Description

Technical Field

[0001] The utility model relates to the technical field of switching power supply detection, in particular to a vibration table for switching power supply detection. Background Art

[0002] A switching-mode power supply (SMPS), also known as a switching power supply or switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through various architectures. The input of a switching power supply is typically an AC power source (such as the mains) or a DC power source, while the output is typically for devices requiring DC power, such as personal computers. The switching power supply performs the voltage and current conversion between the two.

[0003] In the prior art, a Chinese utility model patent with publication number "CN217466149U" and patent name "Vibration Table for Switching Power Supply Testing" discloses a vibration table for switching power supply testing. The patent records technical solutions such as "a motor can drive a cam to reciprocate and squeeze a vibration plate, so that the vibration plate drives the switching power supply to vibrate up and down under the action of the elastic restoring force of the spring, thereby automatically vibrating the switching power supply. After the vibration ends, the switching power supply is gently shaken, and then the presence of leaking solder or loosely welded electronic components inside the switching power supply can be determined by listening for collisions with objects inside the switching power supply, thereby reducing labor intensity and improving detection efficiency."

[0004] However, in actual use, this technical solution causes the switching power supply to be placed in the detection area and vibrated by the vibration plate. Since the switching power supply is not restricted and fixed in the detection area, the vibration of the vibration plate may cause the switching power supply to collide with the inner wall of the detection area and be damaged. In severe cases, the switching power supply may fall into other detection areas or the ground after being vibrated out of the detection area, causing damage, thereby affecting the normal detection of the switching power supply.

[0005] Therefore, in order to solve the above technical problems, the utility model proposes a vibration table for switching power supply detection. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 3As shown, a vibration table for switching power supply detection includes a base 1, a vibration detection table 2 and a storage table 6. The four corner ends of the top surface of the base 1 and the four corner ends of the bottom surface of the vibration detection table 2 are fixedly connected with connecting bases 3, and vibration springs 4 are fixedly connected between the upper and lower symmetrical connecting bases 3. The bottom surface of the vibration detection table 2 is also fixedly connected to a vibration motor 5, and the storage table 6 is fixedly connected to the top surface of the vibration detection table 2. The top surface of the storage table 6 is provided with a plurality of storage slots 7. When the vibration motor 5 is turned on, the vibration detection table 2 vibrates through the vibration springs 4 between the connecting bases 3 installed between the opposite walls of the base 1 and the vibration detection table 2, and thereby The storage table 6 on the top surface is driven to vibrate, so that the switching power supply fixed by the fixing mechanism 8 in the built-in slot 7 of the storage table 6 is vibrated. After the vibration is finished, the switching power supply is taken out and gently shaken. By listening to whether there is any object inside the switching power supply and colliding, it is judged whether there is a welding leak inside the switching power supply, or the electronic components are not firmly welded. When the inspection personnel hear a collision sound inside the switching power supply, it means that there is a welding leak inside the switching power supply or the electronic components are not firmly welded, and the switching power supply is an unqualified product. If there is no sound inside the switching power supply, it is a qualified product, so as to achieve the purpose of completing the inspection of the switching power supply by the vibration table;

[0022] A fixing mechanism 8 is respectively provided on the front and rear sides of the storage table 6, and the fixing mechanism 8 includes a concave plate 10, a screw 14, a movable plate 17, a push rod 21 and a push plate 22. The concave plates 10 are respectively fixedly installed on the front and rear side walls of the storage table 6, and the screw 14 is movably connected to the inside of the concave plate 10 through the rotating rod 15 at the outer end. The movable plate 17 is movably connected to the concave plate 10 through the sliders 18 on both sides, and the movable plate 17 is also movably connected to the screw 14 through the nut 20 in the front end wall. Several push rods 21 corresponding to the storage slots 7 are fixedly connected to the rear wall of the movable plate 17, and the push plate 22 is fixedly connected to the rear end of the push rod 21.

