AI Technical Summary
In existing switching power supply testing methods, when the testing frame is moved back and forth by a hydraulic rod, areas with weak welds may not be able to detach, affecting subsequent use.
A vibration table for testing switching power supplies was designed. The testing frame is moved irregularly by shaking and pulling components. The compression and rebound of springs and foam cotton cause loose welds to fall off. The position of the switching power supply is restricted by a pressing component to prevent it from falling off.
This improves the yield rate of switching power supply testing, ensuring that loosely soldered areas can be removed promptly, making it easier to screen out faulty power switches.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of switching power supply technology, and more specifically to a vibration table for testing switching power supplies. Background Technology
[0002] A switching power supply, also known as a switching converter or switching power supply, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures. The input of a switching power supply is mostly AC power (such as mains power) or DC power, while the output is mostly devices that require DC power, such as personal computers. The switching power supply performs the voltage and current conversion between the two.
[0003] After the switching power supply is manufactured, it needs to be tested to inspect the internal solder joints and prevent incomplete or weak soldering. Currently, the testing process involves placing the power supply inside a testing frame and then moving the frame back and forth using a hydraulic rod, causing the power supply to shake. The power supply is then removed and shaken again. The presence of any sounds from inside the power supply indicates the presence of incomplete or weak soldering. However, the smooth movement of the testing frame using a hydraulic rod can cause some weakly soldered areas to remain attached, potentially affecting the power supply's subsequent use. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a platform, with a swaying assembly at the top of the platform. The swaying assembly includes six support plates fixedly connected to the top of the platform. The six support plates are divided into three groups, and each of the three groups of support plates has a support rod fixedly connected inside. Two connecting plates are slidably connected to the outside of each support rod. A detection frame is fixedly connected to the top of each connecting plate. A first spring is fixedly connected between the outside of one of the connecting plates and the outside of the support plate. Foam is slidably connected between the outside of the other connecting plate and the outside of the support plate. Two foam pieces are provided, one of which is slidably connected between the two connecting plates and the outside of the support rod. Four upright plates are fixedly connected to the outside of the detection frame, divided into two groups. A U-shaped block is rotatably connected inside each of the two groups of upright plates. A limit plate is fixedly connected to the bottom of each upright plate, and the outside of the limit plate is fixedly connected to the outside of the detection frame.
[0006] The present invention is further configured such that: a pulling assembly is provided on the top of the platform, the pulling assembly includes two mounting plates fixedly connected to the top of the platform, a motor is fixedly connected to the outer side of one of the mounting plates, a screw is fixedly connected to the transmission end of the motor, the end of the screw is rotatably connected to the outer side of the second mounting plate, and a transmission frame is threadedly connected to the outer side of the screw.
[0007] The present invention is further configured such that: the pulling assembly includes a transmission rod fixedly connected inside the transmission frame, two pulling blocks are rotatably connected to the outside of the transmission rod, a lifting block is slidably connected to the outside of the pulling block, the bottom of the lifting block is fixedly connected to the top of the platform, and the outside of the pulling block is slidably connected to the inside of the U-shaped block.
[0008] The present invention is further configured such that: a stabilizing component is provided at the bottom of the pulling block, the stabilizing component includes a telescopic rod fixedly connected to the bottom of the pulling block, a limiting plate is fixedly connected to the outside of the telescopic rod, a wheel is fixedly connected to the bottom of the telescopic rod, and a fourth spring is fixedly connected between the top of the wheel and the bottom of the limiting plate.
[0009] The present invention is further configured such that: a pressing component is provided on the top of the detection frame, the pressing component includes a mounting frame fixedly connected to the top of the detection frame, and two L-shaped plates are provided on the outside of the mounting frame, one of the L-shaped plates being fixedly connected to the outside of the mounting frame, and the other L-shaped plate abutting against the outside of the mounting frame.
