[0086] The working principle of the fixture installation detection device 10 provided in the embodiment of the utility model is as follows:

[0087] After the first fixture 13 is installed and locked, the second camera 211 will take a picture of the first mark point 131 on the first fixture 13 to obtain the real-time position of the first fixture 13, and then the real-time position of the first fixture 13 is compared with the preset reference position of the first fixture 13 through the second signal processor to confirm whether there is a deviation between the real-time position of the first fixture 13 and the preset reference position and save the data. Similarly, after the second fixture 23 is installed and locked, the first camera 111 will take a picture of the second mark point 231 of the second fixture 23 to obtain the real-time position of the second fixture 23, and then the first signal processor is used to compare the real-time position of the second fixture 23 with the preset reference position of the second fixture 23, so as to confirm whether there is a deviation between the real-time position of the second fixture 23 and the preset reference position, and save the data.

[0088] If there is a position deviation, the relative position between the fixture with the deviation and the fixture seat can be adjusted to make the fixture in the preset reference position. Alternatively, in the subsequent test and stepping process, the deviation coordinates can be established according to the deviation between the real-time position of the fixture and the preset reference position, and then based on the preset coordinate system association between the two fixtures (established through the preset reference positions of the two fixtures), a new coordinate system association between the two fixtures can be established in combination with the deviation coordinates to achieve precise alignment in subsequent tests.

[0090] The FPC testing equipment provided by the embodiment of the utility model is provided with a flattening device 30 and a fixture installation detection device 10 on a frame 20. The FPC is first flattened by the flattening device 30, and then the flattened FPC is tested by the cooperation of the first fixture 13 and the second fixture 23. The fixture installation detection device 10 detects whether there is a deviation between the real-time position of the second fixture 23 and the preset reference position of the second fixture 23 through the first detection component 11, and detects whether there is a deviation between the real-time position of the first fixture 13 and the preset reference position of the first fixture 13 through the second detection component 21, so as to know whether the first fixture 13 and the second fixture 23 are installed in place, and then the position can be adjusted according to the installation status of the first fixture 13 and the second fixture 23, so that the fixture is accurately positioned.
