AI Technical Summary
The existing ICT test fixture bottom box structure cannot accurately place the workpiece to be tested at the vertical lower end of the test needle plate before testing, resulting in test failure.
An automatically rotating camera and projector are installed on the bottom box structure of the ICT test fixture. The camera captures the image of the top of the bottom box and transmits it to the control panel. The control panel accurately calculates the placement position and projects it onto the bottom box through the projector to ensure the precise placement of the workpiece. After the test, the camera and projector automatically rotate to a position that does not affect the test.
It achieves precise placement of the workpiece to be tested, ensures the accuracy of the test, and avoids test failures caused by position deviation.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-Figure 4, an ICT test fixture bottom box structure shown in the figure includes a bottom box 1, the top of the bottom box 1 is fixedly installed with a top frame 4 through a side sliding column 2 and a central transfer column 15, the upper part of the central transfer column 15 is rotatably connected to a rotating block 8 and is limited by a limit plate on the outer wall of the central transfer column 15, the top of the rotating block 8 is fixedly connected to a gear 7, the power input end of the gear 7 is connected to the power output end of the quantitative rotation drive assembly, the outer wall of the rotating block 8 is connected to a mounting frame 12 through a third electric telescopic rod 11, and a camera 13 and a projector 14 are installed at the bottom of the mounting frame 12. The ICT test fixture bottom box 1 structure disclosed by the utility model is rotatably installed with a camera 13 and a projector 14 that can automatically rotate to the vertical upper end of the bottom box 1. Before the test, the top of the bottom box 1 is captured by the camera 13 and transmitted to the control panel. The precise position to be placed is projected on the bottom box 1 through the projector 14 through the control panel to ensure accurate placement. After the workpiece to be tested is placed, the camera 13 and the projector 14 can be automatically rotated to the rear end without affecting the test.
[0020] Furthermore, a first electric telescopic rod 5 is fixedly installed at the front end of the bottom of the top frame 4, and a test needle disk 6 is fixedly installed at the bottom of the first electric telescopic rod 5 for easy driving; further, a sliding sleeve 3 is fixedly installed on the outer wall of the test needle disk 6, and the sliding sleeve 3 is slidably connected to the outer wall of the side sliding column 2, so as to facilitate the smooth lifting and lowering of the test needle disk 6; further, the quantitative rotation drive assembly includes a rack 9 meshingly connected to the outer wall of the gear 7, and the power input end of the rack 9 is connected to the power output end of the second electric telescopic rod 10 for easy driving; further, the second electric telescopic rod 10 is fixedly installed at the rear end of the bottom of the top frame 4 for easy installation; further, a buzzer 16 is installed on the top of the mounting frame 12, which can sound an alarm when the placement is inaccurate.
[0021] In this solution, when in use, the ICT test fixture bottom box 1 disclosed by the utility model is rotatably installed with a camera 13 and a projector 14 that can automatically rotate to the vertical upper end of the bottom box 1. Before the test, the top of the bottom box 1 is captured by the camera 13 and transmitted to the control panel. The precise position to be placed is projected onto the bottom box 1 through the projector 14 through the control panel to ensure accurate placement. After the workpiece to be tested is placed, the camera 13 and the projector 14 can be automatically rotated to the rear end without affecting the test. Before use, the external power supply controls the extension of the second electric telescopic rod 10 through the external switch, driving the rack 9 to translate to the left, so that the gear 7 engaged with the outer wall of the rack 9 rotates clockwise along the outer wall of the central transfer column 15, and the gear 7, the rotating block 8, the mounting bracket 12, the camera 13 and the projector 14 are rotated to the bottom box 1 as a whole. Vertically at the upper end, the third electric telescopic rod 11 is controlled to extend, so that the mounting frame 12, camera 13 and projector 14 are extended to vertically below the test needle disk 6. The camera 13 collects the image of the top of the bottom box 1 and transmits it to the external control panel. After the control panel processes the area to be placed, it controls the projector 14 to be placed on the top of the bottom box 1. At this time, the workpiece to be tested can be placed easily and accurately. After placement, the third electric telescopic rod 11 is controlled to shorten and the second electric telescopic rod 10 is controlled to shorten at the same time, so that the gear 7, rotating block 8, mounting frame 12, camera 13 and projector 14 are rotated to the back as a whole, without blocking the test needle disk 6. At this time, accurate testing can be performed (the first electric telescopic rod 5, test needle disk 6, second electric telescopic rod 10, third electric telescopic rod 11, camera 13, projector 14 and buzzer 16 are all existing products on the market).