[0023] like Figure 2 As shown, a plurality of through holes 9 are respectively provided on the front and rear side walls of the storage platform 6 and are interconnected with the storage groove 7. The through holes 9 provided on the storage platform 6 are used to cooperate with the use of the push rod 21, ensuring that the push rod 21 can enter the storage groove 7 through the through holes 9;

[0024] like Figure 2 As shown, concave plates 10 are fixedly installed on the front and rear side walls of the storage platform 6, and sliding openings 11 are respectively opened on the left and right side walls of the concave plate 10. A mounting hole 12 is opened on the front end wall of the concave plate 10, and a bearing 13 is fixedly installed in the mounting hole 12. The sliding openings 11 opened on both sides of the concave plate 10 are used to cooperate with the slider 18 to realize the sliding operation, and the bearings 13 installed in the mounting holes 12 are used to cooperate with the rotating rod 15 to realize the rotation operation;

[0025] like Figure 3 As shown, a rotating rod 15 is fixedly installed at the front end of the screw 14, and the rotating rod 15 is fixedly installed with the bearing 13. A knob 16 is fixedly installed at the front end of the rotating rod 15. When the switching power supply is placed in the storage slot 7 for testing, the knob 16 is rotated to drive the rotating rod 15 to rotate in the bearing 13, and the rotating rod 15 will drive the screw 14 to rotate;

[0026] like Figure 3 As shown, sliders 18 are fixedly installed on the left and right side walls of the movable plate 17, and the sliders 18 are movably installed in the sliding opening 11. A fixing hole 19 is opened on the front end wall of the movable plate 17, and a nut 20 is fixedly installed in the hole of the fixing hole 19. The nut 20 is threadedly connected with the screw rod 14. When the screw rod 14 rotates, the movable plate 17 will move inward along the screw rod 14 through the nut 20 installed in the fixing hole 19, and the slider 18 slides in the sliding opening 11.

[0027] like Figure 3 As shown, a plurality of push rods 21 are fixedly installed on the rear end wall of the push rod 21, and the push rods 21 are correspondingly inserted and installed in the through holes 9. The rear end of the push rod 21 is also fixedly installed with a push plate 22 located in the storage groove 7. Driven by the movement of the movable plate 17, the push rod 21 will pass through the through hole 9 into the storage groove 7, and push the switching power supply in the storage groove 7 through the push plate 22 until the switching power supply is tightly fixed in the storage groove 7, thereby avoiding the problem of collision and vibration falling damage of the switching power supply in the storage groove 7 when the switching power supply is subjected to vibration detection.

[0028] It should be noted that the present invention is a vibration table for testing switching power supplies. After placing the switching power supply to be tested in the corresponding storage slot 7 opened on the top surface of the storage table 6 installed on the top surface of the vibration testing table 2, the knob 16 on the outer wall of the concave plate 10 installed on the front and rear sides of the storage table 6 is rotated. The knob 16 will drive the rotating rod 15 to rotate in the bearing 13 installed in the mounting hole 12, and the rotating rod 15 will drive the screw 14 to rotate. During the rotation of the screw 14, the nut 20 installed in the fixing hole 19 opened at the front end of the movable plate 17 will move inward along the screw 14, and the nut 20 will drive the movable plate 17 to move synchronously. When moving, the sliders 18 installed on both sides of the movable plate 17 will slide in the sliding openings 11 opened on both sides of the concave plate 10, and the push rod 21 installed at the rear end of the movable plate 17 will pass through the corresponding through holes 9 opened on the front and rear sides of the storage platform 6 and enter the storage slot 7. At the same time, the push plate 22 installed at the rear end of the push rod 21 will push the switch power supply of the storage slot 7 and fix the switch power supply tightly in the storage slot 7 until the knob 16 can no longer be rotated. Then, the vibration motor 5 installed on the bottom surface of the vibration detection table 2 is turned on to make the vibration detection table 2 pass through the base 1 and the vibration detection table. 2 The vibration spring 4 between the connecting base 3 installed between the opposite walls vibrates, and thereby drives the storage table 6 on the top surface to vibrate, so that the switching power supply fixed by the fixing mechanism 8 in the built-in slot 7 of the storage table 6 vibrates. Finally, after the vibration ends, take out the switching power supply and gently shake it. By listening to whether there is any object inside the switching power supply to judge whether there is a welding leak or loose soldering of electronic components inside the switching power supply, when the inspection personnel hear the sound of collision inside the switching power supply, it means that there is a welding leak or loose soldering of electronic components inside the switching power supply, and the switching power supply is If the switching power supply does not make any sound, it is a qualified product. The purpose of testing the switching power supply is achieved by using a vibration table. The switching power supply is tightly fixed in the storage slot 7 by the fixing mechanism 8 for testing. During the vibration test, the switching power supply can effectively avoid colliding with the inner wall of the storage slot and being damaged by falling from the storage slot to the ground, thereby ensuring that the switching power supply can be tested normally. After the vibration ends, the knob 16 is rotated in the opposite direction so that the push plate 22 no longer presses against the switching power supply and the switching power supply can be taken out of the storage slot 7.
