Description

Technical Field

[0001] The present invention relates to the technical field of inductance detection, and in particular to a product performance detection device and a detection method for producing an integrally formed inductor. Background Art

[0002] After the inductor is produced, it needs to be tested to ensure that it meets production requirements.

[0003] When the inductor is tested, the power module starts to supply power, the controller turns on the timer, the LC oscillation circuit generates a phase signal, and the voltage generated by the LC oscillation circuit and the voltage generated by the reference voltage circuit are both sent to the comparison circuit for voltage value comparison, and the output value of the comparison circuit is sent to the controller. When the comparison value received by the controller is a high level, the timer in the controller keeps timing, otherwise the timer stops timing. The controller records the timing time of the timer as ts, and calculates the inductance L' of the inductor L1 to be tested according to the formula L'=Rt, where R represents the resistance value of the resistor R1; calculates the inductance L" of the inductor L1 to be tested according to the formula, where f represents the frequency of the phase signal generated by the LC oscillation circuit, and C represents the capacitance value of the capacitor C1; compares the measurement results: the controller calculates |L"-L'|, if |L"-L'|≤ε, the test passes, assuming the actual inductance of the inductor L1 to be tested is L, if |L"-L'|>ε, the controller drives the display circuit and the alarm circuit, the display circuit displays the measurement result, and the alarm circuit issues an alarm message. The above detection technology is the existing technology.

[0004] However, the disadvantage of this existing technology is that it requires manual labor to place and remove the inductors, which is inconvenient and increases the workload of the staff.

The bottom of the airbag 23 is fixedly connected to an air intake pipe 21, and an air intake one-way valve 22 is installed on the air intake pipe 21, which can remove dust from the one-piece molded inductor.

[0035] A feeding plate 8 is slidably connected to the base 1, and a first rack plate 9 is embedded in the upper end of the feeding plate 8. A transmission mechanism that drives the first rack plate 9 is installed on the base 1.

[0037] The present invention also discloses a method for detecting a product performance detection device for producing an integrally formed inductor, comprising the following steps:

[0038] S1, first place the integrally formed inductor in the material frame 10 and stack them, then start the electric telescopic rod 13;

[0039] S2, the electric telescopic rod 13 works to drive the cross plate 17 and the electric detection head 19 to move downward, and at the same time drives the second rack plate 35 to move downward. The downward movement of the second rack plate 35 drives the second gear 34, the second transmission wheel 33, the belt 29, the first transmission wheel 31, and the first gear 32 to rotate, thereby driving the first rack plate 9 and the feed plate 8 to move;

[0040] S3, the feed plate 8 moves to drive the integrally formed inductor to move, and at the same time drives the baffle 25 to move. The baffle 25 first blocks the discharge trough 7, and then the feed plate 8 pushes the integrally formed inductor into the discharge trough 7;

[0041] S4, the electric telescopic rod 13 drives the horizontal plate 17 to continue to move downward. At this time, the second rack plate 35 is not engaged with the second gear 34, and the electric detection head 19 offsets the integrally formed inductor to realize the power-on detection of the inductor; if it is qualified, the alarm 14 does not work, and if it is unqualified, the alarm 14 works to remind the staff to remove the unqualified parts.

[0042] When the present invention is used, firstly, the integrally formed inductor is placed in the material frame 10 and stacked, and then the electric telescopic rod 13 is started;

[0043] The electric telescopic rod 13 drives the cross plate 17 and the electric detection head 19 to move downward, and at the same time drives the second rack plate 35 to move downward. The second rack plate 35 moves downward to drive the second gear 34, the second transmission wheel 33, the belt 29, the first transmission wheel 31, and the first gear 32 to rotate, thereby driving the first rack plate 9 and the feeding plate 8 to move. The feeding plate 8 moves to drive the one-piece inductor to move, and at the same time drives the cross bar 28 and the baffle 25 to move. The baffle 25 first blocks the inner wall of the discharge trough 7. As the output end of the electric telescopic rod 13 continues to move downward, the cross bar 28 moves to squeeze the spring 27, and the feeding plate 8 pushes the one-piece inductor into the discharge trough 7.

[0044] At the same time, the horizontal plate 17 moves downward to squeeze the airbag 23 downward. The airbag 23 is compressed and the air inside it is discharged through the U-shaped tube 20 and blown onto the inductor located in the discharge trough 7, thereby achieving dust removal for the inductor.

[0045] The electric telescopic rod 13 drives the horizontal plate 17 to continue to move downward. At this time, the second rack plate 35 is no longer engaged with the second gear 34. The electric detection head 19 and the integrally formed inductor are offset to realize the power-on detection of the inductor. If the test result is qualified, the alarm 14 does not work. If the test result is unqualified, the alarm 14 works to remind the staff to remove the unqualified parts.

[0046] After the detection is completed, the output end of the electric telescopic rod 13 moves upward, so that the feeding plate 8 and the baffle 25 are reset. The baffle 25 no longer blocks the discharge chute 7. Under the gravity of the inductor, the inductor is separated from the discharge chute 7. A receiving box can be set under the base 1 to collect the fallen inductor, that is, to realize automatic material collection;

[0047] The inductor in the material frame 10 moves downward under gravity and counteracts the base 1 . When the electric telescopic rod 13 moves downward again, the inductor can be transported and detected again.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
