The principle of operation of the present invention will now be described as follows: the power supply of the controller 16 is connected, each test probe 11 is connected with a computer (the computer can display the test result of each test probe 11 on the corresponding test point in real time through built-in software, and alarm prompt personnel when the test result exceeds a threshold value), a communication module main board to be tested is placed into each placing frame plate 4, the controller 16 is started, the controller 16 controls the two chain transmission assemblies 2 to work once every 16 seconds, the single working time is 2 seconds, and the two chain transmission assemblies 2 can drive each placing frame plate 4 to synchronously and circularly move through each mounting strip 3;
after the controller 16 is started, two electric push rods 6 are controlled to perform timing 2 seconds of output work, and power is supplied to the connecting loops of the electromagnetic switch 21, the low-point conducting rod 124, the high-point conducting rod 125 and the conducting block 122 after 2 seconds, the electric push rods 6 push the insulating mounting plate 7 to drive the plurality of probe mounting seats 8 to move downwards, each probe mounting seat 8 can drive the corresponding test probe 11 to move downwards synchronously, each test probe 11 is contacted with the corresponding welding pin just before the timing work of the electric push rods 6 is finished, at this time, under the blocking action of each welding pin, each test probe 11 stops moving, and at this time, the insulating mounting plate 7 can drive the probe mounting seat 8 to move downwards for a certain distance, at this time, the test probe 11 moves upwards relative to the probe mounting seat 8, when the thickness of the welding pin is proper, the anti-top test probe 11 of the welding pin moves upwards relative to the probe mounting seat 8, therefore, after the test probe 11 drives the conductive block 122 to move upwards through the heat conducting insulating cylinder 10 and the insulating rod 121, the conductive block 122 is separated from the low-point conductive rod 124, and the conductive block 122 is not contacted with the high-point conductive rod 125, so that the corresponding connection loop of the electromagnetic switch 21 and the low-point conductive rod 124, the high-point conductive rod 125 and the conductive block 122 supplies power, if the thickness of the welding pin is too thin, the distance of the welding pin moving upwards against the test probe 11 relative to the probe mounting seat 8 is too small, so that when the controller 16 delays 2 seconds to supply power to the connection loop of the electromagnetic switch 21 and the low-point conductive rod 124, the high-point conductive rod 125 and the conductive block 122, the conductive block 122 is contacted with the low-point conductive rod 124, at this time, the connection loop of the electromagnetic switch 21 and the low-point conductive rod 124 and the conductive block 122 is conducted, so that the moving contact of the electromagnetic switch 21 is magnetically closed, conversely, if the thickness of the welding pin is too thick, at this time, the distance of the welding pin anti-top test probe 11 moving upwards relative to the probe mounting seat 8 is too large, so that the conductive block 122 contacts with the high-point conductive rod 125, at this time, the electromagnetic switch 21 is conducted with the connection loop of the high-point conductive rod 125 and the conductive block 122, so that the moving contact of the electromagnetic switch 21 still can be magnetically closed, the corresponding LED indicator lamp 22 can be lightened after the moving contact of the electromagnetic switch 21 is closed, and after receiving the closing electric signal of the electromagnetic switch 21, the controller 16 can make the buzzer 23 perform a ringing work, and after hearing the buzzer 23, a person can learn that the welding pin at the corresponding position may have the defect of being too thin or too thick through observing the lightened LED indicator lamp 22;
when the phenomenon that the welding pins are too thin or too thick does not occur, the controller 16 controls the electric push rod 6 to be in contact with the corresponding test points after the timing work is finished, at the moment, the communication module can be tested, and when the electric push rod 6 pushes the insulating mounting plate 7 to move downwards, the sliding rods 133 drive the piston plates 132 to move downwards, at the moment, the hollow plates 131 are positioned above the piston plates 132 to increase in space, so that under the action of pressure difference and the action of the air inlet check valve 137 and the air outlet check valve 139, the hollow plates 131 can generate negative pressure suction through the air suction hose 134 to enable the air suction holes 136 of the adsorption plates 135, so that the air around the test probes 11 can be driven to flow, and the air flow can assist the rapid dissipation of heat generated during the electrified test of the test probes 11;
