Description

Technical Field

[0001] This utility model relates to the field of automatic positioning device technology, and in particular to an automatic positioning device for PCB board testing fixture. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] Typically, the PCB board is placed directly into the slot on the board for testing.

[0004] However, sometimes when the workbench is hit by an external object, the PCB board in the PCB mounting slot may vibrate out, causing the PCB board to be out of the accurate position, thus preventing the probe from performing the test correctly.

[0005] If it is necessary to fix the PCB board in the slot, it is inconvenient for personnel to operate using a general fixing mechanism.

[0006] To address this, an automatic positioning device for PCB board testing fixtures has been developed, which makes it easy to place the PCB board in the PCB placement slot or to remove the PCB board, and also makes it easy to securely fix the PCB board placed in the PCB placement slot.

A toothed belt engaging gear 4 is fixedly connected to the outer wall of each of the two first splined bushings 3. A meshing toothed belt 5 is fitted onto the outer wall of both toothed belt engaging gears 4, causing the two first splined bushings 3 to rotate synchronously. It should be noted that the toothed belt engaging gear 4 and the meshing toothed belt 5 are a matching belt-driven mechanism, enabling the rotating column to rotate synchronously; this is a standard technical method employed by the technicians.

[0027] A first motor 14 is mounted on the base plate 1, and the power output end of the first motor 14 is connected to one of the first splined bushings 3.

[0028] Two first splined bushings 3 are slidably connected to a first splined shaft 6. The outer walls of the two first splined shafts 6 are fixedly connected to side plates 7. The bottom of the side plates 7 is fixedly installed with pressure posts 8. The two pressure posts 8 can position and fix the PCB board in the mounting groove 23.
