Description

Electronic component performance testing device

Technical Field

The present invention relates to the technical field of electronic component detection, and in particular to an electronic component performance detection device.

Background Art

The testing and screening service of electronic components is also called the secondary screening of electronic components. The secondary screening of electronic components refers to the screening of electronic components by the user or a third party entrusted by the user on the basis of the screening of component manufacturers. The secondary screening is a series of targeted tests based on various failure modes of electronic components, so as to effectively eliminate early failures. In view of the current status of electronic component design, manufacturing and process in my country, as well as many uncontrollable factors in the procurement of imported components, the secondary screening of electronic components has become an indispensable part of stimulating potential design and production defects of electronic components, effectively eliminating early failure products, and improving the reliability of the whole system. The test and screening service projects include visual inspection, high-temperature storage, three-temperature testing (normal temperature, high temperature, low temperature), temperature cycling, leak detection, noise detection (PIND), random vibration, swept frequency vibration, constant acceleration, high temperature aging, high and low temperature operation and DPA (destructive physical analysis).

The existing patent document with announcement number CN220752241U discloses an automatic detection device for the performance of electronic components. By setting up a detection sliding plate, a placement plate and a lighting lamp, when the detection personnel need to detect the electronic components, they can place the electronic components one by one in the card slot and turn on the power of the lighting lamp. The lighting lamp will directly shine light on the bottom of the electronic components, turn on the power of the detection sliding plate, and then the detection sliding plate will detect the electronic components inside the placement plate, thereby improving the work efficiency of the detection personnel in detecting the electronic components; through the setting of the blower and the detection support, when the detection personnel need to clean the dust on the surface of the electronic components, they can turn on the power of the blower, and the air duct will convey the wind to the inside of the detection support, and then the air outlet will convey the wind to the surface of the placement plate so that the wind will clean the dust on the surface of the electronic components, thereby avoiding the situation where the detection personnel manually wipe and cause some electronic components to be damaged by wiping.

Although the above-mentioned automatic electronic component performance detection equipment can solve the corresponding technical problems, it uses wind power to transport dust to the surface of the placement plate so that the wind can clean the dust on the surface of the electronic components. However, the blown dust will float in the surrounding working environment and attach to the electronic components again, causing secondary pollution. At the same time, the size of the card slots on the placement plate is relatively fixed. When testing electronic components of different models, different placement plates need to be prepared for electronic components of different models, resulting in high preparation costs. For this reason, an electronic component performance detection device is proposed.

The front sides of the limit grooves C131, B132 and A341 are all open structures, and the rear sides of the limit grooves C131, B132 and A341 are all closed structures, which can ensure that the dust removal mechanism 5, the detection plate 4 and the clamping mechanism 2 can be pulled out and pulled on the support mechanism 1, and can also prevent the dust removal mechanism 5, the detection plate 4 and the clamping mechanism 2 from being misaligned due to excessive movement when they are placed on the support mechanism 1.

Working principle:

S1. Electronic component clamping operation: First, use the knob 2441 to pull the rectangular frame 21, and the rectangular frame 21 drives the limit strip A211 to slide in the inner cavity of the limit slot A341 until the rectangular frame 21 is almost pulled out from between the two lower side seats 12; then place the electronic component in the rectangular frame 21 and between the two clamping plates 22, and use the knob 2441 to rotate the stud 244. Under the action of the thread, the stud 244 drives the movable plate 245 to move toward the direction of the rectangular frame 21, and the movable plate 245 drives the inclined plate 246 and the inclined plate 246. The groove 247 moves synchronously, and the inner wall of the inclined groove 247 applies pressure to the sliding column 243, so that the sliding column 243 slides in the inner cavity of the inclined groove 247, and the sliding column 243 drives the slider 241 to slide in the inner cavity of the sliding hole 242, and the slider 241 drives the corresponding clamping plate 22 and the rubber pad 23 to slide synchronously in the inner cavity of the rectangular frame 21 until the two rubber pads 23 contact the electronic components, and the two clamping plates 22 can be used to clamp and fix the electronic components; finally, the rectangular frame 21 fixed with the electronic components to be tested is pushed to the original state;