after the electric push rod 6 finishes the output work in 2 seconds, the controller 16 controls the first normally closed electromagnetic valve 155 in each round hole 154 to electrify and work, because the space below the piston plate 132 of the hollow plate 131 is compressed when the piston plate 132 moves downwards, the air below the piston plate 132 is in a high-pressure state, after the first normally closed electromagnetic valve 155 is electrified and opened, the high-pressure air below the piston plate 132 in the hollow plate 131 enters the strip-shaped cavity 151 through the communication hose 156 and fills the inside of each annular elastic air bag 152 through each vent 153, at this time, each annular elastic air bag 152 expands and bulges, so that the insulating rod 121 can be wrapped and fastened, the test probe 11 is ensured to be electrified and work in the test process, and the controller 16 controls the second normally closed electromagnetic valve 158 after the electric push rod 6 finishes the timing work in 12 seconds, at this time, the redundant air in the cavity 151 can be discharged through the air outlet hole 157, and the redundant air can be discharged under the elastic recovery function of the self-elastic air bag, and the insulating rod 121 can not be continuously inflated, and the normally closed electromagnetic valve 16 can be tightly wrapped and tightly controlled by the second electromagnetic valve 16 after the first normally closed electromagnetic valve 16 is electrified, the test probe 11 is tested, the test result can be calculated, the test probe 11 is tested, and the test result can be controlled by the second electromagnetic valve 16, and the test probe 11 and the test machine is tested, and the test machine is tested;
and at the 12 th second after the timing operation of the electric push rods 6 is finished, the controller 16 controls the two electric push rods 6 to perform the return operation of timing 2 seconds, at this time, the insulating mounting plate 7 drives the piston plate 132 to move upwards again through the sliding rod 133, because the second normally closed electromagnetic valve 158 and the first normally closed electromagnetic valve 155 still keep the electrified state at this time, after the piston plate 132 moves upwards and resets, the air pressure of the space below the piston plate 132 in the hollow plate 131 can restore to normal pressure, the air above the piston plate 132 is compressed, and under the action of the air inlet check valve 137 and the air outlet check valve 139, the compressed air enters the air cavity 142 through the bent pipe 145 and the connecting pipe 146, and when the controller 16 controls the electric push rods 6 to perform the return operation, the driving motor 17 is synchronously controlled to perform the timing operation of 5 seconds, the driving motor 17 can drive the rotating plate 18 to rotate, when each air passing hole 19 is communicated with each conical air spraying hole 143 through the annular sealing rubber cushion 20, air entering the air cavity 142 is sprayed out from the conical air spraying holes 143, under the impact of high-speed sprayed air flow, the communication module to be tested above the connecting plate 141 is blown up, when the rotating plate 18 drives each air passing hole 19 and the annular sealing rubber cushion 20 to be staggered with the conical air spraying holes 143, the air entering the air cavity 142 cannot be discharged, at the moment, the communication module falls back into the placing frame plate 4 under the action of self weight, when the air cannot be discharged, the air pressure inside the air cavity 142 is increased, so that the air outlet speed of the conical air spraying holes 143 can be increased when the subsequent air passing holes 19 are communicated with the conical air spraying holes 143, the communication module can be continuously jacked up and fall down under the intermittent blowing action of the conical air spraying holes 143, and the communication module can vibrate, the electronic components which are unstable to mount and the welding pins which are unstable to weld can be separated from the main body of the communication module, so that the electronic components can be conveniently measured in the follow-up test;
after the controller 16 controls the timing of the return operation of the two electric pushers 6 to be finished for 2 seconds, the controller 16 controls the two chain transmission assemblies 2 to be operated for 2 seconds at regular time, at this time, the communication module just tested can be moved to the lower part of the next probe mounting seat 8, the test probes 11 at the position can test the points to be tested at other positions of the communication module, after the timing operation of the chain transmission assemblies 2 is finished, the controller 16 can control the electric pushers 6 to be operated for timing output again, and the operation is repeated until each communication module sequentially passes through the test of each test probe 11 on each probe mounting seat 8.
