Description

Technical Field

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

[0002] Electronic components refer to various elements used in electronic circuits, such as resistors, capacitors, inductors, diodes, transistors, etc. They have independent electrical functions and can be fixed on the PCB by welding or other means, and connected to the circuit on the PCB through wires, pads, etc. to form a complete electronic circuit. After the electronic components are installed on the PCB, they need to pass various tests. The testing process usually includes appearance inspection, functional testing, and corrosion resistance testing. Among them, corrosion resistance testing of electronic components is a test method that simulates a specific corrosion environment. It is used to evaluate the corrosion resistance of electronic components in an environment containing acetate mist, so that electronic components can be suitable for special environments such as coastal areas.

[0003] At present, some electronic components are tested for corrosion resistance. Usually, the PCB board with electronic components installed is placed in a salt spray machine to test the corrosion resistance of electronic components on the surface of the PCB board by simulating a specific corrosion environment. During the test, the staff can take out the PCB board at the specified time and judge the corrosion resistance of the electronic components by observing the state of the PCB board surface. When the staff opens the cover of the salt spray machine, the external environment affects the inside of the salt spray machine. At this time, the environment of the corrosion resistance test operation is destroyed. The staff needs to replace the PCB board and conduct the next batch of tests. When the staff conducts corrosion resistance tests on electronic components for different lengths of time, more time is required. Using the salt spray machine for the first time and testing different batches of PCB boards is a time-consuming process and can easily affect the efficiency of the test operation. In addition, some salt spray machines are equipped with a storage tank for storing salt water. During the test, the salt water in the storage tank is discharged through the atomization device to test the electronic components on the surface of the PCB board. After the test operation is completed, the remaining salt water in the storage tank is prone to precipitation, which affects the results of subsequent test operations. In addition, the position of the atomization device in some salt spray machines is relatively stable. When in use, the salt spray is sprayed from one side of the inside of the salt spray machine. The salt spray diffuses and contacts the surface of the electronic components. Therefore, the test results of some electronic components are easily affected by their location. Summary of the invention

[0004] The object of the present invention is to provide a testing device for electronic components, which can ensure that the electronic components can be more fully contacted with salt spray, and at the same time, preliminarily test the stability of the electronic components installed on the surface of the PCB board. Moreover, this device can also increase the diversity of test results within a certain test time, solving the problems that when some electronic components are subjected to corrosion resistance tests in a salt spray machine, batch testing of electronic components is time-consuming, easily affecting the test efficiency, and the position of the atomization device is relatively stable, and the position of the electronic components is likely to affect the test results.

When the pull plate 2823 moves, the first airbag 2822 is deployed, and the other end of the air supply pipe passes through the bottom of the outer frame 2821 and is connected to the first airbag 2822. The first airbag 2822 is deployed, and under the action of negative pressure, air can be injected into the interior of the first airbag 2822 through the air supply pipe.

[0042] The protection mechanism 32 includes a hollow cylinder 321, a piston plate 322, a polished rod 323, a fixing seat 324 and a T-plate 325. The hollow cylinder 321 is fixed to the surface of the salt spray machine body 1. The surface of the piston plate 322 is slidably connected to the inner wall of the hollow cylinder 321. The polished rod 323 slides through the top of the hollow cylinder 321. The bottom of the polished rod 323 is fixed to the top of the piston plate 322. The fixing seat 324 is fixed to the top of the polished rod 323. The T-plate 325 is hinged to the inside of the fixing seat 324. The surface of the T-plate 325 is connected to the inner wall of the limit frame 33. The top cover 31 is in contact with the wall, and one end of the ventilation pipe 34 is connected to the top of the hollow cylinder 321. When the staff flips over the top cover 31, the T-plate 325 moves inside the limit frame 33, and the T-plate 325 cooperates with the fixing seat 324 to drive the light rod 323 to move. At this time, the piston plate 322 moves accordingly, and the air inside the hollow cylinder 321 can be injected into the second airbag 35 through the ventilation pipe 34. The second airbag 35 expands and cooperates with the first sealing groove 29 and the second sealing groove 30, thereby increasing the sealing performance of the top cover 31 when in use.

[0043] Working principle: The staff first pours salt water into the liquid storage tank and seals the liquid storage tank with the cover plate 8, then the staff can open the top cover 31 and start the servo motor 2811, the adjustment plate 2813 drives the pull plate 2823 to move, the first air bag 2822 is deployed, and the air inside the air storage barrel 261 is discharged. Under the action of the elastic force of the second compression spring 264, the lifting plate 263 drives the lifting rod 262 to lift, and the bottom frame 265 drives the support plate 15 to rise, and the storage plate 18 moves upward. After the staff places the PCB board with electronic components installed in the storage tank 22, The position of the hollow frame 211 is moved so that the card plate 213 can limit the top of the PCB board. After that, the staff can fix the position of the hollow frame 211 by cooperating with the positioning pin 214 and the positioning groove. After the position of the PCB board is limited, the staff starts the servo motor 2811 to perform reverse operation, and the storage plate 18 drives the PCB board to descend to the inside of the salt spray machine body 1. During this process, the first airbag 2822 retracts, and the staff flips the top cover 31. The top cover 31 can seal the top of the salt spray machine body 1, and the second airbag 35 expands and fits with the first sealing groove 29 and the second sealing groove 29. The groove 30 cooperates to increase the sealing effect. The staff starts the driving motor 61 and the atomizing device body 3. The atomizing device body 3 atomizes the salt water and sprinkles it into the interior of the salt spray machine body 1. The driving shaft 62 drives the first bevel gear 64 and the stirring rod 63 to rotate. The stirring rod 63 can reduce the precipitation of the salt water inside the liquid storage tank. The first bevel gear 64 cooperates with the bevel gear ring 10 on one side to drive the inclined rod 9 and the bevel gear ring 10 on the other side to rotate. The bevel gear ring 10 cooperates with the second bevel gear 113 to drive the long rod 111 to rotate, and the blade 112 and the gear plate 12 rotate accordingly. The blade 112 can assist the interior of the salt spray machine body 1 When the salt spray flows, the gear plate 12 cooperates with the spur gear 142 to drive the cam 143 to rotate, and the cam 143 cooperates with the force plate 174 to drive the reset plate 172 to move. The placement plate 18 can drive the PCB to move back and forth during the reciprocating movement of the reset mechanism 17, so that the electronic components on the surface of the PCB can better contact with the salt spray. At the same time, the placement plate 18 drives the vertical plate 20 to move back and forth, and the shape plate 23, the vibration rod 24 and the side plate 25 can generate vibration, which is transmitted to the surface of the PCB, so as to conduct a preliminary test on the stability of the connection of the electronic components on the surface of the PCB;

[0044] During the test, the staff can take out the PCB boards on both sides in batches at regular intervals. When the staff takes one side of the PCB board, the first airbag 2822 expands and cooperates with the support plate 15 to cover one side of the inside of the salt spray machine body 1, and the extension mechanism 19 cooperates with the side plate 25 to drive the storage plate 18 to move, so as to release the contact between the force-bearing plate 174 on one side and the cam 143, so that the support plate 15 can be lifted smoothly. When the first airbag 2822 expands, the lifting rod 262 can drive the base frame 265 to lift, and the support plate 15 drives the storage plate 18 to rise. Finally, the staff can remove one side of the PCB board and observe the corrosion on its surface.