S2. Cleaning of electronic components: First, start the motor B541. The output shaft of the motor B541 drives the screw 542 to rotate. Under the action of the thread, the screw 542 drives the screw sleeve 543 to move horizontally along the axial direction of the screw 542. The screw sleeve 543 drives the shell B531 and the sponge strip 532 to move synchronously. The screw sleeve 543 also stretches or compresses the folding curtain 58 on its side. The sponge strip 532 can sweep the front of the electronic components to be tested on the clamping mechanism 2; then start the exhaust fan 552, so that the dust on the surface of the electronic components and the dust swept by the sponge strip 532 can enter the inner cavity of the shell A51 through the air inlet, the shell B531 and the duct 551 in turn. The dust passes through After filtering, the filter 553 is discharged from the housing A51 by the exhaust fan 552, so that the dust on the front surface of the electronic components and the dust swept by the sponge strip 532 can be uniformly collected and filtered; after cleaning, pull the housing A51 so that the housing A51 drives the limit strip C511 to slide in the inner cavity of the limit groove C131 until the housing A51 is completely pulled out from between the two upper side seats 13, which can provide an important premise for the subsequent detection of the detection board 4; when the filter 553 needs to be cleaned or replaced after long-term use, unscrew the screws between the inspection plate 52 and the housing A51, remove the inspection plate 52, and take out the filter 553 for cleaning or replacement, so as to improve the subsequent filtering effect of the filter 553;

S3. Electronic component inspection operation: First, open the inspection plate 4 and the lighting lamp 8, use the lighting lamp 8 to provide auxiliary lighting for the electronic components to be inspected on the clamping mechanism 2, and use the inspection plate 4 to inspect the front of the electronic components on the clamping mechanism 2; after the front inspection is completed, align the limit bar C511 with the limit slot C131 and slide it in, so that the shell A51 is placed between the two upper side seats 13, and then start the rodless cylinder 61, so that the slide table of the rodless cylinder 61 drives the upper side seat 13, the inspection plate 4 and the dust removal mechanism 5 to move up synchronously, and the upper side seat 13 drives the sliding sleeve 63 to slide on the surface of the guide rod 62 until it moves up to the maximum limit; then start the motor A32, and the motor A32 drives the movable column 33, the rotating bar 34 and the clamping mechanism 2 to rotate slowly and synchronously. The adjusting member 24 is moved so that it rotates one hundred and eighty degrees from top to bottom, thereby driving the electronic components on the clamping mechanism 2 to rotate and turn over one hundred and eighty degrees; then the rodless cylinder 61 is started so that the slide of the rodless cylinder 61 drives the upper side seat 13, the detection plate 4 and the dust removal mechanism 5 to move downward synchronously until the upper side seat 13, the detection plate 4 and the dust removal mechanism 5 move downward to the maximum limit; finally, the dust removal mechanism 5 sweeps and vacuums the back sides of the electronic components on the clamping mechanism 2. After cleaning, the shell A51 is pulled so that the shell A51 drives the limit strip C511 to slide in the inner cavity of the limit groove C131 until the shell A51 is completely pulled out from between the two upper side seats 13, and then the detection plate 4 can detect the back sides of the electronic components on the clamping mechanism 2.

In summary, the electronic component performance detection device comprises a clamping mechanism 2 formed by a rectangular frame 21, a clamping plate 22, a rubber pad 23 and a distance adjusting member 24. The distance adjusting member 24 can drive the two clamping plates 22 to move synchronously toward or away from each other, and then the distance between the two clamping plates 22 can be adjusted according to the size of the electrical components, so that the clamping mechanism 2 can be suitable for electrical components of different models, without the need to prepare a plurality of different clamping mechanisms 2, which helps to reduce the preparation cost; the dust removal mechanism 5 is mainly formed by the shell A51, the inspection plate 52, the dust sweeping member 53, the displacement member 54, the dust collecting member 55 and the partition plate 56. The dust sweeping member 53 is driven by the displacement member 54 to move horizontally on the top of the clamping mechanism 2, and the dust sweeping member 53 can be used to clean the clamping mechanism 2. The electrical components are dusted; through the coordinated use of the dust collecting member 55 and the dust sweeping member 53, the dust on the top of the electrical components and the dust swept down by the dust sweeping member 53 can be absorbed and filtered, thereby effectively preventing the dust from flying into the surrounding working environment and causing secondary adhesion pollution; the lifting mechanism 6 can drive the detection plate 4 and the dust removal mechanism 5 to move upward or downward. When the detection plate 4 and the dust removal mechanism 5 move upward, the turning mechanism 3 can drive the clamping mechanism 2 to rotate and turn over, so that the front and back sides of the electrical components on the clamping mechanism 2 can be inspected, so that there is no need to repeatedly take and place the electrical components on the clamping mechanism 2 during the front and back side inspection process, which helps to improve the inspection efficiency.

Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
