Description

Technical Field

[0001] The present invention relates to the technical field of inductance testing, and particularly to an inductive load testing device and a testing system based on data analysis. Background Art

[0002] As a key basic device in electronic circuits, inductive components play an irreplaceable role in fields such as power electronics, communication systems, and consumer electronics. The main performance parameters of inductors include inductance, quality factor, DC resistance, and self-resonant frequency, etc. These parameters directly affect the stability, energy efficiency, and signal quality of the circuit. During the production and manufacturing process of inductive components, performance testing is a key link to ensure product quality. Traditional inductance testing methods mainly include the AC bridge method, resonance method, voltage-current method, etc. These methods are based on different measurement principles and can effectively detect various parameters of the inductor. With the development of electronic components towards high frequency and miniaturization, higher requirements are put forward for inductance testing technology, and testing equipment is required to have higher measurement accuracy, faster testing speed, and stronger automation capabilities.

[0003] In recent years, packaging machines based on digital signal processing can achieve multi-parameter synchronous measurement and improve measurement accuracy through algorithm optimization. Through technologies such as mechanical transmission, automatic positioning, and intelligent control, the testing efficiency has been significantly improved. The measurement and transmission speed of digital signals is relatively fast and can meet the requirements of high-efficiency testing. However, when testing inductive components, their pin parts need to be inserted into different test sockets for power connection to complete the test. The insertion of the pins often needs to be straight up and down to avoid deformation and damage of the pins. Therefore, the turntable of the packaging machine needs to stop rotating temporarily, and the testing efficiency is greatly limited by the conveying speed of the inductive components. Summary of the Invention

[0004] The purpose of the present invention is to provide an inductive load testing device and a testing system based on data analysis to achieve the purpose of not damaging the pins of inductive components and realizing high-efficiency testing, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An inductive load testing device based on data analysis includes a packaging machine base, a testing disk, a feeding chute, and a discharging chute. The testing disk is a fixed disk, and six test sockets are arranged annularly on its surface. The test sockets include an inductance value test socket, a quality factor test socket, a DC resistance test socket, a self-resonant frequency test socket, an impedance characteristic test socket, and a saturation current test socket;

[0006] A rotary lifting mechanism is provided at the center of the testing disk, including a lifting table rotatably installed and a suction disk installed thereon for lifting. Eight air suction heads are circumferentially arranged on the suction disk, and each air suction head realizes negative pressure adsorption and positive pressure release through air pressure control;

[0007] The test socket is provided with a front stop seat, a rear stop seat and two pin blocks for dynamically limiting the entry and exit of the inductance element. Each test socket is equipped with an associated seat. Inside the associated seat, the front stop seat, the rear stop seat and the pin blocks in the test socket are controlled to move through the linkage of a floating plate and an associated rope. The pin block forms a mechanical linkage with the push rod of the rear stop seat through an inclined wire groove.

[0008] When the device is running, the suction disc rotates continuously in a wavy trajectory, and the dynamic plug and unplug test of the inductance element is realized through the interaction control between the air suction head and the associated seat.

[0009] Preferably, the motion mode of the rotary lifting mechanism is to alternate between full cycle and half cycle operation;

[0010] The full cycle completes the transfer of the inductance element between adjacent test sockets, and the half cycle triggers the floating plate in the associated seat to press down to switch the test state.

[0011] Preferably, the front stop seat and the rear stop seat are reversely linked through a gear and rack mechanism;

[0012] The gear and rack mechanism includes a first rack fixed to the bottom of the rear stop seat, a second rack fixed to the bottom of the front stop seat, and a wheel shaft rotatably installed in the test socket, with a first gear and a second gear installed at both ends respectively.

[0013] Preferably, the first gear meshes with the first rack, the second gear meshes with the second rack, and the first rack and the second rack are installed in opposite directions.

[0014] Preferably, the pin block is slidably installed through a guide rod, and a return spring for normally separating the pin block is provided on the guide rod. The inclination angle of the inclined wire groove is 30 degrees to 45 degrees.

[0015] Preferably, an electromagnetic seat is provided at the bottom of the associated seat for adsorbing the floating plate in the pressed state to maintain the test duration;

[0016] A cleaning mechanism is integrated in the associated seat, including a screw rod threadedly connected to the floating plate, and a brush installed at the top of the screw rod. The length of the bristles of the brush covers the end face of the air suction head.

