Description

Technical Field

[0001] The invention relates to the technical field of pressure testing, and in particular to a pressure resistance testing device for electronic components. Background Art

[0002] Compression testing can evaluate the load-bearing capacity of electronic components under specific pressure or voltage, which helps designers and manufacturers understand the extreme performance of components, so as to optimize the design process and improve the overall performance and reliability of products. A magnetic ring is a ring-shaped magnetic conductor, which is usually a commonly used anti-interference component in electronic circuits. The main function of a magnetic ring is to suppress high-frequency noise. In electronic equipment and circuits, high-frequency noise will interfere with signal transmission and the normal operation of equipment. The interior of a magnetic ring is mainly composed of a magnetic ring made of magnetic material and a conductive coil wound on the magnetic ring, and the interior is usually a closed circuit.

[0003] During the compression test on the magnetic ring, the magnetic ring is usually placed vertically on the pressure testing machine, and then the upper pressure component is lowered to contact the magnetic ring and continuously apply pressure to perform the compression test on the magnetic ring. However, the compression test is usually performed at normal temperature or room temperature. Since the magnetic ring also generates heat when working, which is higher than the room temperature, the internal components of the magnetic ring will be deformed and the compression performance will also change. Therefore, the compression test is performed without heating the magnetic ring, and the test results are limited. At the same time, during the compression test, the periphery of the tested magnetic ring lacks protection, and the fragments generated by the crushed magnetic ring are easy to splash, posing a safety hazard.

[0024] 2. In the process of the magnetic ring being compressed and deformed, the present invention drives the long connecting rod to descend through the upper pressure plate, so that the long connecting rod instantly contacts the vertical column and pushes it to descend, so that the first vertical slot, the through hole and the second vertical slot descend and change their positions, so that the third connecting pipe and the U-shaped pipe are in an open-circuit state, and the air supply is stopped, so that the gas inside the horizontal cylinder is discharged after passing through the fourth connecting pipe and the first vertical slot, so as to avoid the residual gas hindering the reset of the second piston, and the second piston and the second movable rod can be reset under the action of the second spring, so as to keep the cylindrical magnet away from the magnetic ring, and prevent the situation that the cylindrical magnet is crushed together with the magnetic ring after the upper pressure plate presses the magnetic ring, thereby implementing the protection of the device's own components.

[0025] 3. In the process of the vertical plate and the horizontal plate approaching the lower seat and the magnetic ring to be measured, the present invention drives the rubber block to move by contacting the push rod, so that the rubber block is closely attached to the surface of the magnetic ring to be measured, thereby clamping and fixing the magnetic ring.

At this time, the connecting cover 2210 and the U-shaped tube 224 are in a closed state.

[0048] When the magnetic ring is placed on the top of the lower seat 7, the sleeve 231 is moved up and down to slide along the surface of the long column 24 until the height of the top of the vertical column 226 is slightly lower than the height of the top of the magnetic ring, and the knob bolt 233 is tightened to position the sleeve 231; when the first solenoid valve 12 and the second solenoid valve 14 are opened to supply gas to the pipe 15, the cover body 19 rises, and then when the gas pushes the first piston 21 to the top of the cylinder 17, the inlet end of the first connecting pipe 221 contacts the bottom of the first piston 21, and then the gas enters the first connecting pipe 221.

The inner wall of the moving sleeve 256 is slidably connected to a transverse column 258. The transverse column 258 is bolted to the inner wall of the shell 1 in a transverse direction. The connecting plate 255 and the moving sleeve 256 are bolted to each other. One end of the connecting pipe 2212 away from the vertical cylinder 225 is connected to the horizontal cylinder 251, connecting the vertical cylinder 225 and the horizontal cylinder 251 together, and the other side of the surface of the horizontal cylinder 251 is connected with a fourth connecting pipe 254, the top of the movable seat 257 is also bolted with a vertical plate 2510, and the top of the vertical plate 2510 is bolted with a horizontal plate 2511. The fourth connecting pipe 254 connects the two groups of horizontal cylinders 251 together, and the surface of the horizontal column 258 is also sleeved with a second spring 259, one end of the second spring 259 is in contact with the surface of the movable sleeve 256, and the second spring 259 is a compression spring, which gives the movable sleeve 256 a force away from the lower seat 7, so that the movable seat 257 is initially away from the lower seat 7.

