Description

Technical Field

[0001] The present invention relates to a test device and a fault detection method, and more particularly to an electronic component test device and a fault detection method suitable for testing electronic components. Background Art

[0002] Generally, after being manufactured, electronic components usually need to be tested to determine their physical characteristics. For example, the prior art provided by the patent application "Circuit Component Loading and Unloading Device" with the publication number 411735 for testing electronic components of the capacitor type has a disc-shaped test board disposed on a vacuum suction plate, and one or several concentric ring seats of component slots can rotate relative to the center of the ring on the test board. The slots rotate at uniform angular intervals and incrementally, and the rotation increment is the angular interval between adjacent slots. The ring seat is inclined at a certain angle, and when the ring seat rotates, the component flow path dumps components towards the ring seat. The fixed grid plate adjacent to the outer plate side of the slot restricts the randomly rolling of the unreturned components due to the power to the empty slots in the arc segment of the rotation path of the ring seat. The random rolling causes the components to be returned to the slots. There are electronic contactors in the path of the rotating ring seat for connecting the components and the testing machine. The tested components pass under a spraying manifold, and the spraying manifold plate defines many spraying holes. Each time the ring seat rotates by an increment, the spraying holes are aligned with a group of slots. The spraying tubes are connected to the spraying outlets, and the components are blown out of the slots by the air of the selectively activated pneumatic valves. Due to the air blowing and gravity, the ejected components fall through the tubes and enter the sorting storage box under the guidance of the pipeline plate. The component flow path can be selectively directed to the grid plate in response to the signal of the detector indicating the lack of components on the grid plate, and the sensor can detect the components that have not been ejected by the spraying manifold in the seat slots.

[0003] In the prior art, the "sensor can detect components that have not been ejected by the ejection manifold in the seat grooves". Mainly, a blocking induction frame in a U shape and installed to straddle the vacuum suction plate, the test plate, and the loading rack is used. Two legs of the blocking induction frame define four openings respectively, and the hole positions on the legs are also aligned and matched with the four seat grooves marked by the two legs of the induction frame on each groove row; at the same time, there are four openings defined by the loading rack and conical openings defined by the vacuum suction plate that are matched with the hole positions on the legs of the induction frame; placed in the hole positions of the induction bridge legs behind / below the vacuum suction plate are four light-emitting wires that project light into the conical openings, and placed in the hole positions of the induction bridge legs are four optical fiber wires connected to the light sensor, and its light-receiving end faces the opening defined by the loading rack; the conical opening is used to focus the emitted light to the center of the aligned seat groove. Therefore, if there is a component in the seat groove, the component will block the emitted light; if there is no component in the seat groove, the emitted light will reach the corresponding light sensor. Thus, any component remaining in the seat groove after passing through the ejection manifold plate can be detected by the situation where the component blocks the light beam of each blocking sensor.

[0004] The prior art sets up the blocking induction frame and the sensor only to detect components remaining in the seat grooves after passing through the ejection manifold plate, so as to exclude the components stuck in the seat grooves in the subsequent flow path. However, if a solenoid valve that supplies the ejection gas fails during the process of the component being discharged through the pipe, the device cannot detect it. In this case, the blocking induction frame and the sensor will continuously detect the blockage and continuously perform exclusion in the subsequent flow path, but do not know the cause of the blockage, wasting the detection efficiency of the device. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide an electronic component testing device that at least improves one drawback of the prior art.

[0063] Please refer to Figure 1 、 2, in the embodiments of the present invention, an electronic component testing device for testing a component to be tested of the capacitor type is used for illustration, but it is not limited to the embodiments of capacitor-type electronic components; on the upper surface of a tabletop A1 inclined on a machine platform A, there is a disc-shaped test board B that can be driven to rotate intermittently in a clockwise direction, and an inlet unit C for loading the component to be tested, an inspection unit D for testing the characteristics of the component to be tested, and a discharge unit E for discharging and collecting the component to be tested that has completed the test are arranged outside the periphery of the test board B.

[0064] Please refer to Figure 2 , the inspection unit D is provided with a first inspection unit D1 for performing the withstand voltage and insulation resistance (commonly known as IR) inspection of the capacitor, and a second inspection unit D2 and a third inspection unit D3 for performing the capacitance, loss, or quality factor (commonly known as CD) inspection of the capacitor, which are respectively located in front of and behind the first inspection unit D1 in the direction of the intermittent rotation of the test board B; among them, the third inspection unit D3 located behind the first inspection unit D1 in the direction of the intermittent rotation can be omitted as needed.

[0065] The first inspection unit D1 is provided with a first frame D11 that can be lifted up and down, the second inspection unit D2 is provided with a second frame D21, and the third inspection unit D3 is provided with a third frame D31; the first frame D11, the second frame D21, and the third frame D31 are spaced apart by a certain distance and are not interlocked with each other.

[0066] The first frame D11 of the first inspection unit D1 is made of a metal material frame D111 to carry a plurality of terminal boxes D112 arranged in an arc for detection.

[0067] A material loosening unit K is arranged between the first inspection unit D1 and the discharge unit E where the test board B rotates intermittently in the clockwise direction (when the third inspection unit D3 is provided, it is between the third inspection unit D3 and the discharge unit E).

