Description

Technical Field

[0001] This invention relates to an FCT inspection device for PCBs. Background Technology

[0002] Functional testing (FCT) generally refers specifically to testing PCBAs after power-on, mainly including tests for voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, sound recognition, temperature measurement, pressure measurement, motion control, and FLASH and EEPROM programming. Automated FCT testing equipment is mostly based on an open hardware and software architecture, allowing for flexible hardware expansion and quick and easy test program creation. It typically supports multiple instruments and can be flexibly configured as needed. Furthermore, it should have a rich set of basic test items, providing users with a universal, flexible, and standardized solution as much as possible. Existing FCT testing equipment is often inconvenient when changing PCBs for testing, as it cannot be done quickly and there is a risk of damaging the PCB during the replacement process. Utility Model Content:

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an FCT inspection device for PCBs.

[0004] An FCT inspection device for PCB includes a test fixture and a main unit chassis. The main unit chassis has a mounting platform on its front side. The test fixture is slidably mounted on the mounting platform. The test fixture includes a housing and a top cover. The upper surface of the housing has a test platform for placing the component under test. The lower surface of the top cover has a test probe bed. The rear end of the housing has multiple connectors. The front end of the main unit chassis has corresponding connectors.

[0005] The installation platform is equipped with a translation mechanism, which includes a sliding plate, a slider, and a cylinder. The upper end face of the sliding plate is connected to the lower end face of the box. The lower end face of the sliding plate is equipped with a connecting block and at least two parallel sliders. The upper end face of the installation platform is equipped with a corresponding slide rail. The cylinder is fixed to the installation platform, and its floating joint is fixedly connected to the connecting block.

[0006] Furthermore, the installation platform includes a fixed plate and two support plates. The two support plates are vertically spaced and fixed to the front end of the main unit. The fixed plate is installed above the two support plates. The sliding plate is installed above the fixed plate. The cylinder is installed below the fixed plate. The surface of the fixed plate is provided with clearance holes, and the connecting block passes through the clearance holes.

[0007] Furthermore, the support plate is a right-angled trapezoidal structure, and the fixing plate is a rectangular structure.

[0008] Furthermore, the test platform includes a mounting plate, the surface of which is provided with a workstation for clamping the test piece, and the workstation is provided with a first connecting plate on both sides for connecting to the upper cover.

[0009] Furthermore, one end of the top cover is hinged to the test platform.

[0010] Furthermore, the upper cover is provided with second connecting plates on both sides, and one end of the second connecting plate is hinged to a rotating seat via a connecting shaft. The rotating seat is installed on the rear side of the first connecting plate.

[0011] Furthermore, the upper surface of the skateboard is provided with multiple positioning posts, and the lower surface of the box is provided with corresponding positioning holes.

[0012] Furthermore, the first connecting plate is provided with a locking component and a proximity switch. The locking component includes a locking seat, and the side surface of the locking seat is provided with a through hole. A push rod is slidably inserted through the through hole, and the front end of the push rod is provided with a pin. The side surface of the second connecting plate is provided with a corresponding locking hole. The proximity switch is used to control the action of the push rod.

[0013] Furthermore, the box body is equipped with multiple handles on both sides.

[0014] Furthermore, a gas spring is provided between the first connecting plate and the second connecting plate located on the same side. One end of the gas spring is hinged to the first connecting plate, and the other end is hinged to the second connecting plate.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0016] The translation mechanism, including a slide plate, slider, and cylinder, enables rapid and smooth sliding of the test fixture on the mounting platform. This not only improves testing efficiency but also ensures the accuracy and stability of the test. The floating joint of the cylinder is fixedly connected to the connecting block, further enhancing the stability and controllability of the sliding motion.

[0017] The installation platform consists of components such as a fixed plate and a support plate, and its structure is stable and easy to adjust. The support plate adopts a right-angled trapezoidal structure, and the fixed plate has a rectangular structure. This design not only facilitates the installation and disassembly of testing fixtures, but also improves the stability and durability of the entire device.

[0018] The test fixture consists of a housing and a top cover. The upper surface of the housing has a test platform for placing the component under test (DUT). The lower surface of the top cover has a bed of test probes for easy electrical connection to the DUT. Additionally, multiple handles are located on both sides of the housing for easy handling and movement of the test fixture.

[0019] The locking mechanism and proximity switch on the first connecting plate enable reliable locking and unlocking of the top cover. The locking mechanism includes a locking seat, a push rod, and a pin. When the proximity switch senses the top cover approaching, it controls the push rod to actuate, causing the pin to insert into the locking hole on the second connecting plate, thus locking the cover. This design not only improves testing safety but also facilitates quick operation by the operator.

[0020] The rear end of the enclosure has multiple connectors, while the front end of the main unit has corresponding connectors. This design facilitates the electrical connection between the test fixture and the main unit. Furthermore, the test fixture and the main unit are structurally independent, allowing for easy maintenance and upgrades.

[0021] The workstations on the testing platform can be adjusted and clamped according to different test pieces, making the device suitable for various PCB testing needs. Attached Figure Description