[0050] The gyromagnetic mechanism 26 includes a pneumatic motor 261 and a vertical rotating rod 262. The pneumatic motor 261 is bolted to the surface of the vertical plate 2510. The bottom end of the vertical rotating rod 262 is fixed to the output shaft of the pneumatic motor 261. The top of the horizontal plate 2511 is fixed with a horizontal rotating rod 263 through a bearing seat, which enables the horizontal rotating rod 263 to rotate. The top of the vertical rotating rod 262 penetrates to the top of the horizontal plate 2511 and is connected to the horizontal rotating rod 263 through a bevel gear transmission. The vertical rotating rod 262 is rotatably connected to the penetration point of the horizontal plate 2511. One end of the vertical rotating rod 262 is bolted with a cylindrical magnet 264. The end of the fourth connecting pipe 254 away from the horizontal cylinder 251 is connected to the inlet end of the pneumatic motor 261. The pneumatic motor 261 adopts an adjustable speed model. After the magnetic ring is placed on the lower seat 7 and the gas is supplied, the cover body 19 rises, and then the gas passes through the first connecting pipe 221, the hose 222, the third connecting pipe 2212, etc., and enters the interior of the horizontal cylinder 251. The high-pressure gas pushes the second piston 252 to move, and the second piston 252 drives the second movable rod 253 to move, so that the second movable rod 253 drives the connecting plate 255, the movable sleeve 256 and the movable seat 257 to move together, so that the movable seat 257 drives the vertical plate 2510, the horizontal plate 2511, the horizontal rod 263 and the cylindrical magnet 264 to move together, drives the second spring 259 to be in a compressed state, and allows the cylindrical magnet 264 to enter the center of the magnetic ring, and the lower seat 7 The surface of the lower seat 7 is also penetrated by a push rod 27, one end of which is fixed with a rubber block 28. The push rod 27 is slidably connected to the penetration of the lower seat 7. When the vertical plate 2510 approaches the lower seat 7, it will contact the push rod 27 and push the push rod 27 and the rubber block 28 to approach the magnetic ring. When the cylindrical magnet 264 passes through the inside of the magnetic ring, the rubber block 28 clings to the surface of the magnetic ring to fix it. At this time, the second piston 252 is located at one end of the inside of the transverse cylinder 251 close to the entrance of the fourth connecting pipe 254, which makes the entrance of the fourth connecting pipe 254 and the side of the inside of the transverse cylinder 251 away from the lower seat 7 communicate with each other. The high-pressure gas is continuously transported and enters the inside of the pneumatic motor 261 through the fourth connecting pipe 254, and then passes through the The air is discharged through the outlet end of the pneumatic motor 261, which causes the output shaft of the pneumatic motor 261 to start rotating, which drives the vertical rotation rod 262 to rotate, and drives the horizontal rotation rod 263 to rotate through the bevel gear, thereby driving the cylindrical magnet 264 to rotate on the middle side of the magnetic ring, constantly changing the magnetic field, causing the closed coil inside the magnetic ring to generate current. The coil inside the magnetic ring itself is usually a closed circuit. The magnetic ring inductor coil is mainly composed of a magnetic ring made of magnetic material and a conductive coil wound on the magnetic ring. When the magnet passes through the closed coil and rotates, since the magnetic field of the magnet is constantly changing with its rotation, the magnetic flux passing through the coil will also change accordingly. The magnetic flux is a physical quantity that describes the "amount" of magnetic field passing through a certain area.When the magnet rotates, its magnetic field direction, intensity or both may change, resulting in a change in the magnetic flux passing through the coil. According to Faraday's law of electromagnetic induction, when the magnetic flux changes, an induced electromotive force will be generated in the closed circuit. If the circuit is closed and the resistance in the circuit is not zero, this induced electromotive force will generate an induced current in the circuit. Therefore, the cylindrical magnet 264 rotates on the middle side of the magnetic ring, which will generate current inside the magnetic ring being detected, and gradually increase the temperature of the magnetic ring, thereby heating the magnetic ring from the inside, avoiding the use of a heat source to heat the detected component, causing the pressing component to deform due to heating; in order to cooperate with the test, a temperature sensor can be installed on the surface or periphery of the lower seat 7 to monitor the temperature of the magnetic ring, and the speed of the pneumatic motor 261 can be adjusted to adjust the rotation speed of the cylindrical magnet 264 to achieve temperature regulation. Then, the hydraulic system of the driving device is driven to allow the upper pressure plate 4 to descend to press down on the detected magnetic ring for detection, thereby simulating the pressure resistance of the magnetic ring when it is higher than normal temperature, thereby expanding the scope of application of the device.