[0017] Preferably, a limit rail is provided in the test socket, and the rear stop seat is slidably matched with the limit rail through a slider, and the slider is connected to the floating plate through an associated rope.

[0018] Preferably, the front stop seat and the rear stop seat alternately lift and work. When the rear stop seat is in the low position, the front stop seat is in the high position, allowing the inductance element to enter from the direction of the rear stop seat; during the test, the rear stop seat rises and the front stop seat descends, for the inductance element to move out from the direction of the front stop seat after the test is completed.

[0019] Preferably, both sides of the test plate are respectively connected to the feeding chute and the discharging chute, and the feeding chute and the discharging chute are respectively connected to the feeding seat and the discharging seat on the test plate. The test seat is located between the feeding seat and the discharging seat, and the feeding seat and the discharging seat are set to an intermittent feeding and discharging mode.

[0020] A test system of an inductive load test device based on data analysis, the system includes:

[0021] A multi-parameter synchronous test module, which integrates an LCR digital bridge and is integrated on the test seat for contacting the pins of the inductive element for electrical testing;

[0022] An intelligent motion control module, which uses a servo motor to drive a lifting table and realizes wavy plugging and unplugging through a motion trajectory planning algorithm;

[0023] An adaptive test interface module, which is arranged at the bottom of the test seat, can perform electrical connection of the pins of the inductive element, and monitors the pin deformation through an optical sensor;

[0024] A data analysis and decision-making module, which has a real-time test data processing architecture for analyzing the data collected by the multi-parameter synchronous test module;

[0025] A packaging sorting linkage system, which can automatically grade and mark defective products based on the test results.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The inductive load test device of the present invention has the ability of continuous and efficient testing. Through the design of the rotary lifting mechanism and the wavy motion trajectory, continuous conveying, plugging and unplugging of the inductive element during the test process are realized, changing the working mode that the traditional testing and packaging machine must stop rotating for plugging and unplugging. The unique full-cycle and half-cycle alternating operation mode enables the test state switching and component transfer to be completed synchronously, greatly improving the test efficiency.

[0028] 2. The two-way stop seat mechanism based on the gear-rack linkage cooperates with the pin clamping block driven by the inclined wire groove to form a positioning system. The alternating lifting working mode of the front stop seat and the rear stop seat, combined with the pin clamping block that can be separated and combined, not only ensures the reliable contact of the pins during testing, but also effectively avoids the problem of pin deformation.

[0029] 3. Through the cleaning mechanism integrated in the companion seat, the air suction head is automatically cleaned and maintained in each test cycle, ensuring the long-term stable working performance of the air suction head and significantly extending the continuous operation time of the equipment.

[0030] 4. The continuous and automatic testing of multiple key parameters of the inductive component is achieved through the layout of a dedicated test socket with a circular distribution. A special wavy motion trajectory is adopted to enable the inductive component to be inserted into the test socket in the fastest direction. Through the cooperative design of the electromagnetic socket and the floating plate, a stable holding force is provided for the testing process. Description of the Drawings

Specific Embodiments

[0043] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be combined arbitrarily to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0044] Please refer to Figures 1 to 11 , the present invention provides a technical solution: an inductive load test device based on data analysis. The main structure of the device is a measuring and packaging machine, which can complete the inductance value test, quality factor test, DC resistance test, self-resonant frequency test, impedance characteristic test, saturation current test of inductive components, and perform the packaging work of inductive components after the test is completed.

[0045] As Figures 1 - 3 shown, the device includes a measuring and packaging machine base 1. A test plate 2 is fixedly installed on the working surface of the measuring and packaging machine base 1. Feeding grooves 3 and discharging grooves 4 are respectively connected to both sides of the test plate 2. The feeding grooves 3 and discharging grooves 4 are respectively connected to a feeding seat 5 and a discharging seat 6 on the test plate 2. The inductive components in the feeding groove 3 can be pushed into the feeding seat 5 for transportation and testing, and the inductive components that enter the discharging seat 6 can fall into the discharging groove 4 to enter the packaging process. The test plate 2 is of a disc structure, and a plurality of test seats 7 are annularly arranged thereon. The test seats 7 are located between the feeding seat 5 and the discharging seat 6. Therefore, during normal testing, the feeding seat 5 and the discharging seat 6 are set to an intermittent feeding and discharging mode to ensure that each inductive component can rotate and be transported completely in a circle on the test plate 2 to complete all the testing work. The test seats 7 are successively set as an inductance value test seat, a quality factor test seat, a DC resistance test seat, a self-resonant frequency test seat, an impedance characteristic test seat, and a saturation current test seat, which can perform corresponding testing work after the inductance is connected and powered on.