[0068] Please refer to Figure 3, the test board B can be driven to rotate intermittently in a clockwise direction and is arranged on the disk-shaped carrier chassis B2. The carrier chassis B2 is formed by detachably combining a plurality of fan-shaped blocks into an annular shape. Among them, the carrier chassis B2 corresponding to the lower part of the discharge unit E is provided with air blowing holes B21 for providing positive pressure gas. Each of the air blowing holes B21 is grouped in multiples (two in this embodiment) and corresponds to a seat groove B1 of the test board B above. The plurality of air blowing holes B21 are arranged at intervals along the arc-shaped conveying flow path direction. Under the requirement of corresponding to the size and shape of the component to be tested, the plurality of air blowing holes B21 can also be arranged at intervals along the direction perpendicular to the arc-shaped conveying flow path.

[0069] Please refer to Figure 4 , the discharge unit E is provided with a duct plate E1. A plurality of ducts E2 made of flexible materials are provided on the duct plate E1 (only one is shown as a phantom line in the figure). One end of each duct E2 corresponds to above a seat groove B1 on the test board B respectively, and the other end is led through the material guiding frame G and correspondingly conducted to a cartridge H1 of the collection mechanism H.

[0070] The collection mechanism H is provided with a rectangular frame-shaped seat H2. The cartridge H1 is provided inside the seat H2. Above the seat H2, a machine table top A2 is formed for setting the material guiding frame G. A plurality of columnar elongated sockets G1 are provided on the material guiding frame G. A plurality of through holes G2 for respectively embedding the ducts E2 are arranged in a straight line at intervals on the socket G1. The socket G1 is jointly formed by two side seats G11 and G12 that are detachably assembled and arranged on the left and right sides.

[0071] Please refer to Figure 5 , one side of the duct plate E1 of the discharge unit E is provided with a lifting frame E3. Among them, the lifting frame E3 is connected and linked to the duct plate E1 by a connecting piece E4. One end of the lifting frame E3 is pivotally arranged on a pivot seat H21 above the seat H2 of the collection mechanism H. A fixing frame H3 is provided on the seat H2. A driving member H4 composed of a pneumatic cylinder is pivotally arranged on the fixing frame H3. One end of a driving rod H41 of the driving member H4 is pivotally arranged on both sides inside a through hole E31 on the lifting frame E3. The driving member H4 drives the driving rod H41 to expand and contract, which can link the lifting frame E3 to drive the duct plate E1 to lift or cover the test board B.

[0072] Please refer to Figure 5 、 6, in an embodiment of the present invention, the test board B intermittently rotates in a clockwise direction and conveys the element to be tested by means of the seat groove B1. According to the direction of the intermittent rotation and conveyance flow path of the element to be tested, corresponding to the front end of the rotation and conveyance flow path within the range of the conduit board E1, a sensor E21 for determining whether the solenoid valve function for blowing air control corresponding to the seat groove B1 is abnormal is provided on the conduit board E1. The sensor E21 is located behind an end conduit E22 at the end of each conduit E2 classified and discharged on the conduit board E1, in front of a forced discharge conduit E23, and in front of an electrostatic eliminator E24; the sensor E21 is arranged in a row corresponding to the seat grooves B1 radially arranged on the test board B in a row. The sensor E21 may include an upper sensing element E211 located on the conduit board E1 and a lower sensing element E212 located on the carrying chassis B2 corresponding to and below the upper sensing element E211. When a seat groove B1 on the test board B performs intermittent rotation and conveyance, it can correspond to between the upper sensing element E211 and the lower sensing element E212. The upper sensing element E211 in the sensor E21 can also be lifted away from the lower sensing element E'212 and the corresponding relationship can be released as the conduit board E1 is lifted by the lifting frame E3.

[0073] When the present invention is implemented, when the element to be tested is conveyed by the intermittent rotation and conveyance flow path for detection and then arrives at the discharge unit E for classification and discharge, the seat groove B1 on the test board B reaches the sensor E21 after the classification is completed after passing through the end conduit E22. At this time, the sensor E21 will detect whether there is still an element to be tested in the seat groove B1. The processing system of the device can be set such that if the same classified element to be tested is not discharged as determined for more than two consecutive times, the processing system of the device will determine that the solenoid valve function for blowing air control corresponding to the seat groove B1 is abnormal and send a signal to notify the operator; regardless of whether there is still an element to be tested in the seat groove B1, when the seat groove B1 reaches the forced discharge conduit E23, it will be forced to be discharged. Then, the surface of the test board B and the seat groove B1 thereon will be subjected to electrostatic elimination by the electrostatic eliminator E24, so as to prevent the surface of the test board B and the seat groove B1 thereon from adhering to the element to be tested in the next cycle due to the static electricity generated by the long-term friction of the element to be tested.

[0074] For the electronic component test device and the fault detection method according to the embodiment of the present invention, by providing the sensor E21 to detect whether the solenoid valve function for blowing air control corresponding to the seat groove B1 is abnormal, it is possible to detect the abnormal solenoid valve function in the first time, avoid problems in subsequent production classification, and prevent the need to re-produce the entire batch of products, thus consuming a large amount of time.

[0075] The above are only embodiments of the present invention, and thus cannot be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification still fall within the scope covered by the patent of the present invention.
