The accuracy of SMT Mounter includes the positioning accuracy of Mounter, the repetition accuracy of mounter and the resolution of mounter. Through load balancing, in order to improve the patch efficiency, some measures are taken to pick up the configuration of the head as much as possible. The following small series will introduce the relevant contents in detail.

What is the precision of SMT patch and how to improve the efficiency of SMT patch?

1、 SMT patch accuracy

1. Positioning accuracy of the mounter

Positioning accuracy refers to the deviation between the actual position of the components and the position of the components set by the mounter. There are two factors affecting the mounting accuracy, translation error and rotation error. The translation error mainly comes from the X-Y axis positioning system, and rotation error refers to the insufficient accuracy of the component centering mechanism.

2. Repeat accuracy of Mounter

Repetition precision refers to the repeated mounting of a specific coordinate position by the SMT Mounter, and the resulting deviation is the repetition precision. Therefore, the sample precision given by the SMT Mounter is expressed by the repetition precision of the mounter.

3. Mounter resolution

After the mounting head receives the pulse command signal, the resolution of the R-axis is the resolution of the mounter, and the degree of rotation of the R-axis of the mounting head. The current good Mounter resolution reaches 0.0024/pulse, and the resolution can also be simply understood as measuring the minimum increment of the machine operation. Measuring the motion accuracy of the machine itself is an important performance index.

2、 Improve the efficiency of SMT patches

1. Load balancing. In order to ensure that the patch components of the two SMT mounters are reasonably allocated under the condition of the same patch time.

2. SMT Mounter itself. SMT Mounter itself has the maximum speed value, but it is usually difficult to achieve this. It has a certain connection with X / y structure mounter, and the configuration measures of picking up the head should be taken as much as possible in terms of Mounter speed. In addition, in the process of placement, put the same type of components together to reduce the times of assembly and save placement time.

The whole production process of SMT Mounter production line actually involves many equipment, but if any equipment runs too slowly in the processing process, it will delay the whole Mounter process and affect the realization of the actual process. Therefore, it is necessary to have scientific and systematic theoretical guidance and experienced personnel to operate on site in order to realize our expectations to the greatest extent.
