Abstract

The invention discloses an automatic replacement device and method for a base plate for numerical control code drilling. The automatic replacement method of the base plate for the numerical control code drilling comprises the following steps that an unwinding motor is controlled to be switched between a position control mode and a tension control mode; after a base plate replacement instruction isreceived, the unwinding motor is controlled to be switched to the position control mode; and after the base plate is replaced, the unwinding motor is controlled to be switched to the tension controlmode. According to the automatic replacement method of the base plate for numerical control code drilling, the actual requirement for automatic replacement of the base plate is considered; by combining the characteristic of flexible switching of control modes of the unwinding driving mechanism and the characteristic of real-time tension control of the base plate, the device has the advantages of being more flexible and higher in universality, real-time tension control over a base plate winding belt can be achieved, and therefore the base plate can be kept in a tensioned state in the code drilling process, and a good code drilling process effect is obtained; and meanwhile, the universal requirements that the base plate replacement interval is accurate enough and the base plate replacement interval parameter is adjustable are met.

Description

technical field [0001] The invention relates to the technical field of circuit board drilling, in particular to an automatic replacement device and method for backing plates used for numerically controlled drilling codes. Background technique [0002] At present, the PCB manufacturing process has gradually entered the era of intelligent manufacturing. Most PCB process manufacturers have already proficiently applied the two-dimensional code marking technology to carry out product traceability, formula management, and even big data analysis of potion ratio performance on PCB boards. The two-dimensional code marking technologies that have gained mainstream application include: sticking two-dimensional code labels, inkjet coding and laser coding. However, in the above application methods, during the PCB board circulation process, abrasion, ink coverage or incompleteness may occur, which will affect the code reading recognition rate. One way to deal with it is to transcode betw...