[0010] The present invention is further configured such that: the pressing assembly further includes a first slide rod that passes through the L-shaped plate and is slidably connected to the L-shaped plate, a pressing plate is fixedly connected to the bottom of the first slide rod, and a second spring is fixedly connected between the top of the pressing plate and the top of the inner cavity of the L-shaped plate.
[0011] The present invention is further configured such that: an adjustment component is provided on the outer side of one of the L-shaped plates, the adjustment component includes a slide cylinder fixedly connected to the outer side of the L-shaped plate, the slide cylinder passes through the mounting frame and is slidably connected, a second slide rod is slidably connected inside the slide cylinder, the end of the second slide rod is fixedly connected to the inside of the mounting frame, and a third spring is fixedly connected between the inside of the mounting frame and the end of the slide cylinder.
[0012] In summary, this utility model has the following beneficial effects:
[0013] 1. This utility model involves pulling a U-shaped block, which moves the upright plate, thereby moving the detection frame and the connecting plate. This compresses the first spring and the foam cotton. Then, the U-shaped block is released momentarily, causing the first spring to cause the connecting plate to spring back, thus restoring the detection frame to its original position. This allows the switching power supply placed inside the detection frame to move synchronously, causing any loosely welded parts inside the switching power supply to detach. This makes it easier to shake the switching power supply and hear a sound, allowing for the screening of faulty power switches and improving the yield rate.
[0014] 2. This utility model compresses the second spring by pulling the pressing plate, then places the switching power supply inside the detection frame, and then releases the pressing plate. At this time, the second spring will drive the pressing plate to press the switching power supply, thereby restricting the position of the switching power supply. Furthermore, by pushing the L-shaped plate, the sliding cylinder can be moved outside the second sliding rod, while simultaneously compressing the third spring. After the switching power supply is placed, the L-shaped plate can be released, and the sliding cylinder can be moved by the third spring, thereby moving the L-shaped plate to the outside of the switching power supply. This further restricts the position of the switching power supply, preventing it from falling off when the detection frame shakes. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] This embodiment discloses a vibration table for testing switching power supplies, such as... Figure 1-5 As shown, the system includes a platform 1. A swaying assembly is installed on the top of the platform 1. The swaying assembly includes six support plates 2 fixedly connected to the top of the platform 1. The six support plates 2 are divided into three groups. Support rods 3 are fixedly connected inside each of the three groups of support plates 2. Two connecting plates 4 are slidably connected to the outside of the support rods 3. A detection frame 7 is fixedly connected to the top of the connecting plate 4. A first spring 5 is fixedly connected between the outside of one of the connecting plates 4 and the outside of the support plate 2. Foam cotton 6 is slidably connected between the outside of the other connecting plate 4 and the outside of the support plate 2. There are two foam cotton 6. One foam cotton 6 is slidably connected between the two connecting plates 4 and the outside of the support rods 3. Four upright plates 8 are fixedly connected to the outside of the detection frame 7. The four upright plates 8 are divided into two groups. U-shaped blocks 9 are rotatably connected inside each of the two groups of upright plates 8. Limiting plates 10 are fixedly connected to the bottom of the upright plates 8. The outside of the limiting plates 10 is fixedly connected to the outside of the detection frame 7.
[0023] By pulling the U-shaped block 9, the upright plate 8 moves, which in turn moves the detection frame 7 and the connecting plate 4, thus compressing the first spring 5 and the foam cotton 6. Then, the U-shaped block 9 is released momentarily. At this moment, the first spring 5 will cause the connecting plate 4 to spring back, which will cause the detection frame 7 to return to its original position. This will cause the switching power supply placed inside the detection frame 7 to move synchronously, thereby causing any loosely soldered parts inside the switching power supply to fall off. This makes it easier to shake the switching power supply and hear a sound, which can then be used to screen out faulty power switches, thereby improving the yield rate.
