[0022] When implementing: Figure 1-4As shown, an online FCT test device comprises: a frame 1, a test device 2 is fixedly connected to the upper end of the frame 1, a push cylinder 3 is fixedly connected to the inner wall of the test device 2, a push end of the push cylinder 3 is fixedly connected to a placement table 7, and a plurality of positioning rods 6 are slidably connected to the surface of the placement table 7; a vertical adjustment mechanism 4, which is used to adjust the spacing between the positioning rods 6 and is arranged on one side of the placement table 7; a lateral adjustment mechanism 5, which is used to slide the positioning rods 6 lateraly and is arranged on one side of the placement table 7; wherein the vertical adjustment mechanism 4 comprises a pushing component 401 arranged on one side of the placement table 7, and one side of the pushing component 401 A limit assembly 402 is provided. When the electronic board is to be inspected, it is first necessary to fix and place the electronic board on the placement table 7. At this time, the spacing of the positioning rods 6 is adjusted by the pushing assembly 401 and the lateral adjustment mechanism 5 to fit the installation holes of the electronic board. At the same time, the limit assembly 402 makes it less likely for the pushing assembly 401 to tilt or shake when moving to adjust the spacing, and it is more stable. At this time, the placement table 7 and the electronic board are transported by the pushing cylinder 3, and then the testing device 2 is used to fit the surface of the electronic board for inspection. For the staff in this technical field, the testing device 2 and the pushing cylinder 3 are both prior art and will not be elaborated on here.

[0023] like Figure 1 and Figure 3As shown, a mounting groove 4016 is provided at the side end of the placing table 7, and a worm 4017 is rotatably connected to the inner wall of the mounting groove 4016, and the lower end of the rotating rod 4014 rotates to penetrate the upper inner wall of the mounting groove 4016 and extend downward, and a worm wheel 4013 is fixedly connected to the circumferential surface of the rotating rod 4014, and the worm wheel 4013 is meshed with the worm 4017. When the spacing of the positioning rods 6 is adjusted, the worm 4017 is rotated, and the worm wheel 4013 is driven to rotate, and the worm wheel 4013 drives the rotating rod 4014 to rotate, and the pushing component 401 includes a rotating rod 4014 rotatably connected to the inner wall of the placing table 7, and the circumferential surface of the rotating rod 4014 is fixedly connected to a gear 4011, and the circumferential surface of the gear 4011 is meshedly connected to two racks 4012, and the far ends of the two racks 4012 are respectively fixedly connected to two first pushing rods 4015, and the first pushing rods 4015 are slidably connected to the placing table 7. The inner wall of the platform 7, the positioning rod 6 is slidably connected to the surface of the first pushing rod 4015. When the rotating rod 4014 rotates, the rotating rod 4014 drives the gear 4011 to rotate, so the gear 4011 drives the two racks 4012 to approach each other, and the two first pushing rods 4015 push the positioning rod 6 to approach each other. The limiting assembly 402 includes two limiting grooves 4022 opened on the surface of the placing platform 7. The lower ends of the two racks 4012 are fixedly connected to the limiting blocks 4021, and the two limiting blocks 4021 are slidably connected to the two limiting grooves 4022 respectively. When the gear 4011 drives the two racks 4012 to approach each other, the racks 4012 are easily skewed and cannot be accurately meshed with the gears 4011.

When the two second push rods 502 are driven to approach each other by rotating the bidirectional lead screw 501, the second push rods 502 are likely to shake with the rotation of the bidirectional lead screw 501. At this time, the second push rods 502 slide on the surface of the limit rod 503, so that the second push rods 502 are not easily skewed when sliding. The inner wall of the display table 7 is provided with a plurality of sliding grooves 504, and both ends of the first push rod 4015 are fixedly connected with sliders 505. The plurality of sliders 505 are respectively slidably matched with the plurality of sliding grooves 504. When the first push rod 4015 slides, it is easy to be skewed.

At this time, the worm 4017 is rotated, and the worm 4017 drives the worm wheel 4013 to rotate, and the worm wheel 4013 drives the rotating rod 4014 to rotate. At this time, the rotating rod 4014 drives the gear 4011 to rotate, so the gear 4011 drives the two racks 4012 to approach each other, and the two first push rods 4015 push the positioning rods 6 to approach each other. At the same time, the two second push rods 502 are driven to approach each other by the rotation of the two-way screw 501, and the two second push rods 502 drive the two positioning rods 6 to approach each other to adjust the spacing. At this time, multiple positioning rods 6 are close to each other and fit the fixing holes of the electronic board. The electronic board is fixed by sleeve setting the surface of the positioning rod 6. At this time, the placing table 7 and the electronic board are transported by pushing the cylinder 3, and then the test device 2 fits the surface of the electronic board for testing. At this time, when fixing electronic boards of different sizes, it is more convenient without placing molds.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
