Abstract

The embodiment of the invention discloses a multi-point synchronous measurement method, a measurement system, and a storage medium, and relates to the field of circuit board processing equipment. The multi-point synchronous measurement method includes: controlling the device to be tested to move according to one or more test points, controlling one or more laser head assemblies to emit one or more laser beams, so that each laser beam is divided into two beams One of the secondary laser beams is irradiated on the equipment to be tested, and the other secondary laser beam is returned to the laser head assembly; one or more laser beams that are irradiated on the test equipment and returned are collected, according to the The laser beam returned by the device and another sub-laser beam split out obtain the displacement value of each reflection point on the device under test. The multi-point synchronous measurement method, the measurement system, and the storage medium described in the embodiments of the present invention realize the accuracy test of multiple parts of the workbench of the processing equipment, and obtain accurate and intuitive test results.

Description

technical field [0001] The embodiments of the present invention relate to the field of circuit board processing equipment, and in particular to a multi-point synchronous measurement method and measurement system, and a storage medium. Background technique [0002] In the industrial production process, the PCB board (Printed Circuit Board, printed circuit board) usually uses a mechanical drilling machine to perform drilling processing. [0003] In the process of researching this application, the inventor found that during the production process, the six-axis PCB mechanical drilling machine performs point-to-point movement. At this time, the positioning accuracy of the workbench directly affects the drilling accuracy. Due to the fact that the rigidity of the workbench cannot be infinite, the two sides of the workbench are not completely symmetrical, the installation of the guide rail is deviated, and the driving force of the motor is not at the absolute center, etc., the posit...
