[0036] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0037] like Figure 1-Figure 8 As shown, the present embodiment provides an intelligent ripple test power supply, including a hollow box 1, the shape of the hollow box 1 is stepped, a carrier plate 2 is slidably provided at one end of the top of the hollow box 1 away from the protrusion, a positioning component 3 for fixing the electrical components is provided on the top of the carrier plate 2, a through opening 4 is opened at the top of the hollow box 1 above the protrusion, a shielding mechanism 5 is provided below the through opening 4, a test component 9 is rotatably installed at one end of the interior of the hollow box 1 near the through opening 4, a bracket 6 is installed at the top of the hollow box 1 above the through opening 4, a test module 7 is installed on the top of the bracket 6, the test module 7 includes a power supply and an oscilloscope, a probe 8 is connected to the test module 7, one end of the probe 8 is connected to the oscilloscope, and the probe 8 is inserted into the interior of the hollow box 1 and connected to the test component 9.

[0038] Overall working principle: During the test, the electrical component is first placed on the top of the carrier 2, and its position is corrected using the positioning assembly 3 to ensure that when the carrier 2 moves to a position close to the top of the hollow box 1 and is located at the raised position, the test point of the electrical component can correspond to the joint on the test assembly 9. In the initial state, the through port 4 is in a blocked state. When the movement of the carrier 2 is controlled, the blocking state of the through port 4 is automatically released, and then the test assembly 9 extends from the through port 4. When the carrier 2 reaches the maximum moving distance, the test assembly 9 is automatically connected to the electrical component, and a ripple test is performed through the test module 7.

[0039] In this embodiment, the shielding mechanism 5 includes a baffle 19, a sliding rod 20 and a return spring 21. The baffle 19 is attached to the inner top of the hollow box 1, and the baffle 19 covers the bottom of the through opening 4. The two ends of the baffle 19 close to the carrier plate 2 are fixed with sliding rods 20. The sliding rod 20 penetrates the hollow box 1 and is fixedly connected to the carrier plate 2. A return spring 21 is provided between the carrier plate 2 and the outer side of the protrusion on the top of the hollow box 1, and the sliding rod 20 passes through the inside of the return spring 21.

[0040] Local working principle: during the movement of the carrier plate 2, the sliding rod 20 pushes the shield 19 to misalign the shield 19 with the opening 4, thereby releasing the blocking state of the opening 4. During the movement of the carrier plate 2, the elastic force on the reset spring 21 needs to be offset first, and during the movement of the carrier plate 2, the carrier plate 2 will compress the reset spring 21 so that it can be reset after the test is completed.

[0041] In this embodiment, the positioning assembly 3 includes an electric telescopic rod 10, a cross bar 11, a vertical rod 12, an L-shaped clamping plate 13, a torsion spring 14, a sheath 15, a lower through slot 16, an upper through slot 17 and a positioning strip 18. The electric telescopic rod 10 is installed on both sides of the hollow box 1. A cross bar 11 is installed between the output ends of the two sets of electric telescopic rods 10. The cross bar 11 is parallel to the width direction of the hollow box 1. Both ends of the top of the cross bar 11 are rotatably installed with vertical rods 12, and the bottom ends of the vertical rods 12 are installed with torsion springs. 14, the vertical rod 12 passes through the inside of the torsion spring 14, and the top end of the torsion spring 14 is fixedly connected to the vertical rod 12, the bottom end of the torsion spring 14 is fixedly connected to the cross bar 11, a sheath 15 is provided on the outside of the torsion spring 14, lower through grooves 16 cooperating with the vertical rod 12 are provided on both sides of the top of the hollow box 1, upper through grooves 17 cooperating with the vertical rod 12 are provided on both sides of the top of the carrier plate 2, an L-shaped clamping plate 13 is fixed to the top of the vertical rod 12, and a positioning strip 18 is fixed to one end of the top of the carrier plate 2 near the through opening 4.

