Problems solved by technology
[0003] The existing printed circuit board inspection device needs to repeatedly adjust the focus process of the focus, which not only wastes a lot of time for the operator, but also has different perceptions of image clarity for each operator, which easily leads to misjudgments in subsequent inspections. Therefore, it is very necessary to invent and design an inspection device that can quickly focus to solve the problems in the prior art

The invention discloses a printed circuit board inspection device, which comprises a stage and a rail frame arranged above the stage; a moving seat, which is arranged on the rail frame and can move in the X-axis; a focusing seat, the The focusing base is set on the moving base; the probe module, the probe module is set on the focusing base, the probe module is provided with a probe, and the probe can touch touch the printed circuit board on the carrier; a camera module, the camera module is arranged on the focusing seat, the camera module includes a light source and a lens arranged on the light source; a control unit, The control unit is arranged on the focusing seat. The present invention can automatically and quickly adjust the optimum focusing height from the camera module to the printed circuit board according to the height measured by the probe module, and the operator does not need to repeat the focusing process many times, which not only saves time but also avoids misjudgment situation.
Description
technical field [0001] The invention relates to an inspection device, in particular to an inspection device used for inspecting a printed circuit board and on which an inspection lens can quickly focus. Background technique [0002] Currently, line scan cameras are commonly used in inspection devices for printed circuit boards, figure 1 It is an existing printed circuit board inspection device, in which the line scan camera P1 is set on the focusing seat 3 and can be lifted along the Z-axis direction, and the focusing seat 3 is set on the moving seat 2 and can be moved along the X-axis on the rail frame Move, so that the line scan camera P1 can move in the X-axis or Z-axis direction, the printed circuit board B is placed on the stage 4 and the stage 4 can translate along the Y-axis direction, when performing inspection operations, the line scan camera P1 After focusing on the printed circuit board B, start to move upward on the X axis and let the line scan camera P1 perform...
