Description

Technical Field

[0001] This utility model relates to the field of PCB board FCT testing technology, and specifically to an FCT testing device. Background Technology

[0002] FCT testing primarily assesses the functionality of a PCB board. By simulating the PCB board's operating environment, providing power supply, input signals, output signals, control signals, and external devices, FCT verifies whether the PCB board's functions meet design requirements. During FCT testing, the test probes are connected to the connectors on the PCB board.

[0003] Existing FCT testing equipment mainly consists of movable test probes and a pressing module for holding down the PCB board. The test probes and the pressing module are usually connected to each other. During testing, the PCB board is placed on a carrier, the test probe is moved to the PCB board, the pressing module is first driven to press down the PCB board, and then the test probe is driven to descend to test the PCB board. However, existing FCT testing equipment usually only includes one set of test probes and a pressing module, and can only test one PCB board at a time, resulting in low testing efficiency.

Detailed Implementation

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please refer to Figure 1 This utility model provides an FCT testing device 100, including a carrier plate 10 and a drive module 20. Specifically, in this embodiment, the FCT testing device 100 is installed on a conveyor line 300. Only a part of the conveyor line 300 is shown in the figure.

[0022] The carrier plate 10 is used to place the PCB board 200, and two telescopic cylinders 11 are fixedly connected to the carrier plate 10. The output end of the telescopic cylinder 11 is fixedly connected to the support plate 12, and the support plate 12 is provided with a plurality of probe modules. The telescopic cylinder 11 is used to drive the probe modules to insert into the connectors 201 on the PCB board 200. Specifically, in this embodiment, the telescopic cylinder 11 is fixedly disposed at the bottom of the carrier plate 10, and the two PCB boards 200 are placed opposite each other on the carrier plate 10. The connectors 201 on the two PCB boards 200 are respectively located at both ends of the width direction of the carrier plate 10.

[0023] Please refer to Figure 2 A slide rail 13 is fixedly connected to the carrier plate 10, and a slider 123 is fixedly connected to the support plate 12. The slider 123 is slidably disposed on the slide rail 13. Specifically, there are four slide rails 13 arranged in pairs about the width of the carrier plate 10, and each support plate 12 corresponds to two slide rails 13.

[0024] Please refer to Figure 3 The drive module 20 includes a lifting cylinder 21 and a support frame 22 connected to the output end of the lifting cylinder 21. A double-acting cylinder 23 is fixedly connected to the support frame 22. The output end of the double-acting cylinder 23 is provided with two opposing piston rods 231. The piston rods 231 are connected to a pressure block 232. The lifting cylinder 21 is used to drive the pressure block 232 to rise and fall to press against the connector 201 on the PCB board 200. The double-acting cylinder 23 is used to drive the pressure block 232 to move to correspond with the connector 201 on the PCB board 200. Specifically, in this embodiment, the drive module 20 has two sets of cylinders arranged in pairs about the central axis of the carrier plate 10 in the length direction.

[0025] By setting up a double-acting cylinder 23 and two telescopic cylinders 11, during testing, the lifting cylinder 21 and the double-acting cylinder 23 respectively drive two pressure blocks 232 to press down the connectors 201 on the two PCB boards 200. The two telescopic cylinders 11 on the carrier board 10 drive two sets of probe modules to plug into the connectors 201 on the two PCB boards 200, thereby enabling simultaneous testing of two PCB boards 200 and improving testing efficiency.

[0026] Please refer to Figure 4 The probe module includes a connecting block 121 and a plurality of probes 122 disposed on the connecting block 121. The connecting block 121 is connected to a support block. The support plate 12 and the connecting block 121 are floatingly connected. Specifically, in this embodiment, a connecting bolt 1211 is provided between the support plate 12 and the connecting block 121, and a spring (not shown in the figure) is fitted onto the connecting bolt 1211. It can be understood that both the support plate 12 and the connecting block 121 are provided with bolt holes for the connecting bolt 1211 to be connected, and the diameter of the bolt hole is slightly larger than the size of the connecting bolt 1211 after the spring is fitted onto it, so that when the telescopic cylinder 11 drives the probe module and the connector 201 on the PCB board 200 to be inserted, the support plate 12 floats relative to the connecting block 121 in the radial direction of the connecting bolt 1211 to compensate for the positional error during insertion.

[0027] Please refer to Figure 1 The FCT testing equipment 100 also includes a frame 30, on which the carrier board 10 and drive module 20 are mounted. The frame 30 has multiple connector slots 31 for connecting cables electrically connected to the test probes 122. Specifically, in this embodiment, there are three connector slots 31, used for connecting cables transmitting test signals and action signals, as well as cables connecting to the PLC. The frame 30 also has a protective cover 32 corresponding to the probe module, which protects the connection between the test probes 122 and the cables, reducing the impact of the external environment on the test probes 122.