[0042] Partial working principle: After the electrical component is placed on the top of the carrier plate 2, the electric telescopic rod 10 will control the movement of the cross bar 11, and the vertical rod 12 on the cross bar 11 will first slide inside the lower through slot 16 and the upper through slot 17. When the L-shaped clamping plate 13 is not in contact with the electrical component, the carrier plate 2 will not be subjected to tension. When the inner end of the L-shaped clamping plate 13 is in contact with the electrical component, the carrier plate 2 will be subjected to a corresponding force, but the return spring 21 will exert a reaction force on the movement of the carrier plate 2. Therefore, when the force on the carrier plate 2 is less than the elastic force of the return spring 21, the carrier plate 2 will not move, and one end of the L-shaped clamping plate 13 is in contact with the end of the electrical component. After fitting, the electrical component is pushed toward the positioning bar 18 and fits against the side of the positioning bar 18. At the same time, due to the reverse force on the L-shaped clamping plate 13, the rotation of the vertical rod 12 is controlled. The two groups of vertical rods 12 rotate toward each other, and the outer end of the L-shaped clamping plate 13 contacts the side of the electrical component to correct the position of the electrical component. After the position of the electrical component is corrected, the position of the electrical component is fixed, and the two ends of the L-shaped clamping plate 13 contact the side and end of the electrical component respectively. The pulling force applied by the electric telescopic rod 10 will all act on the carrier plate 2. At this time, as the electric telescopic rod 10 is pulled, the stable movement of the carrier plate 2 will be controlled.

[0043] In this embodiment, a roller is rotatably mounted on one end of the L-shaped clamping plate 13 close to the center of the carrier plate 2, and the roller is perpendicular to the horizontal plane.

[0044] Local working principle: When the L-shaped clamp 13 contacts the electrical component, the roller contacts the electrical component first. As the thrust on the electrical component increases, the L-shaped clamp 13 rotates. The setting of the roller can reduce the damage caused by the end of the L-shaped clamp 13 to the electrical component.

[0045] In this embodiment, the test assembly 9 includes a mounting plate 22, pins 23, a positive electrode ring 24, a ground ring 25 and a wire 26. The mounting plate 22 is located below the through opening 4 and parallel to the inner top of the hollow box 1. A rotating assembly is provided at the end of the mounting plate 22. Pins 23 are slidably provided on both sides of the top of the mounting plate 22. The positive electrode ring 24 is sleeved on the front end of the probe 8, and the ground ring 25 is sleeved on the outside of the probe 8. Wires 26 are respectively provided between the positive electrode ring 24, the ground ring 25 and the two groups of pins 23.

[0046] Local working principle: During the test, one group of pins 23 is connected to the test point of the electrical component, and another group of pins 23 is grounded, and the test module 7 is used to observe the ripple.

[0047] In this embodiment, the top of the mounting plate 22 is symmetrically provided with slide grooves 27 along the width direction, and sliders 28 are slidably installed inside the slide grooves 27 , and the pins 23 are respectively fixed on the tops of the sliders 28 .

[0048] Local working principle: Since the test points of different electrical components are located at different positions, it is necessary to control the slider 28 to move inside the slide slot 27 to change the position of the pin 23.

[0049] In this embodiment, a screw rod 29 is rotatably installed between both ends of the slide groove 27, and the ends of the screw rod 29 extend to the outside of the mounting plate 22. The screw rod 29 is threadedly connected to the slider 28, and an adjustment block 30 is fixed to one end of the screw rod 29 located outside the mounting plate 22.

[0050] Partial working principle: When adjusting the position of the pin 23 , the rotating adjustment block 30 drives the screw rod 29 to rotate, and the rotation of the screw rod 29 drives the slider 28 to adjust, thereby changing the position of the pin 23 .