[0046] As Figure 4As shown, the test disk 2 is a fixed structure. A lifting table 8 is rotatably installed in the middle of the test disk 2, and a suction disk 9 is installed on the lifting table 8. Therefore, the suction disk 9 can be lifted during rotation. Eight air suction heads 10 are annularly arranged on the suction disk 9. The air suction heads 10 are connected to a pneumatic control device. Each air suction head 10 can generate negative pressure or positive pressure. When negative pressure is generated, the inductive components can be grasped. When positive pressure is generated, air is exhausted outward. When the eight air suction heads 10 rotate, they respectively correspond to the feeding seat 5, the discharging seat 6 and the test seat 7 at the bottom, and can transport the inductive components. The traditional testing and packaging machine has a straight up and down transportation method. The turntable structure needs to stop rotating to insert the pins of the inductive components. However, the suction disk 9 of the present invention adopts a non-stop rotating structure, keeps rotating while lifting, and the movement trajectories of the air suction heads 10 and the adsorbed inductive components are wavy, and can obliquely enter the test seat 7.

[0047] As Figures 5 - 7 shown, a front stop seat 11 and a rear stop seat 12 are installed on both sides of the test seat 7 with one rising and one falling, and two pin clamping blocks 14 are symmetrically arranged in the middle. The inductive components are limited by the front stop seat 11 or the rear stop seat 12 in cooperation with the pin clamping blocks 14. Usually, only one of the front stop seat 11 and the rear stop seat 12 is in the raised state to support the inductive components from the side, and the two pin clamping blocks 14 are in a discrete state with a gap therebetween to ensure that the pins of the inductive components can enter from the side. When the two pin clamping blocks 14 converge, the pins of the inductive components can be fixed to carry out stable inductive testing work.

[0048] As Figure 7 、 Figure 8 shown, a companion seat 16 is arranged on one side of each test seat 7. The states of the two stop seats and the pin clamping blocks 14 in the test seat 7 are controlled through the companion seat 16. A rubber ring 17 is arranged at the top of the companion seat 16, and a floating plate 18 is installed in the middle in a lifting and moving manner. Spring steel balls 22 are arranged on the side wall of the floating plate 18. The floating plate 18 can be fixed to the top of the companion seat 16 through the spring steel balls 22 and the connection inside the companion seat 16. A limiting rail 20 is arranged in the test seat 7, and the rear stop seat 12 is connected to the limiting rail 20 through a slider 21. A connecting rope 19 is connected to the slider 21, and the connecting rope 19 passes through the test seat 7 and the companion seat 16 and is connected to the floating plate 18. Therefore, the states of the floating plate 18 and the rear stop seat 12 are interrelated. When the floating plate 18 is at the top, the rear stop seat 12 is at a low position. When the floating plate 18 moves downward in the companion seat 16, the slider 21 can be pulled through the connecting rope 19, so that the rear stop seat 12 moves upward to limit the inductive components from the side.

[0049] As Figure 8As shown, the floating plate 18 of the present invention moves downward by the positive pressure generated by the air suction head 10. The associated seat 16 is located at the middle position between the two test seats 7. If the air suction head 10 rotates from the previous test seat 7 to the next test seat 7 as one cycle, and rotates from the test seat 7 to the associated seat 16 as half a cycle, the suction disc 9 of the present invention rotates and lifts in an alternating manner of one cycle and half a cycle. After the air suction head 10 transfers an inductive component from the front test seat 7 to the rear test seat 7, it moves half a cycle into the associated seat 16. At this time, the air suction head 10 generates positive pressure, causing the floating plate 18 to move downward against the resistance of the spring steel ball 22, thereby driving the rear retaining seat 12 to move upward, and the test seat 7 associated with the associated seat 16 enters the test state. The two pin blocks 14 can tightly limit the pins of the inductive component. And an electromagnetic seat 23 is provided at the bottom of the associated seat 16, which can generate a magnetic force acting on the floating plate 18 for short-time adsorption of the floating plate 18 to control the test time. After the air suction head 10 enters the test seat 7, an elastic member is connected to the floating plate 18, which can move upward and reset. During the reset process, the two pin blocks 14 are separated, and the air suction head 10 can extract the inductive component and transfer it again. In this state, both the front retaining seat 11 and the rear retaining seat 12 are in the middle and do not restrict the inductive component.

