The invention discloses a chain transmission type printed circuit board detection machine which comprises a metal tank body, a printed circuit board carrying platform, an X-axis servo motor, a Y-axisservo motor and an X-ray emitter, wherein the printed circuit board carrying platform is arranged inside the metal tank body; the X-axis servo motor and the Y-axis servo motor are used for driving theprinted circuit board carrying platform to move; the X-ray emitter is arranged below the printed circuit board carrying platform. The chain transmission type printed circuit board detection machine is characterized in that the printed circuit board carrying platform comprises a moving plate, a moving block, a longitudinal stainless steel track, a longitudinal chain, a transverse stainless steel track, a transverse chain and a fixing frame; the fixing frame is horizontally fixed inside the metal tank body; the longitudinal stainless steel track is arranged on one side of the fixing frame; theY-axis servo motor is used for driving the longitudinal chain to move; the longitudinal chain is used for driving the moving block to move along the longitudinal stainless steel track; the X-axis servo motor is used for driving the transverse chain to move; the transverse chain is used for driving the moving plate to move along the transverse stainless steel track. By adopting a chain transmissionmode and the cooperation with the servo motors, the displacement precision of the printed circuit board carrying platform is improved.
Description
technical field [0001] The invention relates to a printed circuit board testing machine. Background technique [0002] In the production of high-complexity PCB (printed circuit board), how to improve the product quality in the intermediate process, how to reduce the scrap rate, and how to improve the PCB quality are the goals that all PCB manufacturers have been pursuing unremittingly. But the quality of the current PCB is not optimistic. Because the quality of the printed circuit board depends on the quality of each line and each hole on the printed circuit board. However, any one of the thousands of lines and holes on a board has quality problems such as being too thin, too thick, incomplete, pinholes, adhesions, disconnections, and dislocations. Nowadays, X-ray testing equipment is generally used for testing to ensure product quality. [0003] The displacement accuracy of existing printed circuit board inspection machines is not very precise.
