[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-3 The utility model provides a small-volume FCT detection equipment, which includes a base 1 and a test device 2. Both sides of the base are provided with columns 3 extending upward. The test device is fixed to the columns on both sides by screws. The upper end surface of the base 1 is provided with a detection table 4. The test device is located above the detection table and is provided with a lifting platform 5. The lifting platform is connected to the test device 2 through a number of guide columns 6. The test device is connected to the lifting platform through a lifting mechanism. The lifting platform 5 can move up and down under the drive of the lifting mechanism. A detection board 7 is installed on the lifting platform 5. The detection board is fixed to the detection board by bolts or its clamps, so as to facilitate the replacement of different detection boards for detection according to different circuit boards. The FCT detection equipment adopting this structure can be operated and detected on the table, occupying a small ground space, and has a low cost and a small volume.

[0017] The lifting mechanism includes a motor 8, a screw rod 9 and a screw-connecting seat 10. The motor is installed on the testing device and connected to the screw rod to drive it to rotate. The screw-connecting seat is fixed on the lifting platform and screwed to the screw rod. When the motor drives the screw rod to rotate, under the limiting action of the guide column, the screw-connecting seat moves up and down along the screw rod, and at the same time drives the lifting platform to move up and down.

[0018] A first sensor is arranged on the column 3, and the first sensor is electrically connected to the lifting mechanism. A trigger part 11 for triggering the first sensor is arranged on the lifting platform. When the trigger part triggers the first sensor, the lifting mechanism stops lifting the lifting platform 5. The first sensor can limit the maximum lifting height of the lifting platform to prevent it from hitting the test device above.

[0019] The sensor includes a transmitting unit 12 and a receiving unit 13 which are arranged relatively to each other. The transmitting unit and the receiving unit constitute a photoelectric sensor. In a top-down view, the triggering part 11 is located between the transmitting unit and the receiving unit. The triggering part is a metal plate. The photoelectric sensor is a common type of sensor on the market with relatively mature technology.

[0020] A second sensor is provided on the column 3, and the second sensor is located below the first sensor. When the trigger part triggers the second sensor, the lifting mechanism stops lowering the lifting platform 5. The structure of the second sensor is consistent with that of the first sensor. By setting the second sensor, the descending height of the lifting platform can be limited to avoid collision between the lifting platform and the detection table.

[0021] The bottom of the guide column 6 is fixed on the lifting platform 5. The testing device 2 is provided with a sliding sleeve 14 that cooperates with the guide column 6. The top of the guide column is provided with an anti-slip portion 15. There are four guide columns, which are respectively located at the four corners of the lifting platform, to ensure that the lifting platform is lifted and lowered horizontally to avoid lateral deviation.

[0022] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