[0051] When the magnetic ring is initially pressed, the long connecting rod 2213 is only close to the top of the vertical column 226, with a small gap in the middle. At the moment when the magnetic ring is pressed and deformed to the point of damage, the upper pressure plate 4 can drive the long connecting rod 2213 and the circular ring 2214 to descend together, and contact with the vertical column 226 to push it down. The vertical column 226 descends to compress the first spring 2211, and at the same time, the first vertical groove 227, the through hole 228 and the second vertical groove 229 on the surface of the vertical column 226 descend together. The lower half of the first vertical groove 227 enters the interior of the vertical cylinder 225, and the upper half of the first vertical groove 227 is still outside the vertical cylinder 225, so that the end of the third connecting pipe 2212 close to the vertical cylinder 225 is connected with the first vertical groove 227, and the through hole 228 is no longer aligned with the upper end of the U-shaped tube 224 and the third connecting pipe 2212. At this time, the lower end of the U-shaped tube 224 is aligned with the second vertical groove 229 and the connecting cover 2210, and the subsequent gas passes through the U-shaped tube 224, the second vertical groove 229 and the connecting cover 2210. The gas is discharged from the groove 229 and the connecting cover 2210, and the gas is no longer supplied through the third connecting pipe 2212. The gas inside the horizontal cylinder 251 can also be discharged after passing through the third connecting pipe 2212, the vertical cylinder 225, and the first vertical groove 227. The first vertical groove 227 will not allow the upper end of the U-shaped tube 224 to be the same as the third connecting pipe 2212. At this time, the gas supply to the horizontal cylinder 251 is stopped, and the internal gas can also be discharged. Under the action of the second spring 259, the movable sleeve 256 is brought The movable seat 257, the connecting plate 255, the vertical plate 2510, the horizontal plate 2511, the horizontal rotation rod 263 and the cylindrical magnet 264 are away from the lower seat 7 and the magnetic ring to prevent the cylindrical magnet 264 from being crushed by the upper pressure plate 4 after the magnetic ring is crushed, so that the cylindrical magnet 264 can automatically hide after the magnetic ring is crushed. At the same time, the cover body 19 is also around the lower seat 7 to prevent the fragments of the magnetic ring from flying around after the shattering. Deep grooves 29 are opened on both sides of the cover body 19 to cooperate with the long connecting rod 2213 or the horizontal rotation rod 263 to enter.

[0052] After the detection is completed, the first solenoid valve 12 is closed to stop the air supply, and the third solenoid valve 16 is opened. At this time, the first piston 21 lacks air pressure and drops, and the cover body 19 drops under the action of weight. The gas inside the cylinder body 17 is discharged after passing through the pipe 15 and the discharge pipe 13, and the remaining gas inside the first connecting pipe 221, the hose 222 and the second connecting pipe 223 is discharged through the port below the U-shaped tube 224, the second vertical groove 229 and the connecting cover 2210. Most of the remaining gas inside the fourth connecting pipe 254 is discharged through the pneumatic motor 261, and a small amount of gas will be temporarily drawn into the inside of the horizontal cylinder 251 due to the reset of the second piston 252; after the cover body 19 drops, the upper pressure plate 4 rises, and the vertical column 226 is reset under the action of the first spring 2211, and then the magnetic ring fragments that fall into the inner side of the cover body 19 and are on the surface of the fixed platform 6 and the lower seat 7 are taken out.