[0050] As Figure 9 shown, the front retaining seat 11 and the rear retaining seat 12 can alternately lift and lower. When the rear retaining seat 12 is at the low position, the front retaining seat 11 is at the high position. At this time, the inductive component and its pins can enter the test seat 7 from the direction of the rear retaining seat 12, and the front retaining seat 11 generates a limiting effect. During the test, the rear retaining seat 12 rises and the front retaining seat 11 descends to facilitate the removal of the inductive component from the direction of the front retaining seat 11 after the test is completed. A first rack 24 is fixedly connected to the bottom of the rear retaining seat 12, and a second rack 25 is fixedly connected to the bottom of the front retaining seat 11. A wheel shaft 26 is rotatably installed in the test seat 7, and a first gear 27 and a second gear 28 are respectively connected to both sides of the wheel shaft 26. Among them, the first gear 27 meshes with the first rack 24, the second gear 28 meshes with the second rack 25, and the first rack 24 and the second rack 25 are installed in opposite directions. Therefore, when the rear retaining seat 12 rises, the front retaining seat 11 can move downward, and vice versa.

[0051] As Figure 10 、 Figure 11As shown, the pin clamping blocks 14 are slidably mounted in the test socket 7 through the guide rods 13, and a return spring 15 is arranged on the guide rods 13, and its elastic force can keep the two pin clamping blocks 14 in a separated state to facilitate the entry and exit of the pins of the inductive element. At the same time, a bevel groove 29 is arranged on the pin clamping blocks 14, and a push rod 30 is mounted on the rear retaining seat 12. The push rod 30 is connected in the bevel groove 29. When the rear retaining seat 12 moves up and down, the two pin clamping blocks 14 can be synchronously controlled by the thrust generated by the push rod 30. When the rear retaining seat 12 moves downward, the two pin clamping blocks 14 can converge to limit the pins of the inductive element, and cooperate with the rear retaining seat 12 to ensure the stability of the inductive element during testing.

[0052] As Figure 8 shown, further, a cleaning structure is also provided for the air suction head 10 in the companion seat 16. A screw 31 is rotatably mounted in the companion seat 16. A nut 32 is arranged in the middle of the floating plate 18 and is connected to the screw 31. A brush 33 is assembled at the top of the screw 31. When the air suction head 10 generates positive pressure to press down the floating plate 18, the nut 32 can make the screw 31 rotate, and then make the brush 33 rotate. The end of the air suction head 10 is cleaned by the rotation of the brush 33 to ensure that it can smoothly suck and fix the inductive element after entering the test socket 7.

[0053] The test system of the present invention is constructed based on the above inductive load test device to realize the functions of automatic testing and data analysis. The system architecture includes the following core modules:

[0054] Multi-parameter synchronous test module: Integrate an LCR digital bridge, adopt the four-wire Kelvin test method to eliminate contact resistance, and the test frequency range is 20Hz - 10MHz.

[0055] The multi-parameter synchronous test module is integrated on the test socket 7, and its measurement parameters and accuracy are as follows:

[0056] Inductance (L) measurement range: 0.01μH - 100H, quality factor (Q) measurement accuracy: ±0.5%; DC resistance (DCR) resolution: 1mΩ; self-resonant frequency (SRF) detection bandwidth: 50MHz.

[0057] Further, the multi-parameter synchronous test module can also perform impedance characteristic tests and saturation current tests on inductive elements.

[0058] Intelligent motion control module: Use a servo motor to drive the lifting platform 8, and the adjustable range of the rotation speed is 5 - 30rpm, and realize wave-shaped plugging and unplugging through the motion trajectory planning algorithm.

[0059] Adaptive test interface module, which is set at the bottom of the test socket 7 and can make electrical connections to the pins of inductive components. It has a dynamic impedance matching circuit and a real-time contact state monitoring structure, can detect contact resistance with a resolution of 0.1 mΩ, and relies on two optical sensors to monitor pin deformation.

[0060] Data analysis and decision-making module, which has a real-time test data processing architecture. The analysis steps are: raw data acquisition --> digital filtering --> parameter calculation --> trend analysis --> good product determination --> data storage.

[0061] Packaging sorting linkage system, which can automatically grade and mark defective products based on the test results.

[0062] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