[0024] The platform 1 is equipped with a pulling assembly at the top. The pulling assembly includes two mounting plates 11 fixedly connected to the top of the platform 1. A motor 12 is fixedly connected to the outside of one of the mounting plates 11. A screw 13 is fixedly connected to the transmission end of the motor 12. The end of the screw 13 is rotatably connected to the outside of the second mounting plate 11. A transmission frame 14 is threadedly connected to the outside of the screw 13.
[0025] The pulling assembly also includes a transmission rod 15 fixedly connected inside the transmission frame 14. Two pulling blocks 16 are rotatably connected to the outside of the transmission rod 15. A lifting block 17 is slidably connected to the outside of the pulling block 16. The bottom of the lifting block 17 is fixedly connected to the top of the platform 1. The outside of the pulling block 16 is slidably connected to the inside of the U-shaped block 9.
[0026] The motor 12 drives the screw 13 to rotate, which in turn drives the transmission frame 14 to move, thereby driving the transmission rod 15 to move, which in turn drives the pulling block 16 to move, thus causing the pulling block 16 to drive the U-shaped block 9 to move. When the pulling block 16 moves to the outside of the lifting block 17, the lifting block 17 will cause the pulling block 16 to rotate along the transmission rod 15, thereby separating the pulling block 16 from the U-shaped block 9, so that the U-shaped block 9 can return to its original position.
[0027] The bottom of the pull block 16 is provided with a stabilizing component, which includes a telescopic rod 18 fixedly connected to the bottom of the pull block 16, a limit plate 19 fixedly connected to the outside of the telescopic rod 18, a wheel 20 fixedly connected to the bottom of the telescopic rod 18, and a fourth spring 21 fixedly connected between the top of the wheel 20 and the bottom of the limit plate 19.
[0028] The telescopic rod 18 is supported by the wheel 20 and the limiting plate 19 is supported by the fourth spring 21, so that the telescopic rod 18 is always in the extended state. When the pulling block 16 is lifted by the lifting block 17, the pulling block 16 will gradually separate from the lifting block 17. At this time, the fourth spring 21 will drive the limiting plate 19 to return to its original position, and will also drive the telescopic rod 18 to return to its original state.
[0029] The top of the detection frame 7 is provided with a pressing component, which includes a mounting frame 22 fixedly connected to the top of the detection frame 7. Two L-shaped plates 23 are provided on the outside of the mounting frame 22. One L-shaped plate 23 is fixedly connected to the outside of the mounting frame 22, and the outside of the other L-shaped plate 23 abuts against the outside of the mounting frame 22.
[0030] The pressing assembly also includes a first slide rod 25 that passes through and is slidably connected to the L-shaped plate 23. A pressing plate 24 is fixedly connected to the bottom of the first slide rod 25, and a second spring 26 is fixedly connected between the top of the pressing plate 24 and the top of the inner cavity of the L-shaped plate 23.
[0031] By pulling the pressure plate 24, the second spring 26 is compressed. Then, the switching power supply is placed inside the detection frame 7. After releasing the pressure plate 24, the second spring 26 will drive the pressure plate 24 to press the switching power supply, thereby restricting the position of the switching power supply.
[0032] One of the L-shaped plates 23 has an adjustment component on its outer side. The adjustment component includes a slide cylinder 27 fixedly connected to the outer side of the L-shaped plate 23. The slide cylinder 27 passes through the mounting frame 22 and is slidably connected. The inside of the slide cylinder 27 is slidably connected to a second slide rod 28. The end of the second slide rod 28 is fixedly connected to the inside of the mounting frame 22. A third spring 29 is fixedly connected between the inside of the mounting frame 22 and the end of the slide cylinder 27.
[0033] By pushing the L-shaped plate 23, the slide cylinder 27 is driven to slide outside the second slide rod 28, while the third spring 29 is compressed. After the power supply is placed, the L-shaped plate 23 can be released, and the slide cylinder 27 is driven to move by the third spring 29, thereby moving the L-shaped plate 23 to the outside of the power supply. This restricts the position of the power supply, so that the power supply will not fall off when the detection frame 7 shakes the power supply.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