[0051] In this embodiment, the rotating assembly includes a rotating rod 31, an incomplete gear 32, an L-shaped slide plate 33, a tooth block 34 and a strip groove 35. The rotating rod 31 is rotatably installed between the two sides of the hollow box 1. The mounting plate 22 is fixed on the rotating rod 31. An incomplete gear 32 is installed at the middle position of the rotating rod 31. An L-shaped slide plate 33 is slidingly arranged inside the hollow box 1 along the length direction. A tooth block 34 meshing with the incomplete gear 32 is provided at the middle position of the bottom of the L-shaped slide plate 33. The top of the L-shaped slide plate 33 is fixedly connected to the carrier plate 2. A strip groove 35 cooperating with the L-shaped slide plate 33 is opened on the top of the hollow box 1.

[0052] Local working principle: During the movement of the carrier board 2, the L-shaped slide plate 33 will be driven to move. Before the shield plate 19 is completely misaligned with the through-port 4, the end of the L-shaped slide plate 33 is always in contact with the bottom of the mounting plate 22 to ensure the stability of the mounting plate 22. When the through-port 4 is completely unblocked, the tooth block 34 on the L-shaped slide plate 33 is engaged with the incomplete gear 32 to control the incomplete gear 32 to rotate counterclockwise. The mounting plate 22 rotates ninety degrees and is perpendicular to the horizontal plane. At this time, the pin 23 is aligned with the test point. After the mounting plate 22 is vertical, the position of the mounting plate 22 does not change as the L-shaped slide plate 33 moves again. Then the carrier board 2 and the electrical components on the top move one end distance again, and the pin 23 is automatically connected with the test point.

[0053] In this embodiment, the end of the bottom of the L-shaped slide plate 33 close to the corner is in the same horizontal plane as the top of the tooth block 34 , and the end of the bottom of the L-shaped slide plate 33 away from the corner is in contact with the bottom of the mounting plate 22 .

[0054] Partial working principle: the incomplete gear 32 is no longer meshed with the tooth block 34 , and the arc surface on the incomplete gear 32 fits against one end of the bottom of the L-shaped slide plate 33 near the corner, ensuring the stability of the mounting plate 22 .

[0055] like Figure 1-Figure 8As shown, this embodiment provides a test method for an intelligent ripple test power supply as follows:

[0056] Step 1: Place the electrical component on the top of the carrier plate, then start the electric telescopic rod to control the horizontal rod to move inside the hollow box toward the opening, and then control the vertical rod to move inside the upper through slot. The inner end of the L-shaped clamping plate first contacts the end of the electrical component. The L-shaped clamping plate drives the vertical rod to rotate under the resistance of the electrical component. The two ends of the L-shaped clamping plate squeeze the side and end surface of the electrical component respectively to correct the position of the electrical component.

[0057] Steps: The continuous activation of the electric telescopic rod will drive the carrier plate and the electrical components to move toward the opening at the same time. The movement of the carrier plate will compress the return spring and slide the shield plate across the bottom of the opening, thereby releasing the shielding state of the opening.

[0058] Steps: After the shield has completely slid through the bottom of the through-port, the through-port is in an open state. At this time, the tooth block on the L-shaped slide plate will mesh with the incomplete gear. The mounting plate is controlled to rotate counterclockwise. The mounting plate rotates to 90 degrees. The pin is parallel to the horizontal plane. At this time, the incomplete gear is no longer meshed with the tooth block. The arc surface on the incomplete gear fits on the end of the bottom of the L-shaped slide plate near the corner. The rotation angle of the mounting plate is fixed. At this time, the pin is not plugged into the test point;

[0059] Steps: Rotate the adjusting block to rotate the screw rod, and adjust the position of the pin according to the position of the connector on the electrical component to ensure that the pin is aligned with the connector;

[0060] Steps: As the carrier board is moved again, the pin pairs are plugged into the inside of the connector, and the electrical component ripple can be tested through the test module.

[0061] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
