the pins is installed on one side of the test head. A buffer mechanism is installed inside the test head. A multimeter is installed on the top of the test platform. The output terminal of the multimeter is electrically connected to the input terminal of the microcontroller through a wire. The output terminal of the microcontroller is electrically connected to the input terminals of the audible and visual alarm and the laser marking head, respectively, through wires.

The moving groove is provided inside the positioning block, and a protrusion is provided inside the moving groove that penetrates the empty groove on one side of the placement frame.

[0007] As a preferred embodiment of the rectifier bridge power-on test marking device of this utility model, a guide rod that penetrates the moving groove is installed inside the protrusion, and a spring that contacts the inner wall of the moving groove is sleeved on the outer wall of the guide rod.

[0008] As a preferred embodiment of the rectifier bridge power-on test marking device of this utility model, the buffer mechanism includes an arc-shaped elastic plate, a slider is provided inside the slide groove, and arc-shaped elastic plates that contact the inner wall of the mounting frame are installed on both sides of the test head, and the arc-shaped elastic plate is U-shaped.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, as Figures 1-5 As shown, this utility model provides a technical solution: a rectifier bridge power-on test marking device, including a test platform 1, a microcontroller 2, and a placement rack 4. The microcontroller 2 and an audible and visual alarm 3 are installed at the top of the test platform 1. The placement rack 4 is installed at the top of the test platform 1, and a placement slot 5 is opened inside the placement rack 4. A square rectifier bridge body 7 is placed on top of the placement rack 4, and pins 21 are arranged below the square rectifier bridge body 7. Slide rails 14 are provided on the inner walls of both sides of the placement rack 4, and a mounting frame 8 is provided above the slide rails 14. Positioning blocks 15 adapted to the slide rails 14 are installed at the top and bottom of the mounting frame 8, and a positioning mechanism for limiting the position of the mounting frame 8 is provided inside the positioning block 15. The positioning mechanism includes a moving slot. The positioning block 15 has a movable groove 16 inside, and a protrusion 17 is provided inside the movable groove 16, which passes through the empty groove on one side of the placement frame 4. A guide rod 18 is installed inside the protrusion 17, which passes through the movable groove 16. A spring 19 is sleeved on the outer wall of the guide rod 18, which contacts the inner wall of the movable groove 16. By pressing the protrusion 17, the guide rod 18 passes through the position of the positioning block 15, causing the spring 19 to contract. The protrusion 17 moves and separates from the empty groove position of the slide rail 14. Then, it pushes the mounting frame 8 to move in the slide rail 14, thereby moving the conductive sheet 11 to the appropriate position of the pin 21. This structure can adjust the position between the conductive sheet 11 and the pin 21, which can meet the requirements of energizing the pins 21 with different spacing.

[0023] Example 2, as Figures 1-6As shown, this utility model provides a technical solution: a rectifier bridge power-on test marking device, including a mounting frame 8 with grooves 9 at the top and bottom, and a test head 10 penetrating the mounting frame 8 inside the grooves 9. A conductive sheet 11 in contact with a pin 21 is installed on one side of the test head 10. A buffer mechanism is provided inside the test head 10, including an arc-shaped elastic plate 13. A slider 12 is provided inside the grooves 9. Arc-shaped elastic plates 13 in contact with the inner wall of the mounting frame 8 are installed on both sides of the test head 10. The arc-shaped elastic plates 13 are U-shaped and located at the four corners of the mounting frame 8. They contact the pin 21 through the conductive sheet 11. To ensure that the conductive sheet 11 and the pin 21 are tightly fitted, the test head 10 drives the conductive sheet 11 to press the arc-shaped elastic plate 13 to one side, causing the arc-shaped elastic plate 13 to tighten, thereby meeting the tight fit requirement and enabling power-on measurement.

[0024] Example 3, as Figures 1-7 As shown, this utility model provides a technical solution: a rectifier bridge power-on test and marking device, including a test platform 1 with a test multimeter 6 installed on the top, a conductive plate 11 in contact with pin 21 installed on one side of the test meter head 10, the output terminal of the test multimeter 6 being electrically connected to the input terminal of the microcontroller 2 via a wire, and the output terminal of the microcontroller 2 being electrically connected to the input terminals of the audible and visual alarm 3 and the laser marking head 20 via wires respectively. The operator can insert the square rectifier bridge body 7, along with the pin 21, into the placement slot 5 in the placement frame 4, thereby pressing the conductive plate 11 through the pin 21, causing the conductive plate 11 to conduct electricity. The information is fed back to the test multimeter 6 through the position of the test meter head 10, and then fed back to the microcontroller 2 through the position of the test multimeter 6. The microcontroller 2 then activates the audible and visual alarm 3 and the laser marking head 20. The operator can determine whether the power-on is qualified through the audible and visual alarm 3, and perform marking through the position of the laser marking head 20.

[0025] Working principle: First, connect the external power supply. The operator can insert the square rectifier bridge body 7 and the pin 21 into the placement frame 4. The pin 21 then presses against the conductive sheet 11, causing the test head 10 to drive the slider 12 to compress the arc-shaped elastic plate 13. Then, under the elastic force of the arc-shaped elastic plate 13, the conductive sheet 11 is tightly attached to the pin 21, meeting the power supply requirements. The conductive sheet 11 then conducts electricity, which is fed back to the test multimeter 6 through the test head 10. The test multimeter 6 then feeds back the information to the microcontroller 2, and the microcontroller 2 activates the audible and visual alarm 3 and the laser marking head 20. The operator can know whether the power supply is qualified through the audible and visual alarm 3 and perform marking through the laser marking head 20.

[0026] When the square rectifier bridge body 7 with different pin spacing 21 is adjusted, the guide rod 18 can be driven through the positioning block 15 by pressing the protrusion 17, so that the spring 19 is tightened, the protrusion 17 moves and separates from the slot of the slide rail 14, and then pushes the mounting frame 8 to move in the slide rail 14, thereby moving the conductive sheet 11 to the appropriate position of the pin 21. This structure can adjust the position between the conductive sheet 11 and the pin 21, and can meet the requirements of energizing the pins 21 with different spacing.

[0027] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
